Breeding methods and precautions of Fugui tree, Fugui tree has lush foliage, especially straight trunk and strong ornamental value, which is very suitable for raising at home. However, there are many problems that need to be paid attention to in the cultivation of rich trees. Let's take a look at the cultivation methods and precautions of the rich tree.

Rich tree 1 cultivation methods and precautions 1. Soil

This kind of plant needs to grow more vigorously in loose soil. To have good air permeability and drainage conditions, some calcium substances can be added to the soil to supplement nutrition.

Second, the temperature

The plant is acceptable in both cold and heat, and grows best at 15℃-30℃. The lowest acceptable temperature can be below -30℃, and it can grow normally at low temperature and survive in the hot south.

Third, light.

In its growing period, it is necessary to give enough light, which can last for 3-4 hours every day. When it is hot at noon in summer, we should pay attention to proper shading to avoid causing branches and leaves to wither and fall off.

Fourth, water.

It needs enough water to ensure its growth and development. It can be watered once every 2-3 days and once a day in summer to keep its soil moist.

Verb (abbreviation for verb) fertilization

There are not too many requirements for the composition of the fertilizer, and it can be fertilized once every 20-25 days, and compound fertilizer can be used.

Matters needing attention about intransitive verbs

1, it takes 2-3 years to change the pot soil, and at its growth rate, you can also change a bigger flowerpot.

2, do a good job of ventilation, so as to avoid symptoms such as leaf spot.

Cultivation methods and matters needing attention of rich trees II. Cultivation methods of the rich tree (basic knowledge);

The best breeding time: the cultivation of rich trees should be carried out after frost and defoliation in early autumn or before germination in spring; Green seedlings can be transplanted in spring, summer and autumn, and the roots need to be transplanted with soil during the growing period. Roots should be introduced before early May or after the middle of 10, and seedlings and green seedlings should be introduced before the end of April or after the middle of 10.

The most suitable soil for growth: loose and fertile loam and sandy loam with good drainage and rich organic matter should be selected to plant rich trees.

Growth humidity requirements: In the growing season of the rich tree, the basin soil should be kept moist and not dry. Especially in midsummer, you should always spray water on the leaves. If it is too dry, the tips and blades will dry up. However, the basin soil should not be too wet in winter, and the leaves should be sprayed with water frequently.

Optimum growth temperature: Fugui tree can resist cold and heat, can withstand the low temperature of MINUS 33℃, and has no freezing injury; Strong heat resistance, rapid growth in the south.

Optimum growth light: Rich trees should get enough light in spring and autumn, 3 ~ 4 hours a day, to keep their leaves bright. Appropriate shading in summer and autumn, spraying water once a day, cleaning the dust on the leaves, making the growth more vigorous and the leaves greener.

Matters needing attention in cultivating rich trees:

Fertilization: Fugui trees don't require much fertilizer, but if they are applied with NPK compound fertilizer every 20 ~ 25 days, they will grow vigorously.

Key points of watering: if the rich tree wants to have enough water, it must be watered every two days, and the soil must be watered thoroughly every time, not only half of the soil, but also enough water, so that the photosynthesis of the rich tree can be more sufficient.

Pruning points:

1. Rich trees have thick branches and vigorous growth under natural growth conditions, often forming a broad oval crown, but most of them have low trunks and too many branches, forming "small old trees". Shaping is to straighten its trunk, trim it in spring and summer, and trim the side branches that compete with the trunk, usually leaving no side branches below two meters.

2. plums. The time and quantity of pruning should be determined according to the purpose of afforestation. General afforestation should be pruned after the young forest is closed; In order to cultivate tall trunks and prevent excessive shading, the surrounding green spaces and shelterbelts should be trimmed properly in the first three years.

(1) Thinning: The trunk under 2 years old is relatively low. Generally, strong and upright branches are selected as the trunk, and the rest branches are drained according to different conditions. After the trunk is trimmed to a certain height, the thick competitive branches, clustered branches, upright branches and some over-dense side branches, drooping branches and dead branches are thinned.

(2) Pruning: Pruning the upright and robust side branches in summer. According to the principle of keeping the pressure weak, straight and flat, the upper part of the crown should be re-cut, while the lower part should be lightly cut for a long time. Branches should be cut off in several times, and small branches should not be cut off from the base to avoid wind folding or weak growth of the main tip.

(3) Pruning should be carried out in summer, preferably from early June to early July, which has the advantage of fast wound healing and generally does not sprout a large number of branches, which is beneficial to the growth of young trees. Pruning should not be too heavy, and it should be close to the trunk without leaving piles to avoid forming knots. The tools used should be sharp and the wound should be smooth, so that the branches will not crack.

