Abstract
In order to obtain the optimum planting density of summer maize new variety Luoyu No .8 in western region of Henan province , the author studied and analyzed the yield and yield components of this variety under different planting densities . The results indicated that:when planting density increased , the single-plant leaf area of Luoyu No .8 increased first and then de-creased, but its LAI increased continuously .Under the planting density of 75000 plants/hm2 , the population leaf area was at a high level for a long time, which was advantageous to the photosynthesis of leaves .The dry matter weight per plant decreased with the in-crease in planting density .The seed-filling speed of Luoyu No .8 was the highest under 75000 plants/hm2 , and was the lowest un-der 82500 plants/hm2 .Through yield analysis , it was concluded that the theoretical optimum planting density of Luoyu No .8 in western region of Henan was 104483.55 plants/hm2 .关键词
