摘　　要：采用大田示范方法,以宝坻区老稻田为试验地块,进行常规施肥和增施钾硅钙微孔肥料的田间对比研究。结果表明:施用钾硅钙微孔矿物肥料,植株茎秆粗壮,坚硬,增强了植株的抗病虫性、抗倒伏能力;有效穗数、穗粒数、千粒质量增加,成熟期提早,增产增收效果明显。Experiments were carried out in the old rice field in Baodi district, Tianjin. Compared with conventional fertilization, microporous potassium ~＇silicon-calcium mineral fertilizer increased the diameter and hardness of stems. Stronger pest-resistance and lodging-resistance were demonstrated, higher yield with more effective panicles, grain numbers and greater grain weight, as well as earlier maturity, were found in the pot of new fertilizer. Furthermore, its income effect was also obvious.
