中轻度侵蚀区杨梅林套种植物阻控水土流失效益研究

Study on Planting Benefits of Plants Controlling Soil and Water Loss under the Forest of Myrica rubra in Moderate and Mild Soil Erosion Area

长汀杨梅生态园属于中轻度水土流失区,该试验在杨梅林下套种黄栀子、宽叶雀稗、百喜草、杭白菊4种植物,对比不同植物带来的不同的生态效益、景观效益和经济效益。结果表明,4种植物均能起到阻控水土流失、提高杨梅林产量的作用。其中,生态效益较好的是黄栀子和宽叶雀稗;景观效益较优的是黄栀子和杭白菊;经济效益较高的是黄栀子和百喜草。综合比较可知,黄栀子的综合效益较突出,可选择其作为生态园水土保持集成与示范重点植物。

The Changting ecological Myrica rubra park belongs to the mild soil erosion area, planting Gardeniajasminoides, Paspalum wettsteinii, Paspalum notatum, Chrysanthemum morifolium, four kinds of plants under Myrica rubra. Compare different ecological benefits and different landscape benefits and economic benefits. The results show that four kinds of plants can play a role in controlling soil erosion, improving the yield of Myrica rubra. The ecological benefits of Gardeniajasminoides and Paspalum wettsteinii are better than others;The landscape benefits of Gardeniajasminoides and Chrysanthemummorifolium are better; The economic benefits of Gardenia jasminoides and Paspalum notatum are higher. Comparing the comprehensive benefits, Gardenia jasminoides can be chosen as the key plant for controlling soil and water loss.
