摘要
[目的]为验证控失肥在玉米上的应用效果，同时为控失肥配方优化和推广提供依据。[方法]开展玉米控失肥对比试验，设10个处理。[结果]玉米施用5种28-6-6控失复合肥825kg／hm^2，比等养分三元素混肥（基施）增产10．5％．20．5％，比等养分BB肥增产0．7％-9．8％。平均氮素、磷素、钾素农学利用率分别为27．4％、40．1％、76．6％。濉溪县夏玉米测土配方施肥推荐施肥量为N300kg／hm^2、P2O5100kg／hm^2和K2O45kg／hm^2。[结论]控失肥增产效果明显，肥料利用率高，值得推广。
[ Objective] The research aimed to vertify the application effects of loss-control fertilizer on maize and provide the basis for the optimi- zation and popularization of loss-control fertilizer. [ Method] The contrast trial of maize loss-control~ fertilizer was conducted. Ten treatments were arranged. [ Result] Compared with compound fertilizer with equal nutrition and BB fertilizer,the yield of 28-6-6 loss-control fertilizer 825 kg/hm^2 increased by 10.5% -20.5% and 0.7% -9.8% ,respectively. Average agronomy utilization rate of N, P and K reached 27.4% ,40.1% and 76.6%. The recommend amount of formulated fertilization in Suixi County was N 300 kg/hm^2 ,P2O5 100 kg/hm^2 and K2O 45 kg/hm^2. [ Conclu- sion] The effect of increasing yield of loss-control fertilizer is obvious, and the use efficiency is high, which is worth promoting.
