摘  要:
:1996~ 1998年 ,在大田生产条件下 ,就施肥水平对小麦群体根系活性、延缓旗叶衰老及籽粒产量的影响进行了比较研究。结果表明 ,土壤肥力和施肥水平对小麦的群体根系活性有显著的调控作用 ,土壤肥力高则根系活性强。施肥可明显促进小麦群体根系活性的提高 ,延缓旗叶衰老 (增加叶绿素含量 ,提高光合速率 ,增强 SOD和 POD活性 ,降低 MDA含量 ) ,显著提高小麦籽粒产量 ,其中有机无机肥配施效果更佳

摘  要:
Soil fertility and levels of applying fertilizer significantly regulated the mass root activity of wheat. With the increase of soil fertility, the mass root activity of wheat became stronger and stronger. Applying fertilizer could obviously improve the mass root activity, prolong the senescence of the flag leaf (by increasing the chlorophyll content, improving the rate of photosynthesis, enhancing the activity of SOD and POD, and loweringthe content of MDA), and improve the grain yield significantly than that of CK. The combination of organic manure and non organic fertilizer was the better applying method among the levels.
