“倒伏”是小麦在高水肥条件下影响小麦品质产量的重要因素之一。在小麦生长发育时期适期喷施植物生长调节剂进行化学调控,可以有效的抑制小麦倒伏,提质促产。其具体的化控措施是: 一、多效唑化控。在小麦起身期,每667平方米喷施2001ug/ml的多效唑30公斤,可使小麦植株矮化,抗倒伏能力明显增强。并可有效的兼治白粉病和提高植株对氮素的吸收利用率。二、烯效唑化控。烯效唑(9代号S-3307,商品一般为5%可湿性粉剂)是一种高效植物生长调节剂。其生长活性比多效唑高6-10倍,在小麦拔节前7天每667 平方米喷施30-401ug/ml的烯效唑溶液50公斤,可有效的防止高密度、高水肥条件下的植株倒伏现象,并且还具有 “Lodging ” is one of the important factors that affect wheat quality and yield under the conditions of high water and fertilizer. In the period of wheat growth and development of spraying plant growth regulators during chemical regulation, can effectively inhibit wheat lodging, improve quality and promote production. The specific chemical control measures are: First, the more effective azole chemical control. In the wheat get-up period, spraying 66 kg per 667 square meters of paclobutrazol 30 kg 30 kg, wheat plants can dwarf, lodging resistance was significantly enhanced. And can effectively cure powdery mildew and improve plant nitrogen absorption and utilization. Second, the United States and physicazole control. Uniconazole (9 code S-3307, commodity is generally 5% wettable powder) is a highly efficient plant growth regulator. Its growth activity 6-10 times higher than paclobutrazol, 7 days before the jointing of wheat per 667 square meters spraying 30-401ug / ml uniconazole solution 50 kg, which can effectively prevent the high-density, high water and fertilizer conditions plants Lodging phenomenon, and also has
