摘要
通过对玉米掺混肥料不同控氮比例、不同施肥量的试验研究,分析了在不同施肥量时各个氮控释比例对玉米产量的影响,确定了化肥减量增效的具体数值。综合各处理数据分析表明,供试肥料控N8%时,在对照肥料亩施用量基础上可以减少5kg,最多不能超过10kg;控N12%时,在对照肥料亩施用量基础上可减少5-10kg;控N16%时,在对照肥料亩施用量基础上可减少5-15kg;控N20%时,在对照肥料亩施用量基础上不能减少。研究结果为各玉米产区化肥减量增效施用提供了科学的依据。
Through experiment study of different nitrogen control ratio and different fertilizer amount for corn mixed fertilizer,the influence of each controlled nitrogen release ratio on corn yield with different fertilizer amount was analyzed,and specific indicators of fertilizer amount reduction and efficiency increment were determined.The experiment results showed that the amount of control fertilizer could be reduced by 5kg on the basis of control fertilizer and could be no more than 10kg,for N12%the reduction could be reduced by 5-10kg on the basis of control fertilizer,for N16%the reduction should be 5-15kg,and the amount of control fertilizer could be not reduced at N20%condition on the basis of control fertilizer.The results provided scientific references for fertilizer reduction and efficiency increase in each corn producing area.
