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。
Using vegetable soybean Soybeans 20 as the material, the effects of fertilization types and planting densities on the yield and related agronomic characters of vegetable were studied under two-factor completely randomized block experiments. The results showed that the type of fertilization, planting density and the interaction between the two had a significant impact on the yield of vegetable soybean fresh soybean 20, with N-P2O5-K2O being 55-70-50 kg · hm-2, The yield and yield of fresh pods reached 9 045.11 kg · hm-2 with 50% urea and 50% resin-coated urea at the optimum planting density of 300 000 hm-2. Vegetable plant height and effective pods per plant have a significant impact, while the number of branches, the number of main stems and fresh weight per 100 grain weight is not obvious.
