摘要：

使用不同根瘤菌菌剂和菌肥接种紫花苜蓿中苜10号,在初花期对苜蓿分枝数、株高、根瘤数和生物量等指标进行测定,筛选提高紫花苜蓿中苜10号产量的菌剂和菌肥。结果表明,与CK组相比,ACCC 17779中华苜蓿根瘤菌菌剂5 mL(A1组)显著提升苜蓿根瘤数和地下部生物量,10 mL(A2组)显著提升苜蓿分枝数、株高、根瘤数和地下部生物量,15 mL(A3组)显著提升苜蓿地上部和地下部生物量;ACCC 17780中华苜蓿根瘤菌菌剂5 mL(B1组)显著提升苜蓿地上部生物量,10 mL(B2组)显著提升苜蓿株高、根瘤数、地上部和地下部生物量,15 mL(B3组)显著提升苜蓿地下部生物量;ACCC 03094苜蓿根瘤菌菌剂5 mL(C1组)显著提升苜蓿根瘤数和地下部生物量,10 mL(C2组)显著提升苜蓿根瘤数和地下部生物量,15 mL(C3组)显著提升苜蓿地上部和地下部生物量;华创佳农苜蓿根瘤菌剂5 mL(D1组)显著提升苜蓿根瘤数,15 mL(D3组)显著提升苜蓿地下部生物量;巧农根瘤菌肥50 mL(E1组)和100 mL(E2组)对苜蓿根瘤数和根长提升较为显著,150 mL(E3组)对苜蓿分枝数、根长、地上部和地下部生物量提升较为显著;以上药剂选取合适浓度可作为紫花苜蓿中苜10号菌剂和菌肥开发的主要原料使用,综合来看巧农根瘤菌肥较其他药剂成本更低,更具有性价比。

Abstract:

Different rhizobia fungicide and fertilizer were used to inoculate Medicago sativa L.cv.Zhongmu 10, and the indicators of branching number, plant height, number of root nodules and biomass of Medicago sativa L. were measured at the early flowering stage to screen the fungicide and fertilizer that could improve the yield of Medicago sativa L.cv.Zhongmu 10. The results showed that, compared with the CK group, ACCC 17779 Chinese alfalfa rhizobia fungicide 5 mL (group A1) significantly increased the number of root nodules and underground biomass of Medicago sativa L., 10 mL (group A2) significantly increased the number of branches, plant height, the number of root nodules and underground biomass of Medicago sativa L.,15 mL (group A3) significantly increased the aboveground and underground biomass of Medicago sativa L.ACCC 17780 Chinese alfalfa rhizobia fungicide 5 mL (group B1) significantly increased the aboveground biomass of Medicago sativa L.,10 mL (group B2) significantly increased plant height, number of root nodules, aboveground and underground biomass of Medicago sativa L., and 15 mL (group B3) significantly increased underground biomass of Medicago sativa L. ACCC 03094 alfalfa rhizobial fungicide 5 mL (group C1) significantly increased the number of root nodules and underground biomass of Medicago sativa L, 10 mL (group C2) significantly increased the number of root nodules and underground biomass of Medicago sativa L., 15 mL (C3 group) significantly increased aboveground and underground biomass of Medicago sativa L. Huachuangjianong alfalfa rhizobia fungicide 5 mL (group D1) significantly increased the number of root nodules, 15 mL (group D3) significantly increased underground biomass of Medicago sativa L. Qiaonong rhizobia fertilizer 50 mL (group E1) and 100 mL (group E2) significantly increased the number of root nodules and root length, and 150 mL (E3 group) significantly increased the number of branches, root length, and aboveground and underground biomass of Medicago sativa L.. The above agents can be used as the main raw materials for the development of fungicide and fertilizer with the appropriate concentration for Medicago sativa L.cv.Zhongmu 10; Overall, Qiaonong rhizobia fertilizer has a lower cost and better cost-effectiveness compared with other agents.
