- 摘要:
- 以大葱和苦瓜2种轮作作物为试材,分析了轮作不同蔬菜对连作黄瓜根际土壤微生态的影响。结果表明:轮作大葱和苦瓜可显著降低根际土壤EC值,提高pH。2种轮作作物根际土壤中的细菌和放线菌数量均有显著提高,真菌和镰刀菌数量显著降低。在拉秧期大葱和苦瓜根际土壤转化酶活性高于连作95.96%和44.44%,脲酶活性高于连作52.94%和29.41%,过氧化氢酶活性较连作高182.69%和100.00%,多酚氧化酶活性高151.11%和75.56%。黄瓜-大葱、黄瓜-苦瓜2种轮作模式有效缓解黄瓜连作障碍,防止土壤肥力衰退,以大葱轮作效果更为显著。
- Abstract:
- Welsh onion and momordica charantia rotation crop were used as materials,effects of different rotation crop on rhizosphere soil microecology of continuous cropping cucumber were analyzed.The results showed that the EC value of rhizosphere soil was decreased significantly while pH increased after welsh onion and momordica charantia rotation.The number of bacteria and actinomycetes in welsh onion and momordica charantia rhizosphere soil increased;the number of fungi and Fusarium oxysporum decreased.In the wane period,invertase activities in rhizosphere soil of welsh onion and momordica charantia were 95.96% and 44.44% higher than that of continuous cropping;ureases activities were 52.94% and 29.41% higher than that.Catalases were 182.69% and 100.00% higher than that of continuous cropping;polyphenol oxidases were 151.11% and 75.56% higher than that.Welsh onion and momordica charantia rotation crop were relief cucumber continuous cropping obstacle and prevented the soil fertility decline.The effect of welsh onion rotation was more significant.
