Four key points for winter vegetable management that growers must master

With the development of greenhouse vegetable production, especially winter vegetable management, more attention must be paid. Management is the key. Vegetable growers are reminded to master the following four points:

1. Scientific fertilizer control. When seeing vegetables grow slowly, growers assume it is caused by insufficient fertilizer and begin to over-apply fertilizer. In fact, the more fertilizer is applied, the more it affects the downward growth of vegetable roots, without solving the problem at its root. Therefore, at this stage, if there is a water shortage, water can be applied, and the use of chemical fertilizers should be controlled.

2. Promote roots and restore vigor. If the crop has already become weak, supplementing fertilizer at this time has a poor effect because the roots cannot absorb it. Root irrigation with Genshitong can promote the unlimited development of plant roots, guide plant nutrient elements, and promote matching delivery; at the same time, supplementing boron fertilizer promotes the elongation of fine roots, and supplementing zinc fertilizer improves the stress resistance of vegetables.

3. Control the soil. Only by creating a safe and favorable root environment can root growth be ensured, allowing roots to penetrate deeper. Through physical, biological and comprehensive agricultural measures, loosen the soil, change the soil into a granular structure, and promote rooting.

4. Foliar spraying. Foliar spraying of Xingao Zhimo and photosynthetic nutrient film fertilizer can help plants absorb large amounts of light fertilizer, light energy and light, is compatible with conventional fertilizers, and supplies nutrients for plant growth and development to the limit. One application benefits the whole year.
