| 摘 要： | 对宁河不同地区不同年限设施栽培土壤盐分特性进行了多点取样及综合调查分析。结果表明,设施土壤全盐含量有表聚现象,且均高于大田;1～2年设施土壤含盐量高,与其他处理之间显著差异,是新建棚室障碍的关键因素之一。全盐与EC值在0～20cm土层呈线性正相关,R2=0.9296。土壤硝酸盐随着种植年限延长逐渐累积。随着种植年限增加,土壤pH值呈降低趋势,随着土壤深度增加,pH值逐渐升高。

| Abstract: | Salt characteristics of different aged greenhouse soil from Ninghe county in Tianjin city were investigated. The results showed that salt accumulation in the greenhouse soil profiles was chiefly in 0~20 cm layers. The content of total salt and EC value in greenhouse soil was significantly higher than in the open field. The content of total salts and the EC value also showed linear correlation in 0~20 cm soil layer,R2=0.929 6.The content of total salt of 1~2 years greenhouse soil treatments were significantly difference from the others. Salt is obstacles of the new Greenhouse. The pH value decreased slightly with extended of planting age. With the soil layers deep,greenhouse soil pH value gradually increased in 0～60 cm soil. |
