为增加玉米生长积温，提高保苗率，以充分利用农业废弃物。根据各地育苗基质来源不同，以牛粪、草炭和稻壳友为主要原料，按照一定比例与土壤配比，进行不同配比基质筛选。结果表明：处理2以牛粪20％、草炭30％、稻壳灰20％和土壤30％作为育苗基质，对玉米幼苗素质影响最好，其幼苗叶绿素含量和根系生长量等各项指标均好于其它基质处理，处理1和处理3之间育苗效果差别不明显，但不如对照处理。说明以农业废弃物作为育苗基质，可部分或全部代替土壤育苗，还可对农业废弃物进行循环利用。

In order to increase accumulated temperature during maize growth and enhance the emerging rate, because of different resource of agriculture by-products for breeding medium,the main materials such as shard, turf and rice husk ash were selected according to certain portion with soil. The results showed that the treatment 2,when the shard 20% ,turf 30% ,rice husk ash 20% and soil 30% had the best impact on the seedling quality,its chlorophyll and roots growth were both better than CK , the treatment 1 and treatment 3 were not different,and both worse than CK. Let by-products as seedling breeding mediums partly or completely to replace soil breeding seedlings would have good guidance significance for agricultural waste recycling.
