将莴苣和芹菜2种作物分别与番茄套作,研究了套作对番茄生长、产量、品质及根系土壤微生物数量和酶活性的影响,以期明确不同套作模式对番茄连作障碍的影响。结果表明:套作处理可以显著增加连作土壤中微生物总量、细菌数量和细菌/真菌比例,显著降低真菌数量,同时提高土壤中蔗糖酶、脲酶、磷酸酶和过氧化氢酶活性,从而减轻连作对番茄生长的影响,提高番茄产量,缓解番茄连作障碍。
The effects of intercropping on tomato growth, yield, quality, soil microbial population and enzyme activity were studied with two crops of lettuce and celery, respectively. The effects of different intercropping modes on the continuous cropping obstacle of tomato were studied. The results showed that the intercropping treatment could significantly increase the total amount of microorganisms, the number of bacteria and the ratio of bacteria to fungi in the continuous cropping soil, significantly reduce the number of fungi and increase the activities of sucrase, urease, phosphatase and catalase in the soil, Impact on tomato growth, increase tomato yield, ease tomato continuous cropping obstacles.
