摘要

为了解设施地土壤的理化性质

以江苏省苏北地区大棚土壤为例

研究种植年限分别为1

7 a大棚土壤含水量、全N、全P、全K和重金属含量的变化情况。结果表明

随着种植年限的增加

设施地土壤含水量显著降低

随着土层深度的增加

土壤含水量进一步降低。设施地土壤全N、全P和全K含量比大田高

特别是全N和全K积累量大

且分布于耕作层

随着土层深度的增加全N和全K含量变化较大;同时

随着种植年限增加

设施地土壤全N、全P和全K含量显著增加

7 a左右的设施地土壤20 cm耕作层中的全N含量分别为1.99

1.87

2.40 g/kg;全P含量分别为1.03

1.01

1.74 g/kg;全K含量分别为1.94

3.52

4.40 g/kg

且全N和全K含量随着土层深度的增加而逐渐降低

与土层深度的变化呈显著负相关关系。随着种植年限的增加重金属含量增加

7 a左右大棚种植年限扬州和连云港地区20 cm土层中的Pb含量分别为194

225 mg/kg;淮安地区不同种植年限20 cm土层的Cd含量分别为0.80

0.93

1.14

2.49 mg/kg;扬州和连云港地区无论种植年限多久

Cr含量均大于120 mg/kg;扬...

Abstract

In order to know the physical and chemical properties of protected vegetable soil

water content

total N

K and heavy metal content in the protected vegetable soil were studied in the north of Jiangsu province with the different years of cultivation(1

7 years).The results showed that water content significantly decreased with the increase of the cultivation time and soil depth.Total N

P and K contents in the protected vegetable soil were higher than the field soil

especially total N and total K contents...
