摘要
以八一镇设施大棚为对象,研究了不同种植年限设施菜地土壤养分变化以及对硝酸盐累积、不同种类蔬菜硝酸盐含量的影响。结果表明:随着大棚使用年限的增加,土壤基础养分均出现了累积,硝态氮累积较为明显,3年棚龄的大棚中叶菜类蔬菜已出现重度硝酸盐污染,茄果类蔬菜硝酸盐污染较低。
Taking local greenhouse in Bayi town as object,the main soil nutrient content and nitrate content in soil and vegetables were determinated based on local greenhouse in Bayi town.The results showed that the main soil nutrient content was abundant in greenhouse,nitrate content in soil was fast concentrated in 6years old,leafy vegetable were serious nitrate contamination in 3years old,gourd vegetable was nearly no contamination in greenhouse cultivation.
