High-fertility sustained-release composite fertilizer special for sugarcane planting

Abstract

The invention relates to the field of composite crop fertilizers, and in particular relates to a high-fertility sustained-release composite fertilizer special for sugarcane planting. The composite fertilizer is prepared from the following raw materials in parts by weight: 15-18 parts of wheat bran, 6-8 parts of black humic acid, 8-10 parts of humic acid, 10-12 parts of mushroom stem, 8-10 parts of agrocybe cylindracea stem, 12-15 parts of sorghum straw, 3-5 parts of decomposed coal, 5-6 parts of sweet potato powder, 25-30 parts of peat soil, 6-8 parts of cellulose ether, 4-5 parts of starch ether, 3-5 parts of sodium tetraborate, 1-2 parts of silicon oil, 0.1-0.2 part of taurine, 2-4 parts of glutamine, 1-3 parts of black alum, 0.2-0.3 part of Twain 80, 6-8 parts of cane shoot shell, 10-12 parts of potassium metabisulfite, 15-18 parts of waste kelp residue, 12-15 parts of citric acid tripotassium and 3-5 parts of additives. According to the composite fertilizer provided by the invention, organic carbonized powder with an adsorption property is mixed with an organic fermentation liquid, medium trace elements and additives, a function of immobilizing nutrients is achieved, a sustained-release fertilization effect is achieved through a sustained-release filming agent, and the composite fertilizer is long lasting and efficient in fertilizer efficiency, the absorption and utilization rate of crops on the nutrient is high, plants are thick and solid and high in sweetness, and the planting benefits are improved.

Description

technical field [0001] The invention relates to the field of special compound fertilizer for crops, in particular to a special slow-release compound fertilizer for planting high-fertility sugarcane. Background technique [0002] Compound fertilizer plays an extremely important and indispensable role in modern agriculture. Compared with traditional organic fertilizers, it has the advantages of many types of nutrients, high content, high nutrient utilization rate, and convenient packaging, storage, and application. It is the future chemical fertilizer. direction of development. However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to formulat...

However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to formulate special fertilizers for different crops based on the characteristics of fertilizer requirements of different types of crops, and carry out scientific proportioning. On the basis of not destroying the soil balance, it can prolong the duration of fertilizer effect, improve soil vitality, promote the growth of crop roots, and increase root resistance. Nutrient absorption efficiency, avoiding invalid release of fertilizer effect, so as to achieve the purpose of improving planting efficiency, and realize sustainable green planting, and provide consumers with high-quality products
