摘　　要：为明确缓释掺混肥和控失肥的增产效果,总结了中盐安徽红四方肥业股份有限公司生产的缓释掺混肥(N-P2O5-K2O分别为26-11-12、23-14-13)和控失肥(N-P2O5-K2O为26-10-12)在13个农场开展的玉米大田示范试验情况。结果表明:与常规施肥处理相比,施用两种缓释掺混肥处理的玉米穗长分别增加0.2~2.4 cm和0.1~2.5 cm,行粒数分别增加1~4粒和0~3粒,平均增产率分别为3.9%和3.8%;与常规施肥处理相比,施用控失肥处理的玉米穗长增加0.1~1.8 cm,行粒数增加1~8粒,平均增产率为5.6%。In order to clarify the yield increasing effects of slow release bulk blending fertilizer and loss control fertilizer,the demonstration experiments of slow release bulk blending fertilizers(N-P 2O 5-K 2O=26-11-12,23-14-13 respectively)and loss-control fertilizer(N-P 2O 5-K 2O=26-10-12)produced by Anhui Hongsifang Co.,Ltd.in 13 maize fields are summarized.The results show that comparing with conventional fertilization treatment,the maize ear length increased by 0.2-2.4 cm and 0.1-2.5 cm,and the number of grains per row increased by 1-4 and 0-3,respectively,when treated with two slow release bulk blending fertilizers.The average yield increase rates are 3.9%and 3.8%,respectively.Compared with conventional fertilization treatment,the maize ear length increase by 0.1-1.8 cm and the number of grains per row increase by 1-8,with an average yield increase of 5.6%,when treated with loss-control fertilizer.
