With the development of greenhouse vegetables, especially the management of vegetables in winter, more attention must be paid to management. The management is the key, reminding vegetable farmers to master the following four points:
1. Scientific fertilizer control. Seeing the slow growth of vegetables, I thought it was caused by insufficient fertilizer, and began to over-fertilize. In fact, the more fertilization, the more the root system of vegetables would be affected, which was not fundamentally resolved. Therefore, if there is water shortage in this period, watering can be used to control the use of chemical fertilizers.
2. Promote root recovery. If the crop growth is already weak, fertilizer supplementation is not effective at this time, and the root system cannot absorb it. The root can be irrigated with roots, which can promote the unlimited development of the plant root system, which can promote the matching and transportation of plant nutrients; meanwhile, boron fertilizer can be used to promote the elongation of capillary roots, and zinc fertilizer can be used to improve the resistance of vegetables.
3. Control the soil. Only by creating a safe and favorable root environment can the root system be guaranteed to grow and make the root system deeper. Through physical, biological and agricultural comprehensive measures, loosen the soil, change the soil into agglomerate structure, and promote rooting.
4. Foliar spraying. Foliar spraying of new high-fat film and photosynthetic nutrition film fertilizer can help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers, and nourishment for plant growth and development to the limit. One application benefits throughout the year.
