摘要
氮是马铃薯生长发育必需的营养元素之一,在马铃薯生长发育过程中发挥着重要作用,同时也是决定马铃薯块茎产量和品质的关键因素。马铃薯生长发育过程中对氮的需要量大,必须加以补充才能满足其正常生长需求。研究和了解马铃薯氮素营养特性,是马铃薯生产合理施用氮肥的前提和基础。综合相关文献资料,归纳马铃薯植株的氮素含量、氮素吸收速率、氮素积累及氮素分配等规律,并概述施用氮肥对马铃薯光合作用、生长发育、产量及品质的影响,提出有待于进一步研究的问题,以期为马铃薯氮素营养的进一步研究和合理施用氮肥提供参考。
Nitrogen is an essential element for potato, which plays an important role in growth and development, yield and quality of potato. Nitrogen is required in large quantity for potato growth and development, but generally lack in the soil, and has to be applied to meet the needs for its normal growth. Study the nitrogen nutrition characteristics is the prerequisite and basis for nitrogen fertilizer rational application of potato production. In order to provide a reference for nitrogen nutrition further research and nitrogen fertilizer rational application of potato, the nitrogen nutrition characteristic of potato was summarized according to some relevant literature in this article, which included the nitrogen content, absorption rate, accumulation and distribution of potato plant. Moreover, the effects of nitrogen fertilizer application on photosynthesis, growth and development, yield and quality of potato were introduced. Finally, the further research topics of nitrogen nutrition in potato were also proposed.
