What are the methods for growing green vegetables? A detailed explanation
Green vegetables contain multiple nutrients and are rich in vitamin C. Let's take a look at the cultivation techniques for green vegetables.
1. Choose the soil plot: Choose paddy fields and dry land with deep soil layers, good irrigation conditions, and no pollution of soil, water, or air.
2. Select good seeds: Make full use of the advantages of local farm varieties of green vegetables, select disease-free, pest-free, robust original seeds of green vegetables from the current year, carry out purification and rejuvenation, and provide seeds uniformly.
3. Sow at the right time: Generally, early October is the best sowing period. Use idle land after the harvest of middle-season rice, soybeans, or peanuts as a seedbed. Raise seedlings at a seedbed-to-field ratio of 1:7, and make the seedbed soil fine and level.
4. Reasonable close planting: Transplant the seedlings after 30 days, and complete transplanting by mid-November. Generally, the row spacing is 66.7 cm and the plant spacing is 33.3 cm, with 3000 plants per mu. For plots with good soil fertility, plant appropriately sparsely. Choose early morning or late evening on cloudy or sunny days for transplanting, and water once with root-setting water after planting.
5. Scientific fertilization: Green vegetables are overwintering crops with a long growth period and strong nutrient uptake. The first fertilization is carried out 3-5 days after planting, applying 500 grams of pit fire soil ash mixed with human manure per plant; the second fertilization is carried out 60 days after transplanting, applying diluted human urine and manure. Green vegetables do not suffer from diseases or pests, so pesticides are not needed.
6. Harvest at the right time: The best harvest period for green vegetables is mid-March of the following year, when they are appropriately mature but not too old. Wash them and make them into vegetable blanks, which can prevent rotten lower leaves and also improve yield and quality.
