| 摘 要： | 通过田间试验,研究不同长效复合肥对玉米产量及施肥效率的影响。试验结果表明施用一次深施复合肥比追施尿素增产,增产幅度为5.2%~9.8%。同时比一次深施加长效剂的尿素更增产。深施长效复合肥能提高玉米的生长势,同时降低玉米的空秆率。施用玉米一次深施复合肥能提高肥料的利用率,特别是提高氮肥的利用率;能提高经济效益,可增收507.7元/hm2。

| Abstract: | The effect of different slow-release compound fertilizer on the maize yield and fertilizer efficiency was studied by field trial. The results showed that compared with dressing urea, the yield of maize applied deeply with compound fertilizer increased by 5.2%-9.8%, which could improve growth potential of maize, reduce rate of empty stem, improve fertilizer efficiency, especially, efficieny of nitrogen fertilizer. Income of peasant increased 507.7 yuan per hectare. |
