We all know that this is the reason that plants will grow well only under the right conditions. The conditions mentioned here may be environmental conditions, soil conditions, etc. Therefore, as long as they are not satisfied, it is very likely that damage will be caused to the growth of the plant. If the soil salt is classified as an example, excessive salt in the soil will hinder the normal growth and development of the plant. As a result, the quality of the product deteriorates and the output decreases. Therefore, in the agricultural production, the use of soil salinity meter to measure soil salinity has become an important content in high-quality cultivation.

Why do you use a soil salinometer to measure soil salinity in the agricultural field? It is mainly because soil salt content exceeding the standard will affect the plant growth and cause soil salinity stress. Therefore, before answering this question, let us take a look at what the damage caused by soil salinity stress to plants is.
1. Influencing the photosynthesis of crops Under the stress of soil salinity, plants will not be able to absorb enough water and mineral nutrients, resulting in malnutrition, resulting in low chlorophyll content and affecting photosynthesis.
2. Respiratory effects on crops In general, the general trend when there is too much salt is the large amount of respiratory consumption and low net photosynthetic productivity, which is not conducive to plant growth.
3. Effects on plant cell membrane structure Soil salinity stress will directly affect the cell membrane lipids and membrane proteins, increase lipid membrane permeability and membrane lipid peroxidation, thus affecting the normal physiological function of the membrane.
4. Impede the synthesis of protein in crops Excessive soil salinity has a significant effect on protein metabolism, inhibits synthesis and promotes decomposition, and thus reduces protein content. In addition, it will also produce toxic substances in crops, resulting in poor plant growth, inhibition of root growth, and blackening and necrosis of tissues.
It can be seen that the damage caused by soil salinity stress to the plants cannot be ignored. Due to the excessive use of chemical fertilizers and pesticides in the past, the arable land in China has more or less soil salt content exceeding the standard. Therefore, green pollution must be developed. For planting and high-yield farmland cultivation, the first thing to do is to use soil salinity meter to measure soil salinity, and then guide the formulation and development of scientific improvement measures, and cultivate an excellent soil environment, so as to truly realize the goal of high quality and high yield of agriculture.
