摘要: 为探明冀东典型地区设施土壤性质及养分特征,对唐山市和承德市的设施大棚进行了调查,采集表层土壤样品并对其进行了检测。结果表明,表层土壤pH平均值为6.20~7.49,以中性或碱性土壤为主,酸性土壤所占比例为26.32%。全盐含量平均值为2.55~9.30 g/kg,74.74%的土壤为盐渍土。滦南县和乐亭县同时存在较高比例的酸性土壤及盐渍土。从有机质(平均值为1.93%~2.57%)来看,土壤以中等以上肥力水平为主;从有效磷(平均值为69.97~1 018.3 mg/kg)、速效钾(平均值为232.31~713.32 mg/kg)、全氮(平均值为0.13%~0.39%)和全磷(平均值为0.09%~0.15%)来看,土壤以高肥力或极高肥力水平为主。土壤全钾平均值为0.15%~0.17%,均为极低肥力水平。研究结果揭示了冀东典型地区设施大棚表层土壤的酸化、盐渍化趋势与不均衡的高养分积累特性,为土壤养分管理提供了理论依据。

Abstract: Surface soil samples of greenhouse in Tangshan city and Chengde city were collected and detected to investigate the characteristics and nutrition profiles of greenhouse soils in typical areas of east Hebei. The results showed that the average value of pH was 6.20~7.49, and the dominant soils were neutral or alkaline, and the ratio of acid soil was 26.32%. The average value of total salt content was 2.55~9.30 g/kg, and the ratio of salt-affected soil reached 74.74%. High ratios of acid soil or salt-affected soil were found both in Luannan county and Leting county. According to organic matter concentrations(average values of 1.93%~2.57%), the dominant soils were at middle or high fertility levels. According to available phosphorous(average value of 69.97~1 018.3 mg/kg), available potassium (average value of 232.31~713.32 mg/kg), total nitrogen (average value of 0.13%~0.39%), and total phosphorus (average value of 0.09%~0.15%), the dominant soils were at high or higher fertility levels. The average value of total potassium was 0.15%~0.17%, and all soils were at low fertility levels. The results revealed the acidification trends, salinization trends and unbalanced high nutrition profiles of the greenhouse soils in east Hebei, and provided the theoretical proof for scientific nutrient management.

Key words: east Hebei, greenhouse soil, acidification, salinization, nutrition profiles
