Apocarya planting soil improver and soil improving method

Abstract

The invention provides an apocarya planting soil improver and a soil improving method and relates to the technical field of soil improvement. Aiming at the characteristics of soil in Quanjiao county, the invention provides the soil improver and the soil improving method. The soil improver is prepared from the following raw materials: turf soil, a microbial functional fungicide, humus, red earth and polymethyl methacrylate. According to the biological soil improver provided by the invention, by adding functional bacteria for fixing nitrogen and resolving phosphorus and potassium, the microbial environment of the soil is improved by biological means, so that not only can the power of hydrogen of the soil be effectively adjusted, but also the adaptability of apocarya on the soil is improved, and absorption and utilization of nutrients are enhanced. The scientific and reasonable soil improving method provided by the invention can be used for balancing soil nutrients, improving the soil fertility, enhancing the cold-resisting and drought-resisting abilities of crops, effectively preventing diseases such as soil-borne diseases and the like, improving the output of apocarya, and improving the quality of apocarya.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improver for planting pecans with thin shells and a soil improvement method. Background technique [0002] The main soil quality of Quanjiao Linnong's existing land is Suqiao yellow-white soil, also known as yellow mud. The land has good water and heat conditions, and the soil is neutral, with a pH of 6.4 to 6.8. The soil is mainly planted with rice, corn, wheat, rape and other crops, which are usually harvested twice a year. [0003] The main problems in the current contracted land are: heavy soil quality, prismatic block-prismatic structure in dry weather, poor permeability, shallow cultivated layer, poor tillability, poor nutrients, easy to drought and waterlogging, strong plasticity and expansion and contraction Mechanical leveling has seriously damaged the surface loam, and the old seedlings do not grow seedlings, and the yield is not high and unstable.

AI Technical Summary

Problems solved by technology

[0003] The main problems in the current contracted land are: heavy soil quality, prismatic block-prismatic structure in dry weather, poor permeability, shallow cultivated layer, poor tillability, poor nutrients, easy to drought and waterlogging, strong plasticity and expansion The surface loam soil is severely damaged by mechanical leveling, and the old seedlings do not grow seedlings, and the yield is not high and unstable

After a large amount of precipitation in the later stage, it was found that the soil erosion was serious. After the surface rotary tillage, it was found that the plow layer was peeled off, the subsoil was exposed, and the organic matter and various nutrient contents were even more scarce. 0.6-1.0g / kg, available phosphorus 0.5-4.5mg / kg, available potassium content is relatively normal 73-137g / kg, medium and trace elements except sulfur and manganese content are low and the rest are normal, the whole soil is still compact and sticky, easy to Hardening, poor ventilation and water permeability, extremely poor tillability, reduced number of beneficial microorganisms in the soil, reduced activity, slow nutrient transformation, and unfavorable growth of pecans with thin shells
