甘肃中、东部地区春小麦产量潜力研究
|
摘要
根据甘肃中部、东部的气象数据,利用APSIM模型模拟研究区的春小麦产量,分析春小麦产量潜力。结果表明:甘肃中部康乐、临洮等地和甘肃东部泾川、灵台、合水、秦安等地的小麦产量实测值和模拟值误差较小,春小麦产量差较小,产量可提升的空间小;康乐县小麦产量的模拟值与实测值非常接近,小麦生产力接近于极限;定西、渭源、通渭、华亭、环县等地小麦产量实测值和模拟值之间差值较大,有较高的生产潜力。
According to the meteorological data of central and eastern Gansu province,APSIM model was used to simulate the yield of spring wheat in the research area and analyze the potential of the yield of spring wheat in the research area. The results show that the difference between the measured and simulated values of wheat in these regions including Kangle,Lintao,Jingchuan,Lingtai,Heshui and Qin'an is small,the difference in spring wheat yield is small,which means that there is little room for the improvement of wheat yield. The simulated value of wheat yield in Kangle county is very close to the measured value,and the wheat productivity is close to the limit. However,the difference between the measured and simulated values of wheat in Dingxi,Weiyuan,Tongwei,Huating,Huanxian and other regions is wide,which indicates the production potential of these region is high.
