Question 3: When is the suitable season to plant hawthorn trees? Spring is generally the best time, from March to April. Planting and management in other seasons are difficult and the survival rate will be reduced.

Question 4: How to plant hawthorn trees 1. Apply base fertilizer in autumn

It is best to do it in time after picking the fruits in late autumn. This can promote the absorption and accumulation of nutrients by the tree and is beneficial to the flower buds. of differentiation. It is best to use organic fertilizer as the main base fertilizer, combined with a certain amount of chemical fertilizer. The chemical fertilizer should be mixed with organic fertilizer or soil appropriately before being applied into the trench to avoid root burning.

2. Timely girdling

Girdling or girdling young vigorous hawthorn trees can temporarily intercept the organic nutrients produced by the leaves for centralized supply, flowering and fruit setting, or flower bud formation. From late May to late June, use a blunt blade to girdle the smooth part of the trunk deep into the xylem, and apply "Kow of Flowers No. 2" to control shoots and promote flowers.

3. Top dressing during the flowering and fruiting stage

Top dressing before flowering is mainly nitrogen fertilizer, generally about 25% of the annual application amount; top dressing during the young fruit stage is mainly for early differentiation of flower buds to improve nutrition. Conditions: Top dressing during the fruit expansion period is mainly potassium fertilizer, which mainly promotes fruit growth and increases the carbohydrate content of hawthorn. Spray foliar fertilizer + "Strong Fruit Pedicle Ling" every year before flowering, during the young fruit stage, and during the fruit expansion stage, which can thicken the flower stalks and fruit stalks of hawthorn, prevent flower and fruit drop, and increase the speed of fruit expansion.

4. Pruning should be done carefully

Hawthorn trees should be pruned mainly in winter for transformation, renewal and rejuvenation. Remove leggy branches, diseased and insect-infested branches, and shrink and prune weak main and side branches. Select and retain appropriate buds for small renewal to cultivate strong branch groups. Modify the methods of re-cutting weak branches to make them stronger and incising wounds on bare buds to increase branches. Wounds during pruning are sealed and protected with a "wound antiseptic film" to prevent drying and cracking and damage by pests and diseases.

5. Water in a timely manner before harvesting

According to experiments, hawthorn gardens that can be watered in a timely manner before harvesting can increase production by 20% to 45% compared with control gardens. In the case of drought, its yield-increasing effect is more obvious. In addition, watering the hawthorn garden before harvest can increase the differentiation rate of hawthorn flower buds by more than 20%, and can reduce annual fruiting and pre-harvest fruit drop.

6. Sterilization, disinfection and prevention of pests and diseases

Spray "Tree Protector General" + 5 Baume Do lime sulfur mixture once during the winter dormancy period and before germination in spring to protect the flower buds. Disinfection and sterilization, heat preservation and antifreeze. From early May to early June, spray 2,500 times of insecticide to control spider mites and peach borer borers. Spray "new high-fat film" + insecticide + fungicide once each in mid-June, late July, and early August to prevent and control peach heartworm, ring rot, etc. For hawthorn gardens where powdery mildew is more severe, spray once before germination, once during the flower bud stage and once in June. Mix 600 times of 50% carbendazim wettable powder into 50% thiophanate methyl wettable powder.

Because hawthorn has good economic benefits, ecological benefits, and life benefits, it has received more and more attention from people in recent years. To this end, fruit farmers must do a good job in the management of hawthorn gardens to achieve stable and high hawthorn yields.

Question 6: Hawthorn trees When to plant hawthorn kernels are the seeds of hawthorn. It is best to sow seeds in spring or autumn. The planting soil must have enough fertilizer to ensure nutrition; the seeds need to be about 70 centimeters in the soil, and watering and fertilizing will be done later. Transplanting can be done after new saplings have grown.

