Located in the southernmost city of Handan, Hebei, its water resources are in short supply, which seriously affects agricultural development and construction in the area. In view of the severe shortage of water resources in Handan city, taking agricultural drought as a major issue is a necessary measure to promote agricultural development in the area. In the whole irrigation area, a water-saving and early-to-early “irrigation test center†was established to actively research and explore a soil moisture prediction and water-saving and early-resistance mechanism, with accurate, timely, and rapid soil moisture data, to correctly reflect the early-sensation. Agriculture has played a very important role early on. For the determination of soil moisture data, the soil moisture meter can be used for quick and effective analysis.
For the monitoring of soil moisture content in the Shudanhe Irrigation District of Handan City, the Water Saving and Early-Rate Irrigation Testing Center will be responsible for the overall responsibility. There will be five soil moisture monitoring stations, which will be measured using a soil moisture meter, respectively in Linyi, Matou and Feilin. There are 5 sub-irrigation areas in the township, Huangkou and Lianhuakou. The survey points are selected from the representative lands in the irrigation district and divided into two groups: irrigated land and early land. After the measuring points are selected, they cannot be arbitrarily changed. At the same time, the land points must not be repeated every time. The distance between them is less than 1 meter. From March 1st to November 21st each year, it is stopped 3 times a month, measured every 1 in the middle and late, measured after the rain or 2 days after the irrigation, and finished and reported to the “center†for finishing and then sent to the tune. The Water Division, the relevant Director, the Bureau of Defense and Early Warning Headquarters, and the Water Affairs Bureaus of the station where the stations are located.
Soil moisture has a highest, most suitable and lowest base point for crop growth. Below the lowest point, crop growth stops or even dies; above the highest point, the root system suffers from hypoxia, asphyxia, rot, plant growth difficulties, and even death; The most suitable range, in order to maintain the crop's moisture balance, to ensure good crop growth and development. When the water in the soil can not meet the needs of the crop, the crop will appear in the state of withering, and the wilting coefficient (that is, the soil moisture t when the crop is permanently withering) is the lower limit of the effective moisture of the soil, and the lack of moisture is harmful to the crop. Concentrated performance is as early as possible. The frequent occurrence of soil drought is characterized by the lack of available moisture for the soil to absorb and use. The root water absorption can not meet the needs of normal transpiration and growth of the crop. The soil moisture content falls below the wilting coefficient, and the middle loam soil is 6~8. Loam is 710, heavy loam is 9~12.
The relevant data of soil moisture content can correctly reflect the drought situation. According to the soil moisture content measured by soil moisture meter, it can correctly guide drought resistance, optimize the scheduling, and save water to ensure the harvest of crops in successive years. The soil moisture data measured by the Soil Moisture Tester is the general commander of the irrigation, even if it is only 4 times in the dry year, and the water per mu is not more than 45 cubic meters. From the sampling results and field comparison tests, the implementation of soil moisture monitoring, mu water-saving 40 cubic meters, an increase of 27 kilograms per mu, an increase of 8%, then deducted 50,000 acres of water-saving "00 million cubic meters a year, increase income Savings 18.08 million yuan.
