春小麦缺水敏感指数出现负值的生理机制研究

THE PHYSIOLOGICAL PERSPECTIVE OF NEGATIVE WATER SENSITIVE INDEX VALUES OF SPRING WHEAT

本文从作物生理生化的角度,阐述了春小麦早期轻度土壤、水分亏缺,有提高产量的作用。因此而导致在运用作物水分生产函数时敏感指数(λ_i)出现负值。

The author has presented to physiological and biochemical perspectives that water deficiency during the early stage is beneficial to the increasing of spring wheat's yield, as the reason of the negative values of the water sensitive index in the calculation concerning the crop response.
