黑土区四种农田防护林林地土壤质量评价

Evaluation of Soil Quality for Four Types of Shelterbelts in the Black Soil Area

  • 摘要:
    目的 研究相同林龄、不同农田防护林对林地土壤理化性质的影响,为黑土区造林树种选择、土壤质量改善提供技术支撑。
    方法 以黑龙江克山农场相同林龄(3年)的白桦(Betula platyphylla)、水曲柳(Fraxinus mandschurica)、五角槭(Acer mono)和胡桃楸(Juglans mandshurica)四种林型林地为研究对象,测定0 ~ 10、10 ~ 20、20 ~ 40 cm土层的12个土壤理化指标,在进行差异显著性检验和相关性分析基础上,采用隶属度函数和主成分分析法对土壤质量进行综合评价。
    结果 ① 与下层土壤相比,各林地表层土壤(0 ~ 10 cm)物理性质好于下层,养分含量随土层加深呈显著下降趋,但速效钾和全钾含量无明显变化规律。②不同林地间同一深度土层土壤理化性质、养分含量差异显著(P < 0.05),总体而言土壤物理性质以白桦林地、土壤化学性质以水曲柳林地最好。③ 四种林地土壤质量综合评价得分即综合质量的优劣顺序依次是水曲柳 > 白桦 > 胡桃楸 > 五角槭。
    结论 幼林阶段水曲柳和白桦林地土壤质量优于五角槭、胡桃楸林地,从培肥土壤角度考虑应优先推荐栽植水曲柳和白桦两树种。

     

    Abstract:
    Objective This paper aims to provide a technical support for the selection of tree species for afforestation and improvement of soil quality in black soil areas by studying the effects of different shelterbelts with the same stand age on the physicochemical properties of forested soils.
    Method The 3-year-old Betula platyphylla (Bp), Fraxinus mandschurica (Fm), Acer mono (Am) and Juglans mandshurica (Jm), planted at the same time in Keshan Farm, were used as the research objects. The 12 soil physicochemical indices were measured in the 0 ~ 10, 10 ~ 20 and 20 ~ 40 cm soil layers, and the soil quality was comprehensively evaluated by using the affiliation function and principal component analysis based on the significance of difference test and correlation analysis.
    Result ①The physical properties of the surface soil (0 ~ 10 cm) were better than those of the lower soil layer compared with the lower soil layer, and the nutrient contents tended to decrease significantly with the deepening of the soil layer. There was no obvious change pattern in the content of available potassium and total potassium. ② Soil physical and chemical properties and nutrient contents of the soil layer at the same depth varied significantly (P < 0.05) among different woodlands, and the best soil physical properties were found in the birch woodland and the best soil chemical properties were found in the water hyacinth woodland. ③ The overall scores for soil physical and chemical properties of different shelters were as follows: Fm > Bp >Am >Jm.
    Conclusion The soil quality of young forests of Fm and Bp was better than that of Am and Jm, and the planting of Fm and Bp should be recommended as a priority from the point of view of soil fertilization.
