The market prospect of cherry trees is broad, so many people want to plant cherry trees; So how to plant potted cherry trees? The following are the planting techniques of potted cherry trees that I have carefully arranged for you. Let's have a look.

Planting techniques of potted cherry tree 1 Variety selection: Cherry is a cross-pollinated fruit tree. In the process of potted plants, attention should be paid to variety collocation, and 2-3 varieties should be grafted in each pot. Cherry varieties with large fruit, bright color and strong continuous fruiting ability should be selected for the upper basin cherry.

2. Cherry pot: container selection: the container should match the size of cherry seedlings. 1 ~ 2-year-old cherry seedlings should be selected in containers with a diameter of 25 ~ 30cm. The container has good air permeability and no toxic effect on root system. Practice has proved that vegetarian cooking pots and wooden barrels have the best effect; Purple sand basin and plastic basin are the second; The one containing enamel is the worst and has the lowest survival rate. Preparation of nutrient soil: Cherry root system has strong respiration and high oxygen consumption. Soil permeability should be high. Nutrient soil configuration: peat soil: manure: sand =5∶3∶2. Selection of seedlings: robust growth, full branches and buds, developed roots and no pests and diseases. Small perennial trees require short stems, reasonable branch distribution and large thinning degree between branches. Potting: In early spring, before potting, the damaged roots and branches should be pruned to expose new stubble; Cut off the parts with pests and diseases. Secondly, check the drain hole of the container to keep the container drained smoothly. Pot filling method: Invert a tile on the drain hole, then spread 20cm furnace ash slag, fill with nutrient soil, and finally put the seedlings. After 2 ~ 3 times of raising seedlings and pressing soil, the soil surface is about 5 cm away from the mouth of the container.

3. Fertilizer and water management: Fertilizer and water in potted plants are the most difficult to master. Physiological activities such as cherry growth, flowering and fruiting all depend on daily fertilizer and water management. Fertilize cherries with water and apply less; See dry and wet; It's full, it's leaking. In spring, cherry trees that have not yet borne fruit apply a small amount of PBO in the container. Fertilize frequently before July to promote the growth of trees. Commonly used fertilizers are cake fertilizer, livestock hoof horn, sesame sauce residue, yogurt, rice washing water, broken bone chips and so on. It is best to soak them until they are fermented and apply them as fertilizer solutions. Apply 1 0 ~15 days/times of organic fertilizer water. After August, potassium dihydrogen phosphate is added into the organic fertilizer water; For cherry trees entering the fruiting period, urea 1 time was applied before and after flowering, and phosphorus and potassium fertilizer were added to the fertilizer water; In September, 50g of potassium sulfate was applied at one time. Irrigate/kloc-0 times a day in summer, and often spray some water on the leaves to cool and clean the trees. Irrigation times should be less in spring and autumn. Basically no watering in winter. The best irrigation amount is to drop a little water from the bottom of the container. Preparation of organic fertilizer water: Soak soybean meal in clear water according to the ratio of 1: 5, then ferment for 5 ~ 10d, and then add 10 times of water for dilution.

4. Flower and fruit management: The focus of flower and fruit management is thinning flowers and fruits. Bud thinning is stronger than flower thinning, and flower thinning is stronger than fruit thinning. There are a large number of flower buds in the tree, and some flower buds are thinned out in bud stage. Operation method: Sparse 1/3 ~ 1/4 flower buds on the bearing branches of flowers. During flowering, cross-species pollination should be done well. When the cherry grows to the size of soybean, the fruit with abnormal shape is thinned out.

5. Trimming: The terminal buds of cherry and the central buds of flower clusters are leaf buds. Flower buds are pure flower buds, mainly axillary buds and bouquets. Axillary buds are inserted at the base of 1 annual branches. Pay attention to the position of flower buds when pruning. Pruning is mainly in summer, supplemented by pruning in winter. Winter pruning: mainly to adjust the tree type and balance the tree potential. Mainly remove competitive branches, upper branches, strong branches and slender branches. The extended branch becomes shorter, causing the branch to retract. Summer pruning: mainly to maintain the tree shape, promote flowers and protect fruits. Cut off the competing branches and back branches. Pick the core when the branch grows to 15 ~ 20 cm. Generally completed before July, 1 year is no more than twice. Around September, when the branches have just reached the peak, flatten them.

