摘　　要：新推宽幅梯田是实现山区农业高质量发展的重要举措,但存在土壤肥力分布不均、肥力低下、出苗困难等问题,严重制约着新推宽幅梯田效益的快速发挥。为了快速提高新推宽幅梯田的土壤肥力,采用裂区试验设计,设置0t·667^(-1)·m^(-2)、0.5t·667^(-1)·m^(-2)、1.0t·667^(-1)·m^(-2)、1.5t·667^(-1)·m^(-2)优质有机肥为主处理,以自配微生物菌剂1+NPK、商用微生物菌剂2+NPK、NPK配施和不施肥为副处理,研究不同培肥措施对紫花苜蓿生长的影响。结果表明,在施用1.0t·667^(-1)·m^(-2)或者1.5 t·667^(-1)·m^(-2)有机肥的情况下,配施微生物菌剂+NPK或者NPK均能显著改善土壤质量,促进苜蓿生长,增加苜蓿产量。The uneven distribution of soil fertility and the low fertility of newly promoted wide terraces seriously restrict the rapid development of agricultural benefits.To rapidly improve the soil fertility of the newly promoted wide terraces,this study adopted a splitplot experimental design,set 0 t,0.5 t,1 t,1.5 t organic fertilizer as the main treatment,and self-prepared microbial agent 1+NPK,commercial microbial agent 2+NPK,NPK with and without fertilization as secondary treatment,the effects of different fertilization measures on the growth of alfalfa were studied,and the results showed that in the case of organic fertilizer 1 t or 1.5 t,the application of microbial agent+NPK or NPK could significantly improve soil quality,promote the growth of alfalfa.Increase alfalfa production.
