Cultivation and Ecological Cultivation Method of Powder Ridge Broken Soil at the Bottom of Paddy Field

Abstract

The paddy field bottom ridge broken soil tillage and ecological cultivation method comprises the following steps: step 1, when the paddy field is relatively dry soil, use paddy field interlayer broken soil efficient tillage tools to penetrate into the soil layer below the ground 12-15 cm, and use a diameter of 15 cm. The ~20cm circular saw blade (15) cuts the deep soil to form a loose soil layer (14), and below the loose soil layer (14) is a hard soil layer (17); Broken soil layer (16), in the process of tillage, an interlayer is formed between the crushed soil layer (16) and the loose soil layer (14), forming a "sandwich" structure in which the upper layer of shallow loose soil, the middle layer of soil does not move, and the deep layer of soil is loose , to build a unique "soil reservoir"; step 2, before rice transplanting, use powder ridge machinery to bury 8~10cm into the soil for dry soil rotary tillage, and crush the surface soil of the paddy field; or under the condition of water layer, burrow 8~10cm into the soil Carry out paddle tillage; Step 3, sowing or transplanting according to the conventional paddy planting method; Step 4, perform paddy field water and fertilizer management according to the conventional management mode.

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
