High-protein organic fertilizer for saline-alkali land

Abstract

The invention discloses a high-protein organic fertilizer for a saline-alkali land, and belongs to the technical field of saline-alkali land improvement and efficient fertilization. The high-protein organic fertilizer comprises the following components in parts by weight: 35-42 parts of manure, 30-35 parts of ammonium sulfate, 30-35 parts of ammonium nitrate, 26-32 parts of rice hulls, 20-30 partsof furfural residue, 18-24 parts of sludge manure and 8-16 parts of sulfur, wherein the ammonium sulfate and the ammonium nitrate are acidic nitrogen fertilizers, and neutralize alkali while nitrogenis provided for soil; the sulfur is applied to the soil as a sulfur fertilizer, and participates in synthesis of protein in a plant besides the efficacy of reducing soil alkalinity; an enzyme produced during the synthesis can increase the nitrogen metabolizing capability of the plant, so that the synthesis and accumulation of the protein are promoted and the plant yield is increased.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement and high-efficiency fertilization, and specifically relates to a high-protein organic fertilizer for saline-alkali land. Background technique [0002] Protein is one of the basic substances that make up plant cells. During the growth of plants, some stem and leaf cells continuously synthesize protein to meet the needs of building new cell tissues and organs. The main components of protein are carbon, hydrogen, oxygen and nitrogen. It can be seen that without nitrogen, protein cannot be synthesized. Plants can obtain the three elements of carbon, hydrogen and oxygen in the air, and nitrogen mainly needs to be obtained in the soil. There are many saline-alkali lands in Northwest, Northeast, North China and coastal areas of China. Under the action of evaporation, the land in arid areas evaporates water into water vapor and discharges it into the air, but the salt in the water c...

[0002] Protein is one of the basic substances that make up plant cells. During the growth of plants, some stem and leaf cells continuously synthesize protein to meet the needs of building new cell tissues and organs. The main components of protein are carbon, hydrogen, oxygen and nitrogen. It can be seen that without nitrogen, protein cannot be synthesized. Plants can obtain the three elements of carbon, hydrogen and oxygen in the air, and nitrogen mainly needs to be obtained in the soil. There are many saline-alkali lands in Northwest, Northeast, North China and coastal areas of China. Under the action of evaporation, the land in arid areas evaporates water into water vapor and discharges it into the air, but the salt in the water cannot be eliminated and remains in the soil. After a long period of accumulation, the salt in the soil gradually increases, so And the formation of saline-alkali land, because the salt content of the saline-alkali soil itself is too high, according to the principle of plant cell osmosis, it is difficult for plant cells to absorb inorganic nutrients such as nitrogen, resulting in the plant itself being unable to synthesize protein and stunted, and the existing special fertilizer for saline-alkali land has low fertilizer efficiency , the effect of supplementing nitrogen needed by plants in saline-alkali soil is not good, which affects the synthesis and accumulation of protein in plants and affects plant growth
