| Abstract: | According to the data of wheat field experiments,
production demonstractionand meteorlogy for many years,the standardS of pre-winter vigorous
seedlings were pro-posed;The tillering habit,populatoin developmemts,dry matter accumulation
and yield for-mation were analysed;the importance and biological mechanism of pre-winter
vigorousseedlings in higher yield and yield formatoin were discussed.Pre-winter vigorous
seedlingshave vigorous individual seedlings,suitable population,high percentage of fertile
tillers,fastnutrient and dry matter accumulation,more effective ears and plump grains.The
growingtechnigues for vigorous seedlings were discussed. |
