通过田间试验探讨了施用不同配比的配方肥对小麦产量、经济效益的影响。结果表明,18-20-7缓控释肥配方肥增产效果明显,经济效益显著,每667 m~2产量及经济效益较普通复合肥处理分别提高12.2%和102.2元。可为配方肥在小麦上合理施用提供依据和技术指导。
The effects of applying different proportion of formula fertilizer on wheat yield and economic benefits were discussed through field experiments. The results showed that 18-20-7 controlled release fertilizer had obvious effect on yield increase and significant economic benefit. The yield and economic benefit per 667 m ~ 2 increased by 12.2% and 102.2 yuan respectively compared with that of common compound fertilizer. It can provide the basis and technical guidance for the rational application of formula fertilizer on wheat.
