The use of foliar fertilizer must first clarify the leaf structure of the plant. It cannot replace soil fertilization, but it can supplement the nutrients absorbed by the plant. It is a fertilization technology with fast fertilizer effect, high fertilizer utilization rate and low dosage. .

Introduction to foliar fertilizers

Foliar fertilizers refer to fertilizers that apply nutrients required by crops directly to the leaves to make up for the lack of nutrient absorption by plant roots.

Characteristics of foliar fertilizer

Advantages

First, the absorption of foliar fertilizer is fast. Various nutrients enter the plant body directly from the leaves and can be quickly absorbed by the plant;

Second, the effect of foliar fertilizer is strong. Foliar fertilizer is easily absorbed by plants, which can quickly alleviate the fertilizer deficiency of crops, promote the progress of various physiological processes in plants, and improve the quality of plants;

Third, the amount of foliar fertilizer is small and the cost is Low. Foliar fertilizer is sprayed directly on the leaves, which is more economical than root fertilizer.

Disadvantages

First, the horniness is relatively high Thick leaves have a low nutrient penetration rate and a small amount of absorption;

Secondly, foliar fertilizers tend to drip from the leaves, and the sprayed nutrients are easily lost by rain;

Third, the spray liquid dries quickly on the leaf surface, affecting the absorption of plants;

Fourth, nutrients such as calcium are difficult to transfer from the absorption part to other parts;

Fifth, the nutrients provided by foliar fertilizers cannot meet all the needs of plant growth;

Sixth, improper use of foliar fertilizers can easily cause plant leaf burns;

Seventh, the effective time of foliar fertilizers It is short and requires multiple sprayings, which is time-consuming and labor-intensive.

Precautions for using foliar fertilizer

Foliar fertilizer should be based on root fertilization, and the appropriate spray concentration, spray method, spray time, and spray time should be selected. Only in this way can the effect of foliar fertilizer be fully exerted.
