Ecological method of storing water and enriching grass with crushed soil at the bottom of turf ridge

Abstract

An ecological method for storing water and enriching grass with crushed soil at the bottom of the lawn powder ridge, the steps are: step 1, before the lawn is planted, use a double-layer powder ridge cultivator with auger bit circular saw blades to penetrate into the soil layer below the ground 12 to 15 cm, Use the circular saw blade (13) with a diameter of 15 to 20 cm on the double-layer powder ridge cultivator to saw the deep soil to form a loose soil layer (15), and hard soil under the loose soil layer (15) layer (18); the topsoil layer (19) utilizes the powder ridge auger bit (9) to burrow into the soil for 5 to 8 cm to form a powder ridge layer (17); the powder ridge layer (17) and the loose soil layer (15) form an interlayer; step 2. Sowing or transplanting according to the conventional lawn cultivation method, no need to loosen the soil for 3 to 5 years after planting; Step 3. Carry out field water and fertilizer management according to the conventional lawn cultivation regulations. This method has the characteristics of excavating the supply level of "natural forces" such as lawn living soil, water conservation and ecology, reducing lawn irrigation and management costs, and improving the ecological quality of lawn abundant grass, and has great promotion value.

Description

technical field [0001] The invention relates to a farming method for crops, in particular to an ecological method for storing water and enriching grass with crushed soil at the bottom of a lawn powder ridge. 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 loose cultivation layer with a certain depth. 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 ...

[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 loose cultivation layer with a certain depth. 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
