Method for rapidly increasing soil organic matter of dry-farming land

Abstract

The invention is the improvement of soil fertility in agricultural technology, is a method for rapidly enhancing the soil organic matter of drought plowland. The invention uses the rotary cultivator to crush and the stubble and the roots about 10-20 cm below the ground and return itto field after harvestry and before getting frozen; it uses the plant straw as material, incoulates microbe compound germ agent, it is made up outdoor by semi-pit yeasting; the straws are rotten and heated to preserve fertilizer, it is scattered into soil in spring. The invention can maintain the balance of soil organic matter, it improves the structure of soil, promotes the benign circulation of agriculture zoology.

Description

technical field [0001] The invention belongs to the improvement of soil fertility in the field of agricultural technology, and relates to a method for rapidly increasing soil organic matter. Background technique [0002] The amount of soil organic matter content is an important indicator of soil fertility, but over the years, due to heavy use and light cultivation, soil organic matter has dropped significantly. For example, the soil organic matter in Lanxi County, Heilongjiang Province, China was 6-8% at the beginning of reclamation, and now it has dropped to 3-8%. 4%; soil organic matter in Tieling County, Liaoning Province, China has dropped from 2-3% in 1960 to 1-1.4% in 1996. [0003] For a long time, farmers have been using organic fertilizers such as barn manure and green manure to ensure the balance between supply and demand of soil organic matter. [0004] In the United States, the no-till method is used to return all the straw produced on the ground to the field to...
