1. Introduction
Fusarium wilt of cucumber is caused by the soil-borne pathogen Fusarium oxysporum f. sp. Cucumberinum (Cao et al., 2011). This disease was initially recorded in Crete, Greece, in 1989 and is now observed in many countries (Pavlou and Vakalounakis, 2005). Currently, Fusarium wilt is one of the most destructive diseases of greenhouse-grown crops and causes significant yield losses (Chen et al., 2010; Zhao et al., 2012). In China, this disease was initially reported in 2000 (Vakalounakis et al., 2004). Recently, many areas in China have been suffering from significant Fusarium wilt in crop outbreaks due to the increasing reliance of greenhouse crop cultures (Li et al., 2012). Until now, the most common method to control Fusarium wilt has been soil disinfection with chemical disinfectants (Mao et al., 2012; Meszk and Malusà, 2014; Shi et al., 2009). However, the use of these disinfectants has generated considerable recent concern regarding food safety and environment pollution because of their high toxicity (Mao et al., 2012), although some new soil fumigants are said to be minimally toxic (Qiao et al., 2012; Wang et al., 2013). With the development of biological technology, many researchershave focused on ecologically controlling this disease using antagonistic microorganisms (Chen et al., 2011; Li et al., 2012; Shen et al., 2015a,b; Zhao et al., 2012). Successful suppression of soil pathogens and reduce of Fusarium wilt had been reported in some cases (Qiu et al., 2012; Zhang et al., 2008). However, the widespread application of these antagonistic microorganisms in the field remains challenging because these biocontrol agents cannot change the deteriorated soil environment, and the microorganisms often cannot colonize the soil (Alabouvette et al., 2009; Wei et al., 2011). Acidification and salinization of greenhouse soil are serious issues that favor the proliferation of soil pathogens (Triky-Dotan et al., 2005; Yao et al., 2015). The soil pH in most of southern China is less than 6.0 due to excessive chemical fertilizer application. Determining an alternative effective and ecological method to control Fusarium wilt is necessary. Soil solarization is a non-chemical method of soil disinfection that results in pathogen control and nematode, insect, and weed management (Bonanomi et al., 2008;). Solarization is currently used all over the world. However, soil solarization is a climatedependent process, typically lasting more than 4 weeks (Gilardi et al., 2014). This long duration decreases compatibility with intensive agricultural systems. For soil solarization to become a more widely adopted method, it is always combined with other methods, such as organic amendments and flooding (Ashworth et al., 2013; Gilardi et al., 2014; Klein et al., 2012). Soil solarization combined with organic amendments (SS-OA) shows great potential for controlling soil-borne pathogens and is considered one of the most effective methods because it is ecologically friendly and is associated with low costs (Gilardi et al., 2014). Soil solarization combined with flooding (SS-F) is commonly used in greenhouses in south China to control Fusarium wilt. SS-F is easily performed and efficiently reduces the incidence of Fusarium wilt in cucumber for that growing season. However, this disease can easily occur in the subsequent year, a process that, until recently, few reports have explained (Matheron and Porchas, 2010; Mauromicale et al., 2010). Finally, the combination of soil solarization with organic amendments and flooding (SS-OA-F) has been implemented in recent years in some area, but the differences in the suppression of Fusarium wilt among SS, SS-F, and SS-OA-F treatments have not been well demonstrated. Their impacts on soil microbial community were rarely investigated. Therefore, the durative effects of Fusarium wilt suppression using these techniques are unclear. In this study, the efficiency of these three types of solarizationbased ecological soil treatments for the control of Fusarium wilt, remediation of a deteriorated soil environment, and their impacts on the soil microbial community were investigated and compared in pot experiments. Soil pH, conductivity, and the number of pathogenic Fusarium oxysporum were measured during the process. Changes in the soil microbial community were analyzed using 454 high-throughput sequencing. The suppression durations of different methods on the control of cucumber Fusarium wilt were evaluated by twice-continuous cropping.
