摘要
以峨眉假俭草为材料,种植在石骨质土、紫色土、垃圾、河滩土、粗砂5种不同的基质上。采用随机区组设计,研究不同基质对峨眉假俭草营养元素及植物量的影响,结果表明:当假俭草植株体内K含量小于5.55g/kg时,植株叶片表现出缺K现象,应在7,8月对假俭草追施一定量的K肥。以石骨质土处理的峨嵋假俭草地上、地下植物量最小。
Emei centipedegrass was sowed in following five various soil substrate: stony soil, purple soil, beach soil, rubbish , coarse sand. The result showed that the potash fertilizer was needed while the potash content in plant tissue was less than 5.55g/kg. Biomass of Emei centipedegrass planted in stony soil is the smallest.
