| 摘 要： | 目的 探究3种药用植物单/混播对土壤品质的影响。 方法 以金银花Lonicera japonica (LJT)、杭白菊Chrysanthemum morifolium (CMR)、内蒙黄芪Astragalus membranaceus (AMB)为材料，以沙化裸地为对照(ck)，在豫北地区连续4 a进行定位试验。分析单/混播种植模式对不同土层(0~40 cm)中有机碳、碱解氮和土壤酶活性的影响，并分析其相关性。 结果 杭白菊/内蒙黄芪(CMR/AMB)和金银花/内蒙黄芪(LJT/AMB)混播模式下土壤有机碳、碱解氮质量分数、土壤脲酶、蔗糖酶和碱性磷酸酶活性均显著高于杭白菊(CMR)和金银花(LJT)单播模式(P＜0.05)。CMR/AMB模式下土壤有机碳质量分数较ck、CMR和AMB分别提高了29.32%、20.16%和10.25%，碱解氮质量分数较ck和CMR分别提高了28.02%和13.24%；LJT/AMB模式下土壤有机碳质量分数较ck、LJT和AMB分别提高了25.46%、18.09%和6.96%，碱解氮质量分数较ck和LJT分别提高了25.56%和11.80%。土壤有机碳、碱解氮和4种土壤酶彼此之间均呈极显著相关(P＜0.01)。从土壤剖面看，不同种植模式下土壤有机碳、碱解氮含量及4种酶活性均呈表聚性特征。 结论 LJT/AMB和CMR/AMB混播模式能通过内蒙黄芪的生物固氮作用提高土壤养分有效性，是适合在当地推广的可持续发展的生态种植模式。图2表3参28

| Abstract: | Objective]This study aims to explore the effects of single and mixed sowing of three medicinal plants on soil quality.Method]Taking Lonicera japonica(LJT),Chrysanthemum morifolium(CMR)and Astragalus membranaceus var.mongholicus(AMB)as experimental materials and sandy bare land as control(ck),the effects of single and mixed sowing patterns on organic carbon,alkaline hydrolyzable nitrogen and soil enzyme activity in different soil layers(0-40 cm)were studied in the location test conducted in northern Henan Province for 4 consecutive years,and their correlation was analyzed.Result]The content of soil organic carbon,alkali hydrolyzable nitrogen and soil enzyme activity of urease,sucrase and alkaline phosphatase under the mixed sowing patterns of CMR/AMB and LJT/AMB were significantly higher than those under the single patten of CMR or LJT(P<0.05).Soil organic carbon content in CMR/AMB pattern increased by 29.32%,20.16%and 10.25%respectively,compared with ck,CMR and AMB.Alkaline hydrolyzable nitrogen content increased by 28.02%and 13.24%respectively,compared with ck and CMR.Soil organic carbon content of LJT/AMB pattern increased by 25.46%,18.09%and 6.96%,respectively,compared with ck,LJT and AMB.Alkaline hydrolyzable nitrogen content increased by 25.56%and 11.80%respectively,compared with ck and LJT.Soil organic carbon,alkali hydrolyzable nitrogen,and four soil enzymes were all significantly correlated with each other(P<0.01).From the view of soil profile,the soil organic carbon,alkali hydrolyzable nitrogen and the activities of 4 species of soil enzymes showed the characteristics of surface aggregation under different planting patterns.Conclusion]CMR/AMB and LJT/AMB mixed patterns can improve the effectiveness of soil nutrients through the biological nitrogen fixation of A.membranaceus var.mongholicus.They are sustainable ecological patterns suitable for local promotion. |