6. Pest control: cherry perforation disease, the spots with large primary needles on the leaves gradually expand into round brown spots, and the affected parts produce grayish brown mildew spots, which shrink and delaminate at the periphery, often falling off into brown perforations with irregular edges. After flowering, 70% mancozeb was sprayed with 500-fold solution every 7 ~ 10d/time for 3 ~ 4 times continuously. Tetranychus urticae: It feeds on the back of the host leaves, pierces cells and sucks juice. The damaged leaves first appear pale spots from both sides of the main vein near the petiole, and can turn gray and dark brown with the aggravation of the damage. Spraying avermectin 3000 ~ 4000 times in the growing season.

7. Overwintering technology: Cherry is prone to stripes during overwintering. The main reason is that the underground root system is short of water supply in winter, so it is necessary to irrigate and cover the ground before overwintering to reduce water evaporation. Measures such as early pruning of fruit tree branches, spraying anti-transpiration oil emulsion and wrapping the branches with film are also effective.

Planting and maintenance methods of potted cherry; Growth habit of big cherry

Big cherry is a fruit tree that likes light, temperature, humidity and fat. It is suitable to grow under the climatic conditions of annual temperature 10 ~ 12℃, annual precipitation of 600 ~ 700 mm and annual sunshine hours of more than 2,600 ~ 2,800 hours. The place where the daily average temperature is higher than 10℃ 150 ~ 200 days and the extreme minimum temperature in winter is not lower than -20℃ can grow well and the results are normal.

Pot cultivation of big cherry

1, container selection: The container of big cherry cultivation has good air permeability and no toxic effect on the root system. Burning pots and wooden barrels have the best effect, followed by purple sand pots and plastic pots, and enamel is the worst, because big cherries are not easy to survive after being put into pots.

2. Pot soil preparation: The root system of big cherry has strong respiration and large oxygen consumption. Soil requires high permeability, especially sandy loam with loose soil and deep soil layer. The ratio of nutrient soil is peat soil: manure: sand =5:3:2.

3. Selection of seedlings: Tree species with strong growth, full branches and buds, developed roots and no diseases and insect pests should be selected for the cultivation of big cherry seedlings, and small perennial trees should have short stems, reasonable branches distribution and large cutting degree between branches.

4. Pot planting time: The pot planting time of big cherry is mostly in early spring. Before potted plants, damaged roots and branches should be pruned to expose new stubble, and the parts with pests and diseases should be cut off. Secondly, check the drain hole of the container to keep the container drained smoothly.

5. Potting method: Invert a tile on the drainage hole, then spread a layer of 20 cm furnace ash slag, fill with nutrient soil, and finally put the seedlings. After 2-3 times of seedling raising and soil pressing, the soil surface is about 5 cm away from the mouth of the container.

Cultivation and management of big cherry

1, fertilizer and water management: Big cherry should be watered frequently when there are many branches and leaves and the temperature is high, otherwise the soil will be too dry, which will affect its growth, flowering and fruiting. Fertilization should master the principle of applying thin fertilizer frequently. From spring to autumn, it is generally required to apply decomposed rapeseed cake fertilizer every 10 ~ 15 days. In autumn, 0.5% potassium dihydrogen phosphate aqueous solution should be sprayed 2 ~ 3 times to promote plant growth and flower bud differentiation.

2. Heat preservation and moisture retention: Big cherries are cold-resistant, and plastic film greenhouses can be used for cold protection in cold regions. Keeping the temperature at about 25℃ during the fruit-setting period and the humidity at 50% ~ 60% during the growth period is beneficial to flower bud differentiation and increase the yield. If there is freezing injury in the local area, potted cherries must be kept warm and moist.

