摘要
基于公路劣质边坡的绿化特点,对其生态栽培基质的部分进行基本配方的研究。采用正交试验设计,通过对栽培基质的物理指标、化学指标及其对植物生长效果的测定,选出具有较好保水保肥能力、透水透气性的生态栽培基质配方。结果表明:纤维是影响发芽率和生根率最主要的因素;容重对于种植土的影响最大,且成正比;草炭和纤维能够较好改善土壤通气性;草炭对持水量的影响最大,但不是越多越好;种植土和草炭对酸碱度的影响很显著;种植土是唯一能降低基质中有机质含量的因素。综合指标较优的配方为种植土∶草炭∶蛭石∶纤维=2∶n∶1.5∶2或5∶5∶1.5∶n。
This paper based on the afforestation features of the bad quality road slope studies,the basic prescription of the ecological planting and cultivationmatrix.The orthogonal experiment was used in this paper.The purpose was to find out a sort of prescription which was able to hold water and fertilizer and has the function of allowing ventilation and water.The approach was to determine the physical and chemical index of thematrix as well as its effort on the growth of plants.The result shows that fiber was themost important factor,which can affect the germination and rooting ratio;Bulk Density was themost important factor to the planting soil and was the direct ratio of it;turfy and fiber can improve the ventilation of soil;turfy has themost important effect on the amount in holding water;planting soil and turfy have an obvious effect on themeasure of the acidify or alkalinity of a solution;planting soil was the only factor which can reduce the amount of organicmatter inmatrix.The ratio of a suitable prescription was that planting soil： turfy： vermiculite： fiber was 2∶n∶1.5∶2 or 5∶5∶1.5∶n.
