田间小区和多点大田示范试验研究结果表明，小麦在拔节一成熟期吸收硅占全生育期吸硅总量的８８．９－９３．１％，说明小麦在生育后期吸硅力很强，因而对缺硅土壤在拔节前施硅仍有良好效果；成熟期，ＳｉＯ＿２在小麦稿秆与籽粒中的分配百分比为９４．５：５．１．施硅后，稿秆中的硅量更为增加，因而缺硅土壤上利用稿杆还田能部分缓解土壤缺硅问题。研究结果还表明，所有施肥处理均比不施肥的小麦增产极显著；在ＮＰＫ肥基础上，施７ｎ有一定增产效果；施Ｍｎ、ＺｎＭｎＳｉ＿（１）（Ｓｉ，３ｋｇ／亩），小麦增产显著：施Ｓｉ＿（２）（Ｓｉ，６ｋｇ／亩）、ＺｎＭｎ、ＺｎＭｎＳｉ＿（２）小麦增产极显著．
Field plots and field experiments showed that the absorption of silicon at the stage of jointing-maturing wheat accounted for 88.9-93.1% of the total amount of silicon absorption during the whole growth period, indicating that the silicon in the late growth stage had a strong silicon-attracting force and therefore Silica fertilization still had good effect on silicon application before jointing. At the ripening stage, the distribution percentage of SiO 2 in wheat straw and grain was 94.5: 5.1. After the silicon application, the amount of silicon in the straw increased more, so the use of man-made straw on the silicon-deficient soil could partially alleviate the silicon deficiency in soil. The results also showed that all the fertilization treatments had significantly higher yield than the non-fertilized wheat. On the basis of NPK fertilizer, the yield of 7n was increased. The yield of wheat increased significantly with Mn and ZnMnSi_ (1) (Si, 3kg / mu) Application of Si 2 (Si, 6 kg / mu), ZnMn and ZnMnSi 2 increased significantly.
