| 摘 要： | 分析了西瓜不同连作年限砂田土壤微生物、物理化学性状以及西瓜的产量和品质.结果表明,砂田土壤微生物量碳、氮均在连作5～10 a后有较大幅度下降;有机质和速效养分含量均不同程度降低,土壤肥力在下降.微生物量碳、氮与土壤养分之间存在一定关联,但未达到极显著水平,尚不能作为判断土壤肥力变化的标准.砂田西瓜的产量和品质随土壤肥力... |

| Abstract: | In order to evaluate the changes of sandy soil fertilizer and quality of watermelon soils in Gansu regions,the sands microbial,physical and chemical characteristics and yield and quality of watermelon were investigated in different replanting.The results showed that soil microbial biomass carbon and nitrogen has a large decreasing after replanting 5 to 10 years;the dropping of organic and available fertilizer contents indicated the soil was parched.Because the relationship between microflora,physical and ch... |
