- 摘要:
- 对齐齐哈尔地区种植面积较大的8个高油大豆品种脂肪含量积累动态进行研究。结果表明:在整个生育过程中,随着鼓粒天数的增加,籽粒脂肪积累也逐渐增加。嫩丰17、嫩丰18、嫩丰119生育期较短,籽粒脂肪积累的最高时期在79~85 d;合丰50、合丰47、黑农46、黑农44、黑农41生育期较长,籽粒脂肪积累的最高时期在85~88 d。确定大豆成熟后期脂肪积累的最高时期—最佳收获时期,大豆收获期较成熟期拖后10 d,脂肪含量通常可降低0.5~1.0个百分点,由此得出适期收获在不改变原有品质的基础上,可提高大豆含油量0.5~1.0个百分点。
- Abstract:
- To study the dynamic fat accumulation about eight high-oil soybeans which are growing large area in Qiqihar,the result showed that with the increasing of seed growth days the fat accumulation was also increased.Nenfeng 17,Nenfeng18 and Nenfeng 19 have shorter growth period than Hefeng 50,Hefeng 47,Heinong 46,Heinong 44 and Heinong 41.And for the highest fat accumulation pcriod in the seed,the former is 79~85 days while the latter is 85~88 days.The best period at later maturation when the maximum fat accumulated was confirmed.Then it can help farmer chose the right time to have harvest.It was proved primarily that the best harvest period was 10 days later than maturation,at which period fat content may fall 0.5 to 1 percentage point.Therefore,to harvest at appropriate period basing on not change the soybean germplasm,about 0.5 to 1 percentage point oil content may be enhanced.
