| Abstract: | The present paper is a study on the regularities of the dynamic changes in the tillering and spike-forming of winter wheat and the quantitative relationship between these regularities and the ecoclimatic conditions inHuanghuai Plain of Henan province, based on a lot of field experiments carried out on various sites in that region. The main research result shows hat the changes in the tillering and spike-forming of the winter wheat in that region have a close relationship with the ecoclimatic factors such as temperature and soil moisture. Their quantitative relationships are as follows: (1) Before the maximum plant population:(2) After the maximum plant population: |
