冬小麦早熟能调节各作物间争水、争劳力、争机力的矛盾;在新疆,小麦早熟还能避开干热风危害.因此,选育早熟丰产的冬小麦品种,是小麦育种者和广大农民群众的共同愿望.选育早熟冬小麦品种有两条途径,一是缩短其前期营养生长的天数(即出苗至抽穗日数),二是加快其灌浆速度.我们认为,第一个途径行之有效.为探讨这一问题,我们将石河子地区农科所、五家渠农六师农科所、奎屯农七师农科所及阿克苏农一师农科
The precocious winter wheat can regulate the conflicts between competing crops, competing for labor and competing for power. In Xinjiang, the precocious wheat can avoid the harm of dry-hot wind, therefore, the early-maturing and high-yielding winter wheat is the breeder of wheat breeder and farmer .There are two ways to breed early-maturing winter wheat varieties: one is to shorten the number of days of vegetative growth in the early stage (that is, the number of days from emergence to heading) and the second is to speed up the filling rate .We think the first way is effective. To explore this issue, we will Shihezi Agricultural Science Institute, Wuqu Drainage Sixth Division of Agricultural Sciences, Agricultural Division Kuytunong seven division and Akesu agricultural division of agriculture
