Effects of Seed Coating Agent with Different Components on Seedling Quality and Yield of Maize

大田试验条件下,以郑单958为试验材料,探讨了5种种衣剂对玉米苗期素质及产量的影响,结果表明:9%毒死蜱.烯唑醇种衣剂+悬浮性伴侣能提高夏玉米苗期的叶绿素含量、光合速率、苗期素质,促进生长,同时可降低玉米株高和穗位高,比其他处理增产2.26%～12.74%。

Under the field test condition,taking Zhengdan 958 as test material,the effects of 5 kinds of seed coating agents with different components on the seedling quality and yield of maize were studied.The results showed as follows： in comparison with other treatments,the treatment of 9% Chlorpyrifos · Diniconazole seed coating agent plus suspensive partner could increase the chlorophyll content and photosynthetic rate of maize seedlings,improve the seedling quality,promote the growth of maize plants,decrease the plant height and ear height of maize,and finally increase maize yield by 2.26%~12.74%.
