摘要: 绿化植物在种植过程中,栽培基质对其生长影响很大,因此筛选出供肥能力强、pH和EC值都适合绿化植物生长的基质非常重要。本研究选用羽叶茑萝作为供试绿化植物,利用潮土、泥炭和蛭石组成5种不同的栽培基质配方,研究不同栽培基质在羽叶茑萝生长中有效养分的变化情况,并对不同栽培基质中羽叶茑萝的生长情况及壮苗指数进行分析。结果表明:“潮土50%+泥炭30%+ 蛭石20%”和“潮土40%+泥炭60%”栽培基质供应氮磷钾的能力较强,且持久稳定,pH和EC值也适于羽叶茑萝生长,幼苗的株高、茎粗及干重较高,壮苗指数大。上述两种基质均可作为羽叶茑萝的栽培基质。

Abstract: In the process of planting green plants, cultivation matrixes have important effects on plant growth. Therefore, it is very important to develop a substrate with strong fertilizer supply capacity, pH and EC suitable for the growth of green plants. In this experiment, with Quamoclit pennata as a green plant, five different cultivation matrix formulations using Fluvo-aquic soil, peat and vermiculite were made to study the changes of available nutrients in the growth of Q. pennata in different cultivation matrixes, and the growth conditions and seedling indexes of Q. pennata in different cultivation matrixes were analyzed. The results showed that the cultivation matrix of “Fluvo-aquic soil 50%+peat 30%+vermiculite 20%” and “Fluvo-aquic soil 40%+ peat 60%” had strong and stable ability to supply nitrogen, phosphorus and potassium. The pH and EC were also suitable for the growth of Q. pennata, and the seedling height, stem diameter, dry weight and strong seedling index were all higher. Thus, both of the above two substrates can be used as the cultivation matrixes of Q. pennata.
