Scientific prevention and control of snails in vegetable fields

Pay attention to the following two points:

First, choose the correct fertilizer. You can use pure biological bacteria once or twice or fertilizers with the function of mulching and nourishing roots, such as chitin, seaweed essence, silicon, etc. Although such fertilizers are also beneficial to rooting, they will not strongly interfere with the differentiation and growth of the root system like hormones. More capillary roots appear.

The second is to promote the expansion of main roots and lateral roots through correct management measures. Appropriate phosphorus, calcium, zinc and other elements can meet the rapid growth of root tips and accelerate the growth of main roots and lateral roots; proper water control can attract roots to grow into deep soil with sufficient moisture; hoeing can cut off roots floating in shallow soil, These roots are easily affected by the environment and lose their absorptive capacity, so they cannot be used as the main absorptive area; late covering of mulch is mainly to avoid affecting the growth of main roots and lateral roots because the shallow soil environment is suitable for promoting the growth of surface capillary roots.