Question 8: Hawthorn tree planting methods, hawthorn tree management methods, hawthorn tree cultivation technology characteristics

1. Propagation and planting: Grafting is often used to propagate hawthorn seedlings in large quantities. Rootstocks can be wild hawthorn or cultivated varieties. The inner seed kernels of cultivated species are often degraded. In severe cases, only 25% to 30% have kernels. The seeding rate should be increased during seedling cultivation. Due to the ossification of the core and shell outside the seed kernel, it is difficult to ventilate and absorb water. If the seeds are collected in layers using conventional methods, the germination rate after sowing is extremely low. Sometimes it takes 2 to 3 years after sowing for seedlings to emerge. Therefore, it is necessary to collect seeds in advance when the embryo is formed and the core shell has not hardened.

Normally harvested seeds, after breaking their shells, are treated with gibberellin at a concentration of one hundred parts per million (100Ppm) and then stored in sand, which can also greatly improve the germination rate of the next spring seeds. The sowing rate per thousand square meters is about 18 kilograms for small seeds and 37 to 45 kilograms for large seeds.

In addition, when propagating a small number of rootstocks, natural root tillers can also be used, or hawthorn root segments with a thickness of 0.5 cm to 1 cm can be directly cut into a length of about 15 cm, and root seedlings can be grown in the spring, or the root segments can be grafted with the scion of the variety. Cultivate seedlings from cuttings. The specific grafting operation technology is similar to that of apples and pears.

New roots of hawthorn occur earlier in spring, so seedlings in Huaibei are best planted in autumn. The spacing between plants is 3 to 4 meters in areas with poor soil, and can be 4 to 5 meters in areas with fertile soil and flat terrain. When planting, it is advisable to plant 2 to 3 varieties in separate rows to increase the fruit setting rate.

2. Hawthorn trees that are allowed to grow after pruning and pruning often have too many large branches throughout the tree and dense twigs in the crown, which affects yield and quality. According to the growth characteristics of hawthorn branches, the tree shape can be shaped in an evacuated layered shape, a natural round head shape with multiple main branches or a natural open heart shape. The evacuation layered tree structure is the same as that of apples, so you can refer to it. However, hawthorn trees have weak trunks and are prone to partial stem and partial crown phenomena. During plastic surgery, the cutting direction of the buds can be used or the extension branches of the central trunk can be replaced to control and adjust. When the central stem is severely tilted and difficult to cultivate, the central stem can also be removed according to its growth and changed to a natural open-shaped tree shape. Keep 3 to 4 main branches in the whole tree with a base angle of 45 to 50 degrees, and then appropriately cultivate secondary main branches on each main branch to occupy space. When using the natural round head shape of multiple main branches, you can keep a distance of about 30 cm between the main branches according to the natural growth of the branches, and arrange them appropriately and spread out in all directions. Cultivate 6 to 7 main branches in the whole tree. .

During the fruiting period, the main purpose of the hawthorn tree is to retract and rejuvenate the fruiting branches that have been bearing fruit for several years, preventing the fruiting parts from moving outward, stabilizing the yield, and maintaining good growth. Especially for branches that have been bearing fruit for many years and are drooping, the branches that are 3 to 5 years old should be retracted more heavily. When the large-year phenomenon occurs due to excessive fruiting, the excessive fruiting mother branches should be thinned out on the old trees to keep the ratio of mother branches to developing branches at 2:1 or 1:1. You can also perform re-pruning before flowering during the budding stage to remove some inflorescences on weak branches to promote flower bud differentiation. When the crown canopy is severely closed, some of the large branches will first be shed or retracted, and at the same time some of the developed branches will be thinned out.

3. Soil, fertilizer, water management and other basic fertilizers should be applied early in autumn. Top dressing can be applied according to specific conditions during the stages of germination, leaf expansion, flowering and fruit enlargement. Top dressing and foliar boron spraying (using 0.5% boric acid solution) during the spring flowering period can significantly increase the fruit setting rate and promote the growth of new shoots. For older trees, top dressing should be strengthened in the later period (August to September) to promote flower bud differentiation. When drought causes fruit drop, irrigation should be carried out or the soil should be loosened and covered with grass to reduce the drought.

