Please introduce the method of spraying the aqueous solution of nutrients needed by plants on the leaves so that the plants can absorb effective nutrients directly through the leaves. This technique is called foliar fertilization for vegetables. Compared with soil fertilization, this technique has the advantages of faster transformation, higher fertilizer use efficiency and enhanced nutrient absorption by roots. Foliar fertilizer can be divided into a large number of element fertilizers, micro-fertilizers, organic fertilizers, microbial fertilizers, or foliar fertilizers of photosynthesis enhancers or pesticides, and so on.

For example, for cucumber, eggplant, pepper, celery, leek, and other vegetables in the greenhouse, we can choose the solid multi-element compound foliar fertilizer "Gaole" which has obvious yield-increasing effect with the addition of disease prevention and treatment drugs, and can spray 0 on the greenhouse cucumber in the fruit period. 2% urea plus 0. The sugar and nitrogen solution of 2% potassium dihydrogen phosphate and 1% sucrose can not only increase disease resistance, but also reduce the damage of downy mildew; light and micro-fertilizer and light absorption inhibitors are applied to spray tomato, cucumber, pepper, cloud bean, celery, cabbage, cabbage, lettuce, cauliflower and so on.
