不同灌水处理对春小麦水分利用率和光合速率的影响
Effects of differenct irrigation mode on WUE and Pn of spring wheat
摘要
Abstract
Study on water use efficiency (WUE)and photosynthetic rate(Pn) of growth duration change and diurnal change of grain filling stage in Spring wheat, Ningchun NO. 4, the results showed that WUE,Pn, Tr respond different under different water measure, WUE, Pn and Tr all showed 2 peaks on growth duration change and diurnal change of grain filling stage. Extremes were happened WUE of A before procreate prophase, WUE of D after procreate prophase, Pn ,Tr would be dropped out with water shortage at any time, WUE were improved rapidly after sunrise, WUE of D were the tiptop in a. m, WUE of C were the opposition. The eorrelativity results showed that prominent positive correlation on WUE with Pn, prominent negative correlation on Tr with Gs. WUE and Pn should be improved through timing irrigation.关键词
