摘  要:
在典型果业生产区域的黄土高原选择5个采样区的45个果园5个对照常年作物农田,利用GIS定位仪共采集0-20cm表土样品45份,对其土壤有机质含量进行了测定。果园划分为5~10a、10~15a和15a以上3个园龄段,常年作物农田选择果园附近的普通农作物田块取样。利用单样本平均数t检验和单向分组资料方差分析,对果园与农田、园龄段分组与农田2个方面进行统计分析。结果表明:果园与农田相比土壤有机质含量有一定的提高,其中大部分有显著提高;苹果优质高产地区,随果园园龄增加,土壤有机质含量显著提高,同时表明果园种草能够显著提高果园土壤有机质含量。影响果园土壤有机质含量变化原因包括肥料投入数量与结构、种植方式、土壤类型、农产品市场行情和农业技术等方面。

摘  要:
In a typical fruit production region which is involved the Loess Plateau,where 45 orchards and 5 pieces of check perennial cropland of 5 sampling plots were chosen to serve as test.By GIS the 50 samples of 0-20 cm soil layer had been collected up and the content of soil organic matter(CSOM)of these samples has been determined.The orchard years were grouped by 5~10 years,10~15 years and over 15 years and check perennial croplands were selected to be close orchard.CSOM of orchards and croplands were statistically analyzed with one-sample t test and one-way ANOVA by orchard and cropland,between cropland and different years orchard.The results show as follows:CSOM of orchard is higher than that of cropland and mostly is significant high.CSOM of orchard markedly enhanced along with orchard years increase,and growing grass in the orchard could markedly enhanced CSOM.The reasons of CSOM changing of orchard include the quantity and construction of fertilizers,planting pattern,agrotype,farm produce market and agricultural techniques and so on.
