通过无土栽培试验,着重研究小麦吸收硅素养分的规律.以及小麦对硅肥使用的效应。结果表明:(1)小麦施用硅肥,与水稻一样具有显著增产效果,(2)小麦植株体内各部位SiO_2含量为叶>茎>穗;(3)小麦出苗至拨节期是吸收硅素养分高峰期,因而在相同施肥量条件下,出苗至拨节期是硅肥施用的最佳时期,千粒重增加最多。比对照增加3.43克(10.63%)。 Through soilless cultivation experiments, we focus on the law of wheat nutrient absorption of silicon, and the effect of wheat on the use of silicon fertilizer. The results showed as follows: (1) The application of silicon fertilizer in wheat had the same effect of yield increasing as that of rice. (2) The content of SiO_2 in all parts of wheat was leaf> stem> spike; (3) Peak, so the same amount of fertilizer conditions, the seedling to dial-off period is the best period of silicon fertilizer application, 1000-grain weight increase the most. An increase of 3.43 grams (10.63%) over the control.
