摘要
试验检测滇西红层区公路弃渣场典型红层土营养特征指标,概述其影响植物生长的主要制约因素。基于普遍的公路弃渣场复垦造耕需求,结合滇西红层区内适中农作物营养成分要求,提出弃渣场红层土壤改良方法并进行试验验证效果。
The nutrient characteristics of typical red bed soil in highway waste dump in red beds area of Western Yunnan are inspected by tests,and the main factors affecting plant growth are summarized.Based on the general needs of reclamation and cultivation of highway waste dump,combined with the requirements of moderate crop nutrients in the red layer area of Western Yunnan,the improved method of red layer soil in waste dump is put forward and verified by experiment.
