摘要
以黑木耳生产过程中产生的废弃菌糠为原料,添加自制的发酵菌剂,在对发酵过程进行合理优化的基础上,生产菌糠有机肥并对其肥效进行研究。结果表明,菌糠在发酵过程中,达到55℃以上发酵温度的天数为14 d、C/N为24、T值为0.37、GI值为87.2%,达到完全腐熟的标准。制备的菌糠有机肥可以显著提高小白菜的根长、根系活力,与等量的化学无机肥处理相比,产量提高了24.37%。同时还可以维持土壤处于较高的肥力水平,与种植前土壤相比,显著提高了碱解氮、速效磷和有机质的含量。因此,采用此方法生产黑木耳菌糠有机肥可以实现资源的有效再利用,值得今后在当地进一步推广。
The waste fungus chaff emerged in the process of black fungus production was used as material for manufacturing organic manure. Self-made fermentation agent was added and the fermentation process was optimized.And its fertilizer efficiency was studied. The results showed that the time of fermentation temperature being morethan 55℃ was 14 days. C/N, T, GI was 24, 0.37, 87.2%, respectively, which reached the standard of complete compost. The new manufacturing organic fertilizer from black fungus chaff improved the root length and activity of Chinese cabbage. Its output was increased by 24.37% compared with the same amount of chemical inorganic fertilizertreatment. Meanwhile the soil was maintained at a high fertility level. Compared with the soil before planting, thecontent of alkali-hydrolyzable nitrogen, available phosphorus and organic matter had been greatly improved. Usingblack fungus chaff to manufacture organic manure in this method can realize the effective reuse of resources, whichis worth further widespread in the future.
