摘要: 【目的】 研究不同产量水平下枣园土壤微生物量碳、氮与不同时期枣园土壤和植株养分的关系,为南疆红枣高产提供土壤管理的理论依据。【方法】 选取南疆高中低3种不同产量水平的枣园为研究对象,采用田间试验,研究不同时期不同产量水平下枣园土壤微生物量碳、氮与不同土层和植株氮、磷、钾养分含量之间的关系。【结果】 土壤碱解氮、速效磷含量随着土壤深度的增加逐渐降低,而速效钾含量逐渐升高。土壤微生物量碳(MBC)和土壤微生物量氮(MBD)含量之间呈极显著正相关,相关系数为0.836 7;土壤微生物量碳与骏枣展叶期0~20 cm土层速效钾含量呈显著正相关,与果实膨大期20~40 cm土层速效钾含量呈显著正相关关系。【结论】 枣园土壤微生物量碳、氮及各养分含量均保持在良好水平,土壤养分及植株养分能对微生物量碳、氮产生显著影响。

Abstract: 【Objective】 To study the relationship between soil microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) in jujube orchard at different yield levels and soil and plant nutrients in different periods can provide theoretical basis for soil management for high yield of jujube in southern Xinjiang. 【Method】 Zizyphus jujuba orchards with three different yield levels (high, middle and low) in southern Xinjiang were taken as research objects, and through field experiments, the relationship between soil microbial biomass carbon and nitrogen content of different soil layers and plant nitrogen, phosphorus and potassium in Zaoyuan at different yield levels was studied. 【Result】 The results showed that the content of soil available nitrogen and available phosphorus decreased gradually with the increase of soil depths, but available potassium content increased. The correlation between soil (MBC) and soil (MBN) was very significant and the correlation coefficient was 0.836 7. Soil MBC content was significantly and positively correlated with the content of available potassium in the 0 - 20 cm soil layer during exhibition leaf stage of jujube. Meanwhile it was showed significant great positive correlated correlation with available potassium in 20 - 40 cm soil layer during expansion period of jujube. 【Conclusion】 At present, soil MBC, MBN and nutrient content in jujube orchard were maintained at a high level and soil and plant nutrients would have significant impacts on MBC and MBN.

Key words: microbial biomass carbon; microbial biomass nitrogen; soil nutrients; plant yield
