摘要
以春小麦品种“永良15号”为材料,于2022年和2023年开展大田试验。试验设置在拔节期、孕穗期和花后5 d喷施硅肥,以不施用硅肥为对照(CK),分析了小麦白粉病的病情指数、产量及籽粒品质。研究结果表明,拔节期和孕穗期喷施硅肥对小麦白粉病发生具有抑制作用,以拔节期喷施效果最好。拔节期和孕穗期喷施硅肥能够显著增加小麦产量,拔节期喷施硅肥还能够增加小麦蛋白质和淀粉含量,提升小麦加工品质。综上所述,本试验条件下拔节期喷施硅肥对降低白粉病发生、提升小麦产量和品质效果最好。
Field experiments were conducted in 2022 and 2023 using the spring wheat variety Yongliang 15 as the experimental material.Four treatments were applied:no silicon fertilizer(CK),spraying silicon fertilizer at the jointing stage(JS),spraying silicon fertilizer at the booting stage(BS),and spraying silicon fertilizer five days after anthesis(HS).The study examined the prevention and control of wheat powdery mildew and its impact on grain quality under field conditions.The results indicated that spraying silicon fertilizer during the jointing and booting stages had an inhibitory effect on the occurrence of wheat powdery mildew,with the jointing stage showing the most effective results.Spraying silicon fertilizer during these stages significantly increased wheat yield.Spraying silicon fertilizer at the jointing stage enhanced wheat protein and starch content,thereby improving grain quality.In conclusion,under the conditions of this experiment,spraying silicon fertilizer during the jointing stage has the greatest effect in reducing the occurrence of powdery mildew while improving wheat yield and quality.
