以沈爆3号爆裂玉米新品种为试材,选用6个肥料种类对其产量、品质、生理指标、肥料成本和经济效益的影响试验进行分析。结果表明,不同肥料处理的产量和产量构成因素都有一定差异,尽管不同肥料品种的产量差异不大,但各肥料品种的成本有较大差异。综合试验结果,以单质肥自己混合的方法是高产、低本、高效益最行之有效的施肥技术和方法,产量较其它品牌的复合肥相比,增产0.6%~7.12%,肥料成本降低300元/hm2左右。
Taking Shenzhong No.3 burst new maize variety as test material, six kinds of fertilizer types were selected to test the influence on yield, quality, physiological index, fertilizer cost and economic benefit. The results showed that the yield and yield components of different fertilizer treatments all had some differences. Although the yields of different fertilizer varieties were not significantly different, the costs of different fertilizer varieties were quite different. According to the comprehensive test results, it is the most effective and efficient fertilization technique and method that high-yield, low-cost and high-efficiency are mixed by single-factor fertilizer. The output of this fertilizer is 0.6% -7.12% higher than that of other brands of compound fertilizers and the cost of fertilizer is reduced by 300 Yuan / hm2 or so.
