Grassland bottom smash-ridging soil loosening water gathering and grass enriching ecological method

Abstract

The invention discloses a grassland bottom smash-ridging soil loosening water gathering and grass enriching ecological method. On a grassland untilled for a millennium, a grassland bottom area soil loosening tillage implement penetrates into a soil layer 10-15cm below the ground, soil on the lower portion of a surface soil layer (14) is sawed and tilled by a disk saw blade (11) with the diameter of 13-15cm to form a loose soil layer (12), and a hard soil layer (13) is formed under the loose soil layer (12). In the tillage process, the surface soil layer (14) and the hard soil layer (13) are kept untilled, only a small quantity of cracks are formed on the surface soil layer (14), and the original ecological shape of the surface soil layer is kept. The implement runs in one direction under power traction, deep cuts and pulverizes the soil, turns round and continues sawing, tilling and soil pulverizing cultivation for the soil on the lower portion of the surface soil layer (14) after reaching a grassland edge end point. A loose soil layer (10) with 13-20cm or deeper loose soil is built, namely, a 'soil reservoir' is built, and a grassland water gathering and holding and ecological grass enriching soil ecological environment system of a protective grassland with 'upper non-tillage, middle loosen soil and lower solid leak-proof original soil' lands can be built.

Description

technical field [0001] The invention relates to a farming method for crops, in particular to an ecological method for loosening soil, collecting water, and enriching grass at the bottom of a grassland. Background technique [0002] For thousands of years, the traditional crop farming methods in our country have used machinery, animal power or manpower to cultivate the soil to create a certain depth of loose topsoil. It can promote soil aeration, adjust soil temperature, and promote nutrient transformation, etc.; but it also has disadvantages: (1) Plowing makes wet soil bare, which accelerates the loss of soil moisture, which is not conducive to moisture conservation, especially in the case of spring drought. (2) Plowing accelerates the oxidative decomposition of soil organic matter, resulting in a decrease in soil organic matter content. (3) Plowing requires a large power input, which increases the cost of agricultural production. (4) Long-term plowing is easy to form plow...

Problems solved by technology

[0002] For thousands of years, the traditional crop farming methods in our country have used machinery, animal power or manpower to cultivate the soil to create a certain depth of loose topsoil. It can promote soil aeration, adjust soil temperature, and promote nutrient conversion, etc.; but it also has disadvantages: (1) Plowing makes wet soil bare, which accelerates the loss of soil moisture, which is not conducive to moisture conservation, especially in the case of spring drought

(2) Plowing accelerates the oxidative decomposition of soil organic matter, resulting in a decrease in soil organic matter content

(3) Plowing requires a large amount of power input, which increases the cost of agricultural production

(4) Long-term plowing is easy to form plow bottom layer, causing soil compaction and affecting soil permeability, etc.

(5) In arid and semi-arid areas, the soil of the field after plowing is exposed, which is likely to cause soil wind erosion, lead to degradation of soil fertility, form sandstorms, and damage the ecological environment

[0004] The ultra-deep plowing of Fenlong technology activates a variety of land resources, restores soil, increases natural precipitation, and improves ecology. It has huge scientific and application potentials. It can build a large-scale green ecological agriculture. + Saline-alkali land + degraded grassland + marginal land + river water + offshore waters" and other "green super agriculture" pattern changes, so that grain, meat, milk, fish and other agricultural products can be produced with high quality, and more natural precipitation can be stored on land. The use of water resources, as a whole, solves the mismatch between the current agricultural resources and the needs of population development. As a result, in order to ensure food security, agricultural production methods have to pursue high-yield or super-high-yield, compost fertilizers and use more pesticides, resulting in soil and water bodies. , the air is easily polluted and difficult
