| Abstract: | The study on group physiological indexes of new maize variety Luoyu 7 showed that the suitable planting density was 60000 plants/ha.Under the suitable density,the development dynamic of group leaf area index was reasonable,with "rapid increase in early stage,steady in mid stage and slow decrease in late stage" characteristics.In silking stage,the biggest leaf area index reached 5.32,with the stable phase more than 20 days,and the leaf area index was 2.75 at maturing stage.The total photosynthetic potential was 325.67×104(m2·d)/ha.The net assimilation rate during the whole stages was 7.76g/(m2·d) in average.The dry matter accumulation quantity was 23438.9 kg/ha,and the accumulation quantity in silking stage accounted for 60%.The group growth rate was 231.1kg/(ha·d).The grain filling rate was always at a high level,and late filling lasted for a long time,with a high strength.Its final production reached 12028.4kg/ha. |
