为探明高效硅钾肥阿瑞斯在水稻增产、增效上的应用效果,试验于江淮里下河稻区开展了水稻高效硅钾肥喷施试验。研究结果表明,喷施高效硅钾肥阿瑞斯能优化水稻产量构成,改善水稻生育后期熟相,提高抗病特性,能增产水稻1.9%~6.1%,其中于分蘖期、拔节孕穗期和齐穗期协同喷施增产效果最为明显,增产幅度为5.5%~6.1%。 In order to find out the application effects of high-efficiency silicon-potash Ares on the yield and efficiency of rice, the high-efficiency potash and potash fertilization experiment on paddy rice in Jianghuai Xiahe rice area was carried out. The results showed that spraying high efficient silicon potash Ares could optimize the rice yield composition, improve the late phase of rice growth and improve disease resistance, increase the yield of rice by 1.9% ~ 6.1%, including tillering, booting and booting The synergetic effect of synergetic spraying was the most obvious, with the increase rate of 5.5% -6.1%.
