Rice field bottom smash-ridging soil pulverizing tillage and ecological cultivation method

Abstract

A rice field bottom smash-ridging soil pulverizing tillage and ecological cultivation method includes the steps: first, penetrating into a soil layer 12-15cm below the ground by a rice field interlayer soil pulverizing efficient tillage implement when soil in a rice field is dry, cutting deep soil by a disk saw blade (15) with the diameter of 15-20cm to form a loose soil layer (14), forming a hardsoil layer (17) under the loose soil layer (14), performing rotary tillage on a plough layer (18) by a rotary blade (8) to form a pulverized soil layer (16), forming an interlayer between the pulverized soil layer (16) and the loose soil layer (14), forming a 'sandwich' structure with upper shallow loose soil, middle fixed soil and deep loose soil' and building a unique 'soil reservoir'; second,performing rotary tillage on dry soil by smash-ridging machinery entering the soil by 8-10cm, smashing the surface soil of the rice field, or performing slurry tillage on 8-10cm soil under the condition of water layers; third, performing seeding or transplantation according to a conventional planting method of rice; fourth, performing rice field water and fertilizer management according to conventional management modes.

Description

technical field [0001] The invention relates to a method for cultivating crops, in particular to a method for cultivating and ecologically cultivating paddy fields with powdered ridges and crushed soil. 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 plo...

[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
