摘要
[目的]验证不同配方增效尿素在玉米上的肥效.[方法]以不施肥和普通尿素为对照,将添加不同增效剂配方的增效尿素1、增效尿素2对玉米进行追肥试验(共施肥4次,每次施肥量为225 kg/hm2),研究不同处理对玉米生长、籽粒产量和氮素吸收利用的影响.[结果]与不施肥处理相比,施加尿素均可显著改善玉米生物学性状,株高增加19～ 20 cm,茎粗增加0.09～0.16 cm,穗长增加1.6～5.2 cm,秃尖和颗粒不饱满玉米个数显著减少,其中以增效尿素1处理效果最佳.与不施肥处理相比,施加不同尿素处理玉米穗粒数降低,但颗粒更饱满,百粒重和鲜重均显著增加,不同尿素处理后增产6.49％～ 17.19％.与不施肥处理相比,施加尿素均可显著增加玉米氮素吸收量,且氮素表观利用率增加30.30％～54.19％.[结论]增效尿素在玉米及其他作物上具有广阔的推广应用前景.
Abstract
[Objective] To verify theefficiency of urea in different formulations of corn fertilizer.[Method] In the control of non fertilization and common urea.Dressingsynergistic urea 1 and synergistic urea 2 that add the different formula of the synergistic agent on corn dressing test (Total fertilization 4 times,each time the amount of fertilization was 15 kg/hm2).The effects of different treatments on maize growth,grain yield and nitrogen uptake and utilization were studied.[Result] The results showed that compared with no fertilization treatment,the application of urea could significantly improve the biological characteristics of maize.The plant height increased from 19 to 20 cm,the stem diameter increased from 0.09 to 0.16 cm,and the corn length increased from 1.6 to 5.2 cm,and the number of the bald tip and granule was significantly decreased,and the efficiency of thesynergistic urea 1 treatment was the best.The number of grains per ear was decreased,but the grains were more plump,the percentage of grain weight and fresh weight were significantly increased after the treatment with different urea.Increase production by 6.49％ to 17.19％,after different urea treatment.With no fertilizer treatment compared to urea could increase the uptake of Corn Nitrogen,and apparent nitrogen utilization rate is increased from 30.30％ to 54.19％.[Conclusion] Reasonable development of new urea synergistic formula has a broad application prospect in corn and other crops.
