对在民勤沙区栽培的苹果梨、锦丰梨、金冠苹果、民勤小枣、沙枣５种经济树种的蒸腾强度、组织含水率、自然饱和亏、临界饱和亏、束缚水／自由水、水势、持水力、土壤含水率等８项水分生理指标的测定分析表明，这５种经济树种水分生理指标之间，蒸腾强度与水势呈正相关关系。其中，金冠苹果相关系数达到了０．９５５，呈显著正相关关系；锦丰梨相关系数达到了０．９８９，呈极显著正相关关系；并得出了锦丰梨、金冠苹果的蒸腾强度与其他指标间的多元线性回归方程。
The transpiration intensity, tissue moisture content, natural saturation deficit, critical saturation loss, irreducible water / free water of five economic tree species, apple pear, Jinfeng pear, Golden Delicious apple, Minqin jujube and date apple cultivated in the sand area of Minqin, , Water potential, water holding capacity, soil water content and other eight water physiological indicators of the analysis showed that the five economic tree species between the water physiological indicators, transpiration intensity and water potential was positively correlated. Among them, the Golden Delicious apple correlation coefficient reached 0.955, showed a significant positive correlation; Kam Feng pear correlation coefficient reached 0.989, was a significant positive correlation; and Jinfeng pear, Golden Delicious apple transpiration intensity and Multiple linear regression equations among other indicators.
