摘要
为提高土地利用效率,筛选适宜长沙地区油菜收后种植大豆品种,文章以15个大豆品种为研究对象进行夏大豆引种试验。结果表明,华春1号与华春5号播后生育期分别较对照华春21(CK)延长10 d和35 d,属迟熟品种;六月黄生育期较对照华春21(CK)缩短13 d,属早熟品种;其余参试品生育期与对照华春21(CK)相较相差2~4 d,均为中熟品种。14个品种中7个品种(会理大豆4、华春1号、扬州绿大豆、中黄13、南农57、圣豆3号和中黄39)产量均高于对照华春21(CK)。其中华春1号产量最高、生育期较长,会理大豆4抗倒伏性差,圣豆3号抗病虫害能力弱,南农57不抗倒伏、抗虫害能力弱。综合各品种生育期、产量、农艺性状及田间抗病虫害表现,扬州绿大豆和中黄13产量高、生育期适中、抗性强,适宜长沙地区引种种植。
To improve land use efficiency and screen soybean varieties suitable for planting after rapeseed harvest in the Changsha area,this study conducted a summer soybean introduction trial with 15 soybean varieties.The results indicated that the growth periods of Huachun 1 and Huachun 5 after sowing were extended by 10 days and 35 days,respectively,compared to the control Huachun 21(CK),making them late-maturing varieties.The growth period of Liuyuehuang was shortened by 13 days compared to the control Huachun 21(CK),making it an early-maturing variety.The growth periods of the other tested varieties differed by 2-4 days compared to the control Huachun 21(CK),all of which were classified as mid-maturing varieties.Among 14 varieties,seven(Huilidadou 4,Huachun 1,Yangzhoulvdadou,Zhonghuang 13,Nannong 57,Shengdou 3,and Zhonghuang 39)yielded higher than Huachun 21(CK).Huachun 1 had the highest yield but a longer growth period;Huilidadou 4 showed poor lodging resistance;Shengdou 3 demonstrated weak disease and pest resistance;Nannong 57 lacked lodging resistance and had weak pest resistance.Comprehensive analysis of growth period,yield,agronomic traits,and field disease and pest resistance indicated that Yangzhoulvdadou and Zhonghuang 13 with high yields,moderate growth periods,and strong resistance,which were suitable for introduction and cultivation in Changsha.
