Time and method of planting green vegetables Recommended time and method of planting green vegetables.

Green vegetables are also called Chinese cabbage, rape and so on. Seeds can also be used to extract oil, which is also called rape. There are two varieties: Brassica and purple moss. The leaves in Shanghai are frosted and the basal leaves are feathered, which is somewhat different from Chinese cabbage. The planting season is generally from August to 10, which can be planted every year, but autumn and winter are the best, and northern winter is suitable for indoor planting.

2. Green vegetable seedling raising method

Summer is different from winter, and the temperature is high in summer, so it can be broadcast live. Live broadcast is adopted. In winter, due to the low temperature, you can choose to transplant after sowing. This way the survival rate is higher.

First, water the pot soil, mix the seeds evenly with fine soil, and then spread them on the soil surface. Just cover the seeds with a little soil, not too thick. You can moisten the top soil by spraying to keep the soil moist. Generally speaking, it takes about three to four days to germinate. When the temperature is relatively low, it takes about a week. You can also use the method of sowing on demand. The spacing between two or three seeds in each hole is about three to five centimeters. The time interval can be shorter when the temperature is high and longer when the temperature is relatively low.

Chinese cabbage seedlings should keep the soil moist, and water it once in the morning and evening when the temperature is high. After two weeks of germination, spray a thin layer of organic fertilizer with water.

When the seedlings grow to four or five true leaves, they can be transplanted at a fixed value. The spacing between plants depends on the size of the variety, which is generally 15 to 20 cm. After the fixed value, it should be watered, slightly shaded, and managed normally after survival. If transplanting is not needed, it is necessary to start thinning and pull out larger seedlings. The principle of thinning seedlings is to make the distribution of seedlings more uniform. You can choose to row for many times until the spacing is suitable, and topdressing the decomposed organic fertilizer after each thinning.
