Analysis of Portable Soil Moisture and Temperature Analyzer for Analyzing the Relationship between Green Manure and Soil Water and Heat in Tea Garden

The organic tea industry has grown more and more rapidly in recent years, which has limited the use of various types of inorganic and organic fertilizers in tea plantations. How to solve the problem of soil fertility in tea gardens? This requires an increase in green manure. Since planting green manure is safe and reliable for improving soil organic matter and soil quality, interplanting green manure through tea gardens is an important measure to ensure the sustainability of soil fertility in organic tea gardens. In order to clarify the biomass characteristics of different green manures and the effects of green manure rhizosphere on soil moisture and temperature during the growth period, the green manure varieties suitable for interplanting tea plantations were screened. For the impact of green manure on soil water and heat, a portable soil moisture temperature speedometer was used for determination and analysis.

According to the portable soil water temperature and temperature tester, it is found that the shade of the plant stems and leaves on the soil surface during the growth process of the green manure inevitably affects the water content in the rhizosphere soil of the plant, thus affecting the microclimate of the tea garden soil. After planting green manure in the soil, the plant stems and leaves masked, which reduced the evaporation of soil surface moisture, thereby increasing the water content of the top soil in the plant rhizosphere, and the effect of crops with high plant height and stem and leaf yield on the inhibition of rhizosphere soil moisture evaporation. Stronger, thus increasing the water content of the top soil of the green manure rhizosphere and enhancing the crop's ability to resist drought.

During the growth of green manure, the plant stems and leaves mask the soil surface, which will also affect the temperature change of the plant rhizosphere soil, thus affecting the microclimate of the tea garden soil. During the day when the outside temperature is relatively high, the temperature of the top soil in the rhizosphere of the green manure is lower than the temperature of the uncovered soil topsoil due to the sheltering effect of the plant stems and leaves. The difference in temperature is related to the size of the plant's stems and leaves to the surface cover, and the plant is generally tall and stalked. The leafy green manure plants have a strong shadowing effect on the topsoil, and the corresponding rhizosphere topsoil temperature is low. The regulation of land surface temperature by green manure plants is quite obvious.

According to the effect of portable soil moisture temperature quickness tester on the change of soil moisture in different rhizosphere soils of different green manure varieties, the plants grow fast, the stems and leaves are lush, and the green manure crops with high surface sheltering degree inhibit the rhizosphere soil moisture evaporation and increase the soil moisture content. It has strong effects, such as alfalfa in legume green manure, sorghum grass in Japanese grass green mantis and Japanese claw nymph in Japanese green manure, and green thorn and multi-flower magnolia in shrub green manure. From the temperature changes of different green manure varieties on the top soil of the plant rhizosphere, the plant growth is fast, the stems and leaves are lush, and the green manure crops with high surface shade have a significant effect on lowering the topsoil temperature, and the water content of the topsoil in the rhizosphere is more obvious. The negative correlation indicates that the sheltering of stems and leaves has a significant effect on regulating the temperature of the top soil in crop rhizosphere.
