摘要:

为考察在常规施底肥的基础上,追施含螯合微量元素尿素对玉米植株生长及果实成熟的促进作用,开展了田间小区试验。试验设4个处理,以施普通尿素为空白对照,测定了玉米在各生育时期的指标。结果表明:玉米施用螯合钾锌尿素、螯合锌硼尿素、螯合钾加锌尿素等新型尿素后,株高、茎粗、叶长、叶宽、穗长、穗粗、穗粒数、百粒质量等生物学性状和经济性状都明显优于施用普通尿素的;施用3种含螯合微量元素尿素的玉米产量比施用普通尿素的增产6.52%~9.31%,增加收益50.35~74.06元/亩(1亩=667 m2)。

Abstract:

In order to investigate the promotion effect of urea containing chelated trace elements as topdressing on maize plant growth and fruit ripening based on conventional bottom fertilizer application, a field plot experiment is conducted. Four treatments are set up in the experiment, with common urea as the blank control, and the indicators of maize at different growth stages are measured. The results show that the application of new urea such as chelated potassium zinc urea, chelated zinc boron urea, and chelated potassium plus zinc urea in maize resulted in significantly better biological and economic traits such as plant height, stem diameter, leaf length, leaf width, ear length, ear diameter, number of grains per ear, and hundred grain weight compared to the application of common urea. The application of three types of urea containing chelated trace elements increased the yield of maize by 6.52% to 9.31% compared to the application of common urea, and increased the income range is 50.35 to 74.06 yuan/mu (1 mu=667 m2).
