The saline-alkali land is mainly divided into primary saline-alkali land and secondary saline-alkali land. The secondary saline-alkali land is mainly caused by soil salinization caused by unreasonable irrigation and drainage system. In recent years, due to the unreasonable development of land by human beings, the phenomenon of soil salinization has become more and more serious. To prevent this situation from deteriorating, to protect the land on which we depend, use soil salinity meters for detection and treatment, and production. Guidance has become a key task in the field of modern agriculture.
The high salt content of soil is not only serious for the quality and safety of cultivated soil. The direct impact on agriculture is to curb the normal growth of crops. The main manifestation is that salt is too high to affect the photosynthesis and respiration of crops; Lipid and membrane proteins increase lipid membrane permeability and membrane lipid peroxidation, thereby affecting the normal physiological function of the membrane; hindering the protein synthesis of crops. The impact on agricultural production will lead to a reduction in agricultural production and a decline in the quality of agricultural products. Therefore, in the process of developing modern agriculture, it is especially necessary to give priority to solving the quality and safety of cultivated land.
The soil salinity meter is a professional instrument for the detection of soil salinity. It is also called soil EC meter. It can accurately check the soil salinity level, and provide evidence and support for scientific soil improvement and guiding correct production. At present, with the development of facility agriculture, annual production has placed a greater burden on the land. If the relationship between crop growth and land cannot be coordinated, soil problems are highly prone to occur. The application of soil instruments such as soil salinity meter is to provide modern farmers with more scientific soil testing methods, so that everyone can better understand the soil conditions, and on the other hand, to rationally develop and utilize cultivated soil, and achieve agricultural quality. At the same time of high yield, promote the sustainable development of agriculture.
