| 摘 要： | 研究了武山县大棚蔬菜不同连作年限对韭菜产量、品质和土壤养分状况的影响.结果表明:随着韭菜连作年限的增加,产量和品质下降,且下降幅度随连作年限的增加而增大,土壤中全氮、速效磷和有机质的含量增加;速效钾含量减少;土壤pH值降低;随着连作年限的增加,土壤表层出现盐类累积.说明土壤养分失衡和盐渍化有可能是造成韭菜产量和品质下降的重要原因. |

| Abstract: | Effects of continuous cropping on the yield of Chinese chives and soil nutrition were studied in plastic shed cover.the results showed that the yield and quality of Chinese chives decreased along with the continous cropping.The content of N,P and organic matter accumulated obviously,however,the content of K and pH reduced.The chemical property of surface soil became worse and the salt accumulated.It was suggested that the decrease of output and quality was caused by soil nutrient unbalanced and soil salt accumulation. |
| Keywords: | plastic shed Chinese chives continuous cropping yield quality soil nutrient |
