【摘要】 以菜用大豆苏鲜豆20为材料,采用二因素完全随机区组试验,在大田条件下研究了施肥类型和种植密度对菜用大豆产量及相关农艺性状的影响。结果表明:施肥类型、种植密度以及二者的互作均显著影响菜用大豆苏鲜豆20的产量,在N-P2O5-K2O施入量为55-70-50 kg·hm-2,且氮肥组成为50%普通尿素和50%树脂包膜尿素,种植密度30万株·hm-2的最佳施肥与密度组合下,鲜荚产量达到9 045.11 kg·hm-2,施肥类型和种植密度对菜用大豆的株高和单株有效荚数有显著影响,而对分枝数、主茎节数和鲜百粒重影响不明显。更多还原

【Abstract】 Under the field experiment conditions,vegetable soybean variety Suxiandou No.20 was chosen to evaluate the effect of different cultural factors(fertilizer levels and planting densities)on yield and agronomic traits using randomized complete block design.The results showed as follows:the fresh yield of Suxiandou No.20 significantly different under different fertilizer levels,planting densities and their interaction.The highest yield in this experiment appeared in treatment with fertilizer level of PU50%+PCU50% and density of 3.0×105 plants·ha-1,its fresh pod yield could reach 9 045.11 kg·ha-1.Different fertilizer levels and planting densities had great influence on plant height and effective pods per plant,while branches,node number and 100-fresh grain weight were less influenced by different cultural factors.更多还原
