摘要
根据鹤庆金沙江流域的气候、土壤和社会经济等条件,选用苏门答腊金合欢、新银合欢、黑荆作为主要的造林树种。采用不同的处理方法分别在昆明的实验室和造林区进行发芽试验,结果表明:用始温90℃浸种24h后播种,出苗效果好,苗圃出苗率分别为49 69%、65 74%、58 64%,室内试验发芽率分别为66 5%、83 0%、87 0%。在苗木定植后半年和一年内分别进行调查,分析造林效果,认为所选树种适合在鹤庆金沙江干热河谷地区种植,值得推广。
Based on the conditions of climate, soil, socio-economy of Ginsha River of Heqing county, three species namely Acacia glauca, Leucaena leucojphala, Acacia mearnsii, are mainly selected for afforestation. Different processes have been adopted for germination test in the lab in Kunming and forestation area respectively. It results that the process under the condition of soaking in 90 ℃ of hot water for 24 hours displays satisfactory germination percentage. Moreover, since investigations were differently done after half year and 1-year planting, it concluded that all selective reproducing tree species deserved to be iterated and disseminated in this valley area.
