摘要
为探求硼肥对夏玉米产量的影响和最佳用量,2013-2014年对夏玉米硼肥用量进行了多点试验研究。结果表明:在氮、磷、钾用量分别为241.5kg/hm2、81kg/hm2、82.5kg/hm2的基础上,施用硼肥7.5kg/hm2处理比习惯用肥增产891kg/hm2,增产率9.8%,增效183.15元/hm2,产投比8.1。实现玉米氮、磷、钾、硼配方施肥指导生产,可以取得明显的经济效益。
The experiment was conducted in 2013 and 2014 to explore the effect and the optimum amount of boric fertilizer for summer maize.The results showed that the yield of summer maize increased by 891kg/hm2 than usual practice when the boric fertilizer was 7.5kg/hm2 on the base, nitrogen was 241.5kg/hm2, phosphorus was 81kg/hm2 and potassium was 82.5kg/hm2, increasing yield 9.8%, economic benefit 183.15 Yuan per hectare and the production ratio was 8.1.The combined application of nitrogen, phosphorus, potassium and boric in proper ration could in- crease the economic benefits.