During production, hawthorns will suffer severe flower and fruit drop, which will affect the yield. Reasons include weakened trees, poor pollination and fertilization, soil drought, insufficient light, etc. Corresponding measures must be taken according to different situations. For fruit drop or delayed flowers caused by poor pollination and fertilization, spray a gibberellin solution at a concentration of 50 parts per million (50 ppm) from the early flowering stage to the full flowering stage, focusing on spraying the flower clusters, which can increase the fruit setting rate. 1 to 2 times more, and make the fruit color and mature in advance.

4. Main pests and diseases and their control

Hawthorn diseases are generally not serious. Flower rot and powdery mildew sometimes occur. If flower rot damages leaves, leaves, flowers and fruits, you can spray Baume 5 degree lime sulfur mixture before germination on the basis of clearing the garden, and spray Baume 0.4 degree lime sulfur mixture or 700 times 50 times after the leaves unfold. % thiophanate methyl agent, which also prevents powdery mildew. Insect pests mainly include chafers and thorn moths that eat leaves or flower organs, heart-eating insects that damage fruits, and spider mites that suck sap. Prevention and control can be carried out based on the occurrence patterns on apple and pear trees.

Question 9: What do you need to plant a hawthorn tree? When to plant, where can you buy seeds, what should you pay attention to, how long does it take for germination after planting, and how long? It is best to apply base fertilizer in autumn after the fruits are picked in late autumn, which can promote the absorption of nutrients by the tree. Accumulation is conducive to the differentiation of flower buds. It is best to use organic fertilizer as the main base fertilizer, combined with a certain amount of chemical fertilizer. The chemical fertilizer should be mixed with organic fertilizer or soil appropriately before being applied into the trench to avoid root burning. 2. Timely girdling. Girdling or girdling young vigorous hawthorn trees can temporarily intercept the organic nutrients produced by the leaves for centralized supply, flowering and fruit setting, or flower bud formation. From late May to late June, use a blunt blade to girdle the smooth part of the trunk deep into the xylem, and apply "Kow of Flowers No. 2" to control shoots and promote flowers. 3. Top-dressing during the flowering and fruiting stage. Top-dressing before flowering is mainly nitrogen fertilizer, which is generally about 25% of the annual application amount. Top-dressing during the young fruit stage is mainly to improve the nutritional conditions for the early differentiation of flower buds. Top-dressing during the fruit expansion stage is mainly potassium fertilizer, which mainly promotes fruit growth. growth, increasing the carbohydrate content of hawthorn. Spray foliar fertilizer + "Strong Fruit Pedicle Ling" every year before flowering, during the young fruit stage, and during the fruit expansion stage, which can thicken the flower stalks and fruit stalks of hawthorn, prevent flower and fruit drop, and increase the speed of fruit expansion. 4. Pruning should be done carefully. Hawthorn trees should be pruned mainly in winter. They should be renovated, renovated and rejuvenated. The whorled backbone branches and peripheral dense branches should be thinned out, as well as competing branches, leggy branches, diseased and insect-infested branches, and weakened main and side branches. Select the appropriate parts of the buds for small renewal to cultivate a strong branch group. Modify the methods of re-cutting weak branches to rejuvenate them and incising wounds on bare buds to increase branches. Wounds during pruning are sealed and protected with a "wound antiseptic film" to prevent drying and cracking and damage by pests and diseases.

