Planting techniques of Meizaoda Cherry

Seed treatment: first soak the Meizao cherry seeds in warm water for one day, then remove and wash them, knock open the shell and take out the seeds. Sowing: the seeds were dried in the shade, sowed, covered with soil for 1-2cm and watered properly, and germinated after 15 days. Seedling management: keep the soil moist and transplant after the seedlings are formed. Fertilization: the development period is about 30-50 days, and appropriate fertilization is applied during the period. Prevention and control of diseases and insect pests: mainly control diamondback moth, mulberry scale, beetle, gum disease, anthrax and so on.

1. Potted planting techniques of Meizaoda Cherry

1. Seed treatment

Soak the cherry seeds in warm water for 1 day, then remove and wash the cherry seeds and break the shell with a tool. People with sharp teeth can bite open directly with their mouths, but do not damage the seeds inside.

2. Sowing seeds

Put the treated Meizaoda cherry seeds in a cool place for 1-2 days, then take out and sow them in the soil, then cover the soil with 1-2cm, water once after sowing, keep the temperature between 20-25 ℃, wait about 15 days to germinate.

3. Seedling management

After the seedlings are soaked, they can be watered according to the degree of dryness and wetness of the soil, so as to maintain the wetness of the soil, but it should not be too wet. After the seedlings have grown and formed, the seedlings can be transplanted with soil into a large basin for culture, but do not harm the roots of the seedlings.

4. Fertilization

The fruit development period of Meizaoda cherry is relatively short, generally about 30-50 days. In the process of fruit development, it can be divided into the first speed period, the hard core stage and the second speed period. During this period, the amount of potassium fertilizer can be increased and the amount of nitrogen fertilizer can be reduced. and supplement calcium, boron, zinc and other trace elements.

5. prevention and control of diseases and insect pests

The main diseases and insect pests of Meizao cherry trees are diamondback moth, mulberry scale, beetle, peach red-necked longicorn beetle, apple winged moth, golden edge beetle, pear heart borer, gum disease, anthracnose, cherry leaf spot, bacterial perforation, root and neck rot, etc. during this period, relevant measures need to be taken to control.

II. Matters needing attention in the management of flowering and fruiting period

1. 1500-2000 times liquid cloud can be sprayed before and after the early flowering and full flowering stage of Meizaoda cherry. The fruit of the whole tree for 1-2 times can promote the healthy development and elongation of pollen buds and pollen tubes, effectively increase the fruit setting rate, and at the same time facilitate pollination, fertilization and reduce the shedding of flowers and fruits.

2. In the young fruit expansion period of Meizaoda cherry, 2000 times liquid cloud can be sprayed. The whole tree fruit can reduce the shedding of the pedicel of Meizaoda cherry, avoid the formation of pedicel detachment, reduce the second physiological fruit drop, promote cell division and elongation at the same time, make the stalk grow strong and elongate, so as to accelerate the growth of fruit.

3. In the initial stage of fruit coloring, leaves should be picked. 10-15 days before harvest, reflective film can be spread to promote fruit coloring. Spraying 0.3% calcium chloride solution three times before harvest can reduce fruit cracking and prolong storage period of Meizaoda cherry.
