Zinc-containing compound fertilizer for wheat

Abstract

The invention discloses zinc-containing compound fertilizer for wheat. The zinc-containing compound fertilizer is prepared from raw materials in parts by weight as follows: 25-27 parts of zinc nitrate, 16-18 parts of smithsonite, 28-30 parts of urea, 13-15 parts of ammoniated superphosphate, 24-26 parts of potassium chloride, 20-22 parts of soybean straw, 5-7 parts of vermiculite, 3-5 parts of cycad leaves, 8-10 parts of bark of a white bark pine, 5-7 parts of calocedrus macrolepis leaves, 12-14 parts of bark of Cryptomeria fortune, 6-8 parts of cottonseed cakes and 0.45-0.5 parts of compound microorganisms. The formula is scientific and reasonable, effective nutritional ingredients of the raw materials are mutually integrated and supplement one another, tillering of the wheat can be promoted, robust growth of wheat plants is promoted, the aphid damage rate of the wheat is reduced, absorption and conversion of zinc elements can be effectively promoted, the withering rate of wheat seedlings can be effectively reduced, the thousand kernel weight and the yield of the wheat are increased, and more economic benefits are brought to a grower.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, in particular to a zinc-containing wheat compound fertilizer. Background technique [0002] Currently, the main nutrients in compound fertilizers are nitrogen, phosphorus, and potassium, but crop growth requires 18 essential nutrients. Therefore, the nutrients contained in conventional fertilizers cannot fully meet the needs of crop growth. In current crop production, zinc deficiency in wheat is relatively common. Zinc mainly promotes cell division and reproductive growth. Zinc deficiency often leads to a decrease in thousand-grain weight of wheat, shortening of internodes, small clusters of leaves, shrunken leaf margins, and chlorosis between veins. White, showing yellow, white and green stripes, with patches of white seedlings and yellowed seedlings. In severe cases, stiff seedlings and dead seedlings appear, and the earing is late, and the ears are small and the grains are small, whic...

Problems solved by technology

[0002] The main nutrients in the current compound fertilizers are nitrogen, phosphorus, and potassium, but crops need 18 essential nutrients for growth. Therefore, the nutrients contained in conventional chemical fertilizers cannot fully meet the needs of crop growth.

In current crop production, zinc deficiency in wheat is relatively common. Zinc mainly promotes cell division and reproductive growth. Zinc deficiency often leads to a decrease in thousand-grain weight of wheat, shortening of internodes, small clusters of leaves, shrunken leaf margins, and chlorosis between veins. White, showing yellow, white and green stripes, with patches of white seedlings and yellowed seedlings. In severe cases, stiff seedlings and dead seedlings appear, and the earing is late, and the ears are small and the grains are small, which seriously affects the healthy growth of wheat plants and the yield of wheat.
