| 摘 要： | 对利用工业固体废弃物脱硫灰与富钾硅酸盐矿物复合生产的新型硅钙钾土壤调理剂进行了木薯种植试验,并与不施肥、配方肥+有机肥进行了对比。结果表明,与不施肥相比,施用配方肥+有机肥、配方肥+脱硫灰硅钙钾土壤调理剂后,木薯的叶绿素含量均增加。茎基部粗度以不施肥最小,配方肥+有机肥和配方肥+脱硫灰硅钙钾土壤调理剂略高。施用配方肥+脱硫灰硅钙钾土壤调理剂、配方肥+有机肥能较明显提高单株结薯数与木薯产量,分别较不施肥处理增产80.7%和64.1%。在经济效益方面,施用配方肥+脱硫灰硅钙钾土壤调理剂经济效益最高,较不施肥提高79.5～409.3元/hm2,其中乐昌试验区施用效果最好。

| Abstract: | In this paper,cassava planting experiment had been done with new silicon calcium potassium soil amendment, which was compound produced by industry solid reject desulphurization ash and rich potassium silicate mineral, and had been compared with two other conditions: without applying fertilizer and multi-fomula fertilizer add organic fertilizer. The results indicated that compared with conditions of without applying fertilizer, after applying multi-fomula fertilizer add organic fertilizer, multi-fomula ferti... |
