| Abstract: |
| This article analyses the observed data during the growth period of winter wheat in Xifeng Agricultural Meteorology Experimentation Station. The results show that the climate calefaction makes the whole growth period of winter wheat shortened, especially the over-wintering stage, but the real growing days is not reduced. The climate calefaction causes the seeding stage of winter wheat postponed, and the mature stage brought forward, thereby it is beneficial to prolonging the fallow period of field, to extending the growing period of sequential autumn crop, and to improving the use efficiency of climate resources and the output of per unit acreage. The climate changes affect the climate output of winter wheat with a remarkable periodicity. |
