摘要:
针对玉米主产区农民长期盲目施肥现象严重，导致氮素在土壤中积累，肥料利用率不高，造成资源浪费和环境污染，开展了玉米氮肥肥效和适宜用量试验研究。结果表明：玉米生产氮肥仍然是高产的关键因素，氮肥对玉米生长发育和产量有明显的促进作用；黑龙江省玉米生产施氮的适宜用量为N 100~180 kg·hm-2，可增产24.3%~72.9%，平均增收1 624~3 088 元·hm-2；从产量和经济效益考虑，黑龙江省玉米生产氮肥最佳用量为150 kg·hm-2。
Abstract:
Aiming at the phenomenon of long-term blind using the fertilizer，which leading to accumulation of nitrogen in the soil，low fertilizer utilization，resulting in waste of resources and environmental pollution，optimum application of nitrogen on maize was initiated.The results indicated that nitrogen fertilizer had the improve function yield on maize growth，it still was the key to high yield of maize.The appropriate amount of nitrogen in Heilongjiang province was 100～180 kg·hm-2，could increase the yield by 24.3%～72.9%，increase income 1 624~3 088 yuan·hm-2.Taking the yield and the economic benefit into account，the optimal dosage of nitrogen was 150 kg·hm-2.
