High-yield farming method for sugarcane perennial roots in dry land with loose soil and water storage

Abstract

The invention discloses a high-yield farming method for perennial root sugarcane bottom loosening soil and water storage for many years in dry land. Specifically, after harvesting the sugarcane perennial root sugarcane in the dry land in the same year or the second year, using a horizontal-axis circular saw type cultivator to penetrate the ground below 12 to 15 cm Use a circular saw blade with a diameter of 15-20cm to plow the deep soil to form a loose soil layer, and below the loose soil layer is a hard soil layer; during the cultivation process, keep the sugarcane ground cultivation layer and the sugarcane soil below 10-15cm The soil layer does not move, only a small number of cracks are formed, and the original ecological state of the surface soil layer is maintained; a unique "soil storage reservoir" is built to allow the sugarcane root system to penetrate deep into the soil area about 40cm deep, which is beneficial for sugarcane to resist drought, high temperature, and low temperature. Promote sugarcane water, balanced supply of nutrients and increase yield and sugar, and can be increased from the current cycle of 2 to 3 years for perennial sugarcane to 3 to 4 years or longer.

Description

technical field [0001] The invention relates to a farming method for crops, in particular to a farming method for high-yield farming with loose soil at the bottom of sugarcane perennial roots for water storage in 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) Lon...

[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
