摘要
[目的]探讨麻竹叶片对营养元素高效利用的最优肥料配方，为麻竹高产高效栽培和科学施肥提供理论和实践依据。[方法]试验共设4个配方施肥处理，分别是处理①： N－P2 O5－K2 O＝19－7－10；处理②：N－P2 O5－K2 O＝17－8－11；处理③：N－P2 O5－K2 O＝12－12－12；处理④：传统施肥（碳铵），研究不同配方施肥对麻竹叶片营养元素含量的影响。[结果]配方施肥能促进麻竹叶片营养元素的吸收，施肥前后各处理麻竹叶片营养元素含量大小顺序为：处理②、处理①、处理③、施肥前、处理④。[结论]配方施肥处理②的施肥效果最佳，其叶片营养元素含量均高于其他施肥处理，传统施肥处理④的叶片营养元素含量反而比施肥前有所下降。可见，配方施肥具有明显提高麻竹叶片营养元素含量的效果。
Abstract
Objective] The aim was to discuss the optimum fertilizer formula for the efficient utilization of the nutrient elements in the leaves of Dendrocalamus latiflorusfor, to provide a theoretical and practical basis for the high yield and high efficient cultivation and scientific fertiliza-tion.[Method] Four treatments were included in the experiment, including ① N-P2O5 -K2O =19-7-10; ② N-P2O5 -K2O =17-8-11; ③ N-P2 O5 -K2 O =12-12-12; ④ traditional fertilization, ammonium bicarbonate.The effect of different formula fertilization on the nutrient element contents in the leaves of D.latiflorus Munro was studied.[Result] Formula fertilizer could promote the absorption of nu-trient elements in the leaves of D.latiflorus, before and after fertilization, the nutrient element contents in the leaves of each treatment were in order as treatment ② >① >③ >before fertilization >④.[Conclusion] So the formula fertilization of the treatment ② had the best effect, the contents of nutrient elements in leaves were higher than those in other treatments, the content of nutrient elements in leaves of ④treated with traditional fertilization was decreased compared with that before fertilization.So the effect of formula fertilization on the content of nutrient elements in the leaves of D.latfil orus was obviously improved.
