| 摘 要： | 采取调查取样的方法对河北永年县小龙马乡蔬菜种植区蔬菜连作和菜粮轮作2种管理模式的温室土壤的盐分和硝态氮进行了比较分析，结果表明：与蔬菜连作相比，蔬菜、玉米轮作可使0～20cm耕层全盐量、电导率比连作降低43%，36％；0-60cm土壤硝态氮比连作降低32％。说明蔬菜和玉米轮作可大大降低温室土壤盐分和硝态氮积累，对于延长保护地使用期限具有重要意义。

| Abstract: | The contents of salt and nitric nitrogen in greenhouse soils with vegetable continuous cropping or vegetable-maize rotation were studied in the vegetable cultivation areas of Xiao-longma in YongNian county of Hebei province. The results showed that,compared with continuous cropping,the total salt and electric conductivity in the 0-20era soil profile of vegetable-maize rotation field decreased by 43% and 36%, respectively and the nitric nitrogen in the 0-60cm soil profile decreased by 32%. |
