一是以“肥”补迟迟播大麦冬前苗子生长弱,叶片数少,次生根条数明显减少。据调查,11月6日播种的大麦,冬前单株次生根有5～10条,11月21日播种的大麦,冬前单株次生根只1～2条,甚至没有次生根。根系少,吸收能力差,只有增施肥料,才能满足大麦生长发育对养分的需求。增肥要以增施基肥和增施速效性肥料为主。迟播大麦一般应亩施优质发酵的猪、牛栏圈肥2500～3000公斤,过磷酸钙40～50公斤,氮素化肥
First, the “fat ” late delayed late sowing of barley seedling growth is weak, fewer leaves, the number of secondary roots significantly reduced. According to the survey, barley planted on November 6 is that there are 5 to 10 secondary roots per plant before winter, barley planted on November 21, and 1 to 2 secondary roots per plant before winter, even without secondary roots. Less roots, poor absorption capacity, only by increasing fertilization, to meet the growth and development of barley needs of nutrients. Fertilizer to increase base fertilizer and increasing fast-acting fertilizer. Delayed sowing of barley should generally be applied to high-quality fermented pigs, cattle pen circle fertilizer 2500 ~ 3000 kg, superphosphate 40 ~ 50 kg, nitrogen fertilizer
