At present, fertilizers such as urea, potassium dihydrogen phosphate and potassium chloride are used in the production of foliar spray fertilizers. Due to the different types of vegetables and cultivation methods, the concentrations used are also different. For example, when the growth of vegetables in greenhouses or greenhouses is weak, the concentration of sprayed urea should be lower, generally 0.3%, and when adult plants are used, the concentration can be increased to 0.5 to 1%. When the radish, cabbage, cabbage are used in the adult period, the concentration can be increased to 1 - 1.5%. In order to increase the disease resistance of the plants and improve the quality, they can also be mixed and sprayed with 0.5-1% potassium dihydrogen phosphate. The effect is better.
Generally, when the wind is sunny and the temperature is high, the foliar fertilizer is sprayed and the crop absorbs faster. The young leaf absorbs faster than the old leaf, and the leaf surface absorbs more than the leaf back surface. In order to increase the effect of spraying fertilizer, some detergents, such as washing powder, should be properly added, so that the medicine can be uniformly attached to the foliage. In order to save manpower, foliar spray fertilizer can also be sprayed with pesticides. However, when spraying fertilizers, attention should be paid to grasping appropriate concentrations. When the fertilizers are sprayed excessively, it is easy to cause damage on the leaves, and the leaves turn green and dry.
The various nutrients needed for vegetables are basically absorbed from the soil through the root system. However, many vegetables can also absorb nutrients from the leaves. Therefore, foliar spray is often used in production when necessary. For example, when the roots are damaged due to transplantation or other reasons, the crops will not be able to absorb nutrients from the roots at one time, and can be used to make up for them by spraying fertilizers. Another situation is that, due to lack of soil fertility, when the vegetable lacks a certain element, the spray fertilizer method can make the crop be replenished sooner. In addition, in the case of foliar fertilizer application in combination with root absorption, it may have an effect of promoting production, improving quality, and increasing disease resistance.
