Novel sugar-containing and phosphorus-containing fertilizer

Abstract

The invention discloses a novel sugar-containing and phosphorus-containing fertilizer. The novel sugar-containing and phosphorus-containing fertilizer is characterized in that the carbon-phosphorus ratio of the novel sugar-containing and phosphorus-containing fertilizer is (1-15): 1 according to the mass of carbon and phosphorus elements, and the novel sugar-containing and phosphorus-containing fertilizer is divided into a low-carbon type (the carbon-phosphorus ratio is (1-4): 1) and a high-carbon type (the carbon-phosphorus ratio is (4-15): 1); and the carbon source contains any one or more of glucose, cane sugar, cane molasses and beet molasses. The novel sugar-containing and phosphorus-containing fertilizer disclosed by the invention is applied to soil in a dripping or strip applicationmanner, and the phosphorus utilization efficiency of crops is improved by regulating and controlling the inherent phosphorus-dissolving microbial activity in the soil. After the novel sugar-containing and phosphorus-containing fertilizer disclosed by the invention is used at multiple test sites, the soil respiration is enhanced, the phosphatase activity is remarkably improved, the soil water-soluble phosphorus concentration is remarkably increased, and the yield of crops is remarkably increased.

Description

technical field

[0001] The invention belongs to the technical field of agricultural planting and chemical fertilizers, and in particular relates to a novel sugar-containing and phosphorus-containing fertilizer. Background technique

[0002] Soil microorganisms play an important role in the activation and utilization of soil phosphorus. Microorganisms can quickly fix the phosphorus fertilizer applied to the soil to form microbial biomass phosphorus; during the turnover process of microbial biomass phosphorus, this part of phosphorus can be released into the soil (Gyaneshwar et al.2002) and become the source of soil available phosphorus Important source (Richardson et al. 2009). Phosphatase secreted by phosphorus-dissolving microorganisms can hydrolyze organic phosphorus into orthophosphate for plant uptake and utilization; organic acid anions secreted by microorganisms can chelate phosphate radicals precipitated by metal cations; microorganisms secrete protons and release CO...
