麦蚜是小麦主要害虫之一,其优势种在山东为麦长管蚜[Macrosiphum avenae(Fabriclus)],以为害小麦穗部为主,直接影响着小麦的产量。为正确估计其为害所造成的损失,制订出经济为害损失标准和适合我省条件的化学防治指标,我们于1983～1985年在山东泰安、德州、淄博三地(市)
Wheat aphid is one of the major pests of wheat and its dominant species is Macrosiphum avenae (Fabriclus) in Shandong Province, which is the main wheat ear, which directly affects wheat yield. In order to correctly estimate the damage caused by the damage and formulate the economic damage loss standard and the chemical prevention and control index suitable for the conditions in our province, we set up the chemical prevention and control indexes in three places (Taian, Dezhou, Zibo, Shandong) from 1983 to 1985,

大麦在小春作物中所占比例小,长期以来,人们忽略了对大麦的科学管理,普遍存在对大麦少施肥或不施肥的现象,致使大麦生产发展受到影响。应根据大麦的需肥规律,科学施肥,从而

小麦由低产变高产的主要矛盾,是群体与个体之间发育的矛盾。解决这一矛盾,主要是在栽培措施上采用合理密植、运用肥水促控等手段来加以协调。在生产中常可见到由于盲目施肥
