【摘要】：【目的】研究生物質(zhì)炭輸入對氯化物—硫酸鹽鹽化灰漠土水分垂直運移的影響�！痉椒ā枯p、中、重鹽漬化土壤輸入不同量生物質(zhì)炭,以不添加生物質(zhì)炭為對照,通過滴加去離子水,觀測濕潤鋒和累計入滲量隨入滲時間的變化。【結(jié)果】各程度鹽漬化土壤不同生物質(zhì)炭輸入量處理,濕潤鋒垂直運移距離和累計入滲量隨入滲時間的持續(xù)均顯著增大(P㩳0.05);生物質(zhì)炭輸入阻礙水分在中、重度氯化物-硫酸鹽鹽化灰漠土入滲,低生物質(zhì)炭輸入量(≤4%)促進水分在輕度鹽漬化土壤垂直運移;輕、中度鹽化灰漠土輸入大量(≥6%)生物質(zhì)炭可增加累計入滲量,重度鹽化土壤累計入滲量隨生物質(zhì)輸入量增加而降低;不同生物質(zhì)炭輸入量處理間垂直濕潤鋒深度的累積入滲量變化無規(guī)律�！窘Y(jié)論】生物質(zhì)炭輸入比例、鹽漬化程度及兩者的交互效應(yīng)對土壤水分的入滲效率和累計入滲量均有顯著影響:對中度鹽漬化土壤入滲速率和入滲量促進作用突出;低量輸入對輕度鹽漬化土壤水分運移有促進作用;對重度鹽漬化土壤累計入滲量和入滲速率均有抑制作用。
[Abstract]:[objective] to study the effect of carbon input on vertical water migration in chlorine-sulfate ash desert soil. [methods] different amounts of biomass carbon were imported into light, medium and heavy salinized soil, and the control was not added to biomass carbon. The changes of wetting front and accumulative infiltration amount with infiltration time were observed by adding deionized water. [results] the different biomass carbon input amount of different salinized soil was treated. The vertical migration distance and cumulative infiltration amount of wetting front increased significantly with the duration of infiltration, and biomass carbon input hindered the infiltration of heavy chlorine-sulfate ash desert soil. Low biomass carbon input (鈮，
