摘要
科学施肥是提高马铃薯产量和品质的重要保障。目前,生产过程中人们只注重大量元素的施用,而忽略了中微量元素。与大量元素重要性相比,中微量元素同样影响马铃薯的生长发育,尤其对马铃薯块茎品质及植株抗逆性的提升具有重要作用。为明确大量元素氮、磷、钾,中量元素钙、镁、硫,微量元素硼、锌、锰、铜、铁、钼、氯对马铃薯生长发育、产量构成及块茎品质的影响,文章综述了马铃薯生育期内对各营养元素的需求量以及其对马铃薯地上部生长、根系发育、产量和品质形成的重要调控作用,同时对中微量营养元素施用方式进行比较,以期为马铃薯的复合肥产品创新及其养分高效利用提供理论依据。
Scientific fertilizer application is an important guarantee to improve potato yield and quality.At present,however,more attentions are focused on the application of macro nutrients than second macro nutrients and micro nutrients.Compared with the importance of macro nutrients,second macro nutrients and micro nutrients also play important roles in potato growth and development,especially for both potato tuber quality and plant stress tolerance.In order to clarify the influence of macro nutrients nitrogen(N),phosphorus(P)and potassium(K),the second macro nutrients calcium(Ca),magnesium(Mg)and sulphur(S),and micro nutrients boron(B),zinc(Zn),manganese(Mn),copper(Cu),iron(Fe),molybdenum(Mo)and chlorine(Cl)on the growth and development of potato,and further improve the yield and quality of potato tuber,the demand characteristic of these essential nutrients in potato plant,as well as the regulation of aboveground growth,root development,and yield and quality formation of potato tuber by essential nutrients were reviewed.At the same time,the application methods of the second macro nutrients and micro nutrients were compared.These would provide a scientific basis for the innovation of compound fertilizer for potato to achieve high quality and efficient production.
