Abstract
Taking Jindou 30 as materials,by the field test,the effect of planting density on yield and yield components of Jindou 30 was studied . The results showed that planting density had a significant effect on yield components factors ,the difference among the number of branches ,number of pods per plant,grain number per plant and grain weight per plant were significant under different planting density ,and planting density had a significant negative correlation.There was significant difference of Jindou 30 yield under different planting density;150 000~270 000 plants/hm2 planting density range,yield increased with the increasing of the density,density of 270 000 plants/hm2 yield was the highest,up to 2 680.8 kg/hm2.As the density increased to 300 000 plants/hm2,production reduced.关键词
