旱地高产小麦光合速率与产量变化的研究

Researches on the photosynthesis rate and Yield in Dry Land Wheat of High Yield

在旱地大田条件下对鲁麦 2 1与D2 7两品种生育后期旗叶与群体光合速率、籽粒灌浆速率及产量变化进行了研究 ,认为旱地小麦要获得高产必须保持开花后高的旗叶与群体光合速率 ,以有利于籽粒灌浆速率维持 。

The researches on the flag leaf and colony photosynthesis rate、and kernel filling rate and yield of wheat variety L21 and D27 have been studied in dry land. The results as follows: gaining high yield must keep higher flag leaf and colony photosynthesis rate after anthesis, highter flag leaf and colony photosynthesis rate will be benefit to keep kernel filling rate andform high yield.
