本发明公开了种富硅生物炭有机肥，利用了稻谷壳高的Si含量，采用三次发酵工艺得到丰富的水稻可利用的有效硅，并结合稻谷壳生物炭较高的pH值和硅含量、较大的比表面积的特点，通过发酵的稻谷壳与稻谷壳生物炭两种材料的结合，形成多方面的互补，发酵后稻谷壳中的硅肥速效性较好，有利于作物在短期内利用，而稻谷壳生物炭中的硅，能在微生物作用下较缓慢地释放，能满足作物较长时间内对硅的需求。 The invention discloses a silicon-rich biochar organic fertilizer. Based on high Si content of rice husk, rich effective silicon available for rice is obtained by use of a triple fermentation process; besides, in combination with the relatively high pH value and silicon content and relatively large specific surface area of the rice husk biochar, the two materials, namely the fermented rice husk and the rice husk biochar, are combined to form complementation in a plurality of aspects; the silicon fertilizer in the fermented rice dusk is excellent in fast-acting property and advantageous for crops to utilize in short time; besides, the silicon in the rice husk biochar is slowly released under the microbial action so as to meet the demands of crops on silicon within long time.
