| Abstract: | By using the principles of statistics and the method of analysis, the effect of meteorological factors on spike grain number of winter wheat in main growth period is analyzed. The relative humidity play much effection during the tiller to jointing. The precipitation play mainly effcetion after the jointing. Turn green-Heading is affected greatly by sunshine time. |
