Potting method

Variety selection

The varieties generally used for bonsai cultivation are required to have the characteristics of fruit shape, beautiful leaves, compact tree type, medium and short tree potential, shallow root system, early fruit bearing, easy fruit setting, fruit ripening during the festival, less diseases and pests, etc

The potted egg yolk fruit is mainly for viewing. The beauty of fruit, leaves and tree type is the primary consideration in variety selection, followed by the size, taste, edible rate, disease and insect resistance of the fruit, as well as the local adaptability of the variety. From the practical point of view, the spherical and spindle type should be selected for bonsai cultivation, followed by the large peach type and small peach type with high cultivation requirements

Seedling raising

The young seedlings of yolk fruit can be directly bought back from the market. Select 2-3-year-old branches with a thickness of 1.5-3.0 cm that grow obliquely to the sun or horizontally from the mature trees with strong tree potential and good fruit quality. At the place 15 cm away from the branches, select the smooth and straight side of the epidermis and cut two knives in a ring. The distance between the cuts is about 3-6 cm and the depth reaches the xylem. Peel off the cortex between the two cuts, polish and attach it to the cambium of the xylem with hemp fiber, And exposed for about 7 days, so that the remaining cambium cells dry and die. After 60 days, cut off the twigs and too many branches and leaves, keep 1 ~ 2 branches with good growth, cut off the leaves, carefully untie the film, keep the root ball intact, and put it into the nutrition bag to promote root and false planting

Upper basin

The period of egg yolk fruit suitable for pot is relatively long. In areas where there is no freezing injury or indoor overwintering in winter, it can go to the basin in autumn and grow vigorously in the next spring. In the cold area in winter, it is safer to go to the basin before branching in spring. In rainy areas in summer, it can be put into the basin after the growth of spring shoots stops and before the summer shoots are pulled out

After the pot is put on, it should be watered in sunny days. 7 ~ 10 days after potting, apply 5% rotten cake fertilizer or other thin liquid fertilizer when new roots occur. Potted plants should be placed in a ventilated and sunny place. The placement density should be wider to facilitate management, and the placement distance should be adjusted with the growth of plants

Maintenance

Fertilization

One month after planting, according to the principle of frequent application and thin application, apply fertilizer once a month, urea and potassium dihydrogen phosphate each time. From September to February of the next year, apply fertilizer once a month, urea and potassium dihydrogen phosphate each time

Apply flower promoting fertilizer before the first flowering and at the end of March, apply rotten fecal water in each pot, and apply potassium sulfate, calcium superphosphate and boric acid in the proportion of 100 ∶ 50 ∶ 5 after 7 days, with the application concentration of 0.1%

Water supply

Potted egg yolk fruit, water supply is very important. Watering time is generally before 10:00 a.m. or after 16:00 p.m; Winter or early spring should be carried out when the temperature is high in the afternoon, so as to avoid the drastic change of basin soil temperature and affect the growth and development of plants. In high temperature summer, basin trees lose more water due to rapid transpiration, and the basin soil should be kept moist. To this end, the basin should be left enough along the mouth, and the amount of watering should be subject to all wetting from the basin surface to the basin bottom, so as to prevent half cutting off the water

Protect flowers and fruits

Bagging and fruit protection: bagging shall be carried out after physiological fruit drop. Before bagging, spraying shall be carried out to prevent diseases and insect pests. Bagging shall be carried out on the same day to avoid re infection of the fruit. The bagging materials can be kraft paper and old newspapers. It is best to use them after being treated with pesticides and fungicides. When bagging, cover the fruit or the whole ear and tie the mouth of the bag tightly. In order to facilitate pericarp coloring, remove the bag 20 days before ripening

Trim shaping

The egg yolk fruit has strong germination power. In the young tree stage, we should pay attention to shaping and pruning, reasonably distribute the branches and cultivate a good crown. After fruit picking, dense branches, pest branches, shade branches, bare branches, etc. shall be cut in time to maintain a good tree structure

Pest control

The occurrence of diseases and insect pests in egg yolk fruit is less. For a small number of scale insects, 5% mineral oil emulsion or 5 baumido stone sulfur mixture can be sprayed when the branches sprout. During the growth period, it can be sprayed with 40% fast killing solution of 100 ~ 500 times; For the soot disease, spray with 400 times of sterilized Dan or 0.1: 1: 100 Bordeaux spray can prevent and control the disease. If there are termite hazards, we can use 48% lotion 1000~1500 times spray. p>
