摘要
竹林是森林资源之一,不仅具有重要的经济价值,还具有保持土壤、涵养水源、固碳释氧等重要的生态服务功能。竹林培育越来越受到重视。施肥是竹林丰产培育的重要经营措施,其中,氮素是竹子生长发育的主要养分限制元素,竹林氮素输入尤为重要。为了给竹林氮素输入的技术研究及其应用提供参考,综述了竹子氮素营养诊断、竹林氮素平衡、竹子氮素吸收与利用、竹林氮素输入的环境行为及影响等方面的研究现状,提出了竹林氮素循环机制、氮素形态对竹子生长发育的影响、基于竹笋质量安全的竹林土壤硝化抑制、基于环境安全的氮素补充以及竹林氮素控释专用肥研制与应用等重点研究方向。
As one of forest resources, bamboo forest not only has important economic values but also provides important ecosystem services including soil conservation, water conservation, carbon fixation and oxygen release. Bamboo cultivation has been a focus of research in recent years. Fertilizing is an important measure to improve bamboo cultivation. As one of the major factors affecting the growth of bamboo, nitrogen has great influences on the growth and development of bamboo. In order to provide scientific theoretical basis for bamboo nitrogen input, this paper summarized nutrient diagnosis of bamboo, nitrogen balance of bamboo, rlitrogen absorption and utilization of bamboo, environmental impacts on bamboo nitrogen, and put forward the following focus areas for further research on bamboo nitrogen： nitrogen cycling of bamboo, the influence of nitrogen forms on bamboo growth, bamboo soil nitrification inhibitors based on the quality assurance of the bamboo shoots, environmental safety based nitrogen input, and development and application of exclusive controlled-release fertilizer of bamboo nitrogen.
