以玉米品种四密 2 1为材料 ,通过土柱模拟试验研究了有机无机肥料配合施用对玉米根系的影响。结果表明 :有机无机肥料配合施用 ,提高了玉米各土层特别是中、下层根系干重和比率 ;增加根系伤流量 ;延缓根系活力下降 ;降低根系 MDA含量 ;提高根系 SOD活性。所以能够延缓玉米根系器官的衰老 ,从而使玉米产量提高
The effect of organic-inorganic fertilizers on the root system of maize was studied by soil column simulation test using four corn varieties 21 as material. The results showed that the combination of organic and inorganic fertilizers increased the dry weight and the ratio of roots in all soil layers, especially the middle and lower layers of maize. Increased the root trauma, delayed the decline of root activity, decreased the content of MDA and increased the activity of SOD. It can delay the aging of corn root organs, so that corn yield increased
