Shuitu Baochi Xuebao, 2018 为解决吉林省半干旱区滴灌施肥条件下氮肥合理施用问题，通过2年(2015—2016年)田间试验，研究了覆膜滴灌条件下施氮量(0，70，140，210，280，350 kg/hm2)对春玉米产量、氮素吸收利用、土壤剖面无机氮含量变化及氮素平衡的影响。结果表明：施氮量在70～210 kg/hm2范围内玉米产量随施氮量的增加显著增加，当施氮量超过210 kg/hm2后，处理间产量无显著差异；将玉米产量(y)与施氮量(x)拟合，得出最佳施氮量分别为195.1，201.0 kg/hm2 ...

Shuitu Baochi Xuebao, 2019 研究添加木质素和生物炭对土壤氮、磷养分及水分损失的影响，降低土壤改良剂使用成本，增加造纸黑液中木质素的利用途径，促进木质素在土壤改良中的应用。试验选取生物炭改良剂与木质素作为对比，通过土柱淋溶和静态吸收法，研究不同添加量（质量分数为0，1%，2%，4%）的木质素和生物炭对土壤氮磷养分、水分、脲酶活性以及pH的影响。土壤中添加木质素和生物炭均能减缓pH变化程度；抑制土壤脲酶的活性，且在添加氮肥后的1~20天抑制效果明显，其抑制效果与添加量呈正相关。添加量为1%，2%，4%的木质素和生物炭与对照组相比 ...
