种植密度对安豆4号农艺性状及产量的影响

Effects of Planting Density on Agronomic Characters and Yield of Soybean Cultivar Andou No.4

为明确大豆新品种安豆4号的适宜种植密度,设置5种不同密度试验。结果表明,密度在18.8万株/hm2时,个体发育健壮,群体生长协调,达到高产的目的,为安豆4号在河南省种植的适宜密度。

In order to determine the optimum planting density of soybean cultivar Andou No.4 in Henan Province, five different densities, 158 000 plants/ha, 173 000 plants/ha, 188 000 plants/ha, 203 000 plants/ha, 218 000 plants/ha were implemented to select the appropriate density. The result indicated that： when soybean was planted at 188 000 plants/ha, both the individual and the population were in the best situation.
