河北冀东棉区以盐碱地为主,棉花产业在农业生产中占据一定的地位。棉花的可塑性很强,很容易受到气候条件、栽培管理等诸多因素的影响。因此,必须从密度设置、浇水施肥、整枝打杈、化学调控、中耕培土等栽培管理关键环节着手,系统调控,灵活管理,塑造理想群体结构,这些调控措施协调一致才能实现棉花高产早熟优质。一、播种至苗期调控管理措施冀东地区土壤盐碱,春季易受低温阴雨天气影响,对出苗保苗十分不利。因此播种至苗期培
Hebei Jidong cotton area to saline-based, the cotton industry in agricultural production occupy a certain position. Cotton plasticity is very strong, it is vulnerable to climate conditions, cultivation and management and many other factors. Therefore, it is necessary to start from the key aspects of density management, watering and fertilization, pruning and pruning, chemical regulation and control of cultivation and cultivation of soil and other cultivation and management systems, and to regulate and flexibly manage and shape the ideal group structure. Only by coordinating these control measures can we achieve high yield and good quality cotton. First, the sowing to seedling control measures Jidong soil salinity, spring vulnerable to cold and rainy weather, the emergence of seedlings is very negative. So sown to seedling culture
