【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%。更多还原

【Abstract】 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-P₂O₅-K₂O=26-11-12, 23-14-13 respectively） and loss-control fertilizer（N-P₂O₅-K₂O=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.更多还原
