摘　　要：在盆栽条件下,蓖麻秆、菜籽饼分别与脂肪酸按一定比例与土壤混合,评价不同组合对辣椒生长和根结线虫的调控作用。结果表明:添加蓖麻秆处理的辣椒生长受到抑制,植株矮小,叶子脱落,生物量下降;但添加脂肪酸后,蓖麻秆对辣椒的植物毒害效应得到缓解,生长明显改善;添加菜籽饼能够显著刺激辣椒生长。另外,蓖麻秆、菜籽饼与脂肪酸组合的各处理均能显著降低根结线虫的种群密度。An experiment was performed to evaluate the soil organic amendments（castor straw ,rapeseed cake alone or in combination with fatty acids） effects on pepper growth and the population density of root kont nematodes. The results showed that the addition of castor straw inhibited pepper growth with lower plant hight,leaf number, and root biomass and shoot biomass as compared to control. However, the inhibited growth was ameliorated via the addition of fatty acids. In contrast, the addition of rapeseed cake enhanced the pepper growth. In general, the treatments with soil organic amendments had lower number of eggs of root knot nematodes as compared to the controls, indicating that these approaches could be used for controlling root knot nematodes.
