摘　　要：20世纪90年代中期由于市场经济的驱动,青椒生产效益可观,露地栽种迅猛发展。但耕作制度和栽培技术未能创新,致使病害严重,生产状况日趋衰落。现对造成减产和低产的原因包括气候影响、育苗技术失误、病害严重、栽培管理不当和品种混杂退化进行了分析,并总结出一套新的耕作栽培技术,即培育适龄壮苗,营养钵、营养土块育苗,早期综合防蚜,移栽地的整地、作畦,覆盖地膜,严格选地、轮作倒茬、切忌连作,增加密度、创造良好田间结构,加强田间的管理和及时中耕。The green pepper production benefit was considerable,and plant development was rapid,because of the market economy drive at the middle of 1990＇s.But farming system and planting technology innovation is not enough to result in serious diseases and production status decline.Now,the reasons result in low yield and yield reducing were summarized including climate impact,seedling technique mistakes,disease serious,improper cultivation and management and varietal complexity.Then it analyzed the increasing yield countermeasures such as foster right age strong seedling,nutritional bowl and soil block seedling,early composite controlling aphids,soil preparation of transplanting,covering film,strictly select land,crop rotation,avoiding continuous cropping,increasing density and creating a good field structure,strengthening the field management and intertillage in time.Finally,it concluded a new farming cultivation technology.
