摘要

为了解黄土丘陵区雨养条件下山地果园有机材料结合集雨措施（organic materials combined with rainwater collection measures，OMR）对苹果园土壤理化性质的影响，2016年4月在陕西延安山地苹果园，以果树树冠投影面反坡修建鱼鳞坑和集雨坑，研究了有机材料用量分别为5 250 kg/hm2（OMR1），4 500 kg/hm2（OMR2），3 750 kg/hm2（OMR3），0 kg/hm2（CK）以及传统处理T对苹果园土壤理化性质的影响，测定了0—300 cm土层土壤含水率和土壤电导率，0—200 cm土壤土层硝态氮含量和0—100 cm土层土壤容重和饱和导水率。结果表明：有机材料结合集雨措施能够显著增加果园0—300 cm土层土壤含水率，OMR2处理土壤平均含水率增加最显著，有机材料结合集雨措施处理（OMR1、OMR2、OMR3）的土壤根系湿润区主要集中在0—100 cm土层。0—300 cm土层OMR2处理土壤多次平均含水率值最高，为14.87%；OMR1、OMR3、CK和T处理的土壤多次平均含水率分别为14.74%，14.80%，12.79%和8.66%。有机材料结合集雨措施处理能够显著增加0—200 cm土层土壤硝态氮含量，尤其增加40—100 cm土层土壤的硝态氮含量；有机材料结合集雨措施能够显著降低土壤容重，尤其是20—60 cm土层的土壤容重；有机材料结合集雨措施能够增加土壤饱和导水率，尤其增加0—40 cm土层土壤的饱和导水率；有机材料结合集雨措施能够增大土壤的电导率，并且峰值出现在60—100 cm土层中，0—300 cm土层土壤电导率呈现OMR2 > OMR1 > OMR3 > CK > T。总体而言，在陕西延安采用有机材料结合集雨措施能够显著提高山地苹果园土壤含水率和土壤硝态氮含量，降低土壤容重，增大饱和导水率和电导率，使果树在适宜的环境中生长，促进当地山地果业可持续发展。

Abstract

In order to explore the effects of organic materials combined with rainwater collection measures (OMR) on soil physicochemical properties of apple orchard under rain-fed conditions on the Loess Plateau

apple orchards in Yan'an of Shaanxi Province were selected to conduct the experiments in April 2016. Fish scale pit and rain-collecting pit were conducted on the reverse slope of crown projection surface of apple trees

and the effects of different dosages of organic materials (5 250 kg/hm2 (OMR1)

4 500 kg/hm2 (OMR2)

3 750 kg/hm2 (OMR3) and 0 kg/hm2 (CK)) and traditional treatment (T) on soil physicochemical properties were studied. Soil water content and electrical conductivity in 0-300 cm soil layer

nitrate nitrogen content in 0-200 cm soil layer and soil bulk density and saturated hydraulic conductivity in 0-100 cm soil layer were determined. The results showed that OMR could significantly increase the soil moisture content in 0-300 cm soil layer

and the average soil moisture content increased most significantly in OMR2 treatment. The soil root wetting areas in OMR1

OMR2 and OMR3 treatment were mainly concentrated in 0-100 cm soil layer. In the 0-300 cm soil layer

the multiple average moisture content of OMR2 treatment was the highest (14.87%)

while that of OMR1

OMR3

CK and T treatment was 14.74%

14.80%

12.79% and 8.66%

respectively. The OMR could significantly increase the content of nitrate nitrogen in 0-200 cm soil layer

especially in 40-100 cm soil layer. The OMR could significantly reduce soil bulk density

especially the bulk density of 20-60 cm soil layer. The OMR could increase soil saturated hydraulic conductivity

especially in 0-40 cm soil layer. The OMR could increase soil electrical conductivity

and the peak value appeared in 60-100 cm soil layer

and the electrical conductivity of 0-300 cm soil layer followed the order of OMR2 > OMR1 > OMR3 > CK > T. Overall

the OMR in Yan'an

Shaanxi could significantly improve soil moisture content

and nitrate nitrogen content

soil saturated hydraulic conductivity and electrical conductivity

reduce soil bulk density

with make fruit trees grow in suitable environment and promote sustainable development of local fruit industry.
