    摘要:

    以青海省西宁市城北区大堡子乡日光温室土壤为研究对象,分析了种植年限分别为1年、3~4年、6年、 8年、15~18年、21年、30年日光温室土壤的盐分和养分含量情况。结果表明:随着日光温室种植年限的增加, 盐分含量较对照增加13.40 %~287.50%,pH值较对照下降10.13%~1.27%,两者呈相反趋势。随着日光温室 种植年限的增加,土壤中有机质、全氮、全磷含量明显高于对照,分别较对照增加11.31%~145.24%、44.60% ~172.47%、30.29%~191.70%;碱解氮含量较对照增加14.07%~122.28%;温室土壤中有效磷含量呈波动变 化,波动范围为21.88%~218.75%。

    Abstract:

    Sampling different planting years(1~30 years) soil in greenhouses from Dapuzi zone of Xining city,analyzing the content of soil salt and nutrients.The results showed that with the increasing of cultivation years,the salt content in- creased 13.40%~287.50%;pH reducing 10.13%~1.27% in contrast with the control,and they have opposite trends; The content of organic matter, total nitrogen and total phosphorus were significantly higher than the control,and the increas- ing percentage compared with the control area were 11.31%~145.24%,44.60%~172.47%,30.29%~191.70% re- spectively;meanwhile,the content of available nitrogen increased 14.07%~122.28% compared with the control area; The available phosphorus changed fluctuately, the percentage changing compared with control at 21.88%~218.75%.
