Freshwater irrigation to reduce soybean salt damage

The soil salinity caused soybeans, mainly due to the high salinity content in the soil and the low soil water potential, which caused the plants to absorb water and cause drought. Therefore, during the growth period of soybeans, those who have irrigation conditions should be irrigated in time when they return to salt (alkali). There are three reasons for irrigation to reduce salt damage: First, the surface salt and alkali are melted in the water, and the water is oozing into the ground, so that the salinity and alkali content of the plough layer is reduced, which is called “pressure salt (alkali)”; second, surface salt In the water, in addition to infiltrating into the underground, it can be discharged outside the ground through the drainage ditch, so that the salt content on the surface is reduced, called "washing salt (alkali)"; third, irrigation not only through "pressing salt" or "washing salt" Reducing the salt content of the plough layer also increases the soil water content, the soil water potential is increased, and the root water absorption of the plant is difficult to change.
Lands without irrigation conditions can make full use of natural precipitation to “wash” and “press” salt and alkali. Medium-sized rainfall, try to save rainwater in the land, and let the saline and alkali infiltrate into the ground through leaching to play the role of alkali. When the rainfall is large, the accumulated water can be discharged to the outside in time to achieve the effect of "washing" and "pressing".
