摘要
在三亚市抱坡岭受损山地的石质边坡,用F1尿素[CO(NH2)2,F2磷酸二氢钾(KH2PO4)两种化肥、C1(蛇藤+马棘+车桑子—地毯草+类芦+波斯菊+马尼拉结缕草)、C2(胡枝子+马桑+龙须藤—狗牙根+假俭草+结缕草+百喜草)两种草种组合及J1和J2两种建植方法进行人工植物群落建植的L4(23)试验,以当年秋季地上植物量为测度值进行综合评估,得4个试验处理,效果依次为:F2C1J2>F1C2J2>F1C1J1>F2C2J1。主要因子和次要因子分析表明:喷播建植技术>草种组合>肥料种类。对同一因子的不同水平进行效果比较发现:在肥料因子中,尿素F1比磷酸二氢钾F2好,在草种组合因子中,C1比C2效果好,在建植技术因子中,用客土喷播比湿式喷播好。
A L4 （2 3 ）orthogonal experiment design with 3 factors and 2 levels,including 2 fertilizers,2 mixed grasses and 2 construction methods,was used to construct artificial plant communities on the rock slope of the damaged Baopo Mountain in Sanya City.The aboveground biomasses in autumn were used as the evaluation in-dex.the effect order of 4 treatments was F2 C1 J 2 〉F1 C2 J 2 〉F1 C1 J 1 〉F2 C2 J 1 .The main factors and secondary fac-tors analysis indicated the order of importance was spraying and planting technology〉species combination〉fer-tilizers.The comparison of different levels of same factor indicated that urea was better than monopotassium phosphate for fertilizer factor;Celastrushookeri ＋ Indigoferapseudotinctoria ＋Dodonaeaviscosa-Axonopuscom-pressus ＋Neyraudiareynaudiana ＋Cosmos bipinnatu ＋Zoysia matrella was better than Leapedeza bicolor ＋Coriarianepalensis ＋ Bauhinia championi-Cynodondactylon ＋ Eremochloaophiuroides ＋ Zoysiasinica ＋ Pas-palumnatatu for grasses factor;soil spraying was better than wet spraying for planting technology factor.
