Abstract:
Taking watermelon of ‘Xiaofu’ as test material，watermelon of ‘Xiaofu’ was continuously grown in five croppings on the plot with the same cultivating management to seek the variation appearances of pH，nutrient contents，microorganisms，enzymes activity in the soil，and to explore the quality character of watermelon fruit.The results showed that soil pH gradually decreased with increasing cropping frequency；and the changes of soil organic matter，N，P and K contents were not obvious；the quantities of bacteria and actinomycetes in the soil increased before the third cropping and decreased at the sequent cropping，but an opposite trend was found on fungi；the activities of proteinase，catalase and urease in the soil were in a state of decline during the experimental period；positive correlation was found among the quantities of actinomycetes and the activities of proteinase，catalase，alkali solution N in the soil；vitamin C content of watermelon fruit decreased under continuous corpping condition.
