摘要
在同等养分投入条件下,于山东省泰安市研究了6种缓控释肥对玉米养分吸收、氮肥利用率及产量的影响。结果表明:自制缓释氮肥A和众德掺混肥料-多功能长效肥具有较好的增产、增效作用,主要通过增加穗粒数、千粒重、籽仁中钾含量及秸秆中氮、磷、钾含量达到增产效果,分别比常规尿素处理增产15.16%和10.42%;在不同缓控释肥处理中,以自制控释氮肥A处理的玉米氮肥利用率最高,比常规尿素处理增加了58.25%。初步确定自制缓释肥A和众德掺混肥料-多功能长效肥为适合当地土壤条件及玉米栽培的缓控释肥品种。
In order to explore the effects of different kinds of slow and release fertilizers on maize fertilizer saving and yield increasing,six kinds of slow and release fertilizers were studied under the same nutrient input conditions in Tai’an City,Shan?dong Province.The results showed that the self-made slow-release fertilizer A and Zhongde Mixed Fertilizer-Multifunctional Long-acting Fertilizer had better effect on increasing yield and synergy,mainly by increasing the number of grains per spike,1000-grain weight,potassium content in kernels and nitrogen,phosphorus and potassium content in straw,which increased yield by 15.16%and 10.42%respectively compared with conventional urea.The self-made controlled-release nitrogen fertilizer A had the highest utilization rate of nitrogen fertilizer,which could increase 58.25%compared with conventional urea.It was preliminarily determined that the self-made controlled-release nitrogen fertilizer A and Zhongde Mixed Fertilizer-Multifunctional Long-acting Fertilizer were suitable for local soil conditions and maize cultivation。
