木薯氮素营养特性及氮肥施用的研究进展

摘要

Nitrogen nutrition is the key factor influencing growth and development of cassava and determining yield and quality of tubers. By using documentary references, the nitrogen nutrition characteristics of cassava were reviewed from aspects of nitrogen content in the plant,nitrogen absorption, accumulation and allocation,effects of applying nitrogen fertilizer on growth,development,yield and quality.Meanwhile,further questions were proposed .%氮素营养是影响木薯生长发育及决定木薯块茎产量和品质的关键因素。从木薯植株的氮素含量、氮素吸收、积累与分配，施用氮肥对木薯生长发育、产量及品质的影响等方面对木薯氮素营养需求特性进行了综述，并提出有待于进一步研究的问题。
