冬小麦能否安全越冬,是决定产量高低的关键。越冬能力的强弱,不仅取决于作物本身的品种特性,还与栽培措施和当年气候有关。因此,如何做到适期播种,是提高冬小麦越冬能力的重要环节。河西地区冬小麦最适播种期在什么时间?根据什么来确定这个最适播种期?是大家关心的两个重要议题。一九七四年度,我们对此专门布设了试验。
Winter wheat can be safe winter, is the key to determine the level of output. The strength of winter ability, not only depends on the characteristics of the crop itself, but also with the cultivation measures and the current climate.
