摘要
为探索不同稳定性尿素施用量对提高玉米产量和土壤养分含量的效果,以及减施氮肥的可行性,以施用普通大颗粒尿素为对照,开展了大田试验。结果表明:与对照处理相比,施用稳定性尿素能够促进玉米的长势,在同等施氮量下,玉米长势较好;在氮素减施6.67%的条件下,稳定性尿素处理仍呈现出明显的优势,增产效果显著,土壤中铵态氮、硝态氮、有效磷、速效钾的含量较高。
In order to explore the effect of different stable urea application amount on improving maize yield and soil nutrient content,as well as the feasibility of reducing nitrogen fertilizer application,a field experiment is carried out with ordinary large particle urea as a control.The results show that compared with the control treatment,the application of stable urea can promote the growth of maize,and under the same nitrogen application amount condition,the growth of maize is better.Under the condition of reducing nitrogen application by 6.67%,stable urea treatment still shows significant advantages,with remarkable yield increase effect and higher contents of ammonium nitrogen,nitrate nitrogen,available phosphorus,and available potassium in the soil.
