摘要
为了解黄河沿岸榆林地区枣园土壤中有机质的含量状况,采用水合热法测定了佳县和清涧两地枣园中表层土壤（0-20 cm）有机质的含量。结果表明：佳县小会坪和清涧王家河枣园土壤有机质的含量分别为9.586 g/kg和7.267 g/kg,两地均属于有机质含量偏低地,佳县小会坪有机质含量较清涧王家河稍高。随着土层深度的增加,有机质的含量逐渐减少。为陕北枣园的科学施肥和养分管理提供了一定试验依据。
In order to determine the supply of soll organic matter in jujube garden from Yellow River of Yulin, Shaanxi Province,the content of organic matter in the soil surface layer was determined by hydration-hot method in this study. The results showed that the organic matter contained in the soil from xiaohuipig garden in Jia county and wangiiahe garden in Qingjian county were 9. 586 g/kg and 7. 267g/kg, respectively. The organic matter was low-contained in these two gardens when compared to the other regions. Along with the depth, the content of organic matter decreased gradu- ally. These results provide some experimental basic for improving scientific management and fertilization of jujube garden in North of Shaanxi.
