| 摘 要： | 本文运用土壤水势能理论,研究了柑树根区土壤水分交换,从动态角度探讨了土壤水分储量的变化、水量均衡,从而建立了由土壤负压资料推算果树耗水量的通用模型——动态均衡法。初步研究表明,动态均衡法相对传统的水量平衡法。考虑的水量均衡要素更全面,计算结果更接近实际。

| Abstract: | This paper presented the soil water balance, water exchange between fruit free root system and change of soil water storage in root zone of the citrus from dynamic viewpoint and provided a general model——Dynamic Equilibrium Method (DEM) for estimating the Evapotranspiration (ET) of fruit trees based on the soil water potential energy theory. A calculated example of water requirement of citrus by using DEM was presented. The intensity of ET influnced by weather condition, root density and different space position was also discussed. Investigation showed that DEM was reasonable. |
