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.

To study the effects of vinasse application on physico-chemical properties of soil, different treatments viz.,(i) spraying water @ 105.0 t/ha (CK), (ii) conventional fertilization + spraying water @ 105.0 t/ha (CF) and (iii) soil application of vinasse @ 75.0 t/ha + spraying water @ 30.0 t/ha, have been applied in two sugarcane fields in Fusui County,Guangxi, during 2005-2007 and 2006-2007, respectively. The results showed that, after 2-3 years of continuous vinasse application to sugarcane fields, the soil bulk density declined, while the total porosity and capillary porosity increased in the plow layer of soil. The soil water stable aggregate content enhanced, but the soil clay content decreased. The vinasse application in sugarcane field resulted in improved physical properties of soil and soil hardening was not detected in the field.
