The planting method of green vegetables

Green vegetables contain a variety of nutrients and are rich in vitamin C. Let's take a look at the planting techniques of green vegetables.

1. Select soil blocks: select rice fields and dryland with deep soil layer, good irrigation conditions and no pollution of soil, water quality and air.

2. Select improved varieties: make full use of the advantages of local greengrocery farm varieties, select disease-free, insect-free and robust greengrocery in that year, purify and rejuvenate, and provide seeds uniformly.

3. Sowing at the right time: generally, the best sowing time is in the first ten days of October, and the seedbed is made of middle rice fields or free land after harvest of soybeans and peanuts. The seedlings were raised at 1:7 according to the ratio of the seedling bed to the field, and the bed soil was fine and flat.

4. Reasonable close planting: vegetable seedlings were transplanted after 30 days, and finished transplanting in the middle of November. Generally, 3000 plants were planted per mu with row spacing of 66.7cm, plant spacing of 33.3cm, suitable sparse planting of soil blocks with good fertility, transplanting early or late in cloudy or sunny days, and watering root water once after planting.

5. Scientific fertilization: Brassica chinensis is an overwintering crop with long growth period and strong absorptivity. the first fertilization is carried out 3-5 days after planting, with 500 grams of fire soil ash in human dung cellar per plant, and the second fertilization is carried out 60 days after transplanting. Green vegetables do not have diseases and insect pests and do not need to use pesticides.

6. timely harvest: the best time for harvesting green vegetables is the middle of March of the following year, old and tender, washed and made into vegetable embryos, which can not only prevent rotten foot leaves, but also improve yield and quality.
