摘要
为提高黑龙江省双城区和望奎县两个地区玉米产量,提高当地化学肥料利用效率。本文采用大区对比试验,不设重复,研究了平衡施肥技术对双城区和望奎县玉米产量和利用效率的影响。结果表明:双城示范区平衡施肥处理的玉米产量为9082.1 kg·hm-2,较对照处理增产8.28%;平衡施肥处理较对照氮肥、磷肥、钾肥利用效率分别提高了11.69%、1.00%和2.81%。望奎示范区平衡施肥处理的玉米产量为8597.3 kg·hm-2,较对照增产9.06%;平衡施肥处理较对照氮肥、磷肥、钾肥利用率分别提高了11.53%、2.03%和2.23%。
In order to improve maize yield and chemical fertilizer utilization efficiency in Shuangcheng district and Wangkui County of Heilongjiang Province.The effects of balanced fertilization on maize yield and utilization efficiency in Shuangcheng District and Wangkui County were studied in this experiment.The results showed that the maize yield of balanced fertilization treatment in Shuangcheng demonstration area was 9082.1 kg·hm-2,increased by 8.28%compared with the control,and the utilization efficiency of nitrogen,phosphorus and potassium increased by 11.69%,1.00%and 2.81%,respectively.The yield of maize of balanced fertilization treatment in Wangkui demonstration area was 8597.3 kg·hm-2,which was 9.06%higher than that of the control,and the utilization efficiency of N,P and K increased by 11.53%,2.03%and 2.23%,respectively.
