风对科尔沁地区几种常见作物幼苗光合、蒸腾特性的影响
Impact of wind on seedling's photosynthesis and transpiration of several common crops in Horqin Sandy Land
摘要
Abstract
A portable wind tunnel and a Li-6400 system were used to study the effects of different wind velocity (4 and 8 m · s-1) and blowing duration (0, 30, 60, 90, and 120 min) on the net photosynthetic rate ( Pn) , stomatal conductance ( Gs ) , and transpiration rate ( Ts ) of Zea mays , Triticum aestivum, Glycine max , and Vigna radiata in Horqin Sandy Land where strong wind in spring often hurts plants. With increasing wind velocity and blowing duration, the Pn and Gs of test crops all had a significant decrease. The Pn and Gs at wind velocity 4 m · s-1 decreased by 3. 3％ -74. 4％ and 10. 9％ -51. 3％ , and at wind velocity 8 m · s-1 decreased by 30. 8％ - 81. 0％ and 48. 3％ -88. 0％ , respectively, compared with the control. Except for Triticum aesti vun, the Ts of the other three crops under wind blowing increased, and the increment was larger at wind velocity 4 m · s-1 than at 8 m · s-1. Wind-blowing decreased the water use efficiency of the four crops, and thus, increased the dryness of the crops.关键词
