Abstract
The effect of different plant density on agronomic traits and yield of maize Xianyu 335 and Zhengdan 958 and Xingken 3 was studied by field experiment under Daqing ecological environment conditions. The result showed that the best plant density for Zhengdan 958 was 67 500 to 78 750 plants·hm-2 and the best plant density for Xianyu 335 and Xingken 3 was 56 250 to 67 500 plants·hm-2. Grey relational analysis between agricultural characters of maize ranked as follows:1 000 grain weight>ear diameter>ear height>stem diameter>kernel row number>ear length>kernel number per row>plant height>barren ear tip length>lodging resistance>empty straw rate>double ear percentage.关键词
