Compound fertilizer for increasing sugar content of sugarcane and production method thereof

Abstract

The invention discloses a fertilizer special for sugarcane and a production method thereof. Raw materials of the fertilizer include inorganic fertilizers, organic materials, secondary element, microelement and botanical fungicides. The fertilizer is prepared from, by weight, 30% to 38% of total nutrients (N, P2O5 and K2O), larger than or equal to 15% of the organic materials, 0.1% to 0.5% of the secondary element, 0.04% to 0.1% of the microelement and 1% to 10% of the botanical fungicides (please see GB18877-2009 Organic-Inorganic Compound Fertilizer National Standard for the notation). According to the fertilizer special for the sugarcane, the ratio of nitrogen to phosphorus to potassium is reasonable, fertilizer shortage is avoided in the growth stages of the sugarcane, and the secondary element, the microelement and the organic materials are provided; in addition, cane beetles and borers can be effectively prevented, and sugarcane smut can be effectively inhibited; as for the sugarcane planted with the fertilizer special for the sugarcane, emergence seedlings are tidy, stalks are thick, lodging is not prone to occurrence, the number of plant diseases and insect pests is small, the average increase yield per mu ranges from 1,000 kg to 2,000 kg, the sugar content is increased by 1% to 3%, and economic benefits are greatly increased.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and in particular relates to an organic-inorganic compound fertilizer for sugarcane and a production method thereof. Background technique [0002] Sugarcane (Saccharum) is an annual or perennial perennial tropical and subtropical herb with erect stems, thick and juicy, often covered with white powder on the surface. The leaves are alternate, with small sharp teeth on the edge, and the flower spikes are compound racemes. The sugar content is 17-18%. Sugarcane is a temperature-loving and light-loving crop. The annual accumulated temperature needs to be 5500℃~8500℃, the frost-free period should be more than 330 days, the annual average air humidity should be 60%, the annual precipitation should be 800~1200mm, and the sunshine hours should be more than 1195 hours. . Sugarcane has a wide range of adaptability to soil, and clay loam, loam, and sandy loam are better. When the soil pH value is 4.5-8.0,...

Problems solved by technology

As above, in this invention, the controlled and slow-release function of inorganic fertilizers is mainly achieved by the coating method, which improves the utilization rate. It also does not improve the soil, increase organic matter, and has no insect repellent and antibacterial functions. Chemical agents need to be used again. Not only the effect Not good, but also increased labor costs
