| 以配置合格水稻育苗基质为目标，针对现有水稻育苗基质的生产原材料多以草炭为主对环境影响大的问题，探索利用煤矸石作为水稻育苗基质的可行性研究，在生产育苗基质的同时做到固体废弃物的资源化利用。通过对试验原料进行前处理和各项理化性质的测定及试验前进行的配比试验，确定了适合水稻育苗基质的4个处理作为试验组与对照组进行了水稻育苗试验。结果表明：（1）煤矸石可作为水稻育苗基质的材料；（2）煤矸石的最大添加量可达到80%（体积比），但需要进行活化处理；（3）不经活化处理的煤矸石也可用于水稻育苗，生长情况也较好，但煤矸石的添加量缩减至38%（体积比）。 |
| 英文摘要: |
| Peats are the mostly used material in making rice seedling substrate. However, mining peats could cause environmental problems. In order to reduce or replace peats in rice seedling substrate industry, this paper studied suitable way to configure rice seedling. The coal gangue was used to experiment cultivating rice. Four rice seeding experiments were carried out based on physical and chemical properties of materials attributes. The results showed:(1) Coal gangue was feasible for rice seedling; (2) The maximum adding amount of coal gangue was 80%(volume ratio) though the coal gangue need to be activated; (3) In the case of no activated treatment only 38%(volume ratio) of coal gangue could be added to the substrate. |
