摘要
为了解不同种类的肥料、肥料配比和用量对菜用大豆农艺性状与产量的影响,进一步筛选合适的肥料种类,优化施肥结构,开展了试验.结果发现,从不同类型的豆粒数量和质量来看,处理 1 表现最优;从总豆荚数、总质量和平均豆荚质量等 3 个指标来看,处理 1 表现最优;百粒重与分枝数、株高与分枝数、百粒重与每公顷产量之间均没有明显的对应关系;处理 4,基肥 300 kg·hm-2(氮磷钾配比为 N 20%、P2 O5 15%、K2 O 10%),追肥 525 kg·hm-2(N 14%、P2 O5 4%、K2 O 22%)产量最大;处理 5,汉枫(氮磷钾配比为 N 22%、P2 O5 10%、K2 O 16%)一次性施 600 kg·hm-2 能得到最大株高;处理 6,好乐耕(氮磷钾配比为 N 13%、P2 O5 6%、K2 O 8%)一次性施肥 1 020 kg·hm-2 能得到最大百粒重.不同厂家的肥料及施肥数量和配比对菜用大豆浙鲜 9 号产量会产生较大的影响.
Abstract
This experiment was conducted to understand the effects of different types of fertilizers,fertilizer ratios,and amount on the agronomic traits and yield of vegetable soybeans,further screening of suitable fertilizer types and optimization of fertilizer structure.The results showed that treatment 1 performed the best in terms of the quantity and quality of different types of bean kernels;From the three indicators of total pod number,total mass,and average pod mass,treatment 1 performed the best;There is no significant correlation between 100 grain weight and the number of branches,plant height and the number of branches,and 100 grain weight and the yield;Treatment 4,with a base fertilizer of 300 kg·hm-2(nitrogen phosphorus potassium ratio of N 20%,P2 O5 15%,K2 O 10%)and topdressing of 525 kg·hm-2(N 14%,P2 O5 4%,K2 O 22%),can achieve maximum yield;Treatment 5,Hanfeng(with a nitrogen phosphorus potassium ratio of N 22%,P2 O5 10%,K2 O 16%)can achieve maximum plant height by applying 600 kg·hm-2 at once;Treatment 6,Haolegeng(nitrogen phosphorus potassium ratio of N 13%,P2 O5 6%,K2 O 8%)can achieve a maximum 100 grain weight by applying 1 020 kg·hm-2 at once.The amount and ratio of fertilizers and fertilizers from different manufacturers will have a significant impact on the yield of vegetable soybean Zhexian 9.
