What are the reasons for the cracking of cabbage?

1. If the water supply is insufficient in the early stage and too much in the later stage, it will cause the leaf ball to crack.

two。 Continue topdressing in the middle and later stage of heading, that is, after topdressing too late, the inner bulb continues to grow, and the size of the outer bulb has been fixed, which will also cause the bulb to crack under the internal bulb expansion pressure.

3. If the leaf ball is mature and does not appear on the market in time, it will also cause cracking.

4. Chinese cabbage which is transported or stored for a long distance can only be harvested when it is ripe. If overmature Chinese cabbage is harvested, the leaf ball will crack in the process of transportation or storage.

What if there is a crack in planting Chinese cabbage?

1. If the water supply is insufficient in the early stage and too much in the later stage, it will cause the leaf ball to crack.

two。 Continue to topdressing in the middle and later stage of heading, that is, the inner bulb continues to grow too late, and the size of the outer bulb has been fixed, which will also cause the bulb to crack under the internal bulb expansion pressure.

3. If the leaf ball has matured and fails to appear on the market in time, it will also cause cracking.

4. Chinese cabbage which is transported or stored for a long distance can only be harvested when it is ripe. If the harvest is too mature, the leaf ball will crack in the process of transportation or storage. Cracked leaf bulbs can also cause soft rot or other diseases and insect infections. Therefore, attention should be paid to uniform water supply in cultivation, topdressing should be stopped in the later stage, and root cutting can be done in situ if it can not be listed, so as to prevent the root system from continuing to absorb water and nutrients.
