摘要:
为指导玉米生产科学施肥，根据黑龙江半湿润区的土壤供肥特性、春玉米养分需求规律，在双城区、巴彦县、望奎县进行玉米施肥试验，提出施肥建议。结果表明：优化施肥处理的玉米产量平均值为8 945.0 kg?hm-2，较农民习惯施肥提高8.4%；优化施肥处理的氮、磷、钾肥利用率平均值分别为36.7%、20.8%和418%，较农民习惯施肥处理分别提高12.8%、1.8%和2.9%；优化施肥处理的氮、磷、钾农学效率平均值分别为18.2，20.3和21.3 kg?kg-1。
Abstract:
In order to guide the scientific fertilization of maize production,according to the characteristics of soil fertilizer supply and the law of nutrient demand of spring maize in semi humid area of Heilongjiang,fertilization experiments were carried out in Shuangcheng District,Bayan County and Wangkui County,and fertilization suggestions were put forward.The results showed that the average yield of maize under optimal fertilization treatment was 8 945.0 kg?hm-2.The maize yield of optimal fertilization treatment increased by 8.4%,compared with farmer accustomed fertilization.The average utilization rates of nitrogen,phosphorus and potassium under optimal fertilization treatment were 36.7%,20.8% and 41.8%.The average utilization rates of nitrogen,phosphorus and potassium increased by 12.8%,1.8% and 2.9%,compared with farmer accustomed fertilization.The average efficiency of agriculture under optimal fertilization treatment were 18.2,20.3 and 21.3 kg?kg-1.
