摘  要:
以不同品种甜秆饲用杂交高粱为研究材料,分析它们在不同种植密度下的生长发育动态,结果表明,不同种植密度影响高粱的生长发育,种植密度小的生长发育较快;不同品种比较发现,甜高粱杂交种比甜高粱生长发育速度快,具体表现为可见叶、展开叶发生速度较快,株高较高;从产生分蘖数的角度看,21A×126-524产生的分蘖数最多;从叶面积指数来看,甜高粱叶面积指数最大。经形态指标比较,得出其在不同密度下的生长发育规律,为饲用杂交甜高粱的合理种植提供理论依据。

摘  要:
Different kinds of sweet forage sorghum as research material,this paper analysied their growth dynamic in different planting density.We obtain the growth and development pattern of plant in a different planting density to povide theoretical basis for sweet sorghum reasonable planting.The results showed that: Sorghum planting density affected the growth and development and sorghum having small planting density could growrapidly;Sweet sorghum hybrid grewfast than sweet sorghum,namely,the hybrid had faster visible leaves and expand leaves,and higher plant height.On view of the tiller number,21A×126-524 had the most tillers.On viewof the leaf area index,sweet sorghum had the maximum leaf area index
