残塬沟壑区不同果农复合模式对土壤理化性质及水源涵养功能的影响
Shuitu Baochi Xuebao, 2020 为研究残塬沟壑区苹果园不同果农复合模式下土壤理化性质和水源涵养功能并筛选出水源涵养功能主导因素。以陕西省马坊塬果-荒（M0）、果-草（M1）、果-蔬（M2）、果-粮（M3）4种果农复合经营模式苹果园为研究对象，对比4种果农复合模式土壤理化特征差异性，并评估果农复合模式对土壤水源涵养功能指数的影响。使用逐步回归分析和通径分析探讨影响土壤水源涵养功能的主导因素。结果表明：生草处理、果蔬间作、果农间作下果园土壤容重、孔隙度、持水能力、养分含量等理化性质优于人工除草样地。其中生草处理、果蔬间作 ...

Shuitu Baochi Xuebao, 2008 2003—2004年开展对9个有代表性的不同产量的苹果园秋季土壤的养分、微生物类群及土壤酶活性的研究,获得不同产量苹果园的土壤微生物生态状况。结果表明,各苹果园的土壤养分、微生物数量、多样性和酶活性均表现出较大差异。随土壤碱解氮、速效磷、速效钾、总碳含量的增加,产量水平呈增高趋势。高产园土壤微生物数量高,多数土壤酶活性强,微生物多样性好。土壤微生物中细菌数量、微生物多样性、蛋白酶、磷酸酶活性可作为评价果园土壤肥力的生物指标。果树产量与土壤微生物类群和数量具有显著正相关,与速效磷、速效钾 ...

, 2015 通过研究反事实条件句和自然律之间的关系,我们看到无论在认识论方面还是在本体论方面把自然律还原为反事实条件句都是行不通的。自然律在判别反事实条件句真假方面起着重要作用,但由于以往对自然律本质的理解存在着缺陷,所以还是很难对此论断给出一个满意的答案。这给予人们诸多启示:谨慎对待把自然律还原为其他理论的观点;反事实条件句和自然律之间的关系会变得越来越密切;需诉诸科学实践理解自然律 ...
