不同基质配方对蔓性千斤拔漂浮育苗幼苗生长的影响
Effects of Different Formulations of Matrix on Seedling Growth of Flemingia Philippienesis by Floating-seedling-raising
摘要
Abstract
The effect of different matrix formula to the characteristics of growth of the flemingia philippinensis seedlings was studied.Bagasse was used to replace peat soil as the main matrix under the condition of floating-raising-seedling system.The results showed that different formulations of matrix had different effects on the morphological indexes of flemingia philippinensis seedlings.The quality seedling from the matrix formulation A was the best among all the matrix formulations.Compared to those of CK,for the matrix A formulation,plant height decreased 12.7％,the main root length,the first lateral root numbers,dry matter weight per plant and the ratio of root to shoot were increased 10.4％,20.6％,70.3％ and 23.4％,respectively.But there was no significant difference for the leaf numbers.The seedling individual structural indexes of matrix B and C were significant better than those of CK.There was no significant difference in the seedling quality between matrix D and CK.The seedling quality of matrix E was worse than those of the other matrixes.关键词
