土壤蒸发是受气候、作物、土壤的综合影响,特别自然降水的时间、数量不均,造成土壤湿度无规则分布,给土壤蒸发分析造成了困难。而土壤水分运动以土壤热力为运载条件,热力扩散又有年波动变化,使墒情分析更复杂。本文通过力平衡和波函数求解,综合气候、作物、土壤影响,推导出土壤蒸发模式,用于墒情测报。经历史资料和大田试验比较,它具
Evaporation of soil is affected by the combined effects of climate, crop and soil. In particular, the time and amount of natural precipitation are uneven, resulting in irregular distribution of soil moisture, which makes it difficult to analyze soil evaporation. The soil moisture movement is carried by soil heat, and the thermal diffusivities change again and again in the year, making the analysis of soil moisture content more complicated. In this paper, the solution of soil evaporation is deduced by means of force balance and wave function, and the effects of climate, crops and soil are summarized. After the historical data and field trials, it has
