不同复方基质对蔓性千斤拔漂浮育苗幼苗生长特性的影响
Effect of Different Compound Matrixes on the Growth Characteristics of Flemingia philippinensis Seedlings in Floating-Raising-Seedling System
摘要
Abstract
The sugarcane bagasse was used as the main component to study the effect of different compound matrixes on the growth characteristics of flemingia philippinensis seedlings.The results showed as follows:the plant height,the length of main root,the number of the first lateral root,each dry plant weight and the ratio of root to shoot were significantly influenced,however,the number of leaves was hard-ly influenced.M5 treatment (sugarcane bagasse : perlite : river sand : vermiculite : peat soil=5 : 1.5 :1 : 1 : 1.5) had greater effect on individual morphological indexes of seedlings:the plant height,the length of main root,the number of the first lateral root were almost the same with those in the period of CK,but the number of leaves and each dry plant weight decreased by 7.77% and 15.9%,and the ratio of root to shoot increased by 28.80%;under the treatment of M1(sugarcane bagasse : perlite : slag : peanut shell : peat soil=4 : 1 : 1.5 : 1 : 2.5) and M4 (sugarcane bagasse : perlite : slag : peanut shell : peat soil=5 : 1.5 : 1.5 : 1 : 1),the ratio of root to shoot increased by 23.30% and 16.00% respectively,but the length of main root,each dry plant weight were almost the same with those in the period of CK,and the plant height,the number of leaves,together with the number of the first lateral root were influenced negatively.The effect of M2(sugarcane bagasse : perlite : slag : peanut shell : peat soil=4 : 1.5 :1 : 1.5 : 2) and M3(sugarcane bagasse : perlite : river sand : peat soil=5 : 1 : 1 : 3) treatments were not so good.关键词
