采用固体发酵与微生物浸出相结合利用白云鄂博富钾板岩的方法

The Method For Solid-state Fermentation Combined with Bioleaching in the Utilization of K-rich Slate

为了解决白云鄂博地区富钾板岩资源生态化利用的问题,采用固体发酵与微生物浸出相结合的方法对富钾板岩的利用进行了研究.研究发现,可以同时制备出固体和液体两种肥料.肥效验证结果表明,液体与固体肥料均能显著提高番茄种子的发芽率及发芽势,MDA施肥在西红柿生长期间的各个时间段都显著低于MDA不施肥,说明所生产肥料可显著提高番茄的生长效率并可增加其抗损伤能力,证明用微生物分解白云鄂博地区富钾板岩制备复合肥料是生态、环保、可行的方案.

For eco-utilization of K-rich slate in Bayan obo,we employed solid-state fermentation combined with bioleaching in the utilization of K-rich slate.The results shown that solid and liquid fertilizer can be prepared at the same time.The verification of fertilizer efficiencies shown that these two fertilizers both can improve the germination rate and germination potential of tomato seeds,and MDA being higher when fertilization.It is illustrated that the two fertilizers can improved the growth efficiencies of tomats and abilities to resist damage.So it is an ecological,environmental friendly and feasible scheme.
