Research on nitrogen circulation and management of bamboo: a review

Abstract

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, nitrogen 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. ［Ch, 52 ref.］
