摘    要:应用二次多项式逐步回归方法构建了不同营养元素对狭叶仙鹤藓的植株高度和植株数量的影响方程,并定量研究了不同元素对狭叶仙鹤藓的生长情况影响.结果表明,N和Ca2+和适量的Mg2+能够在狭叶仙鹤藓的生长中起到促进作用;而K+对狭叶仙鹤藓的植株高度会产生不利影响,适量的K+能够促进狭叶仙鹤藓的植株数量.

关 键 词:狭叶仙鹤藓  二次多项式逐步回归  营养元素  Benecke培养基

Abstract:The quadratic polynomial stepwise regression method was used to build the equation which indicated the impact of different nutrients on the plant height and the total number of plants of Atrichum angustatum(Brid.) B.S.G.by quantitative study of the regression equation.The results show that N and Ca2+ and an appropriate amount of Mg2+ could promote the growth of this moss while K+ has a bad impact on the plant height and an appropriate amount of K+ could increase the total number of plants.
Keywords:Atrichum angustatum ( Brid  ) B  S  G  quadratic polynomial stepwise regression  nutrient elements  Benecke culture
