摘要
对八种海南热带花卉复合种植模式的生态效益和经济效益进行了探索性试验。结果表明:热带花卉复合种植,能有效降低林内温度、增加林内湿度,对生态环境有显著改善;从经济收益方面考虑,火焰木+散尾葵、盆架子+鹤蕉、鸡蛋花+黄金榕模式的苗木的平均年生长量与纯林对照相比不仅没有减少,反而有所增加。因此,选用合适的品种进行复合种植,能有效提高土地利用率,在获得同等经济收益的情况下,还可改善生态环境。
An exploratory test was carried out to study the ecological and economic benefits on eight intercropping patterns of tropical flowers.The results show that: the intercropping of tropical flowers can improve the ecological environment by reduce temperature and increase humidity;from the economic benefits to consider,Spathodea campanulata + Chrysalidocarpus lutescens,Alstonia scholaris + Heliconia and Plumeria rubra + Ficus microcarpa pattern have better economic benefits as the annual growth of green tree increased compared to pure forest.Therefore,suitable intercropping pattern can effectively raise the utilization rate of land and improve the ecological environment at equal economic gains.
