摘　　要：核桃林下种植是利用核桃林下空地和空间种植适宜的低矮经济植物。文章综述了核桃林下种植对土壤容重、孔隙度、水分及土壤pH值、有机质、养分和微生物等土壤性质的影响,发展核桃林下经济植物种植可以有效改善土壤物理、化学和生物学性质,有利于提高土地利用效率和增加经济收入,对促进核桃产业可持续发展具有积极作用。Under-forest planting in walnut grove is a method of cultivation and management which is plant a suitable low economic plants in the gap between forests.The effects of planting under walnut plantation on soil properties such as bulk density,porosity,water content,soil pH,organic matter,nutrients and microorganisms were summarized in this paper.The results showed that the development of economic plant planting under walnut forest could effectively improve soil physical,chemical and biological properties,improve land use efficiency and increase economic income,and play a positive role in promoting the sustainable development of walnut industry.
