通过对优质大豆良种大豆巨人、中黄13与当地种植的通农8号进行春播和夏播比较试验表明:大豆巨人、中黄13春播比当地种植的通农8号分别增产1038kg/hm2、972kg/hm2,夏播比当地种植的通农8号分别增产775kg/hm2、655kg/hm2;主要农艺性状、生长势及抗性均优于当地种植的通农8号,为品种的更新换代提供科学依据。 Compared with the spring sowing and summer sowing of high-quality soya bean soybean giant, Zhonghuang 13 and locally-grown Tongnong 8, the results showed that the spring sowing of soybean giant and Zhonghuang 13 increased 1038kg / hm2 and 972kg respectively compared with the local planting Tongnong 8 / hm2, respectively. The yield of 775kg / hm2,655kg / hm2 was higher than that of Tongnong 8, which was planted in summer. The main agronomic traits, growth vigor and resistance were better than that of Tongnong 8, which was planted locally. in accordance with.
