摘  要：
以发酵床垫料为主要原料的复合基质作为栽培基质,采用槽式栽培方式,研究连茬种植西瓜效果、种后基质理化和微生物学性状的变化特征以及棉隆消毒后旧基质连茬种植西瓜效果。结果表明:种完1茬西瓜的旧基质继续种植西瓜会出现再植障碍,整个生育期枯萎病发病率可达35%;种植西瓜对基质中尖孢镰刀菌数量影响显著,连续种植2茬西瓜后,基质中尖孢镰刀菌数量可从0升高至8.0×10~3cfu·g~(-1)基质;种完1茬西瓜的旧基质经棉隆消毒处理后,真菌和尖孢镰刀菌数量均显著减少,且继续种植西瓜后其产量和单果重与新配基质相比均无显著差异。

摘  要：
An experiment was conducted to study the effects of a soilless substrate composed mainly of deep-litter materials on watermelon cultivation and the effects of cultivation on physicochemical and microbiological properties of this substrate.The reuse effect of old substrate after disinfection was also studied.The results showed that replant obstacle would occur if old substrate was used to continue growing watermelon and the incidence of fusarium wilt could reach 35% during the whole growth period.The number of Fusarium oxysporum in the substrate increased from 0 to 8.0 ×10~3 cfu·g~(-1) after continuously two-crops growing of watermelon.The number of fungi and Fusarium oxysporum were significantly reduced in the substrate used once after dazomet disinfection.There was no significant differences in fruit weight and total yield when continue growing watermelon in disinfection substrate compared with in new substrate.
