【摘要】 采用盆栽试验对不同土壤水分条件下冬小麦幼苗蒸腾及与其影响因子的关系进行了初步研究。结果表明,蒸腾速率和气孔导度均随土壤水分的减少而呈降低趋势;通过逐步回归,获得了不同土壤水分条件下冬小麦幼苗蒸腾速率与其影响因子的最优回归模型。更多还原

【Abstract】 In this paper the transpiration characteristics of winter wheat seedling and the relationship between transpiration rate and influencing factors un-der the different soil droughts were studied.The results showed that transpiration rate and stomata conductance were decreased with the decreasing of the moisture in soil.The regression models of transpiration rate of winter wheat seedling and its influence factors were formed.Meanwhile,some problems in the studies were pointed out and discussed.更多还原
