Chinese cabbage is applied with biogas fertilizer. Cabbage not only grows fast, yields high, matures early, and has good quality, but also has obvious disease prevention effects.
1. Chinese cabbage seedlings. Use 40% biogas slurry for acupoint application, or apply 800 kg of biogas slurry per acre along the ridge, but watering must be done immediately after pouring to avoid burning seedlings.
2. The rosette is poured. This period is one of the periods in which the incidence of Chinese cabbage is high. Except that the biogas slurry is applied to the Qingshui point or the ridge is applied, if the foliar spray is applied with 30% biogas slurry, the effect is better.
3. Casting during the balling period. In this period, the amount of biogas slurry can be increased to 1000 kg per mu, and it can be applied in combination with watering for 3 times.
4. Casting at maturity. After the Chinese cabbage enters the maturity stage, it is not sensitive to the fertilizer water, so the application rate of the biogas slurry can be reduced to about 400 kg per mu, which is also applied in combination with the watering.
