【Abstract】 A study on biological characters of different Cultivation in winte wheat was conducted inmiddle region of Shanxi. The results showed that film-muiching and bunch-seeding cultivation hassignificant yield-increasing and wate-saving effects on winter wheat. Comparing with conventionalcultivations, this cultivation could increase 24.76% of yield and 4.95kg/mm hm2 of water efficdricy,and decrease 81.84mm of water consumption. All physiologic active indices were higher than control andwheat development period had been advanced by 7 days.更多还原
