摘要
2017~2018年在延边州农业科学院试验地对适宜该生态区域的20个大豆品种进行鉴定与分型(类)。根据品种产量潜力和对氮磷钾肥的响应,划分为高效高响应、高效低响应、低效高响应和低效低响应4种类型,并研究了不同类型品种的倒伏情况和农艺性状的差异,旨在鉴定出适宜当地种植且满足不同需求的最佳品种。结果表明:高效高响应品种9个,为生产最佳品种;高效低响应品种3个,为减肥增效首选品种;低效高响应品种6个,可适当选择;低效低响应品种2个,不建议生产应用。低效低响应品种施肥与不施肥条件下均倒伏严重,其他3个类型品种大多表现较轻倒伏症状。相比于低响应品种,高响应品种对氮磷钾肥的高响应主要表现在显著提高株高、节数、分枝数、单株荚重、单株粒重和百粒重。
Twenty soybean varieties suitable for ecological areas were identified and classified from 2017 to 2018 in the experimental field of Yanbian Academy of Agricultural Sciences. According to the yield potential and response to N, P, K fertilizer, the varieties were divided into four types: high efficient with high response(HH), high efficient with low response(HL), low efficient with high response(LH) and low efficient with low response(LL). The lodging situation and agronomic traits of different types of soybean varieties were studied to identify the best varieties suitable for local cultivation and meeting different needs. The results show that: there were nine soybean varieties with HH,which were the best variety for production, three soybean varieties with HL, which were the first choice for reducing weight and increasing efficiency, six soybean varieties with LH could be selected properly, two soybean varieties with LL, which were not recommended for production and application. The lodging of LL varieties was serious under fertilization and no fertilization, and most of the other three types showed light lodging symptoms. When compared with the low response varieties, the high response varieties to N, P, K showed significantly increased plant height,node number, branch number, pod weight per plant, seed weight per plant and 100-grain weight.
