| 摘 要： | 在建三江挑选2家农户的田地进行硅肥试验,以龙粳31(11叶品种)为供试品种,选用两种不同的硅肥品种和不同的矿物硅肥施用量,研究硅肥对寒地水稻植株茎秆充实度、茎粗、壁厚、抗折力和产量的影响。试验结果表明:硅肥的施用可以显著提高水稻植株的茎粗、壁厚、节间充实度和抗折力,同时在一定范围内可以提高水稻产量。就产量而言,以矿物硅225 kg/hm2的施用量最适宜。

| Abstract: | We conducted the experiment of silicon in two farmers fields in Jiansanjiang regions,choosed Longjing 31 （11 leaf varieties） as the tested varieties. Research the influence of silicon to the stems plumpness of rice plants, stem diameter, wall thickness, flexural strength and yield. The experiments indicate the use of silicon can significantly increased the stem diameter of rice plants,wall thickness,stems plumpness and flexural strength,At the same time within a certain range can increase rice yield. In yield, the optimum application rate is mineral silicon 225 kg/hm2. |
