How to Manage Chinese Cabbages

Chinese cabbage cabbage is the peak period of Chinese cabbage leaf weight growth. Good management of water and fertilizer is the key to making the autumn cabbage cabbage core.

Keeping the moisture content of Chinese cabbage into the core period ensures that the soil has sufficient moisture to prevent the surface from cracking. The water consumption of Chinese cabbage entering the filling period is greater than that of the previous period. It must be supplemented by irrigation to keep the water even and sufficient supply. In particular, the moisture content of leaves in Chinese cabbage accounts for 95%-96%, so it is particularly crucial to strengthen water management during the core period. The specific requirements are: the first water should be small during the filling period, and the growth of plants will be harmed when the water volume exceeds the general level; the first water will enter the normal irrigation after 4-5 days, and the water will generally be 5-7 days, and the amount of water will not be less than 30 per time. Square; stop watering the first week before chopping vegetables, one of which is to avoid too much water intolerant storage; the second is to facilitate harvesting and reduce the damage caused by mechanical damage.

In order to reduce the mechanical damage caused by manual operation, the topdressing fertilizer is to be applied in a timely manner. The topdressing phase of the dressing should be mainly followed by water and fertilization. The first topdressing is applied before the cold dew, and the second time is followed by a top dressing several days before the frost fall. During this period, the temperature gradually decreased, and nitrogen fertilizers should be used as the topdressing fertilizer. Generally, ammonium sulfate is used. It is advisable to apply 20-30 kg per mu, followed by irrigation with water. The amount of top-dressing should be increased appropriately for lands with a slightly lower degree of baggage. In the later period, it is necessary to stop top dressing so as not to make the cabbage grow long.
