| 猪场废弃物Cu、Zn含量高，为了比较同源猪场废弃物（沼液、猪粪、沼渣）对土壤-生菜系统Cu、Zn迁移的影响，从广东省博罗县某规模化养猪场同时采集了猪粪、沼液与沼渣3种猪场废弃物，在Cu风险土壤中添加不同用量猪场废弃物（按每千克土壤0.1、0.2、0.3、0.4、0.5、0.6 g总氮水平计算），通过连续2茬生菜的盆栽试验来研究同源猪场废弃物对生菜可食部分Cu、Zn含量和土壤有效态Cu、Zn含量的影响。结果表明：生菜生物量受猪场废弃物种类及其处理水平2种因素的显著影响。生菜可食部分Cu、Zn含量范围分别为0.46~2.08、0.70~14.4 mg·kg-1。生菜可食部分Cu、Zn含量受猪场废弃物种类及其处理水平的显著影响，影响大小顺序为废弃物种类>废弃物处理水平；猪场废弃物提高第1茬生菜可食部分Cu含量，但降低第2茬生菜可食部分Cu含量和第1、2茬生菜可食部分Zn含量。废弃物种类对Cu影响大小顺序为猪粪 > 沼渣 > 沼液，对Zn影响大小顺序为猪粪>沼液>沼渣。猪场废弃物种类及其处理水平（两者中前者的影响大于后者）显著影响DTPA-Cu或DTPA-Zn含量，废弃物种类的影响大小顺序为沼渣 > 猪粪 > 沼液。本文供试土壤具有一定的消纳富Cu猪场废弃物的能力，富Cu猪场废弃物也适合施用到缺Cu土壤上。 |

| A pot experiment with two successive crops was conducted to investigate the effects of 3 kinds of castoffs (pig manure, biogas slurry, and biogas residue)from a large scale pig farm in Boluo county, Guangdong Province, south China, on the copper and zinc transport in the lettuce-soil system considering the high copper and zinc concentration in pig farm castoffs. According to application total nitrogen rates of 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6 g·kg-1 soil, 4 kg soil in a plastic pot was treated with 20, 40, 60, 80, 100, and 120 g of air-dried pig manure; 12, 24, 36, 48, 60, and 72 g of air-dried biogas residue; or 740, 1480, 2220, 2960, 3700, and 4440 mL of biogas slurry, respectively. All of the pig manure and biogas residue, and 40% of the biogas slurry were used as basal fertilizer, whereas 60% of the biogas slurry was top dressed. The results showed that the kinds and dosages of castoffs significantly affected the shoot biomass of lettuce with the shoot biomass of the 1st lettuce crop significantly greater than that of the 2nd lettuce crop. Cu and Zn concentrations in lettuce shoots ranged from 0.46~2.08 mg·kg-1 and 0.70~14.4 mg·kg-1, respectively. The kinds and dosages of castoffs affected significantly the Cu or Zn concentration in lettuce shoots where impact order was:kinds of castoffs > dosages of castoffs. Cu concentration in the 1st crop lettuce shoots was significantly higher than that in the 2nd crop lettuce shoots, whereas Zn concentration in the 1st crop was significantly lower than that in the 2nd crop. Castoffs increased the Cu concentration in the 1st crop lettuce shoots, but decreased the Cu concentrations in the 2nd crop lettuce shoots among which the impact order was pig manure > biogas residue > biogas slurry, and castoffs decreased Zn concentrations in the 1st or 2nd crop lettuce shoots among which the impact order was pig manure > biogas slurry > biogas residue. The kinds or dosages of castoffs significantly affected the DTPA extractive Cu or Zn concentration in soil between which the impact order was kinds of castoffs > dosages, while lettuce crops did not significantly. The contribution order among 3 castoffs to soil DTPA-Cu or-Zn was biogas residue > pig manure > biogas slurry. Soil DTPA-Cu concentration was significantly and positively correlated with dosages of pig manure or biogas residues, and soil DTPA-Zn concentration was significantly and positively correlated with dosages of biogas slurry, pig manure or biogas residue. The tested Cu-risk soil in the present paper had some capacity of Cu-enriched castoffs because of low Cu or Zn concentration in lettuce. In order to protect the ecological environment, it is necessary that Cu-enriched castoffs from large scale pig farms be applied to soil with a limited amount or low frequency, which may be a more suitable method for application of Cu-enriched castoffs to Cu-deficient soil. |
