Detailed Explanation of Key Points for Growing Meizao Large Cherry

AbstractSeed treatment: First soak the Meizao large cherry seeds in warm water for 1 day, then remove and wash them, crack the shells open and take out the seed kernels. Sowing: After the seed kernels are dried in the shade, sow them, cover with 1-2cm of soil and water appropriately, and they will germinate after 15 days. Seedling management: Keep the soil moist, and transplant once the seedlings have formed. Fertilizing: The development period is about 30-50 days, during which appropriate fertilization should be applied. Pest and disease control: Mainly control nettle caterpillars, mulberry white scale, scarab beetles, gummosis, anthracnose, etc.

I. Pot Cultivation Techniques for Meizao Large Cherry

1. Seed treatment

Soak the Meizao large cherry seeds in warm water for 1 day, then remove and wash the Meizao large cherry seeds, use a tool to crack the shells open; people with sharp teeth can bite them open directly, but do not damage the seed kernels inside.

2. Sowing

Place the treated Meizao large cherry seeds in a cool place for 1-2 days, then take them out and sow the Meizao large cherry seeds in the soil, then cover with 1-2cm of soil, water once after sowing is complete, keep the temperature between 20-25°C, and they will sprout after about 15 days.

3. Seedling management

After the seedlings emerge from the soil, water according to the degree of dryness or moisture of the soil so as to maintain soil moisture, but it should not be too wet either. After the seedlings have grown and formed, the seedlings can be transplanted with soil into a large pot for growing, but do not damage the seedling roots and stems.

4. Fertilizing

The fruit development period of Meizao large cherry is relatively short, generally about 30-50 days. During fruit development, it is divided into the 1st rapid growth period, the pit-hardening period, and the 2nd rapid growth period. During this time, the application amount of potassium fertilizer can be appropriately increased, the amount of nitrogen fertilizer reduced, and medium and trace elements such as calcium, boron, and zinc supplemented.

5. Pest and disease control

The main pests and diseases of Meizao large cherry trees include nettle caterpillars, mulberry white scale, scarab beetles, peach red-necked longhorn beetles, apple clearwing moths, golden-bordered jewel beetles, pear fruit borers, gummosis, anthracnose, cherry leaf spot, bacterial shot hole, root crown rot, etc. During this time, relevant measures need to be taken to control them.

II. Precautions for Management During the Flowering and Fruiting Period

1. During the early flowering period and around the full flowering period of Meizao large cherry, spray 1500-2000 times diluted Yunda Quanshuguo 1-2 times, which can promote the healthy development and elongation of pollen buds and pollen tubes, effectively increase the fruit-setting rate, and at the same time help pollination and fertilization and reduce flower and fruit drop.

2. During the young fruit swelling period of Meizao large cherry, spray 2000 times diluted Yunda Quanshuguo, which can reduce abscission at the fruit stalk of Meizao large cherry, avoid the formation of an abscission layer at the fruit stalk, reduce the second physiological fruit drop, and also promote simultaneous cell division and elongation, making the fruit stalk grow robustly and elongate, thereby accelerating fruit growth.

3. At the early stage of fruit coloring, leaf removal should be carried out. 10-15 days before harvest, reflective film can be laid to promote fruit coloring. About every 7 days before harvest, spray 3 times with 0.3% calcium chloride solution, which can reduce fruit cracking in Meizao large cherry and also extend the storage period.
