Abstract: Through an analysis on days from sowing to physiological jointing and temperature-light factors of spring,facultative and winter wheat sowed in autumn and spring,it is found that,to spring varieties, relativehigher temperature in early growing stage may shorten the days from sowing to physiological jointing; facultative wheat varieties need more than 15 days low temperature below 8 ℃ during early stage, after which, relativehigher temperature may also shorten the days from sowing to physiological jointing; and winter varieties, during early developing stage, need relative lower temperature and more days of low temperature. The results suggest that facultative varietieshave broad prospects of utilization and use value inhenan Province; Spring varieties should not be sowed too early.
