In other countries of the world, various water-saving irrigation technologies are also being researched. Because of the different conditions in different countries, the water-saving technologies used are also different. Different water-saving technologies should be adopted according to their actual conditions. For example, some countries have adopted water-saving technologies such as sprinkler irrigation, micro-irrigation, and drip irrigation, all of which have achieved very good results. Israel has done a lot of work in water-saving irrigation and has accumulated a lot of experience. However, the cost of these water-saving technologies is high and most countries cannot learn. We hope to develop a water saving technology that farmers can use easily and at a low cost.
China has done a lot of research on agricultural water-saving technologies. The Fenhe Irrigation District conducted water-saving irrigation and water management studies before the start of the project. For example, the management system of “distribution of water by field, measurement and charging†was adopted. The experimental study, the principle of water balance in paddy field under the condition of water-saving irrigation, the research on the water saving and high-yield irrigation mode and mechanism of rice have achieved very good results.
In 1998, the international cooperation project research on "Impact of China's rice water-saving irrigation technology" was based on the original research, focusing on the research on the impact of rice water-saving irrigation on fertilizer use efficiency, especially nitrogen use efficiency. Seeking the "best water-fat balance" rice paddy field water and fertilizer management model; comparison of water-saving irrigation input and output, direct economic efficiency and indirect economic benefits; water-saving irrigation on water productivity. The "drying-wet alternate rice irrigation method" studied in the study not only saves water, but also increases production and income. Its research results are internationally leading. This method is simple, easy to grasp, and low in cost. Farmers can rely more on Tanggu and Festivals. Water irrigation measures to avoid the loss of crops, but also because of the low cost and simple methods, this technology can be better promoted.
As for the current status of agricultural development in China, improving the utilization rate of water resources and productivity must be achieved without delay. The soil moisture and drought management system should be used to analyze the soil moisture content in various agricultural areas, and timely adopt the most effective irrigation methods. Irrigation, increase crop production, and ensure the quality of agricultural products are worth promoting.
Soil moisture and drought management systems improve the technology to produce more food with a small amount of water
Water is the resource on which people depend for their survival. The demand for water in all production areas is very large. Especially in the development of agriculture, water is an indispensable resource. As far as the present situation is concerned, the countries that lack water are not just China. It can be said that there are water shortages in all countries of the world, and the crisis of water resources has become global worldwide. Therefore, how to produce more food with less water and increase the productivity of water resources is a very significant research topic. In the process of agricultural production, there are many water-saving technologies. Different countries have different technologies to suit their own needs. However, the constant is to use soil moisture and drought management systems and other related instruments to monitor the soil and timely irrigation. Water use efficiency.
