摘要
针对周口小麦生产连年出现中产徘徊的问题 ,研究了小麦中产到高产过程中三要素变化特点 ,相对贡献及主攻目标。关键技术是一推 (推广高产、抗病、抗灾新品种 ) ;二控 (控播量、控群体 ) ;三增 (增穗、增粒、增重 ) ;四防 (防倒、防病、防虫、防灾害性气候 ) ;五改 (改重氮轻磷不施钾为稳氮增磷补钾优化配方施肥 ,改高产病虫害的应急防治为常规性防治、改 2 0 cm土耧大播量为 2 3cm机播、改灌麦黄水为早浇孕穗灌浆水、改冬春追肥为起身拔节追肥 )
Directed against the problem that fluctuation of middle output in succession years, appeared in the wheat production in Zhoukou, the changing feature of three factors in the process of wheat's middle output to high output, relative contribution and main goal of attack were studied. The following are the key technologies: first is popularization, second are controls, third are increases, fourth are prevention, fifth are changes.
