1. Insufficient root fertilization When the roots are infertile, such as in the late stage of crop growth, the root activity declines and the ability to absorb fertilizer decreases; or when the soil environment is unfavorable to crop growth, such as excessive water, drought, soil peracid Over-alkali, causing the root absorption of crops to be hindered, and crops need to resume growth quickly. If the root application method can not meet the crop needs in time, only foliar application can be used to quickly supplement nutrients and meet the needs of crop growth and development.
2. Rapid supplementation of nutrients In the process of crop growth, crops have shown certain nutrient deficiencies. Because of the time required for soil fertilization, nutrients can be absorbed by crops, and the symptoms of crop deficiency cannot be alleviated in time. At this time, using foliar fertilization, nutrients can quickly enter the plant through the leaves, solving the problem of deficiency.
3. Give full play to the fertilizer effect Some fertilizers such as phosphorus, iron, manganese, copper, zinc fertilizer, etc., if applied as roots, are easily fixed by the soil, affecting the application effect, and foliar spraying is not limited by soil conditions. For example, some fruit trees and other deep root crops absorb less nutrients. If traditional fertilization methods are difficult to apply to the root absorption site, they can not fully exert their fertilizer efficiency, while foliar spray can achieve better results. effect.
4. Economical cost All kinds of trace elements are essential nutrients in the process of crop growth and development, but the application amount is very small, such as molybdenum fertilizer, the application amount per acre is only tens of grams, if it is not easy to apply evenly by root application method. Only by foliar application can it be cost effective. According to research estimates, the general crop sprays boron fertilizer on the foliar surface, and the utilization rate of boron is 8.18 times that of the base application. From the perspective of economic efficiency, foliar application is more cost-effective than root application.
5. Reducing pollution to the soil A large amount of nitrogen fertilizer is applied to the soil, which easily causes the accumulation of nitrate in groundwater and vegetables, which is harmful to human health. About 75% of the nitrates absorbed by humans come from vegetables. If foliar fertilization is adopted, proper reduction of soil fertilization can reduce nitrate content in plants and residual mineral nitrogen in soil. On salinized soils, soil fertilization may increase the concentration of soil solution and increase the salinization of the soil. The use of foliar fertilization measures not only saves the amount of fertilization, but also reduces the pollution of soil and water sources. It is an effective fertilization technique with two advantages.
