Vegetable rotation has principled rational planting efficiency
Vegetable rotation is an effective measure to combat heavy mites, rational use of soil fertility, reduce pests and diseases, and improve planting efficiency. When arranging vegetable rotations, it is necessary to remember and master the following principles:
One is to rotate the vegetables of different families. The same pests and diseases occur in the same vegetables, and the rotation of different vegetables can cause the bacteria to lose their host or change the living environment, so as to reduce or eliminate pests and diseases.
The second is to rotate vegetables that absorb different soil nutrients and different root depths. According to the degree of soil nutrients absorbed by vegetables and the different depths of roots, soil nutrients can be fully utilized.
The third is to pay attention to the effects of various vegetables on soil pH and soil fertility. For example, planting cabbage, potatoes, etc. will increase soil acidity, while planting corn, pumpkin, etc. will reduce soil acidity; onions that are more sensitive to acidity, as corn, pumpkin, and later crops, can obtain higher yield.
The fourth is to consider the inhibition of weeds by the former crops. Some vegetables with long growth period and large leaf area coverage on soil area have inhibitory effects on weed growth; while some types of vegetables are easy to breed weeds due to slow growth at seedling stage or small leaves, so when cultivated The former should be arranged to rotate with the latter.
