The water holding capacity of soil in Huaibei area is closely related to the soil texture, structure and porosity. As far as soil texture is concerned, the water holding capacity of various types of soil is basically increasing as the soil texture becomes more viscous. For example, the loamy soil in the Loess Loess covers 22% to 31% of the field volume, 22% to 34% of the clay soil, and the loamy soil in the Saurosan Blackfield has 22% to 32% of the field capacity. The clay soil is From 22 to 36%, sandy soils in fluvo-aquic soils have a field capacity of 16-22%, loamy soils of 21-35%, and clays of 23-35%. The strength of soil water retention performance can only explain the ability of soil to retain moisture, but it cannot explain the effectiveness of soil moisture. The range of available soil moisture depends mainly on the amount of water in the field and the amount of withered water. Withered water content generally increases with the viscidity of the soil texture. The amount of soil water holding capacity in the Huaibei area is affected not only by the texture but also largely by the structure and porosity of the soil.
The determination of soil moisture in Huaibei area by a soil moisture quick tester found that the soil structure in Huaibei area was poor, which was also an important cause of poor soil moisture status. Therefore, more organic fertilizers should be applied. In particular, green manure should be vigorously developed to increase soil organic matter, promote the formation of granule structure, and improve the pore status of the soil in order to improve the ability of the soil to store water and protect water and ventilation.
Effect of Soil Moisture Analyzer on Soil Moisture Control in Huaibei Area
Soil moisture is one of the important factors of soil fertility. Too little or too much soil moisture not only directly affects crop growth, but also affects the coordination of fertility factors such as soil nutrients, air and heat. For example, the growth and composition of soil air, the conversion and release of nutrients, the increase and decrease of soil temperature, and the activity of soil microorganisms are all closely related to the amount of water in the soil. The soil moisture quickness meter can effectively measure and analyze the moisture content in the soil. Huaibei area in our province often suffers from early onsets, and the soil moisture changes greatly, resulting in a large part of the land, and the yield is unstable. Therefore, studying the water properties of soil in Huaibei area, grasping the law of soil moisture changes, taking effective measures, and reasonably regulating soil moisture are of great significance for realizing agricultural high-yield and stable production of Huaibei commercial grain base. The soil moisture meter is more effective in measuring moisture.