3. Flower and fruit management: The flower and fruit thinning of big cherry is the key point of flower and fruit management, and bud thinning is stronger than flower thinning, and flower thinning is stronger than fruit thinning. There are a large number of flower buds in the tree, and some flower buds are thinned out in bud stage. The operation method is that the flower buds of 1/3 ~ 1/4 are neglected on the cluster-like fruiting branches, and cross-pollination is carried out at the flowering stage. When the fruit grows to the size of soybean, the heteromorphic fruit is neglected.

4, shaping and pruning: the top bud of the big cherry and the central bud of the fruiting branch group of the flower cluster are leaf buds. Flower buds are pure flower buds, mainly axillary buds and bouquets. Axillary buds are usually planted at the base of 1 annual branches, and attention should be paid to the position of flower buds when pruning. Pruning is mainly in summer, supplemented by pruning in winter.

① Winter pruning: Winter pruning is mainly to adjust the tree type and balance the tree potential. Mainly remove competitive branches, upper branches, strong branches and slender branches. Elongated branches are cut short, resulting in branch retraction.

② Summer pruning: The purpose of summer pruning is to keep the tree shape, promote flowers and protect fruits. Cut off the competing branches and back branches. Pick the core when the branch grows to 15 ~ 20cm. Generally completed before July, 1 year is no more than twice. Around September, when the branches have just reached the peak, flatten them.

Key points of potted cherry tree planting Cherry tree is a highly adaptable tree species, which belongs to deciduous trees and has a long planting history in China. The growth habit of cherry trees is that they like sunshine, moist and fertile soil, and the average annual temperature suitable for cherry growth is 10- 12 degrees Celsius. In order to plant potted cherries, we should not only understand the growth habits of cherry trees, but also pay attention to the variety selection, flowerpot selection and soil and water management of potted cherries.

In the selection of potted cherry varieties, it is suggested to choose some cherry varieties with good fruiting ability, such as big cherry varieties, because big cherry has large fruit, beautiful color and high planting value. In addition, cherries are cross-pollinated fruits. In the process of planting potted cherries, we should also pay attention to the collocation of varieties. Other varieties can be grafted on potted cherry trees to help cherry pollinate.

In the selection of pots for planting cherry, we should choose some round pots with good air permeability, and the diameter can be between 30-40. Generally speaking, it is best to choose containers such as cooking pots and wooden barrels to grow cherries. In addition, the best time for cherry tree pots is generally in early spring.

In the choice of pot soil, the pot soil of potted cherry should have high air permeability, because the root system of cherry needs more oxygen, and the pot soil with good air permeability can ensure the root system of cherry to breathe well. Generally, turf soil, sand, manure and other soils can be selected and mixed according to a certain proportion. Generally speaking, the ratio is 5 parts turf soil, 2 parts sand and 3 parts manure.

In the management of watering and fertilization, because the cultivation of potted cherries is limited to potted plants, more attention should be paid to the management of watering and fertilization of cherries. Water the cherries frequently, especially when there are many branches and leaves and the temperature is high, and pay more attention to watering the cherries to keep the soil moist. In the aspect of fertilization, we should pay attention to the principle of applying thin fertilizer frequently. We should not apply too much fertilizer at a time, and apply fertilizer more often. Generally speaking, fertilization once a month can meet the nutritional growth needs of cherries. When applying fertilizer, you can choose organic fertilizers such as rotten rapeseed cake water and rice washing water.

In the aspect of flower and fruit management, we should pay attention to the management of flower and fruit period of potted cherry, and the key point is to do a good job of thinning flowers and fruits, that is, when the number of flower buds is large, some flower buds should be properly thinned, and some underdeveloped fruits should be thinned in time when they bear fruit, so that good fruits can continue to grow.

In terms of pest control, perforation and tetranychus urticae are common pests and diseases of cherry, mainly due to the appearance of gray-brown mold on leaves, which leads to brown perforation of leaves. Pesticides such as mancozeb and abamectin should be sprayed in time when pests occur in potted cherries.
