生物炭施用对冻结期退化黑土水热盐动态变化的影响

Shuitu Baochi Xuebao
[目的] 生物炭施用可改变土壤理化性状,研究不同生物炭施用方式对土壤水、热及电导率(EC)分布的影响,可为季节性冻土科学管理提供依据。[方法] 利用田间定位试验,通过长期观测,研究东北黑土区不同生物炭施用方式对冻结期的土壤液态水含量、温度及EC的影响差异。生物炭施用方式包括一次性生物炭混施40 t/hm2(HO)、生物炭底施40 t/hm2(HE),空白为0 t/hm2(CK)。[结果] 2种生物炭施用方式均增加冻结期土壤平均液态水含量(p＜0.05),表现为HO＞HE＞CK ...

水炭运筹对黄河三角洲钠质盐土降盐效果

Shuitu Baochi Xuebao
目的为明确生物炭施加量和灌水量对黄河三角洲地区钠质盐土的降盐效果。方法采用二因子五水平正交旋转组合设计，通过土柱试验，模拟灌水量（以土壤饱和水分体积分数（θs）的1.00、1.07、1.25、1.43、1.50倍）和生物炭施加量（以0~20 cm土层土壤质量（Sw）的1.00%、1.59%、3.00%、4.41%、5.00%）对钠质盐土土壤质量含水率、电导率、pH及离子质量分数的影响，并通过层次分析法和多元回归方程综合确定最优水炭组合配比。结果1）4.41%Sw与1 ...
