In the process of agricultural development, the use of water to improve the utilization of water resources has been studied and discussed in recent years. However, a large number of experimental data show that after the improvement of irrigation technology, new changes have taken place in rice water consumption and water demand patterns. Therefore, the reasons for the reduction in water consumption of rice using water-saving irrigation techniques, as well as theoretical calculation methods, need further analysis. For the determination of soil moisture content, soil moisture analyzers can be used for effective analysis.
Over the years, a system consisting of soil moisture, crop physiology, agro-meteorology, and farming measures has been organically formed. Using the field plots and rainfall simulation facilities at the experimental station of the wheat farm, a series of experimental studies of paddy rice irrigation technology have been carried out, forming a festival. Water, high-yield, high-quality, low-loss, and lodging-resistant rice soil moisture control irrigation technology (hereinafter referred to as irrigation control), and promote the application of large-scale rice irrigation areas, economic and social benefits are very significant.
While the soil moisture meter was used to study the controlled irrigation of rice, the water requirement and its regularity of rice under the new irrigation technology were tested. The results showed that the water absorption and water transport in the roots of rice can be changed through the control and adjustment of soil moisture in paddy fields. As well as stomatal opening conditions and other physiological processes, and the formation of a water-saving growth environment, the rice body and the environment are in a new state of balance and coordination, a new change in the rice water requirement law, a double physiological and ecological water-saving effect. In this paper, the mechanism of water saving in irrigation control is analyzed, and the calculation method of water requirement for controlled irrigation rice is discussed.
The soil moisture meter was used to monitor the soil moisture content. After comparing and analyzing the soil water content after irrigation, it can be known that adopting advanced irrigation technology to adjust the moisture content of the soil will significantly reduce the water requirement of rice. The physiological and ecological water demand law has undergone a new change, indicating that the water demand of rice and its changing rules are closely related to the irrigation technology. After the reduction of evaporation between trees and leakage in the field, the soil environment is improved, the rice body and the ecological environment are in a new state of coordination, which is more conducive to the high yield of rice.
