Special fertilizer for cotton

Abstract

The invention relates to a compound fertilizer for agricultural production, particularly a special fertilizer for cotton. The invention is characterized in that the special fertilizer for cotton is prepared by proportionally mixing rotten chicken manure, ammonium chloride, diammonium phosphate, potassium chloride, borax and ammonium molybdate. The special fertilizer comprises the following raw materials in percentage by weight: 67-70% of rotten chicken manure, 5-10% of ammonium chloride, 9-17% of diammonium phosphate, 7-13% of potassium chloride, 1% of borax and 0.04% of ammonium molybdate. The total nutrient content of the special fertilizer is 16%, wherein the content of nitrogen is 4%, the content of phosphoric anhydride is 4-8%, and the content of potassium oxide is 4-8%; and besides, the content of borax is 1%, the content of ammonium molybdate is 0.04%, and the content of organic substance is 20%. The special fertilizer for cotton can satisfy the demands of cotton growth and development for several main nutrient elements, and has the effects of strongly activating soil, removing hardening, increasing fertility, retaining water to resist drought and improving continuous cropping; and the special fertilizer for cotton can effectively prevent and treat the symptoms of budding without flowering and flowering without fruiting of cotton as well as the symptom of hard blooms, increase both yield and income, and improve the quality.

Description

technical field [0001] The invention relates to a compound fertilizer for agricultural production, in particular to a special fertilizer for cotton. Background technique [0002] As one of the main economic crops, cotton is planted in a wide range in my country, and the production of cotton is closely related to people's daily life. Therefore, increasing cotton production and improving cotton quality is of great significance to the development of my country's light textile industry and the improvement of people's living standards. [0003] Cotton yield and quality are closely related to comprehensive factors such as cotton variety, soil, climate, moisture, fertilization, and pest control. Among the factors, fertilization plays a very important role in cotton yield and quality. effect. This is because fertilizer is the material basis for increasing cotton production and improving quality, and applying fertilizer is an important technical measure to greatly increase cotton p...

Problems solved by technology

[0010] According to the survey and statistics of relevant departments, the current structure of fertilization of cotton crops in the Huaibei Plain is very unreasonable, manifested in the fact that the amount of organic fertilizer is almost blank, the amount of nitrogen is seriously excessive, the amount of phosphorus is insufficient, and the amount of potassium is seriously depleted. The average ratio is 1:0.22:0.35, and there is a considerable area of ​​boron and molybdenum deficiency
