为研究蔗地施用酒精发酵液对土壤物理学肥力特性的影响,2005～2007、2006～2007年分别在广西扶绥县昌平甘蔗试验基地两个点连续进行清水105.0 t/ha(CK)、习惯施肥+清水105.0 t/ha(CF)和酒精发酵液75.0 t/ha+清水30.0 t/ha处理试验。结果表明,在蔗地连续2～3年施用酒精发酵液,蔗地耕层土壤容重下降,总孔隙度和毛管孔隙度增加,土壤水稳性团聚体含量提高,土壤粘粒含量下降,蔗地土壤物理肥力特性得到改善,蔗地土壤未见板结。
In order to study the influence of alcohol fermentation broth on soil physical fertility in sugarcane field, 105.0 t / ha (CK) of fresh water was continuously washed at two points of Changping sugar cane experiment base in Fusui County, Guangxi from 2005 to 2007 and 2006 to 2007 respectively. Fertilization + water 105.0 t / ha (CF) and alcohol fermentation 75.0 t / ha + water 30.0 t / ha treatment test. The results showed that in the sugarcane field, alcoholic broth was applied continuously for 2 to 3 years. The soil bulk density decreased, the total porosity and capillary porosity increased, the content of water-stable aggregates increased, the clay content decreased, Soil physical fertility characteristics have been improved, sugarcane soil no plate knot.
