摘要
幼林橡胶园套种甘薯,不仅可提高复种指数,同时也可提高土壤墒情,改善林下气候环境,减少病虫害的发生和除草剂的使用,降低种植成本,有效增加单位土地面积的经济效益。本研究依据德宏州幼林胶园宽行密株特性和甘薯的生物学特征,分析橡胶套种甘薯特色产业发展优势,系统介绍橡胶林下套种甘薯的栽培管理技术,旨在为调整当地农业产业结构和橡胶产业的可持续发展提供参考。
Intercropping sweet potatoes in young rubber plantations can not only improve the multiple cropping index,but also increase the soil moisture,improve the climatic environment under the rubber trees and reduce the occurrence of plant diseases and insect pests and the use of herbicides.Thus,it reduces the planting costs,and effectively increases the economic benefits per unit land area.Based on the characteristics of wide-row and dense plant in young rubber plantations in Dehong Dai and Jingpo Autonomous Prefecture and the biological property of sweet potatoes,this paper analyzed the development advantages of intercropping sweet potatoes in the rubber plantations,and systematically introduced the cultivation and management techniques of intercropping sweet potatoes under the rubber trees,so as to provide a reference for adjusting the local agricultural industrial structure and the sustainable development of the rubber industry.
