Comprehensive low-moisture soil drainage promoting device and implementation method

Abstract

The invention discloses a comprehensive low-moisture soil drainage promoting device and an implementation method, and relates to the field of agricultural drainage devices and implementation methods. The comprehensive low-moisture soil drainage promoting device is composed of an irrigation channel, a drainage channel and drainage pipes. The irrigation channel and the drainage channel are located on the two sides of a rice field parcel. The drainage pipes are each in a U shape, the opening ends of the U shapes of the drainage pipes are connected with the irrigation channel, and the bottom ends of the U shapes of the drainage pipes are connected with the drainage channel. The drainage pipes are located in a rice husk layer. An overburden layer is arranged above the rice husk layer, and drainage ways are arranged in the overburden layer. The implementation method of the comprehensive low-moisture soil drainage promoting device comprises the three steps including irrigation channel and drainage channel establishing, paving drainage and deep scarification farming. The comprehensive low-moisture soil drainage promoting device and the implementation method are suitable for low-moisture soil, and enable the soil to be in a dry and wet alternating process, an aerobic environment needed for growth is provided for crops, the effectiveness of soil nutrients is improved, and the activity of the root system is improved; generation of SO2 or H2S or other toxic gases in soil is reduced, and the root system is prevented from being poisoned; and the content of water in the soil is proper, the bearing force of the soil is good, mechanical harvesting is facilitated, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of agricultural drainage devices and implementation methods, in particular to a low-humidity soil comprehensive drainage device and implementation method. Background technique [0002] Low-humidity soil refers to the soil distributed in low-lying areas with relatively sticky soil texture and poor ventilation and water permeability. This type of soil has high water content, poor drainage, prone to waterlogging, and is not conducive to mechanical operations. In recent years, the proposal of "using rice to control waterlogging" has greatly improved the low-humidity soil. Therefore, the rice industry in Heilongjiang has vigorously developed. With the development of rice production, problems have also emerged. The existing production methods believe that rice production It must be soaked in water during the whole growth period. Although rice needs water during the growth process, the root system needs to grow and absorb n...

This type of soil has high water content, poor drainage, prone to waterlogging, and is not conducive to mechanical operations.

In recent years, the proposal of "using rice to control waterlogging" has greatly improved the low-humidity soil. Therefore, the rice industry in Heilongjiang has vigorously developed. With the development of rice production, problems have also emerged. The existing production methods believe that rice production It needs to be soaked in water during the whole growth period. Although rice needs water during the growth process, the root system needs to grow and absorb nutrients in an aerobic state. environment, if the rice is flooded for a long time, first, the soil will always be in a reduced state, and there will be a lack of high-valent ions such as oxygen, iron, and manganese around the root system. In this environment, these high-valent ions will be reduced from high-valent to low-valent. Effectiveness It is attached to the root system, which will also lead to a decline in root system activity; second, the sulfate ions in the soil are reduced to SO 2 or H 2 Toxic gases such as S can easily poison the root system and cause crop death; third, the long-term flooding of the soil can easily soften the stems during the rice maturity stage, and the rice is easy to lodging; The decomposition rate of organic residues is slow, and the availability of nutrients such as nitrogen, phosphorus, and potassium is reduced, which limits the absorption of soil nutrients by crops; fifth, the high soil moisture content is not conducive to mechanical harvesting in autumn, and the soil bearing capacity is poor, which limits mechanical harvesting
