摘要
将污泥或家畜排泄物与植物秸秆堆肥化后形成的生物固体用作树木容器育苗基质 ,通过容器育苗试验 ,结果发现苗木具良好的生长响应。把育好的5万余株容器苗栽植于中德合作的陕西麟游造林科技推广示范区 ,1到2年后树木的成活率与保存率均明显优于裸根苗。
Biosolid is the product coming from the static aerotic composting process of sludge or live stock wa ste with corn stove under suitable conditions.It can be used as a substitute for peat.The proportion of the container media optimization∶biosolid∶loam soil=1∶2( V/V) and 2% (by weight) calcium superphosphate is added.The growth response of seedling in the container is better than the naked root seedling.After transplanted,the survived rate,the preserve rate and the growth rate is higher than that of naked root seedling.
