Abstract

The invention relates to a special biological slow-release compound fertilizer for cotton and a preparation method thereof. The special biological slow-release compound fertilizer for cotton is prepared from the following raw materials: 280-310 parts of urea, 300-350 parts of potassium chloride, 150-200 parts of monoammonium phosphate, 70-120 parts of biological humic acid, 10-15 parts of chelation medium and trace elements, 30-50 parts of double superphosphate, 4-10 parts of sodium borate, 15-75 parts of nano carbon and 0.2-0.5 part of an auxiliary slow-release agent which is polyvinyl alcohol or urea formaldehyde and is selectively used according to different areas. The invention also relates to a preparation method of the compound fertilizer. The special biological slow-release compound fertilizer for the cotton is complete in nutrients; nitrogen and potassium nutrients have slow-release properties; the compound fertilizer can conform to the nutrient absorption law of the cotton, has effects of promoting and regulating growth of the cotton, and is capable of improving cotton yield and fiber quality and effectively reducing occurrence rates of cotton premature senescence and greensickness; the cotton planting benefit is increased; meanwhile, the utilization rate of the slow-release fertilizer is increased.

Description

technical field

[0001] The invention relates to the field of fertilizers, in particular to a special biological slow-release fertilizer for high tower melt granulated cotton and a production method thereof, belonging to the field of special compound fertilizers. Background technique

[0002] As a traditional thermal insulation material, cotton is natural and soft, non-irritating to the skin, natural and environmentally friendly, has no nutritional ingredients, and is not easy to breed bacteria. Cotton is one of the most important crops in the world, with large output and low production cost, which makes the price of cotton products relatively low. Cotton is an important economic crop and textile raw material in China, as well as an important strategic material, which plays an irreplaceable role in the development of China's national economy. my country's cotton planting area has not changed much, basically around 5 million hectares (about 75 million mu), and the cotton outp...
