2. Fast-absorbing foliar fertilizer Due to direct spraying on the foliage of crops, various nutrients can directly enter the plants from the leaves, directly participate in the metabolism of the crops and the synthesis of organic substances, and its speed and effect are better than those of soil fertilization. fast.
3. Good effect In the dry matter forming crop yield, 90-95% of dry matter comes from the product of photosynthesis. After the crop is applied to foliar fertilizer, the leaves absorb a large amount of nutrients, promote various physiological processes of the crop body, and significantly improve The intensity of photosynthesis can effectively promote the accumulation of organic substances in crops, increase the fruit setting rate and seed setting rate, increase yield, and improve quality.
4. The amount of leaf foliar fertilizer is not sprayed directly on the soil because it is sprayed on the surface of the leaf, thus avoiding the fixation, failure or leaching loss of nutrients in the soil. Foliar spraying is usually used in a very small amount and at a very low concentration. The amount is only one-tenth to one-fifth of the soil fertilization. When the nutrients are absorbed, they are directly transported to the most vigorously grown parts of the crop. The nutrient utilization is high. .
Four advantages of foliar fertilizer
1, targeted fertilizer according to soil Fertility status, level of soil for fertilizer and crop requirements for nutrients to determine the type and formulation of nutrients, crop replenish the lack of nutrients, reduce or eliminate the deficiency symptoms of crops .
