根土复合体力学效应及其模型构建研究进展与展望

Shuitu Baochi Xuebao
[目的] 为探究根土复合体的力学效应机理及模型方法应用。[方法] 采用文献分析和对比分析法,归纳分析根土复合体概念和内涵、根土复合体力学效应及力学模型原理、优缺点以及适用范围。[结果] (1)根土复合体是根系与土体之间力学耦合效应的复合整体,根系在土体中交叉缠绕,起到加固作用;(2)根系与土体力学关系实质上是根土复合体土力、水力和复合力学特性作用的结果,土力特性、水力特性分别侧重研究根系对土体的影响和土中水分对土体和根系的影响,复合力学特性侧重于根土复合体自身特性对植物根系特征以及结构的直接影响 ...

耕作模式对东北黑土地大豆土壤理化特性及根系生长发育的影响

Shuitu Baochi Xuebao
目的为研究不同耕作模式对松嫩平原黑土区大豆根系生长发育和根系分泌物分泌速率的影响，明确不同耕作模式通过改变土壤理化性质和根系性状影响作物产量的差异性传递过程。方法以东北黑土区大豆品种为试验材料，设置免耕秸秆覆盖（no-tillage straw mulch， NTS）、免耕（no-tillage， NT）、深耕（seep tillage， DT）和常规耕作（conventional tillage， CK）4种耕作模式，研究其对土壤理化性质、大豆根系型态及作物产量的影响。结果1 ...
