| Abstract: |
| According to the result of observation and parallel analysis of meteorological materials of the farmland test,with the climate warming,the over-growing phenomenon of wheat before winter is obvious and each growing stage in spring gets earlier notably,and arid calamity takes place frequently in the Yuan area of east Gansu Province.In the maize growth course,most puberty stages turn a trend of advancing and shortening notably during the development,and the spring drought and drought in early summer are of serious harm.Under the circumstances of climate warming,in order to avoid the influence of unfavorable climate factors and increase the yield of crops,it is necessary to readjust sowing and harvesting time of crops,which can improve the sowing quality and prevent effectively the winter wheat from over-growing before winter and relieve the influence of drought in spring. |
