  1, sowing:
At the end of 3 month 4, a batch of seedlings of Zhiying cherry seedlings were carried out in the greenhouse. Due to the hybrid seed production, the female parent and the first-phase male parent can be sown first, and then the second-phase father can be sown after one month This can ensure the quality of later pollination. The prepared bed soil should be disinfected first. Potassium permanganate, formalin, dikeson, etc. can be used to spray the seedbed with an appropriate proportion of aqueous solution. The bed soil is sieved through a fine sieve, the bed is flat, and the bottom water is poured. After the water seeps, the seeds are evenly spread on the seedbed, and each gram of 750 seeds is germinated before sowing. After the seeds have been sown, sieve the prepared sandy soil evenly on the seedbed, covering the soil with a thickness of 0. 3 ㎝, and then covering it with plastic film, arch type, about 7 — {{6 }} Can germinate into seedlings in a day.
