摘　　要：以国家黄淮海区域对照品种冀豆12为供试材料,研究了控释复合肥对高蛋白大豆农艺性状、干物质积累、产量及效益的影响。结果表明,与常规复合肥(CK)相比,不同用量控释复合肥施用后植株各性状均得到改善。相比CK,300和375 kg/hm^(2)控释肥处理下,植株株高、根长和有效荚数显著增加;植株总干重增加幅度分别为24.84%、26.28%,豆荚干重增幅最大,分别为30.96%、32.63%;产量增幅分别为20.40%、18.65%,主要体现在单株荚数和粒数上;经济效益分别增收3325.83、2777.36元/hm^(2)。表明控释复合肥在大豆上的施用可行有效。鉴于300和375 kg/hm^(2)处理间无显著差异,考虑到降低肥料成本,300 kg/hm^(2)控释肥处理可作为相似生态条件下大豆生产中的推荐施肥方式。The effects of controlled-release compound fertilizer on agronomic traits,dry matter accumulation,yield and benefit of high-protein soybean were studied with Jidou 12,a national Huang-Huai-Hai regional control variety.The results showed that compared with the conventional compound fertilizer(CK),the plant properties were improved with different dosage of controlled-release compound fertilizer.Compared with CK,300 and 375 kg/hm^(2) controlled-release fertilizers significantly increased plant height,root length and effective pod number,the increase rate of plant dry weight was 24.84%and 26.28%respectively,and the increase rate of pod dry weight was 30.96%and 32.63%respectively.The yield increased by 20.40%and 18.65%respectively,which was mainly reflected in the number of pods per plant and the number of seeds per plant,and the economic benefit increased by 3325.83 and 2777.36 yuan/hm^(2) respectively.The results showed that the application of controlled-release compound fertilizer on soybean was feasible and effective.Considering no significant difference between 300 and 375 kg/hm^(2) treatments and reducing fertilizer cost,300 kg/hm^(2) controlled-release fertilizer treatment could be used as the recommended fertilization method in soybean production under similar ecological conditions.