3. Cute. After pruning, the long branches on the trunk or main side branches should be removed or cut off; For sparse branches at the base of trunk and the top of trunk heading in winter, sprouted new buds and buds should be cut off as soon as possible.

Change pots: change pots and soil for potted rich trees every 2-3 years; Apply NPK compound fertilizer every 20 ~ 25 days to keep the basin soil moist and prevent the leaf tail from drying up. It is best to place the balcony in the north facing the sun.

Key points of reproduction: the rich tree has good flowers but no pods, and there are no seeds for reproduction. Only by burying roots, cutting branches or grafting can asexual reproduction be carried out.

Pest control:

1, leaf spot. In the environment of high temperature, high humidity and poor ventilation, its leaves are easy to be infected with leaf spot. Prevention and control methods: both indoors and outdoors, we should strengthen ventilation and light transmission to avoid long-term water accumulation on leaves and reduce the possibility of leaf spot disease.

If a small number of diseased leaves are found, they should be removed and burned in time, and 600 times of 50 {BF} carbendazim wettable powder 1 time should be sprayed regularly every half month for 3-4 times continuously. Family potted plants, individual plants with a small number of diseased leaves, can be coated with Dakening cream ointment.

2, scale insects. Under the conditions of high temperature, high humidity and poor ventilation, especially during the long-term storage in shed in autumn and winter, the stem and leaves are prone to scale insect damage. Prevention and control methods: strengthen ventilation and light transmission, and pay attention to controlling environmental humidity.

If a small number of live insects are found, wipe them off with a wet cloth or stick them off with transparent tape. For productive cultivation, 1500 times of 25 {BF} chlorpyrifos wettable powder can be sprayed at the peak of nymph hatching.

Experience in cultivating rich trees;

1, Fugui tree is easy to be infected with leaf spot in high temperature and high humidity environment. In the cultivation of rich trees, both indoors and outdoors, ventilation and light transmission should be strengthened. If a small number of diseased leaves are found, they should be removed and burned in time. If a small number of live insects are found in Fu Gui trees, they should be wiped off with a wet cloth in time or glued off with scotch tape.

2. The soil of the rich tree should use black soil as much as possible. If black soil contains enough nutrients, it is very important for the growth of this rich tree.

3, the rich tree can not be exposed to the sun, if there is too much sunshine, the leaves will easily wither and look dull. So the sun should not be too much.

4. You need to spray water on the rich tree often with a watering can to wash off the dust on the leaves, so it will look more eye-catching.

5, the growth environment of the rich tree should not be too wet, which is easy to cause the leaves to yellow and fall off. The temperature should not be too low, and the growth will stop below 8 degrees. Rich trees must be planted in bright places and maintained in cool places for a period of time every other month, so they are managed alternately.

6, rich trees should pay attention to watering and fertilization, do not accumulate water in the basin, do not water often, it will rot the roots. Rich trees should be kept ventilated, and they will encounter pests if they are not ventilated for a long time.

Cultivation methods and matters needing attention of rich trees. Planting period.

The best cultivation time is 65438+1October after frosting in late June or before germination in early April. The transplanting period is spring, summer and autumn. Transplanting in growing season needs soil. The most suitable rooting period is before the first ten days of May or after the middle of 10.

Soil.

Cultivation should choose soil and sandy soil with rich organic matter, good drainage and slow fertility.

Water it.

During the growing period, the basin needs to be wet, but the soil can't be dry. When it is cool in summer, water the leaves often to prevent them from being too dry and withered. However, the soil in the basin should not be too wet in winter, and water should be sprayed on the leaves frequently to keep it naturally moist.

Temperature.

Endure the cold and heat, even at the temperature of MINUS 33℃, you can live normally. Heat-resistant, rapid growth.

Light.

There are 3-4 hours of light every day in spring and autumn, which can keep the leaves oily green. In summer and autumn, we should keep shade and adequate air humidity and soil humidity. Washing leaves in time can make plants grow sturdily.

Matters needing attention

Rich trees have low requirements for fertilizers, but after 20-25 days 1 time fertilization, the NPK compound fertilizer grows more vigorously. In order to keep enough moisture, Fu Gui wood must be watered every two days. Wet the soil every time you water it. Adequate water promotes the photosynthesis of trees.

Pruning technique

The rich trees planted in the yard are generally taller. Strong vitality, strong branching ability, the growth of rich trees gradually expanded, and the ornamental effect decreased. Potted rich trees are not as big as this environment, but they also have strong branching ability. Therefore, in order to bring good ornamental effect to plants, it is very important to be diligent in pruning.
