摘　　要：为了验证微生物菌剂在糜子生产上的应用效果,采用大田试验的方法,以齐黍3号为试验材料,在5叶期根部灌施枯草芽孢杆菌、地衣芽孢杆菌、哈茨木霉菌、解淀粉芽孢杆菌、复合微生物菌剂和光合细菌6种微生物菌剂,以不施菌剂为对照(CK),分析不同处理对糜子农艺性状、产量性状、光合特性及土壤酶活性等指标的影响。结果表明,与CK相比,施入微生物菌剂后,土壤脲酶、蔗糖酶、中性磷酸酶活性显著增强;6种微生物菌剂均能显著改善齐黍3号的穗长、有效分蘖数、株高、茎粗等农艺性状和穗重、穗粒重、产量及净光合速率、蒸腾速率、胞间CO_(2)浓度,但对千粒重影响不显著;综合试验结果,复合微生物菌剂和光合细菌处理对提高土壤酶活性、改善糜子各生长指标效果最好,籽粒产量最高,分别比CK增产14.90%和13.45%,可应用于黑龙江省糜子大田高产栽培。In order to verify the application effect of microbial agents in the production of broomcorn millet,using the method of field test,Qishu 3 was used as the test material,and six microbial agents including Bacillus subtilis,Bacillus licheniformis,Trichoderma harziensis,Bacillus amyloliquefaciens,composite microbial agent and photosynthetic bacteria were irrigated in the root of the 5 th leaf stage,with no microbial agent as the control(CK).Agronomic traits,yield traits,photosynthetic characteristics and soil enzyme activities of broomcorn millet under different treatments were analyzed.The results showed that compared with CK,the activities of soil urease,sucrase and neutral phosphatase were significantly enhanced after the application of microbial agent.The six microbial agents could significantly improve the agronomic traits(panicle length,effective tiller number,plant height,stem diameter),yield traits(panicle weight,grain weight per panicle,yield)and photosynthetic characteristics(net photosynthetic rate,transpiration rate,intercellular CO 2 concentration)of Qishu 3,but had no significant effect on 1000-grain weight.The results showed that the compound microbial agent and photosynthetic bacteria treatment had the best effect on improving soil enzyme activity and growth indexes of broomcorn millet,and the highest grain yield,respectively increasing by 14.90%and 13.45%compared with CK,which can be applied to the high-yield cultivation of broomcorn millet field in Heilongjiang Province.
