The method of applying fertilizer solution to the plant to obtain nutrient elements through the leaves is called foliar fertilization. For the purpose of foliar absorption, the nutrient required by the crop is directly applied to the foliar fertilizer, which is called foliar fertilizer.
Why use foliar fertilizer
1. Insufficient supplementation of root fertilization When crop root infertility is inconvenient, for example, in the late growth stage, the root activity declines and the ability to attract fertilizers decreases; or when the soil environment is unfavorable for crop growth, such as excessive moisture, drought, and soil acidification. Over-alkali causes the absorption of crop roots to be impeded, and crops need to resume growth quickly. If the method of root application cannot meet the needs of crops in a timely manner, only the foliar spray can be used to rapidly supplement the nutrients and meet the needs of crop growth and development.
2. Quickly replenish nutrients In the process of crop growth, the crops already show some nutrient deficiency, and the use of soil fertilization requires a certain amount of time for nutrients to be absorbed by the crops and cannot alleviate the symptoms of crop nutrient deficiency in time. When foliar fertilization is used at this time, the nutrients can quickly enter the plant through the leaves to solve the problem of nutrient deficiency.
3, give full play to the fertilizer effect of certain fertilizers such as phosphorus, iron, manganese, copper, zinc and other fertilizers, if done as a root, easily fixed by the soil, affecting the application effect, and the use of foliar spray will not be limited by soil conditions.
Foliar fertilizer application is small, the effect is rapid and obvious, improving the utilization of fertilizer. It is an economical, effective and good fertilization measure, especially for some trace elements that are more unique in their foliar application. However, we should also see that the foliar fertilization work is more troublesome, the labor cost is also more, and at the same time vulnerable to climatic conditions, but also because of different crop types and growth periods, the effect of foliar fertilization is quite different. Therefore, we must apply the foliar fertilization technique correctly on the basis of root fertilization in order to give full play to the role of foliar fertilizer in increasing production and increasing income.
