摘要
湖北省自1987年以来开展了水稻、黄瓜、花生等作物硅肥应用研究,水稻增产4.3%-16.4%,黄瓜3.6%-9.1%,花生13.6%-40.2%,增产均达显著或极显著水平;施用硅肥能提高作物抗倒伏和抗病能力.水稻氮、硅配合施用.提高氮肥利用率2%左右.
Field experimemts of silicon fertilizers applied to rice, cucumber and peanut were started from 1987 in Hubei. Yields were increased by 4.3% - 16.4% for rice, 3.6% ~ 9. 1 % for cucumber and 13.6% - 40.2% for Peanut with significant level separately. Silicon application enhanced the resistance of rice to lodging and diseases.N-Si combined application to rice increased N fertilizer utilization ratio by about 2%, compared with that of the single N fertilizer application.
