摘　　要：[目的]测定分析米糠灰主要营养成分及其对油茶嫁接苗成活和生长的影响,寻求和开发低成本、高养分的生物有机肥原料。[方法]在测定米糠灰所含主要营养成分的基础上,调查施用米糠灰对2个油茶优良无性系嫁接成活和幼林生长的影响。[结果]米糠灰中有机质、淀粉、蛋白质和脂肪含量分别为349.0、295.2、65.8和5.0 g/kg;长林4号和40号油茶优良无性系育苗基质添加米糠灰后,嫁接成活率分别达到92.5%和91.0%,显著高于未施肥水平;施入米糠灰后油茶幼林株高、地径和冠幅均显著高于对照,不同坡位条件下油茶幼林施肥生长效应不同。[结论]米糠灰可作为优质的有机肥在油茶育苗和幼林培育中应用。[Objective] To determine the nutrition composition of rice husk ash and its effect of differential grafting on the survival and growth,in order to seek and develop low cost and high nutrient biological organic fertilizers. [Method]The contents of main nutritional components of rice bran ash were analyzed. Its effect on the grafting survival rate and the growth of two superior clones of Camellia oleifera grafting seedlings were surveyed in this study. [Result]The results showed that the content of organic matter,starch,protein and fat in rice bran ash were349. 0,295. 2,65. 8 and 5. 0 g / kg,respectively. After adding rice bran ash in light media,the graft survival rates of Chang Lin No. 4 and No. 40 were 92. 5% and 91. 0%,respectively,significantly higher than that of control. The height,ground diameter,crown diameter of the young trees were significantly higher than control,but the fertilization effect of different slope positions were different. [Conclusion]Rice bran ash can be used as efficient biological organic fertilizer to application in seedling and culture.
