摘要
通过对全省水稻土取样分析和进行水稻施用硅肥盆栽、田间试验。结果表明,水稻土有效硅含量高低顺序为湿潮土> 砂姜黑土> 盐化潮土> 棕壤。每666 .7m2 施用含SiO2 55% 的高效硅肥5 ～10kg,可提高土壤有效硅含量,改善水稻生物性状,增强抗逆性,与对照相比,水稻增产7-8% ～21.5% 。
Rice soil samples in plough horizon in Shandong Province were analysed,and the silicon fertilizer effects were studied through pot and field experiments.The results indicated that the available silicon content in rice soil varied in different type of soil,the sequence was as follows:Humid Fluvaquents>Vertic Haplustalfs>Saline Fluvaquents>Typic Paleustalfs.Applying high available silicon fertilizer,which contains 55% silicon dioxide, 75～150 kg per hactare could increase the available silicon content in the soil, improve the biological properties and adversity resistance of rice.The rice yield increased by 7.8%～21.5% compared with the check.
