With the development of greenhouse vegetable, especially the management of vegetables in winter, we must pay more attention to it. Management is the key to remind farmers to grasp the following four points: 1, scientific control of fertilizer. Seeing the phenomenon of slow growth of vegetables, it was thought that it was caused by insufficient fertilizer and excessive fertilization was started. In fact, the more fertilized, the more it would affect the roots of vegetable roots, and did not fundamentally solve it. Therefore, if water shortage can be watered during this period, use of chemical fertilizers should be controlled. 2, root to rejuvenate. If the growth of the crop is already weak, the supplement fertilizer will not work well and the root system will not absorb it. Root can be used to root irrigation, can promote the infinite development of plant roots, can promote the navigation of plant nutrients to promote the matching transport; while supplementing boron fertilizer to promote capillary root elongation, supplement of zinc fertilizer to improve the resistance of vegetables. 3, control the soil. Only by creating a safe and favorable root environment can the growth of the root system be guaranteed and the root system can be deeper. By means of physical, biological and agricultural comprehensive measures, the soil is loosened, the soil is changed into a granule structure, and rooting is promoted. 4, foliar spray fertilizer. Foliar application of new high fat film and photosynthetic film fertilizer can help plants absorb a lot of light, light energy, light, compatible with conventional fertilizers, nutrients supply plant growth and development to the limit. Apply once a year to benefit. Jiangsu Tiankang Food Co., Ltd. , https://www.tiankangfood.com
