How to grow the cabbage? The heart of the dish is actually the dish we usually say. It is generally suitable for sowing in the warm southern region. Many restaurants have garlic dishes. Let's take a look at the key points of the cultivation of the heart.
First, live
Because of the short growth period of the cabbage, its root system is shallow, and its ability to absorb water and fertilizer is poor. Therefore, it is necessary to apply enough base fertilizer to apply 1500-2000 kg of high-activity organic fertilizer per acre. For sowing or spreading, the amount of seeds per mu is 0.4 to 0.5 kg. Try to achieve even and even broadcast, mixed with sand and mixed.
Second, nursery
The seedbed should be sand or loam and the base fertilizer should be applied. The seeding amount per mu of seedbed is about 0.5 kg, and the seedlings for breeding can be planted in 7-8 mu. After the true leaves are unfolded, the appropriate seedlings are combined with the seedlings to apply a small amount of human excrement. Because the roots of the cabbage are not developed, such as the seedling period is too long, the roots are easily damaged when transplanted, not only the growth recovery is slow and easy to twitch early. Therefore, the age of seedlings should not exceed 30 days, generally 20 to 25 days is appropriate.
Third, colonization
When the seedling grows to 4 to 5 true leaves, it should be planted in time. The row spacing of early-maturing cultivars was 13 cm × 16 cm, and the row spacing of mid-late maturing cultivars was 20 cm × 25 cm.
Fourth, field management
During the growth period, when the plant is budded, the first-time nitrogen fertilizer can be applied once, and 1000 kg of manure or 15-20 kg of urea per acre can be applied. If you want to receive the side sputum, after the main sputum is basically taken, the human feces and urine will be applied once again to promote the development of the sacral sputum. Each time after harvesting 1 茬, topdressing 1 time.
Five, disease prevention and control
The main disease of Chinese cabbage is downy mildew. It can be sprayed with 500 times liquid of Luheng No. 9 wettable powder (or Green Hengguan Road wettable powder) or 58% green moisturizing cream WP 0.5 times. There are cabbage caterpillars and aphids. Aphids can be sprayed with enemy killings, deltamethrin, etc., and cabbage caterpillars can be sprayed with insecticides such as chlorfenapyr and phoxim. For example, if you add Luheng Liping or spray cola to the above-mentioned medicines, the control effect will be better.
Sixth, harvest
When the height of the rapeseed reaches the same height of the plant, it is called “Qikouhuaâ€. At this time, it is the optimum harvesting period and should be harvested in time.
The above is all about today's cultivation of the heart of the cabbage, if you have better experience, welcome to share the message below the Hui Nong network!
