It could be seen from Table 3 that with the planting density of Nengsi 1 increasing from 75 000/hm2to 525 300 plants/hm2,the fresh weight per plant decreased from 602.74 to 79.73 g/plant,and the dry weight per plant decreased from 135.90 to 18.25g/plant.The differences reached the very significant level,indicating that the planting density had a significant effect on the productivity of single plant.Nengsi 1 had the highest productivity under the planting density of 75 000/hm2(Fig.1).Under the planting density of 75 000/hm2,its fresh weight per plant(602.74 g/plant)increased by 42.41%-86.77%compared with other planting densities,and its dry weight per plant(135.90g/plant)increased by 41.79%-86.58%compared with other planting density,exhibiting very significant differences.The planting density,225 000 plants/hm2produced a middle productivity.Under the planting density of 225 000 plants/hm2,the fresh weight and dry weight per plant were 347.12 and 79.11g/plant,respectively.The fresh weight per plant decreased by73.64%compared with the planting density of 75 000/hm2,but increased by 48.35%and 77.03%compared with the planting densities of 375 000 and 525 300 plants/hm2,respectively,with very significant differences.The dry weight per plant decreased by71.79%compared with the planting density of 75 000/hm2,but increased by 49.74%and 76.94%compared with the planting densities of 375 000 and 525 300 plants/hm2,respectively,with very significant differences.Under the planting density of 525 300plants/hm2,the productivity was the lowest.Specificity,the fresh weight and dry weight per plant were 79.73 and 18.25 g/plant,respectively,and compared with fresh weight and dry weights under other planting densities,the value decreased remarkably,with very significant differences.The results showed that with the planting density increasing,the population competitiveness of Nengsi 1 increased,which inhibited the yield increasing potential of single sweet sorghum plant,resulting in reduced plant productivity.
