1, the first ten days of September is the best sowing date of the two vegetables every year, and it will be harvested in the following year1-March, and the growing period is about 120 ~ 130 days.

2. Before sowing, select fertile and loose clods as seedbeds, plow, trim and rake, fully mix the decomposed farmyard manure with the bed soil, and pour the bed water thoroughly for sowing. The sowing amount is 70-100g per mu. Keep the soil of seedbed moist and ensure the emergence of seedlings. After the seedlings are unearthed, the water should be properly controlled to prevent the seedlings from growing too fast, and strong seedlings should be cultivated, and seedlings should be thinned 1-2 times at the seedling stage.

Children's vegetables should be sown 30-40 days after sowing. Generally, seedlings can be planted with 5-6 true leaves, and the seedling height is 18-20 cm. The planting density is generally 57-60 cm, and it is generally planted in June at 5438+ 10, with 2000-2400 plants per mu.

4. Pay attention to light fertilization before planting children's vegetables, pay attention to weeding without hurting roots, and shallow tillage. In case of high temperature before beginning of winter, plants grow excessively and form tall feet, paclobutrazol can be sprayed 500-800 times to prevent aphids and the whole growth period from collapsing. When the main stems and leaves of children's vegetables begin to turn Huang Shi, it means that they are mature. The axillary buds should be harvested in time, and the harvesting period in the second year is 1-3 months.
