为减缓黏质砂红壤沼液水分下渗,本研究以生物炭不同混掺量和不同混掺厚度为影响因子进行室内土柱模拟试验,设置3种生物炭混掺量(1%、3%和5%)和4种混掺厚度(5、10、15 cm和20 cm),同时设置不混掺生物炭为对照处...展开更多 为减缓黏质砂红壤沼液水分下渗,本研究以生物炭不同混掺量和不同混掺厚度为影响因子进行室内土柱模拟试验,设置3种生物炭混掺量(1%、3%和5%)和4种混掺厚度(5、10、15 cm和20 cm),同时设置不混掺生物炭为对照处理(CK),以探究生物炭对黏质砂红壤沼液入渗减渗效果的影响,并优选出适宜的土壤水分入渗模型。结果表明:生物炭减小了沼液灌溉下红壤的湿润峰运移速率和累积入渗量,对红...
