Secondary salinization land improvement nutrient based on phosphorus agents

Abstract

The invention discloses a secondary salinization land improvement nutrient based on phosphorus agents. The secondary salinization land improvement nutrient comprises the following components in parts by mass: 120-180 parts of crop wastes, 250-400 parts of rotten feces, 160-200 parts of nanocarbon, 120-160 parts of nano calcium carbonate, 80-120 parts of purple coneflower leaf residues, 30-60 parts of wood vinegar, 8-20 parts of azotobacter chroococcum, 800-1200 parts of fertilizer polymerizer and 10-14 parts of microorganism fermenting agents. The secondary salinization land improvement nutrient based on phosphorus agents provided by the invention is convenient to use and capable of deeply improving the soil properties when applied to soil. Due to use of microbial phosphate-solubilizing preparations, the soil improvement is facilitated, and the utilization rate of phosphorus in soil is improved.

Description

technical field [0001] The invention relates to a soil improvement nutrient, in particular to a phosphorus preparation-based secondary saline-alkali soil improvement nutrient. Background technique [0002] Soil secondary salinization, also known as "secondary salinization", refers to the process of turning good cultivated land into "salinization" due to unreasonable cultivation and irrigation measures and changes in vegetation. It mainly occurs in my country's North China Plain, Songliao Plain, Hetao Plain, Weihe Plain and other places. There are three main reasons for the formation of secondary salinization: First, the drainage system of farmland is not smooth, and a large amount of water diversion irrigation has raised the groundwater level, increased the speed of groundwater moving upward through the soil capillary and the evaporation of groundwater, thereby increasing the groundwater and the lower level. The salt in the soil accumulates to the surface. Second, unreasona...

There are three main reasons for the formation of secondary salinization: First, the drainage system of farmland is not smooth, and a large amount of water diversion irrigation has raised the groundwater level, increased the speed of groundwater moving upward through the soil capillary and the evaporation of groundwater, thereby increasing the groundwater and the lower level. The salt in the soil accumulates to the surface. Second, unreasonable irrigation destroys the original soil salt water balance. Third, unreasonable agricultural production measures and destruction of vegetation aggravate the evaporation of soil water in the cultivated layer, resulting in surface alkali accumulation.
