| 摘 要： | 利用济宁市2005年冬季11县市的平均气温、降水等气象资料,并通过对冬后不同生长时段的小麦进行系统调查研究,分析了2005年冬季天气特点及其对冬后小麦生长的影响。整个冬季,前期气温偏高,中后期气温偏低,负积温较常年偏多,使小麦发生了不同程度的主茎冻枯型冻害,致使其苗高增长、单茎绿叶面积衰减、茎秆干重、千粒重增长等差异较大,从而使济宁市小麦平均产量降低,并针对造成小麦冻害的主要原因提出了相应的预防措施和建议。

| Abstract: | The characteristics of winter weather condition in 2005 and its effect on the growth of winter wheat after winter are analyzed on the basis of the winter average air temperature and precipitation data of 2005(December 2004 to February 2005) from 11 counties of Jining,through systemic analysis of the various growth phases of winter wheat.In the entire winter,air temperature was higher at first and became lower in the mid-and late-winter.The negative accumulated temperature was higher than normal,resulting in the freezing injury of wheat stem and consequently the increasing of seedling height,the decreasing of greenery area,and the increasing of stalk net weight and kilo-grain weight,so the average wheat yields in Jining were reduced.The relevant countermeasures and suggestions are proposed aiming at the main causes of wheat freezing damage. |
