The combination of drip irrigation technology and film-covering technology has become a new type of agricultural irrigation technology called drip irrigation technology under the membrane. This technology not only reduces the salinity of the main root zone of the crop, provides a good water and salt environment for the crop, but also inhibits the soil. evaporation. It minimizes the waste of water resources and evaporation of soil moisture, and promotes the high yield and income of crops. The content of soil salinity is an important indicator of crop growth. For salt, it can be measured and recorded using a soil salinity recorder.
In recent years, drip irrigation technology has been applied to the development of native saline-alkaline land and prevention and control of secondary salinization. At present, the technology for saving water in drip irrigation under the membrane in Xinjiang has developed rapidly. It has played an important role in promoting cotton production and achieving precise management of cotton production. However, a new secondary salinization agriculture has emerged in Xinjiang Oasis farmland. In Xinjiang, where the climate is dry and evaporation is large, a special bottom-up moisture migration process leads to the accumulation of salt in the soil surface, and there is potential for secondary soil salinization risk in long-term continuous cropping soils. There are many reports on the trend of soil salinity changes in greenhouses in China. It has been found that the soil salinity increases with the extension of the planting period, and the pH value tends to decrease. However, the effect of drip irrigation under the membrane on the change of soil salinity with the extension of years is studied. Very little.
The soil salinity recorder measured and analyzed the soil under drip irrigation under the membrane and found that due to its special covering structure, it changed the water-heat balance of the soil in the ecological environment and natural state, especially changed the physical and chemical properties of the soil. This also provides a scientific basis for the sustainable development of membrane drip irrigation technology.
