摘要

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、果农间作土壤容重分比人工除草别降低了15.13%，11.84%，11.18%；有机质含量增加了143.76%，7.14%，120.46%。各果农复合模式下土壤水源涵养功能指数大小依次为M1（0.64） > M3（0.59） > M2（0.51） > M0（0.38）。逐步回归分析表明，总孔隙度、容重和有机质含量是影响土壤水源涵养功能的主要因子，3个土壤因子可解释土壤水源涵养功能指数变异量的95%。通径分析表明，总孔隙度是影响土壤水源涵养功能的主要决策因素，容重是影响土壤水源涵养功能的主要限制因子。研究结果可为残塬沟壑区苹果园可持续土壤管理的选择提供科学依据。

Abstract

In order to study the effect of different fruit-crop compound managements on soil physiochemical properties and soil-water conservation in apple orchard in the gully region of plateau

and to screen dominant factors for soil-water conservation

four fruit-crop compound managements including artificial weeding (M0)

Malus-Trifolium (M1)

Malus-Wild (M2) and Malus-Zea (M3) were set up as treatments in Mafang plateau

Shaanxi Province. The differences on soil physiochemical characteristics under the treatments of four fruit-crop compound managements were compared and the soil-water conservation function was evaluated. Stepwise regression analysis and path analysis were used to explore the dominant factors affecting soil-water conservation function. The results showed that the soil physiochemical properties

such as soil density

porosity

water-holding capacity

and nutrient content in M1

M2 and M3 were higher than those of the artificial weeding plots. Among them

the soil bulk density scores of M1

M2 and M3 were reduced by 15.13%

11.84% and 11.18%

respectively

compared with the artificial weeding plot. The organic matter contents increased by 143.76%

7.14% and 120.46%

respectively. Soil-water conservation function for four fruit-crop managements was ranked as M1 (0.64) > M3 (0.59) > M2 (0.51) > M0 (0.38). Stepwise regression analysis showed that total porosity

bulk density and organic matter content were the main factors affecting soil-water conservation function. Three soil factors could explain 95% of the variation of soil-water conservation function. Path analysis showed that total porosity was the main deciding factor

and bulk density was the main limiting factor of soil water conservation function. The results of this article could provide a scientific basis for the selection of sustainable soil management in apple orchards in the gully region of plateau.
