密度和施肥量对不同分枝类型大豆产量的影响
Effect of Density and Fertilizer Amount on Yield of Different Branching Types of Soybeans
摘要
Abstract
The effect of planting density and fertilizer level on different branching soybeans were studied by the means of a split plot experiment. Three soybean lines ( few-branched Dong-8175, mid-branched Dong-03-2176, multi-branched Dong-0331),four planting densities(1.0,1.5,2.0 and 2. 4 × 105 plant· ha-1') and four fertilizing amounts(300,500,700 and 900 kg·ha-1 )were included in this study. The results showed that the maximum of leaf area index ( LAI)of three lines appeared in the high density (2. 4 × 10 5 plant· ha-1 )and high fertilizer(900 kg·ha-1 ) combination in R4 stage four mid-branched Dong-03-2176, the highest yield was obtained at te planting density of 2.0 × 105 -3.0 × 105 plant·ha-1 with fertilization of 700 -900 kg·ha-1 ;for multi-branched Dong-0331 ,the highest yield was achieved at planting density of 2. 0 × 10 5 plants·ha-1 and fertilization rate of 900 kg·ha-1.关键词
