By using the statistical methods of simple and partial correlation, progressive and integral regression, the relationship between the yearly yield per mu of winter wheat and the local meteorological factors including precipitation, temperature and illumination of thirty years(1954—1983) in Xinxiang Region, were studied. The result shows that the total value of the three major meteorological factors during the whole growing period of winter wheat in this region can generally meet the need of the growth of winter...

By using the statistical methods of simple and partial correlation, progressive and integral regression, the relationship between the yearly yield per mu of winter wheat and the local meteorological factors including precipitation, temperature and illumination of thirty years(1954—1983) in Xinxiang Region, were studied. The result shows that the total value of the three major meteorological factors during the whole growing period of winter wheat in this region can generally meet the need of the growth of winter wheat, and the relati- On between supply and demand of the meteorological factors studied is suitable for the growth and development of the winter wheat in most growth stages. The key meteorological elements that cause the yield fluctuation of winter wheat in this region are the temperature in May, the precipitation in Dec., Feb. and May. There is a relatively low probability of reaching the level necessary for high wheat yield, but their effect on the yield of winter wheat varies in good and poor year. Accorcdng to the analysis of the results, some cultivation measures of winter wheat in this region have been suggested.

本文采用简单相关、偏相关、逐步回归和积分回归等统计学分析方法,对新乡地区三十年(1954~1983)冬小麦单产与当地水、温、光等气象要素的关系进行了研究。结果表明,该区冬小麦全生育期内的水、温、光三要素总值基本能满足冬小麦生长发育的需要,且各气象要素在绝大多数时段内与冬小麦生长发育的供求关系比较适宜。影响该区冬小麦产量波动的主要气象因素是五月份温度,十二月、二月和五月份降水,它们的丰产出现概率均较低,但是,它们对冬小麦产量影响大小在丰,欠年存在着一定差异。根据上述研究结果,对该区冬小麦栽培管理措施提出了建议。
