元谋干热河谷是我国典型的生态脆弱区,该区气候炎热干旱,植被退化严重,水土流失强烈,给造林工作增加了很大的困难。木豆根部具有根瘤,是干热河谷地区荒山、退耕还林地造林的优良树种。在对印度木豆多年适应性研究和木豆造林的实践经验基础上,总结了在该区域采用木豆进行造林的关键技术,即选择合适品种,采用鱼鳞坑或隔坡水平沟整地造林方式,施足底肥,直播造林,加强管理等。可为干热河谷区的造林提供参考。
Yuanmou Dry-hot Valley is a typical ecologically fragile area in our country. The climate in this area is hot and dry with severe degradation of vegetation and strong soil erosion, which adds great difficulties to afforestation. Roots of pigeon with nodules, dry and hot valley is barren hills, returning farmland to afforestation fine tree species. Based on the multi-year adaptability research of Indian pigeon pea and the practice experience of afforestation of Pigeonpea, the key technologies of reforestation using Pigeon pea in the region were summarized, that is, selecting appropriate varieties, Shi enough base fertilizer, live afforestation, and strengthen management. Can provide a reference for afforestation in the dry valley area.
