First, the small water is poured, not to root and fat.
Second, alleviate salt damage, solve the problem that the concentration of soil solution is too high, resulting in less roots and poor rooting.
Salt damage is not formed overnight, and the solution to salt damage cannot be done overnight. For the sheds where the surface of the soil has clearly shown the phenomenon of “moss, red frost, hoarfrostâ€, it is recommended that the vegetable farmers start from bit by bit and rationally fertilize. Base fertilizer, increase the application of straw fertilizer and biological fertilizer; topdressing, reduce the amount of chemical fertilizer, can use full water-soluble quick-acting fertilizer (instead of ordinary compound fertilizer, increase the application of biological bacteria and fertilizer).
Third, deep turn the soil, break the bottom of the plow, avoid the problem of roots, roots and other roots.
In production, the current vegetable growers are increasingly dependent on machinery, and rotary tillers are used to turn the ground. The rotary tiller is only 13-15 cm deep, and the base fertilizer is mostly concentrated in the soil layer after the grounding, which is easy to cause the seedlings to burn. What is more serious is that the rotary cultivator is used for several years, and it is easy to form the plough bottom layer under 13-15 cm, which is not only unfavorable for deep rooting of the root system, but also easy to cause premature aging of vegetables, and it is also easy to accumulate water and accumulate fertilizer and cause root injury. In recent years, the frequent occurrence of yellow leaves in the middle of vegetable growth has been caused by this, especially in the winter and spring low temperature seasons. After using the rotary tiller to break the base fertilizer and evenly mix it into the shallow layer of the soil, it is better to use the hoe to turn it over again. The bottom layer of the plough is broken, and the depth is 25-30 cm.
Fourth, the soil disinfection, reduce or eliminate the number of pathogenic bacteria in the soil; with the colonization of the application of pesticides to protect the root system, reduce the probability of pathogens infecting the root system.