5. Timely watering before harvesting According to experiments, hawthorn gardens that can be watered in a timely manner before harvesting can increase production by 20% to 45% compared with control gardens. The more drought conditions occur, the more obvious the yield increase effect will be. In addition, watering the hawthorn garden before harvest can increase the differentiation rate of hawthorn flower buds by more than 20%, and can reduce annual fruiting and pre-harvest fruit drop. 6. Sterilization, disinfection and prevention of pests and diseases. Spray "Tree Protector" + 5 degrees Baume lime sulfur mixture once during the winter dormancy period and before germination in spring to protect the flower buds, disinfect and sterilize, and keep warm and prevent freezing. From early May to early June, spray 2,500 times the liquid to control red spider mites and peach borer borers. Spray "new high-fat film" + insecticide + fungicide once each in mid-June, late July, and early August to prevent and control peach heartworm, ring rot, etc. For hawthorn gardens where powdery mildew is more severe, spray once before germination, once during the flower bud stage and once in June. Mix 600 times of 50% carbendazim wettable powder into 50% thiophanate methyl wettable powder. Because hawthorn has good economic benefits, ecological benefits, and life benefits, it has received more and more attention from people in recent years. To this end, fruit farmers must do a good job in the management of hawthorn gardens to achieve stable and high hawthorn yields.

Question 10: Is hawthorn suitable for planting in the south? Hawthorn is a shallow-rooted tree species with undeveloped taproots, but it has strong growth ability and can grow in barren mountainous areas. The distribution layer of lateral roots is shallow, mostly distributed in the soil layer 30 to 60 cm below the surface, and the deepest can reach 90 cm. The amount of roots in the soil layer above 10 cm and below 90 cm is very small. Lateral roots are mainly distributed in a soil layer of about 40 cm, and the horizontal distribution range of the root system is about 2 to 3 times that of the tree crown. After hawthorn seedlings are planted, they take root late that year. Therefore, the growth of the above-ground parts was weak in the year of planting. After the seedlings slowed down in the second year, the growth became vigorous and became more vigorous year by year. However, when pruning, you should not cut too much because of the vigorous growth, or even prune the extension branches. This will affect the tree structure and skeleton, and affect the reasonable distribution of the branch groups. Although it may bear fruit early, the fruiting area will be small and the yield will be low. . The roots of hawthorn often produce adventitious buds and form root tillers, which mostly occur in the surface soil of 5 to 20 cm. Can be used to propagate seedlings or renew. (2) The top dominance of hawthorn is stronger than that of apple and pear trees. Because of its strong top dominance, the lifespan of the medium and short branches and small branch groups inside the crown is relatively short, and it is easy to die after fruiting. The stronger the top dominance of the tree, the more serious the phenomenon of bare interior. Therefore, when pruning, attention should be paid to suppressing the top dominance and maintaining the robust growth of the inner branch group in the crown. A common method to suppress apical dominance is to increase the opening angle of the backbone branches. After the apical advantage is weakened, the transformation ability of the medium and short branches in the inner chamber is enhanced, and the accessory buds and hidden buds may also sprout new branches. Using these branches to cultivate the fruiting branch group can make the inner chamber full and plump, expand the fruiting area, and increase fruit yield. (3) The terminal buds of hawthorn are fat, full, and have strong extension ability. After the terminal buds of hawthorn germinate, they often grow as single branches, with strong growth potential and a large amount of growth. This has obvious effects on the germination and growth of the lower lateral buds. inhibitory effect. In addition to the hypertrophy of the terminal buds of hawthorn, the lower 2 to 3 lateral buds are also relatively hypertrophic, their germination power is also very strong, and their growth is vigorous. However, the germination power of the lower lateral buds is very weak, so the lower part and inner cavity of the branches are Easier to go bald. Because the buds at the front of the developing branches of hawthorn have strong germination power, the branches on the periphery of the crown are often numerous and dense, resulting in deterioration of illumination in the inner bore, sparse branchlets, reduced fruiting area, and shifting of fruiting parts outward, affecting yield. (4) The hawthorn tree has strong adaptability and the hawthorn flower

Even in mountainous and thin areas, its growth and development is better than that of other fruit trees; hawthorn gardens with better fertilizer and water conditions can easily obtain high yields year after year, and are less likely to have large or small fruits. Phenomenon.

(Hawthorn trees can be planted in flower pots, but they are not as good as growing them outside.
