摘要:
为解(jie)决工程(cheng)(cheng)技术中的(de)人(ren)工基(ji)质(zhi)(zhi)粘(zhan)结性、通透(tou)性及(ji)有机(ji)养分问题,对添(tian)加(jia)水(shui)泥(ni)、木屑、稻(dao)草及(ji)泥(ni)炭土(tu)(tu)等的(de)理(li)化(hua)性质(zhi)(zhi)进行系统测定。结果显示: 水(shui)泥(ni)加(jia)入(ru)土(tu)(tu)壤后,不(bu)仅(jin)导致(zhi)pH值的(de)显著上(shang)升,还引起土(tu)(tu)壤的(de)硬(ying)化(hua)及(ji)最大持(chi)水(shui)量的(de)显著降低(di)(P0.05)。使用酸(suan)度矫正液(ye)Ⅲ进行基(ji)质(zhi)(zhi)改良,水(shui)泥(ni)添(tian)加(jia)量完全可以(yi)(yi)超过(guo)基(ji)质(zhi)(zhi)质(zhi)(zhi)量的(de)2.0%。木屑和(he)泥(ni)炭土(tu)(tu)的(de)添(tian)加(jia),显著提高了土(tu)(tu)壤持(chi)水(shui)能(neng)力(li),并(bing)从一(yi)定程(cheng)(cheng)度上(shang)缓解(jie)了粘(zhan)结剂引起的(de)土(tu)(tu)壤硬(ying)化(hua)(P0.05)。由(you)于2 mm直径的(de)稻(dao)草会造成土(tu)(tu)壤过(guo)度松散,可能(neng)降低(di)基(ji)质(zhi)(zhi)的(de)抗(kang)侵蚀能(neng)力(li),所(suo)以(yi)(yi)不(bu)宜应(ying)用。通过(guo)试验(yan),确定了进一(yi)步(bu)深入(ru)试验(yan)的(de)各添(tian)加(jia)成分的(de)上(shang)限(xian)含量。
