What is the role of zinc in plant growth?

What is the role of zinc in plant growth? Zinc is an indispensable trace element for crop growth. Zinc deficiency causes plant dwarf, short internodes, leaf expansion and elongation are inhibited, leaflets appear, and leaf margins are distorted and wrinkled. . Corn whitening seedlings, rice dead seedlings, etc. are all caused by zinc deficiency.

In order to supplement the zinc element in the process of rice growth, it is necessary to promptly lick after fertilization, and close the field water to prevent the outflow of fertilizer and water. Dry land is generally applied to dry manure and water manure. The top dressing is 50-100 grams of zinc sulfate per acre, dissolved in water and then mixed with 50 kg of water, and sprayed at 4 o'clock in the afternoon.

Zinc has a relatively large role in plant growth. Spraying foliar fertilizer is also a more effective way to supplement zinc in plants. The concentration of sprayed zinc fertilizer and the amount of spray can be increased or decreased depending on the size of the plant. In spraying, if the concentration is too large to damage the leaves, it is best to add 0.2% slaked lime to adjust the pH of the solution. Generally, it is sprayed once in the seedling stage, jointing stage and flowering stage of the crop. The application of zinc fertilizer should vary from place to place, depending on the crop, and should not be applied blindly.
