【摘要】：2016年4月,在浙江省余杭區(qū)選擇3塊相鄰的退化早竹Phyllostachys violascens林地,采用隨機區(qū)組設(shè)計,建立12個10 m×10 m的小區(qū),設(shè)置0(CK),1 500,4 500,7 500 kg·hm~(-2)生石灰用量處理。施用后7個月,測定不同生石灰用量對林地土壤酸堿度及有效態(tài)重金屬含量的影響。結(jié)果表明,生石灰的施入顯著提高了土壤p H、降低了土壤交換性酸含量(P0.05)。與對照相比,土壤p H分別提高了0.21~0.60個單位,土壤交換性酸總量、H+含量和Al~(3+)含量,分別下降了10.3%~32.2%,13.5%~32.2%,9.8%~31.3%。生石灰的施用顯著降低了土壤有效態(tài)重金屬的含量(P0.05),有效態(tài)重金屬Zn,Cu,Pb,Cd的含量分別降低了13.4%~40.5%,23.4%~49.0%,26.2%~55.0%,3.4%~46.8%。
[Abstract]:In April 2016, three adjacent degraded Phyllostachys violascens woodlands were selected in Yuhang District, Zhejiang Province. Twelve plots with 10 m 脳 10 m were set up by random block design. The effects of different dosage of quicklime on soil pH and available heavy metal content were determined. The results showed that the application of quicklime significantly increased soil pH and decreased soil exchangeable acid content (P0.05N). Soil pH increased 0.21 ~ 0.60 units, soil exchangeable acid total H content and Al~(3) content decreased by 10.3 ~ 32.22 ~ 13.5g ~ (32. 2) and 9.8 ~ 31.3 respectively. The application of quicklime significantly reduced the content of soil available heavy metals (P0.05N), and the content of available heavy metal ZnCuCuPbnb ~ (2 +) decreased by 13.4N ~ (40.5) ~ (23.49.49.0) ~ (26.2c) ~ (3.45.0) ~ 3.46.80.The content of Zn ~ (CuCu) Pb ~ (2 +) in the soil was decreased significantly by the application of quicklime, and the content of Zn ~ (CuCu) Pb ~ (2 +) CD in the soil decreased respectively.
