| 摘 要： | 本研究以膨润土和食用菌栽培的废弃物木耳菌糠为原料,将二者进行不同比例混合制得膨润土/废菌糠复合剂.研究结果表明:菌糠中添加膨润土能够降低菌糠交换性酸含量,菌糠的pH值<5.5,加入膨润土后pH值提高至6.5以上,有利于作物生长;保水性能和复合荆混合比有关,即复合剂(膨润土:木耳菌糠,质量比,下同)1:2>1:4>1:6>1:8>原木耳菌糠>黑土,膨润土的加入增强了菌糠保水性能;对NH_4~+吸附性能力也与复合荆的混合比有关,即1:2>1:4>1:6>1:8>黑土>木耳菌糠,膨润土的加入有效降低了木耳菌糠NH_4~+的流失.

| Abstract: | In this experiment, using the bentonite and waste aricularia-bran as raw materials, the composite was prepared in different mixing ratio of betonite to waste auricularia-bran. The results show that: mixing the betonies into the waste auricularia-bran can reduce the content of exchangeable acid , the original pH value of auricularia-bran is less than 5.5, after mixing bentonite, the pH value raises to higher than 6.5, which is advantage to the growth of crops; The capability of moisture conservation is relat... |
