Problems solved by technology

[0010] The present invention aims to solve the problem of the straw degradation process in the prior art, because the straw has a high C / N ratio and is difficult to be decomposed by microorganisms in the natural state, resulting in a long cycle of decomposition and transformation in the soil after the straw is returned to the field, making it difficult to be used as a seasonal crop. Fertilizer problem

[0075] Example 3: Effects of rice straw returning to the field on plow layer soil

[0076] Soil bulk density is an important detection index of soil physical and chemical properties. It refers to the ratio of the mass of dry soil per unit volume to the same volume of water in the natural state. It reflects the soil structure, organic matter content and other comprehensive conditions. The level of soil bulk density index It will directly affect the soil porosity and pore size distribution, soil penetration and soil fertility, and the soil penetration and root activity of plant roots, which further affect the growth and development of plants. Changing the soil bulk density of saline soil, reducing the soil bulk density, making the soil loose, having good porosity, and increasing the water content are the important goals of soil improvement in saline-alkali soil.

[0077] Soil porosity refers to the percentage of solid particles in the soil. Its size is closely related to the air...

Abstract

The invention provides a method for improving soil through rice straw returning. The method comprises the steps that firstly, rice straw is pretreated, the pretreated rice straw is stacked into a long trapezoid, and a biological agent is adopted for fermenting the rice straw to obtain straw a composted substance. The adopted biological preparation has the powerful composting effect on straw, in the fermentation process, a large number of functional bacteria are bred, and various special-effect metabolites are generated, and therefore growth and development of crops are stimulated; crop disease resistance, drought resistance and cold resistance are improved, after functional bacteria enter soil, nitrogen fixation, phosphorus dissolving, potassium dissolving can be achieved, the soil structure can be improved, and the chemical fertilizer utilization rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for improving soil by returning rice stalks to fields. Background technique [0002] Soil microorganisms and enzymes are important components of soil biochemical properties, and play an important role in soil nutrient transformation cycles and organic matter decomposition. They are an important indicator of soil fertility and are often used to evaluate the biological properties of soil quality. It has become one of the research hotspots in the field of soil science. Straw returning to the field provides a sufficient carbon source for soil microorganisms, promotes the growth and reproduction of microorganisms, and improves soil biological activity. In recent years, many scholars have conducted a series of studies on soil enzyme activity and microbial population under the condition of straw returning from different angles. Straw returning to the field can...
