| 【目的】研究在液体肥料中合理复配肥料增效剂的效果,为研发多功能液体肥提供数据支撑。【方法】本试验以甜玉米作为试验材料,在大田滴灌条件下,研究了肥料增效剂芸苔素内酯(BR)、胺鲜脂(DA-6)、生化黄腐酸(BFA)与液体肥复配对甜玉米不同生长时期干物质累积、养分吸收、产量形成以及品质的影响,并分析了土壤理化性质的变化趋势。同时也研究了芸苔素内酯、胺鲜脂、生化黄腐酸对液体肥料利用率的影响。【结果】三种增效剂对液体肥的性质没有不良影响,复配施用对甜玉米的生育进程没有影响。液体肥与增效剂复配均能促进甜玉米的生长,三种增效剂对玉米鲜苞的增产效果上BFA处理表现最为明显,当BFA施用浓度为200mg/kg时增产14.36%,在所有处理中表现最佳。添加增效剂能显著增加甜玉米籽粒可溶性糖、可溶性固形物的含量,对籽粒蛋白质含量无显著影响。同时,添加增效剂BR、DA-6和BFA对肥料利用率有不同程度的促进作用,土壤有机质、碱解氮、速效磷、速效钾等含量都有不同程度的提高。【结论】BR、DA-6及BFA应用到液体肥料中,对甜玉米的生长有明显的促进作用,不断优化液体肥料中增效剂的配比在农业生产中具有良好的应用前景。 |

| 【Objective】In order to study the effects of rationally compounding fertilizer synergists in liquid fertilizers, and provide data support for the development of multifunctional liquid fertilizer 【Method】This experiment used sweet corn as the experimental material. Under the condition of drip irrigation in the field, the effects of liquid fertilizer with brassinolide (BR), amine-fresh fat (DA-6) and biochemical fulcanic acid (BFA) on the dry matter accumulation, nutrient absorption, yield formation and quality of sweet corn in different periods were studied, and the trend of soil physical and chemical properties was analyzed. At the same time, the effects of BR, DA-6 and BFA on the utilization rate of liquid fertilizers were also studied.【Result】Three synergists had no adversely affect on the properties of the liquid fertilizer, and the compound application had no effect on the growth process of sweet corn. The compounding of synergist and liquid fertilizer can promote the growth of sweet corn. The most obvious effect of three synergists on the yield increase of fresh ear is BFA treatment, when the concentration of BFA is 200 mg/kg, the yield increased by 14.36%. Adding synergist can significantly increase the content of soluble sugar and soluble solids in sweet corn, and has no significant effect on the protein content of grain. And the addition of synergist BR, DA-6 and BFA promoted the fertilizer utilization rate to varying degrees, and the contents of soil organic matter, alkali nitrogen, available phosphorus and available potassium increased to different extents. 【Conclusion】BR, DA-6 and BFA were applied to liquid fertilizers, which significantly promoted the growth of sweet corn. Optimizing the ratio of synergists in liquid fertilizers continuously will have a good application prospect in agricultural production. |
