摘要:
以氮、磷、钾、硫、钙及微肥对花生的生理作用与影响为切入点,阐述了施肥对花生生理特性、产量及品质的影响,分析了花生生长与科学施肥之间的关系,并从施肥技术、肥料品种、花生育种、耕作制度等4个方面提出花生施肥研究的主要技术难点以及今后主要的攻关方向。就施肥技术而言,要着力提升精准水平,科学合理地施用肥料;就肥料品种而言,要努力实现优化配套,注重新型肥料的开发;就花生育种而言,要关注多样化筛选,培育高优花生新品种;就耕作制度而言,要因地制宜的改革,优化当地的耕作制度。

Abstract:
This paper reviews the effects of N,P,K and micronutrients on peanut's physiological characteristics,yield and quality.It also disscusses the relationship between biotechnology and fertilization,as well as current issues and directions for future studies in the areas of fertilizing technique,fertilizers,breeding and cropping systems.In the area of fertilizing,scientific applications should be emphysized for future studies.New and existing fertilizers applied should be scrutinized with careful evaluation.In the breeding of peanuts,diversification of selection and search for new varieties should be focussed.On the development of cropping systems,the environmental and ecological conditions and requirements of a specific locality should be considered with high priority.
