Biomass charcoal-based compound fertilizer special for cotton and preparation method thereof

Abstract

The invention discloses a biomass charcoal-based compound fertilizer special for cotton, which comprises the following raw materials in parts by weight: 30-50 parts of biomass charcoal, 24-36 parts of urea, 2-4 parts of bone meal, 4-8 parts of powdered rock phosphate, 12-30 parts of potassium sulfate, 4-10 parts of monopotassium phosphate, 1-3 parts of limestone flour, 1-3 parts of magnesium chloride, 1-3 parts of sulfur powder, 0.2-0.8 part of chelated trace elements, 0.3-0.8 part of an adhesive, 0.1-0.5 part of a sustained-release agent and 10-20 parts of water. By adopting the biomass charcoal-based compound fertilizer special for cotton, all nutrients required by growth of cotton are guaranteed, and the fertilizer is simple in fertilizing method and high in absorption utilization rate, the cotton yield can be effectively improved, the soil restoration effect is good, waste of the compound fertilizer is effectively reduced, pollution to soil, water resources and atmospheric environment is reduced, the preparation method is simple, the raw materials are easy to obtain, the cost is low, and the method is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a special biomass carbon-based compound fertilizer for cotton and a preparation method thereof. Background technique [0002] Cotton is the seed fiber of the Malvaceae plant. The flowers are milky white, and soon after flowering they turn dark red 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. Cotton was once an important strategic material in my country and played a pivotal role in the agricultural economic structure. my country's cotton production ranks among the top in the world. It is a large textile country and the largest cotton...

Problems solved by technology

According to statistics, the nutrient absorption and utilization rate of existing compound fertilizers is only 30-50%. The absorption and utilization rate of fertilizers is not high, and the loss is serious, resulting in waste. The lost fertilizer is easy to cause pollution to soil, water resources and the atmospheric environment.

Most of the existing compound fertilizers on the market are general-purpose fertilizers for higher plants, while the special compound fertilizers for cotton are few and of a single variety, and the effect of fertilizer absorption and utilization is not obvious, and the fertilization method is complicated, which increases the labor of farmers
