鲜食玉米轻简化施肥技术

Light simplified fertilization technology for fresh maize

针对当前鲜食玉米生产中施肥环节存在费工费时等现状,该研究采用有机肥料+普通肥料混合施用,缓释尿素替代普通尿素的方式开展鲜食玉米轻简化施肥技术研究。结果表明:有机肥与缓释尿素在鲜食玉米生产中的施用效果较好,在促进果穗商品性、提高肥料利用效率与节省人工等方面发挥了显著作用。不同品种鲜食玉米对肥料的需求有所差异,在生产中要注重良种配良法,围绕品种开展配套栽培技术研究。2个品种在每667 m^(2)使用120 kg商品有机肥、50 kg三元复合肥(N 17%,P_(2)O_(5)17%,K_(2)O 17%)、10.45 kg缓释尿素一次性基施、无须追肥的情况下均取得较高的产量与收益,在实际生产中可以用于指导鲜食玉米轻简化施肥。

In view of the current situation of labor-intensive and time-consuming fertilization in the production of fresh maize,this study used the mixture of organic fertilizer+ordinary fertilizer and the replacement of ordinary urea with slow-release urea to carry out the research on light and simplified fertilization technology of fresh maize.The results showed that the application effect of organic fertilizer and slow-release urea in the production of fresh maize was good,and it played a significant role in promoting the commercialization of ears,improving fertilizer use efficiency and saving labor.Different varieties of fresh maize have different requirements for fertilizer,so it is necessary to pay attention to the good cultivation techniques with the varieties.The two varieties achieved high yields and benefits under the condition of using 120 kg of commercial organic fertilizer,50 kg of ternary compound fertilizer(N 17%,P 2O 517%,K_(2)O 17%)and 10.45 kg of slow-release urea per 667 m^(2)without topdressing.
