【摘要】：為了探討生物質(zhì)炭對(duì)黑土吸附-解吸硝態(tài)氮性能的影響,減少黑土中硝態(tài)氮的淋失、提高氮肥利用率以及為農(nóng)業(yè)廢棄物資源化利用提供理論依據(jù),采用培養(yǎng)試驗(yàn),應(yīng)用Langmuir方程和Freundlich方程,研究了添加不同來源(玉米秸稈、稻殼、松木)和不同添加比例(0.6%、1.2%、3.6%、6%)生物質(zhì)炭對(duì)黑土中硝態(tài)氮(NO_3~--N)的吸附和解吸特征。結(jié)果表明,施用生物質(zhì)炭可增加黑土對(duì)NO_3~--N的吸附量,且三種生物質(zhì)炭的添加比例為3.6%時(shí),土壤對(duì)NO_3~--N的吸附量最大;施用玉米秸稈生物質(zhì)炭的黑土對(duì)NO_3~--N的吸附量最大(實(shí)際最大吸附量為0.929 mg·g~(-1)),施用松木生物質(zhì)炭的黑土對(duì)NO_3~--N的吸附量最小(實(shí)際最大吸附量為0.578 mg·g~(-1))。施用生物質(zhì)炭可降低黑土對(duì)NO_3~--N的解吸率,且三種生物質(zhì)炭的添加比例為3.6%時(shí),土壤對(duì)NO_3~--N的解吸率最低;添加玉米秸稈生物質(zhì)炭的黑土對(duì)NO_3~--N的解吸率最低,添加松木生物質(zhì)炭的黑土對(duì)NO_3~--N的解吸率最高。不同生物質(zhì)炭對(duì)NO_3~--N的吸附能力表現(xiàn)為玉米秸稈稻殼松木;對(duì)其解吸能力表現(xiàn)為玉米秸稈稻殼松木。生物質(zhì)炭及添加生物質(zhì)炭的黑土對(duì)NO_3~--N的吸附過程符合Langmuir方程。
[Abstract]:In order to study the effect of biomass carbon on the adsorption and desorption of nitrate nitrogen in black soil, reduce the leaching loss of nitrate nitrogen in black soil, improve the utilization rate of nitrogen fertilizer and provide theoretical basis for the utilization of agricultural wastes, the cultivation experiment was carried out. Langmuir equation and Freundlich equation were used to study the adsorption and desorption characteristics of no _ 3-N _ 3-N in black soil by adding different sources (corn straw, rice husk, pine wood) and adding 0.6 ~ (1.2) and 3.6cm ~ (-6) carbon to black soil by using Langmuir equation and Freundlich equation. The results showed that the application of biomass carbon could increase the adsorption capacity of No3 N on black soil, and when the addition ratio of three kinds of biomass carbon was 3.6, the adsorption capacity of soil to NO3 N was the largest. The black soil with corn straw biomass carbon has the largest adsorption capacity of NO3C N (the actual maximum adsorption capacity is 0.929 mg / g ~ (-1), and the black soil applying biomass carbon of pine wood has the smallest adsorption capacity of no ~ (3-) N (the actual maximum adsorption capacity is 0.578 mg / g ~ (-1). Applying biomass carbon can reduce the desorption rate of NO3- + -N in black soil, and when the addition ratio of three kinds of biomass carbon is 3.6%, the desorption rate of NO3- -N in soil is the lowest, and the desorption rate of NO3- -N is the lowest in black soil added with biomass carbon of corn straw. The black soil added with pine biomass carbon had the highest desorption rate of NO3- N. The adsorption ability of different biomass carbon to no _ 3-N was shown as corn straw rice husk pine wood, and its desorption ability was corn straw rice husk pine wood. The adsorption process of no _ 3- N on the black soil containing biomass carbon and biomass carbon is in accordance with Langmuir equation.
