| 摘 要： | 为了给大豆生育后期合理灌溉提供一定的参考依据。试验在2016—2017年采用8个春大豆品种为材料,于收获后用Foss1241测定蛋白质和脂肪含量,并进行产量计算,以此探讨鼓粒期干旱对春大豆品质和产量的影响。结果表明,在鼓粒期干旱条件下,‘黑农37’蛋白质含量下降最为明显,而‘合丰46’变化最小;‘黑农61’脂肪含量升高最为明显,‘绥农29’脂肪含量升高幅度最小;‘黑农65’百粒重下降最为明显,‘黑农45’百粒重下降幅度最小;‘黑农65’产量降低幅度最大,而‘黑农44’、‘黑农37’和‘黑农45’产量降低幅度均较小。本试验表明,鼓粒期干旱会使大豆蛋白质含量下降,脂肪含量升高,百粒重下降,产量明显降低。

Drought Affects Quality and Yield of Spring Soybean at Drum-filling Stage |
| |
| Abstract: | To provide references for rational irrigation on soybean at later growth stage, eight spring soybean varieties were used as materials in the experiment from 2016 to 2017. After harvesting, protein and fat content were measured by Foss 1241, and the yield was calculated to explore the effect of drought at grain filling stage on quality and yield of spring soybean. The results showed that under drought condition at grain filling stage, the protein content of‘Heinong 37’decreased most obviously, while that of‘Hefeng 46’changed least; the fat content of‘Heinong 61’had the most obvious increase, and the fat content of‘Suinong 29’had the least increase; 100- grain weight of‘Heinong 65’had the most obvious decrease and that of‘Heinong 45’ decreased the least;‘Heinong 65’had the greatest reduction in yield, while‘Heinong 44’,‘Heinong 37’and ‘Heinong 45’had the smallest decrease in yield. The experiment indicats that drought at grain filling stage could decrease protein content and 100-grain weight, increase fat content, and decrease yield obviously. |
