Description

Water-saving drip irrigation device for saline-alkali soil planting Technical Field The invention belongs to the technical field of agricultural irrigation, and particularly relates to a water-saving drip irrigation device for saline-alkali soil planting. Background Saline-alkali soil is a kind of soil with excessive salt and alkali content, which results in deterioration of physical and chemical properties of soil and influences normal growth of plants. Because the saline-alkali soil has high salt content, when crops are planted in the saline-alkali soil, irrigation is needed, irrigation water can dissolve salt on the surface layer of the soil, and the salt is brought to the deep layer of the soil through leaching, so that the salt concentration of the surface layer soil is reduced, and a proper salt environment is created for crop growth. And the crop growth needs sufficient moisture, and the saline-alkali soil possibly contains a certain amount of available water, but the water absorption of the crop root system is difficult due to the influence of salt, so that the irrigation can supplement the soil moisture, the moisture requirement of the crop growth is met, and the growth and development of the crop root system are facilitated. The tradition can adopt irrigation modes such as drip irrigation, sprinkling irrigation, and these irrigation modes can control the irrigation water yield, but spun water is mainly through the top layer infiltration downwards, but under the condition that runs into soil surface salinity gathering more, top layer soil is poor in permeability to lead to moisture to be difficult to infiltration downwards, not only increased the water yield of irrigation, cause water waste, the root system is difficult to absorb deep moisture moreover.
