Problems solved by technology

However, the latest research has found that no matter how complex the chemical structure is, organic matter can be decomposed and utilized by microorganisms; at the same time, the protective effect of aggregates on organic matter is weak

Embodiment 1

[0055] Embodiment 1 A kind of method that improves soil (red soil) organic matter stability

[0056] 1. Experimental location: Yangtian Village Experimental Base, Zengcheng District, Guangzhou City, Guangdong Province.

[0057] 2. Specific steps:

[0058] (1) Preparation of materials: Collect 0-15cm soil samples from the field plots of the experimental base, remove stones and plant roots, and air-dry them through a 4mm sieve for later use; purchase commercial vermiculite, roast at 800-1000°C for 0.5h, and wait for After volume expansion and cooling, the stone is ground and processed into a powder (300 mesh) for later use; the rice straw is pulverized (passed through a 4mm sieve) for later use.

[0059] (2) Experiment setup: 4 treatments were set up in this experiment: ① treatment with vermiculite and amino acid powder (filling with vermiculite, amino acid powder and straw), ② treatment without vermiculite and treatment with amino acid powder (adding only amino acid powder, Str...

Abstract

The invention relates to the technical field of soil improvement, and discloses a soil organic matter stabilizer and application thereof. The soil organic matter stabilizer comprises minerals, amino acid powder and straw. The invention relates to a method for improving the stability of soil organic matters. The method comprises the following steps: (1) applying minerals, amino acid powder and straws into a soil plough layer; (2) regulating and controlling the soil moisture to 65-75% of the field water-holding capacity, and ploughing for 1-4 times. According to the soil organic matter stabilizer and the method for improving the stability of the soil organic matter, generation of mineral-bound organic matter can be promoted through minerals; the proportion of soil aggregates (especially large aggregates and small aggregates) is increased through the amino acid powder; the formation of a soil aggregate structure is promoted through a straw decomposition product; therefore, the stability of soil organic matters is improved.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a soil organic matter stabilizer and its application. Background technique [0002] Organic matter is the core component of soil. The current research on the formation and decomposition of organic matter in soil has extremely important theoretical and practical value for fertilizing soil fertility, improving soil structure, regulating carbon emissions and coping with global climate change. Organic matter takes organic carbon as the core, and the national standard determination method of organic matter is also based on the determination of organic carbon, and then the soil organic matter content is obtained by estimating the empirical coefficient. Therefore, improving the stability of organic matter is actually improving the stability of organic carbon in the soil. In the tropical and subtropical regions of southern my country, red soil is a typical zonal soi...
