Description
Technical Field
The invention relates to the technical field of non-woven fabric materials, in particular to a non-woven fabric material wrapped outside a concealed pipe during drainage of the concealed pipe in saline-alkali soil and a preparation method thereof.
Background
Non-woven fabrics, also known as non-woven fabrics, are made of oriented or random fibers, are a new generation of environmentally friendly materials, and are called fabrics because of their appearance and certain properties. The non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity or irritation, rich color, low price, recycling and the like. For example, the polypropylene (pp material) granules are mostly adopted as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying a line and hot-pressing coiling.
Salinization is one of the main problems of land degradation in the world at present, and China is mainly distributed in North China plains, northeast plains, northwest inland regions and coastal regions. The generation of saline-alkali soil makes large-area soil resources difficult to utilize, and the comprehensive agricultural production capacity is reduced. Saline-alkali soil is a generic term for soil and alkaline earth. The saline soil mainly refers to saline soil containing high chloride or sulfate, the soil is alkaline but not necessarily high in pH value, the alkaline earth refers to soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the content of organic matters in the saline soil is low, the soil fertility is low, the physical and chemical properties are poor, more anions and cations are harmful to crops, and the seedlings of the crops are not easy to promote. Saline-alkali soil is easy to harden, has small porosity and poor water and air permeability, and is easy to cause soil erosion and surface runoff. The excessive salt content in saline-alkali soil has adverse effect on the growth and development of plants. The saline-alkali soil improvement method comprises the following steps: water conservancy improvement, agricultural technology improvement, biological improvement, chemical improvement and the like. The concealed conduit alkali discharge is one of water conservancy improvement, and is characterized in that fresh water is infiltrated through irrigation or rainfall to elute the salt in soil, and the soil body is discharged through the concealed conduit to gradually desalt the soil. Along with the increase of the soil desalination degree and the infiltration of fresh water, the infiltration of fresh water can be superposed on the original high-salinity underground water to form a fresh water layer, the fresh water can extrude the saline water to a concealed pipe to be discharged, so that the thickness of the fresh water layer is gradually increased, and the desalination degree is gradually increased along with the increase of the alkali-improving age, so that the underground water desalination layer is thicker and thicker, and the saline and alkaline are radically treated. The hidden pipe drainage technology is an important technical measure for farmland water logging, waterlogging prevention and treatment and saline-alkali land management, and is widely used at home and abroad. In order to prevent soil particles from blocking the concealed conduit and improve the drainage efficiency of the concealed conduit and the continuous effectiveness of drainage, a non-woven fabric material is usually wrapped outside the concealed conduit, the existing non-woven fabric material is easy to decay, the mildew-proof effect is poor, and therefore the drainage effect is affected, and the non-woven fabric special for drainage of the concealed conduit of the saline-alkali soil is absent at present.
