5种缓控释肥在玉米品种顺单6号上的应用效果

为探明缓控释肥在玉米品种顺单6号上的应用效果,以实现轻简化栽培,根据缓控释肥释放养分的特点,结合玉米精简栽培技术,采用田间试验方法,研究5种缓控释肥(金正大专家缓释肥、金正大硝基三效缓释肥、金正大控释肥、金正大硝基双效缓释肥、骅龙长效缓释肥)对玉米顺单6号的施用效果。结果表明:施用5种缓控释肥比常规施肥增产5.03%~10.82%,纯收益增加1 851.7~2 913.0元/hm~2。其中,以骅龙长效缓释肥750kg/hm~2的施用效果最好,顺单6号的产量、产值分别达7 166.92kg/hm~2和17 917.3元/hm~2,比常规施肥增产10.80%,增加纯收益2 913.0元/hm~2。施用缓控释肥能实现玉米简化栽培,同时提高其经济效益和生态效益。

Application Effects of Five Slow Controlled-release Fertilizers on Maize Cultivar Shundan 6

To explore the application effects of slow controlled-release fertilizers on the maize cultivar Shundan 6,and thus realize the light simplified cultivation,according to the nutrients releasing characteristics of slow controlled-release fertilizers,combined with the simplified cultivation techniques,a field experiment was conducted to explore the application effects of five slow controlled-release fertilizers on Shundan 6.Results:Compared with conventional fertilization,applying the five slow controlled-release fertilizers increased the yield by 5.03％～10.82％,and net income increased by 1 851.7～2 913.0 Yuan/hm2.Yield and output value of Shundan 6 applied with Hualong long-acting slow release fertilizer reached the maximum,7 166.92 kg/hm2 and 17 917.3 Yuan/hm2 respectively.10.80％ and 2 913.0 Yuan/hm2 higher than conventional fertilization.Applying controlled-release fertilizers realized simplified cultivation of maize and enhanced the economic benefits and ecological benefits as well.
