莜麦是一种喜水、喜氮、喜凉、怕热的作物,栽培管理技术要抓好几个环节。一、轮作倒茬莜麦不宜连作。长期连作一是病害多,特别是坚黑穗病,条件适宜的年份往往发病率15%以上;二是杂草多,莜麦幼苗生长缓慢,极易被杂草危害,特别是野生燕麦增多,严重影响莜麦生长。三是费地。莜麦连作,每年消耗同样养分,造成土壤里某些养分极缺。莜麦轮作以豆茬为好,因为豆类作物的根瘤菌可以增加土壤中的氮素,同时豌豆又收获早,土壤休闲时间较长,可积蓄较多的水分。山药茬也是莜麦的较好茬口,秋
Barley is a kind of hi water, hi nitrogen, hi cool, afraid of hot crops, cultivation and management techniques to grasp several aspects. First, crop rotation 莜 wheat should not even make. Long-term continuous cropping is one of the many diseases, especially the smut, suitable for the year conditions are often more than 15% incidence; Second, more weeds, oatmeal seedling growth is slow, vulnerable to weeds, especially wild oats increased, Seriously affect the malting growth. Third, fee.莜 wheat continuous cropping, consume the same nutrients each year, causing some nutrients in the soil scarce.莜 wheat crop stubble is better, because the rhizobium leguminous crops can increase soil nitrogen, while peas harvest early, soil leisure time longer, more water can be accumulated. Yam stubble is also a better stubble oat wheat, autumn
