Protective tillage method for water storage and high yield in the bottom powder ridge and crushed soil of dry land

Abstract

The protective tillage method for high-yield conservation tillage in powder ridges and broken soil at the bottom of dry land includes the following steps: (1) Before planting dry land crops, use a double-layer tillage tool matched with an auger bit and a plow to penetrate into the soil layer below 12 to 15 cm below the ground, and use The plow (9) sinks into the bottom of the plowing layer (10) and plows the hard soil layer (12) into a plowing layer (10), which is a hard soil layer (6) under the plowing layer (10); the dry land farming layer ( 13) Use the powder ridge auger bit (7) to penetrate 5-8cm into the soil to form a powder ridge layer (11); form an upper layer of crushed soil, middle layer of loose soil, and a deep immovable structure to build a unique "soil reservoir"; (2) put The dryland crops to be planted are sown or transplanted, and daily management is carried out according to the conventional planting management mode required by the crops. The dry land treated with loose soil at the bottom can promote the growth and development of dry land crops, increase yield and improve quality, realize the improvement of the supply level of "natural forces" such as live soil, water conservation, and ecology in dry land, and improve the production capacity of dry land crops.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to a protective tillage method for storing water and high yield in powdered ridges and crushed soil at the bottom of dry land. 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-...

[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
