Four key points of vegetable Management in Winter

With the development of greenhouse vegetables, especially in winter, vegetable management should be paid more attention to. Management is the key. Vegetable farmers should be reminded to master the following four points:

1. Scientific fertilizer control. Seeing the slow growth of vegetables, I thought it was caused by the lack of fertilizer, and began to apply too much fertilization. in fact, the more fertilizer applied, the more it would affect the root system of vegetables, which was not fundamentally solved. Therefore, if there is a shortage of water in this period, it can be watered to control the use of chemical fertilizers.

2. Promote root rejuvenation. If the crop growth has been weak, the effect of supplementary fertilizer is not good, and the root system can not absorb it. Irrigating roots with roots can promote the infinite development of plant roots and promote matching transport for the navigation of plant nutrient elements; at the same time, the supplement of boron fertilizer can promote the elongation of capillary roots and zinc fertilizer can improve the stress resistance of vegetables.

3. Control the soil. Only by creating a safe and favorable root environment can we ensure the growth of the root system and make the root system go deeper. Through physical, biological and agricultural measures and other means to loosen the soil, change the soil into aggregate structure, and promote rooting.

4. Foliar spraying fertilizer. Foliar spraying of new high-fat film and photosynthetic nutrient film fertilizer can help plants absorb a large amount of light fertilizer, light energy, light, compatible conventional fertilizers and nutrients to the limit of plant growth and development. One application is beneficial for the whole year.
