整地措施及苗木类型对麻疯树生长的影响研究

麻疯树耐旱、耐瘠薄,广泛分布于海拔1 500 m以下的干热河谷地区,不仅是干热河谷地区的水土保持树种,也是开发利用前景较好的能源植物。受立地条件及栽培管理措施的影响,双柏县麻疯树座果率低、单株产量小,产量极不稳定。2006～2011年在双柏县大沙坝进行不同整地措施和苗木类型造林试验,结果表明,科学整地、科学选择苗木及合理密植可促进麻疯树速生、丰产和稳产。

Effects of Soil Preparation Measures and Seedling Type on the Growth of Jatropha curcas

Jatropha c,trcas is widely distributed in dry and hot valley below an altitude of 1 500 m, with the characteristics of drought tolerance, Not only it is the species for dry and hot valley soil and water conservation, but also is the energy plants. Influenced by site conditions and cultivation management measures, fruit setting and per plant yielding of Jatropha curcas are low and unstable. The trial of differ- ent soil preparation measures and seedlings Afforestation were conducted from 2006 to 2011 in Shuangbai County Dashaba, results showed that the scientific soil preparation, the scientific seedlings selection and rational close planting can promote fast-growing, high yield and stable production of Jatropha curcas.
