摘  要:
为了保障粮食生产安全,合理安排农业生产,有效利用地方气候资源,为防灾减灾服务,通过大豆分期播种实验,运用数理统计和气候诊断分析方法,研究了辽西地区大豆的适宜播种期。结果表明:辽宁西部地区春播大豆初始日平均气温为12.0℃,适宜日平均气温为15.0~20.0℃;大豆播种至出苗需要≥10.0℃有效积温最低为109.4℃·d;随着日平均气温的升高,出苗速度加快,当日平均气温在20.0℃以上时,大豆出苗速度最快为7d。辽宁西部地区大豆适宜播种期为4月25日至5月10日,最佳播种期为4月27日至5月5日。该研究结果可为合理安排大豆生产提供科学依据。

摘  要:
In order to ensure the safety of grain production and make the arrangement of agricultural pro-duction reasonable,and serve for disaster prevention and mitigation with effective use of local climate re-sources,this paper uses the mathematical statistics and analysis method of climate diagnosis with soybeansowing experiments and makes a research of the suitable seeding time for soybean in the western liaoningregion. The results show that the average temperature of the spring sowing soy bean at the initial day inwestern Liaoning district is 12.0℃,the average temperature of the suitable day is 15.0~20.0℃;the tempera-ture should be over 10.0℃from the sowing of the soybean to the emergence of seedlings and the lowest ef-fective accumulated temperature should be 109.4℃;with the increase of the daily temperature,the speed ofthe seeding emergence speeds up and when the average temperature at that day is more than 20.0℃,thefastest speed for the seeding emergence is 7 days. The suitable seeding time for soybean in the westerndistrict of Liaoning province is from April 25 to May 10,and the best seeding time is from April 27 toMay 5. The results of this research can provide scientific basis for the reasonable arrangement of soybeanproduction.
