木霉菌配合肥料施用对玉米产量及品质的影响

Effects of Combined Application of Trichodrema sp and Fertilizer on Yield and Quality of Corn

为玉米生产中木霉菌的科学应用及肥料的合理施用提供理论依据,研究6个不同施肥处理(T1,不施肥料;T2,常规施肥;T3,减施40%复合肥;T4,减施40%复合肥+生物有机肥;T5,常规施肥+木霉菌;T6,减施40%复合肥+木霉菌)对玉米产量与品质的影响,分析适宜鲜食糯玉米的施肥配方。结果表明:施用木霉菌可有效增加鲜食糯玉米的茎粗、穗数、叶片叶绿素含量、产量及籽粒中可溶性蛋白、可溶性糖、维生素C的含量;经济效益最高的为T6处理,其在T1基础上的新增纯收益达598.09元/667m^2,新增纯收益是T2处理的1.55倍。鲜食糯玉米生产施肥建议采用减少40%复合肥与木霉菌配施的高产优质可持续的施肥配方。

In order to provide the theoretical basis for scientific utilization of Trichodrema sp and rational application of fertilizer in corn production,the effects of six different fertilization treatments(T1,non-fertilization;T2,conventional fertilization;T3,reduction of 40%compound fertilizer;T4,reduction of40%compound fertilizer+bio-organic fertilizer;T5,conventional fertilization+Trichodrema sp;T6,reduction of 40%compound fertilizer+Trichodremasp)on yield and quality of corn are studied to analyze the suitable fertilization formula for fresh waxy corn.Result:Applying Trichodremasp can increase stem diameter,ears,leaf chlorophyll content,yield of fresh waxy corn,and soluble protein,soluble sugar and vitamin C content in kernels effectively.The economic benefit of T6 is the highest.The net income of T6 increases by 598.09 Yuan/667 m^2 compared with that of T1 and 1.55 times higher than that of T2.It is suggested to adopt the high yield,good quality and sustainable fertilization formula of reduction of 40%compound fertilizer combined with Trichodremasp in production of fresh waxy corn.
