Nutrient fertilizer applied to ear-up stage of cotton and preparation method of nutrient fertilizer

Abstract

The invention provides special compound fertilizer applied to the seedling raising period of fine staple cotton. The special compound fertilizer is prepared from raw materials in parts by weight as follows: 40-50 parts of farmyard manure, 15-17 parts of calcium phosphate, 32-34 parts of ferric sulfate, 5-7 parts of phosphoric acid, 6-8 parts of gelatin, 2-4 parts of calcium borate and 1-3 parts of a synergist. The special compound fertilizer has the beneficial effects as follows: organic fertilizer and inorganic fertilizer are collocated scientifically, balanced nutrition is realized, absorption by crops is facilitated, the fertilizer is non-toxic and pollution-free, health of the crops is guaranteed, the prepared fertilizer has high nutrient content and high fertilizer efficiency in actual application, cotton quality is effectively improved, and cotton growth is promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizer preparation, in particular to a cotton budding stage nutrient fertilizer and a preparation method thereof. Background technique [0002] Cotton, shrubby plant, 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 cotton bolls, and the fluff on the cottonseeds grows from the skin of the cottonseeds and fills the inside of the cotton bolls. When the cotton bolls mature, they crack, exposing soft fibers. The fibers are white or white with yellow, about 2 to 4 cm long, containing about 87 to 90% cellulose. The countries with the highest cotton production include China, the United States, India, etc. The value of cotton is very wide, but in actual planting, the demand for fertilizers is relatively strict, especially w...

Problems solved by technology

The countries with the highest cotton production include China, the United States, India, etc. The value of cotton is very wide, but in actual planting, the demand for fertilizers is relatively strict, especially when budding, the requirements for fertilizer efficiency are more stringent, and the selection of fertilizers If it does not meet the specifications, it will directly affect the quality of cotton and the output of cotton
