日日橹狠狠爱欧美视频        上海交大“生物炭摻混肥料重金屬農田控污減施增效”技術報告摘要:

        在田間試驗條件下,以江蘇日日橹狠狠爱欧美视频有限公司開發生產的兩個生物炭摻混配方肥為研究對象,通過與常規復合肥對照比較,研究了生物炭摻混肥對稻田重金屬的鈍化修復與減施增效作用。結果表明,田間施用生物炭摻混肥后,土壤中Cd、As、Pb、Cr的含量均顯著低于施用常規復合肥的土壤中的含量,與農田本底背景值相當。摻混肥處理對Cd和As均表現了良好的鈍化作用,對土壤As的鈍化作用尤為顯著。與常規施肥對照相比,1號配方摻混肥處理之后水稻籽粒中Cd和As的含量分別降低了12.69%-22.91%和71.22%-94.83%,2號配方摻混肥處理后籽粒中Cd和As分別降低了10.53%-42.72%和84.44%%-91.46%。 對減施增效研究表明,與常規處理比較,1號配方及其減少施10%、15%和20%四個處理產量分別增加了5.56%,6.94%,1.39%和2.78%,2號配方及其減施四個處理產量分別增加13.89%,8.33%,6.94%和5.56%,2號配方整體產量增加率高于1號配方組處理。對產量結構的研究表明,生物炭摻混肥處理主要增加了畝有效穗和每穗粒數。生物炭摻混肥與常規復合肥比較不僅控制了重金屬的積累,而且可以提高水稻產量,在控制農田生態環境污染和化學肥料的減施增效上具有推廣應用前景。

日日橹狠狠爱欧美视频        Abstract: Under the condition of field experiment, the biochar was used to study the effects of biochar fertilizers on the contents of cadmium (Cd) and arsenic (As) in the soil by comparing with the blank control and conventional compound fertilizer. The effects of Cd and As on the enrichment of rice and the effect of reducing efficiency. The results showed that the enrichment coefficient of Cd in heavy metals was decreased by 18.77% and 44.05% respectively compared with the control, and the enrichment coefficient of As was decreased by 54.26% and 60.78% compared with the control. Significantly,The yield of rice treated with two formulations was 4.17% and 8.68% higher than that of conventional compound fertilizer treatment. Compared with conventional compound fertilizer, biochar compounding fertilizer not only controls the accumulation of heavy metals Cd and As, but also can improve the yield of rice, and has obvious advantages in controlling farmland ecological environment pollution and chemical fertilizers.
