不同肥料配施对复垦土壤团聚体及有效磷含量的影响
Effect of soil aggregate and available phosphorus content of reclamation soil with application of three fertilizers
摘要
Abstract
[Objective]This paper is to seek the best fertilizing model of reclamation soil in the collapse mining area.[Methods]Explores the effect soil aggregate and available phosphorus content of reclamation soil with application of manure fertilizer,chemical fertilizer and bacterial fertilizer,based on long-term experiment in the coal subsidence area in Xiangyuan County,Changzhi City,Shanxi Province.[Results]It showed,compared with other treatment,that the soil aggregate quantity in the size was bigger than 5.00 mm decreases sharply in the soil with application of three fertilizers,while it had considerable increase in the size of 0.25<d≤0.50 mm and 0.50<d≤1.00 mm.At the same time the available phosphorus content and corn yield increased apparently,which increased 0.51-4.88 mg·kg-1 in available phosphorus content of reclamation soil,0.13-4.78 mg· kg-1 in available phosphorus content of different sized aggregate and 24.04-2 524.90 kg·hm-2in corn yield.The soil aggregate content decreased by 0.93%-21.78%,in size of bigger than 5.00 mm,but the soil available phosphorus content increased by 62.03%-13.36% and the soil available phosphorus content in different size of soil aggregate increases by 69.18%-3.92% in the soil with application of bacterial fertilizer compared with no bacterial fertilizer.The soil aggregate in the size between 2.00<d≤5.00 mm contributed highest to the soil available phosphorus content,while it showed the lowest in the size of bigger than 5.00 mm.As the increases of reclamation years,the soil aggregate content declined significantly in the size of bigger than 5.00 mm,while the soil available phosphorus content and corn yield increased considerably.[Conclusion]In conclusion,the soil with application of three fertilizers could reduce the soil aggregate content of big size,and rised the soil available phosphorus content and corn yield,in coordinated with harrowing,leveling and repressing in spring drought season,it could be used as the best optimal model of reclamation soil in the mining subsidence area.关键词
