以提取皂苷后的黄姜药渣作为主要原材料,通过添加有益微生物、腐植酸钾、沸石粉等辅料,研究发酵制得生物有机肥料的原料及配比。结果表明,黄姜药渣50%、沸石粉21%、豆饼17.5%、过磷酸钙10%、腐植酸钾1%、红糖0.5%,添加少量巨大芽孢杆菌、胶质芽孢杆菌、圆褐固氮菌、EM菌,在30~42℃环境下发酵20天,获得发酵成品,经检测符合生物有机肥料标准。通过此法制得的生物有机肥,生产成本低,同时减少了药渣对环境造成的污染,使药渣变废为宝。
The extract of saponin after the ginger ginger dregs as the main raw material, by adding beneficial microorganisms, potassium humate, zeolite powder and other materials to study the fermentation of bio-organic fertilizer raw materials and ratio. The results showed that 50% of yellow ginger dregs, 21% of zeolite powder, 17.5% of soybean cake, 10% of superphosphate, 1% of potassium humate and 0.5% of brown sugar added a small amount of Bacillus megaterium, EM bacteria, fermentation at 30 ~ 42 ℃ environment for 20 days to obtain the finished fermentation products, tested in line with bio-organic fertilizer standards. The bio-organic fertilizer obtained through the method has the advantages of low production cost, reduced pollution caused by dregs on the environment and transformation of the dregs into treasure.
