The Relative Change Law of Soil Water Potential in Wheat Growth
The growth of wheat needs enough water, and the soil water potential will have a great impact on the change of soil moisture. Therefore, when analyzing the soil moisture of wheat, it must be based on the changing law of soil water potential. We use the soil moisture meter to measure each The soil moisture content of the region is summarized by statistics to analyze the relative variation of soil moisture.
Soil water potential changes relatively stable. This to a certain extent reflects the amplification mechanism of the effect of soil moisture on the interface, that is, the small changes in the soil water potential, implying major changes in the internal and interfacial water movement processes. This paper generalizes the soil-wheat-atmosphere continuum system to the soil-atmosphere interface of the wheat field with the canopy top as the upper boundary and the surface as the lower boundary, and its thickness is a function of the (green) leaf area index. Through the analysis of the components of soil moisture, leaf area index and energy balance, it was found that:
1. Soil moisture has an important role in inhibiting or accelerating the transport of water and energy perpendicular to the interface. For sensible heat and latent heat transport, soil moisture plays a decisive role. The smaller the soil moisture, the greater the sensible heat flux and the smaller the latent heat flux, and vice versa. The interface thickness only has a greater effect on sensible heat and latent heat transport when soil moisture is small. For soil heat transport, the interface thickness plays a decisive role. The greater the interface thickness is, the smaller the soil heat flux is.
2. The correlation coefficient between soil water potential, leaf water potential and atmospheric water potential at the depth of 60cm is larger than that at other buried depths. The 60cm soil layer is a good indicator layer in the study of the effect of soil moisture on water heat transfer. The effect of soil moisture movement on the interface has an enlargement mechanism, ie, a small change in the soil water potential will cause a large change in the water movement process within the interface and above the interface.
