Choose varieties with good cold resistance, strong adaptability, good disease resistance, strong potential and strong reproductive ability to plant. The planting site requires that the environment is pollution-free, the soil is clean and free of diseases and insect pests, it is best to plant on the sunny hillside, and clean water is required nearby. The soil should be fertile, not barren and saline-alkali land.

After the appearance of the live broadcast, we should check the number of seedlings in time, whether there are no seedlings, those who do not emerge should replenish the seedlings in time; if the seedlings are raised, we should remove the weak seedlings, the diseased seedlings and the seedlings that do not grow well. After direct seeding, it is necessary to reduce moisture and prevent diseases; slow seedling fertilizer and water should be applied after seedling cultivation and transplanting to help recover as soon as possible. Weeds should be cleaned up in time when they are found. After the seedling stage, topdressing should be applied according to the growth stage.
