日前,农业部小麦专家指导组发布了《2013年冬小麦春季田间管理技术意见》。《意见》显示:目前小麦由南向北陆续进入返青、起身、拔节期。总的看,今年北方冬麦区苗情基础较好,但黄淮南部和长江中下游部分地区晚播麦田冬前生长量不足,群体偏少、苗龄偏小、个体偏弱;西北部分地区墒情不足,旱象显现;小麦条锈病核心越夏区菌源基数大,有加重发生可能;冬前杂草滋生,春季防除难度大。 Recently, the steering group of wheat experts from the Ministry of Agriculture issued the “2013 Winter Wheat Field Management Technical Opinion.” “Opinion” shows: At present, wheat from south to north one after another into the green, get up, jointing period. In general, the winter seedlings in northern China have a good seedling basis this year, but late winter wheat fields in southern Huanghuai and parts of the middle and lower reaches of the Yangtze River have less winter growth, with less population, younger seedlings, and weaker individuals. In some areas in northwest China, Lack of soil moisture, drought phenomenon; the core of wheat stripe rust summer more bacterial base, there may be aggravating; weeds breeding before winter, spring difficult to control.
