山地果园生态栽培的环境效应

以福建漳州山地果园为例,进行果园套种、间种牧草生态栽培试验,结果表明:果园套种和间种等生态栽培模式与清耕果园相对照,果园温度日变幅缩小,明显地改善了果园温度状况,增强了果园抗高温的能力。同时,果园泥沙流失量分别减少了26 3%和48 4%,土壤有机质含量分别增加了49 5%和34 2%。这说明,果园生态栽培对于调节果园环境温度、保持水土和提高土壤肥力等具有良好的生态环境效应,为果园生态环境的治理与改善、山地资源的保护与开发起到了很好的示范作用。图1,表3,参4。

Environment effects of ecology planting of orchard in mountainous region

The paper takes example for Zhangzhou city of Fujian province, an orchard ecology planting test was be carried in mountainous region, the result showed: the orchard which performing inter-planting and cover-planting compared to the bare-planting orchard, the temperature changed in daily was declined, the ability against high temperature was enhanced, the lost of water and soil decreased 26.3% and 48.4% respectively, and the organic capacity of soil was increased 49.5% and 34.2% respectively, which indicated the method of orchard ecology planting had better environment effects in aspect of adjusting temperature, water and soil conservation and improving soil fertility. It has important function of lead the way to protect ecology environment of orchard and exploit the mountainous resources.
