摘要
为研究硅钾肥对水稻产量的影响,特进行硅钾肥在水稻生产上的应用试验,结果表明,硅钾肥能促进茎秆壁加厚不倒伏,籽粒饱满,降低稻瘟病发生率,提高作物抗性,提高磷肥利用率和水稻结实率,改善水稻品质。水稻应用硅钾肥增产效果明显,可增产22.7～110.8 kg/667 m2,增产率达到18.8%,增收36.32～177.28元/667 m2。
The results showed that the application of silicon-potash fertilizer was able to increase the thickness of stem wall, reduce lodging, accelerate filling, lower the occurrence of blast, increase the resistance to stress, promote P fertilizer use efficiency and seed setting rate and improve rice quality. The yield and benefit could be increased by 22.7 to 110.8 kg/667 m^2 and 36.32 to 177.28 yuan/667 m^2, respectively though using silicon-potash fertilizer.
