The amount of water resources used for irrigation in China is very large. Agricultural water accounts for about 70% of the country's total water use, of which more than 90% is used for irrigation. At present, the average national irrigation water utilization rate is only 43%. The output of agricultural products is far lower than that of developed countries and there is great potential for saving water. The measurement of farmland moisture and precision irrigation are an integral part of precision agriculture. Through rapid and accurate measurement of soil moisture, the understanding of farmland moisture conditions is not only conducive to the implementation of water-saving irrigation, but also accurate water supply is also conducive to improving crop yield and quality. . Soil temperature is also of great significance to agriculture.
Accurate measurement of soil moisture can help us to perform accurate irrigation. There are many methods for measuring soil moisture. The most primitive and precise method is the drying method. However, it takes a long time and must be measured in the laboratory. The continuous and long-term online measurement of soil moisture is difficult to meet the measurement requirements of precision agriculture. For these factors, our company and Zhejiang University organized and developed a new professional measuring instrument for measuring soil moisture and temperature—a soil moisture temperature tester. By using it, we can quickly and accurately measure the moisture content in soil and apply it. Conduct long-term monitoring outdoors.
The necessity of soil moisture measurement
The necessity of soil moisture measurement The total water resources in China are relatively large but the water consumption per capita is relatively small. China is a water-deficient country, and most of our country's grain production is irrigated through taxes and fertilizers, but it is generally present. One problem is that our country's right and wrong are not restrained. The amount of fertilization is much higher than the demand. This also leads to the pollution of water resources. Therefore, it is better to use a soil tester to understand the paddy fields before fertilizing. The soil nutrient status is then scientifically and reasonably fertilized. The method of irrigation does not implement the flooding method. Before the irrigation, the quick soil moisture analyzer is used to understand the water shortage condition in the soil and the appropriate irrigation is performed. The effect will be better.
