摘要
【目的】为科学合理经营、管理农田防护林提供一定的理论依据。【方法】对新疆石河子150团不同配置农田防护林的土壤理化性质进行分析测定。【结果】防护林土壤壤土占85.71%,而黏土组仅占14.29%;农田防护林土壤容重1.3-1.51 g/cm3;pH值7.06-9.67;土壤碱解氮为14.00-56.00 mg/kg,速效磷5.12-16.30 mg/kg,速效钾68.42-500.00 mg/kg。【结论】150团土壤属于碱性土;随防护林防护年限的增长土壤容重、有机质含量得到改善,其中胡杨×沙枣模式改善效果较好;该地区防护林土壤富钾,少磷,缺氮。
【Objective】The main purpose of the study was to provide a theoretical basis for the scientific and rational management of farmland.【Method】The different arrangements of farmland shelter-belt of soil physical and chemical properties were analyzed in Shihhotze Regimental Farm 150 in Xinjiang.【Result】The results showed that the soil loam in shelter-belts accounted for 85.71%,while only 14.29% clay group;farmland soil bulk density ranged from 1.3-1.51 g/cm3;pH values ranged between 7.06-9.67;available nitrogen is 14.00 mg/kg-56.00 mg/kg;available P 5.12-16.30 mg/kg,K 68.42-500.00 mg/kg.【Conclusion】This study shows that there is only alkaline soilon Shihhotze Regimental Farm.With the growth of Shelter-belt protective soil bulk density,organic matter content was improved,and improvement of Populus × angustifolia model was better;there is rich potassium in the siol of shelter-belt,less phosphorus and lack of a nitrogen in this region.
