Problems solved by technology

[0004] At present, cotton is mainly used to prevent pests and diseases by mixing and stirring chemical reagents and toxic pesticides, applying them to the soil or crops, and using them year after year, resulting in drug resistance of pests and diseases, soil compaction, and pollution of water sources, soil and crops. The quality of agricultural products has declined, and pesticide residues exceeding the standard have seriously affected people's physical and mental health and the competitiveness of my country's cotton in the international market

preparation example Construction

[0035] Specifically, the preparation method of the base fertilizer comprises the steps of:

[0036] After drying nitrogen, phosphorus and potassium compound fertilizer, medium and trace elements, sepiolite, quicklime, and attapulgite, they are uniformly mixed, crushed, and passed through a sieve of 80 to 100 meshes to obtain a spare material 1;

[0037] After pulverizing the organic fertilizer, pass it through a 80-100 mesh sieve to obtain the spare material 2;

[0038] The standby material 1 and the standby material 2 are uniformly mixed in a mixer, heated to 60-70° C., dried and sent to a granulator for granulation to obtain a base fertilizer.

[0039] Further, the first topdressing fertilizer includes the following components in parts by mass: 170-180 parts of urea, 145-155 parts of diamine phosphate, 146-152 parts of potassium chloride, 1.5-1.8 parts of ferrous sulfate, sulfuric acid Zinc 1.2-1.6 parts, EDTA chelated manganese 1.2-1.6 parts, borax 1.4-1.8 parts, ammonium ...

Abstract

The invention relates to a special fertilizer for cotton. The special fertilizer comprises a base fertilizer, a primary topdressing fertilizer and a second topdressing fertilizer, wherein the mass ratio of the base fertilizer to the primary topdressing fertilizer to the second topdressing fertilizer is (100 to 120):(60 to 80):(8 to 12). The special fertilizer for cotton has the advantages that according to growth features of cotton, different fertilizers are applied in different periods; the vain growth of cotton seedlings and nutrient loss in the early stage, and fertilizer lack and plant premature senility in the back stage can be avoided, so that the yield and the quality of the cotton are obviously improved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for cotton. Background technique [0002] Cotton is the seed fiber of the Malvaceae cotton plant, native to the subtropical zone. The plant is shrubby and can grow up to 6 meters high in tropical areas, generally 1 to 2 meters. The flowers are milky white, turn dark red shortly after flowering and then wither, leaving small green capsules called cotton bolls. There are cottonseeds in the bolls, and the fluff on the cottonseeds grows from the skin of the cottonseeds and fills the inside of the cotton bolls. When the bolls mature, they split open, exposing the soft fibers. The fibers are white to white with yellow, about 2 to 4 cm long, containing about 87-90% cellulose. [0003] Cotton needs a variety of nutrients during the growth process. Since the nutrients in the soil are limited, these nutrients need to be supplemented in a timely and...
