摘  要:
通过蚯蚓养殖田间对比试验,研究蚯蚓养殖对吹填土土壤理化性质的影响。结果表明,与养殖蚯蚓的对照区相比,养殖蚯蚓的试验区土壤含盐量降低70.00%,表层土壤容重降低22.56%,非毛管孔隙度提高5.71个百分点,渗透率提高5.55 mm·h~(-1),土壤全氮、有效磷、速效钾、有机质分别提高了74.58%,230.76%,60.48%,103.80%。可见,养殖蚯蚓可有效降低吹填土含盐量,同时可有效改善土壤养分及物理结构。

摘  要:
This study aimed to explore effects of earthworms on soil physical and chemical properties in coastal dredger fill. The field comparison test was carried out through the treatment with earthworms and the treatment without earthworms. The results showed that compared with the treatment without earthworms, the treatment with earthworms could increase the soil non-capillary porosity content by 5.71 percentages, the soil permeability by 5.55 mm·h~(-1), the soil total nitrogen content by 74.58%, the available phosphorus by230.76%, the available potassium by 60.48%, the soil organic matter by 103.80%, and dicrease the soil salinity by 70.00% on average, the soil bulk density by 22.56%. In conclusion, earthworms could be dcreased soil salinity, and also could be effectively improved soil nutrient and physical structure.
