摘　　要：在滨海盐化潮土上进行夏玉米施用硅肥田间点播试验,研究夏玉米施用硅肥效果及适宜用量。结果表明,施用硅肥能够增强玉米抗病性,改善植株生物学性状和产量结构;增产效果明显,每公顷施硅肥112.5 kg增产量最高,每公顷施硅肥75 kg次之,与对照相比,增产率分别为6.64%、15.87%,每公顷纯增效益分别为916.81、127.1元。从产出投入结果看,经济最佳硅肥施用量为75-112.5 kg/hm2。The field dibbling test on salinized fluvo-aquic soil in Binhai showed that application of silicon fertilizer could enhance disease resistance of maize, improve plant biology characteristic and yield constitutes and had obvious effect of increasing yield. Application of silicon fertilizer at 112.5 kg/hm^2 could get highest yield, followed that was at 75 kg/hm^2. Compared with CK, the yield increase by these two fertilization dosages were 6.64% and 15.87%, resp. and the economic benefit increase were 61.12 and 75.14 yuan per hectare. The input and output analysis indicated that the optimum silicon fertilization dosage was 75 - 112.5 kg/hm^2.
