本文就利用农业气象监测网资料,开展区域性农业气象服务中,作物品种在空间与时间上的差异问题,采用统计学方法,初步评估了不同水稻、小麦品种对产量以及对生育期长短的影响。初步分析表明:品种差异的影响客观存在,尤其对生育期的影响较显著;但开展区域性产量预报服务可不考虑品种因素;做生育期预报时应考虑品种类型的影响。
In this paper, the use of agricultural meteorological monitoring network information to carry out the regional agrometeorological services, crop varieties in space and time differences, the use of statistical methods, a preliminary assessment of different rice, wheat varieties on the yield and the length of the growth period . Preliminary analysis shows that: the impact of species differences objectively exists, especially for the growth period of more significant impact; but to carry out regional yield forecasting services can not take into account the factors of variety; growth period forecast should take into account the impact of the type of species.
