摘要
Abstract
[Objective] The research aimed to study the effects of different nitrogen levels on the biological traits and yield per plant of Pennisetum hydrium. [ Method] The biological indices and fresh weight per plant of Pennisetum hydrium at different nitrogen levels after cutting were measured. [Result] The tiller number, effective stem diameter, leaf number, plant height, node number and fresh weight per plant of P. Hydrium were obviously enhanced with the increase of nitrogen level. When nitrogen application amount per pole was more than 40 g or 45 g, these biological characteristics were significantly reduced. [ Conclusion] The optimum fertilizer amount for the growth of Pennisetum hydridum was nitrogen application amount per pole of 45 g and the fresh weight per plant reached its maximum(640. 73 g).关键词
