Abstract

The invention discloses a soil conditioner for increasing content of humus in red-yellow muddy field soil in southern double-cropping rice regions. The soil conditioner is prepared from decomposed organic fertilizer, compound fertilizer, humus, biomass charcoal and a composite microbial agent. The soil conditioner provided by the invention contains the beneficial components such as the organic fertilizer, the biomass charcoal, the humus and the microbial agent, wherein the organic fertilizer, the biomass charcoal and the humus help to improve the soil structure, reduce soil bulk density and enhance soil permeability; the humus is rich in organic carbon content, thus being capable of supplementing the organic matter content in the soil; the organic carbon in the humus has homology with thebiomass carbon, so that the content of the soil humus can be increased after the humus and the biomass carbon are applied at the same time; the composite microbial agent is beneficial to promotion ofsoil microbial activity and nutrient release as well as enhancement of soil nutrient supply; after being applied, the soil conditioner helps to alleviate soil hardening of the red-yellow muddy field in the southern double-cropping rice regions, improve the soil environment, increase the soil humus content, fertilize the soil and promote rice growth, thus achieving the effect of increasing rice yield.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner for increasing the humus content of soil in red-yellow mud fields in southern double-cropping rice areas and an application thereof. Background technique [0002] Paddy soil is the most important type of soil cultivation in the double-cropping rice area in southern my country. In the early 1980s, low-yield paddy soil accounted for 26% of the total area. Improving soil structure and improving productivity of low-yield paddy soil through soil improvement is one of the important measures to ensure national food security. The red-yellow mud field is a kind of medium-low-yield paddy soil in the red-yellow soil area in southern my country. It is mainly developed from various rock weatherings and red soil wasteland or dry land on the Quaternary red soil after reclaiming and planting rice. It mainly includes red mud fields, Soil types such as yellow mud field,...
