The non-stomatal limitation play dominant role in decline of photosynthesis while relative soil water content is below 65% which could do harm to photosynthesis organ.
当土壤相对含水量低于65 %时，非气孔限制逐渐成为光合下降主导因子，并可能导致光合器官受到损伤。
The desired input parameters were soil physical constants, crop 's developmental date, initial soil water content and daily air temperature, relative humidity and precipitation.
模式所需的输入为初始土壤含水量、土壤物理常数、作物播种期、逐日平均气温、相对湿度和降水量。
On the basis of the experimental data in farmland, a function relationship between the potential evapotranspiration and the relative water content of the soil in the root zone was established.
