The emergence of Chinese cabbage requires higher soil moisture. When the soil is dry, the seed is not easy to germinate, and even if it is germinating, it is easy to see dead shoots. Therefore, sowing requires better soil moisture, spray water after sowing, keep the surface wet, ensure emergence. The seedling period is at a high temperature and dry season. To reduce the temperature and prevent disease, it is necessary to diligently water the soil, keep the soil moist, prevent the soil from cracking, tear the root system, and infect soft rot and virus diseases. Generally, it takes 3 to 4 days to water once. "Three water seedlings, five waters will be planted." In this period, if the amount of roots per acre more than 5 kg diluted 200 to 500 times to irrigate roots or watering with irrigation water can promote plant robust and reduce the incidence of soft rot. Generally speaking, Chinese cabbage should be seedlings for 4 to 6 days after setting seedling water, in order to promote the development of the root system deep underground, enhance the ability of drought resistance, make the leaves of the aboveground plants grow robustly, and enhance disease resistance. After the “seedlingsâ€, the combination of top-dressing with heavy water is used once. After that, it is usually watered once every 6~7 days to keep the soil moist. The Chinese cabbage rosette period is the period of rapid development and development of the outer leaves. It is a crucial period for the robust development of Chinese cabbage. It is an important period for the requirement of fertilizer, and it is necessary to attach great importance to this “fabricated tree fatâ€. After setting the seedling water, when the soil moisture is suitable, in the middle of the ridge, a shallow ditch of 8 to 10 centimeters deep from the plant 18 to 20 centimeters is to be opened, and the pre-rotated, finely-ground organic fertilizer is sprinkled into the ditch, and the 1200-mu per mu. 1500 kilograms or plump organic bio-fertilizer 500 kilograms, if the organic fertilizer is insufficient or the quality is not high, you can also add 15 kg of ammonium carbonate or ammonium sulfate and other fast-acting fertilizers, then buried the ditch. Decomposed fecal urine can also be applied from 1500 to 2000 kilograms. Or per acre more than 5 kg diluted root 200 ~ 500 times to root or with watering, can promote the heart, increase the weight of the white menu, reduce the incidence of disease. Chinese cabbage enters the ball-bearing period. Both the ground and the underground are in a period of vigorous growth. The demand for fertilizer and water reaches a peak. This period to re-fertilize, per acre can be followed by ammonium carbonate or ammonium sulfate 25 to 30 kilograms or 2500 kilograms of human waste, generally taken into the fields along the water. Be sure to pay attention to uniformity when fertilizing. In autumn, there is often continuous rain or heavy rain. Pay attention to drainage work.
