【摘要】 为探讨液体硅肥在小麦生长发育中的作用,以济麦229为试验材料,在浇水和不浇水2种条件下开展了液体硅肥喷施试验。结果表明:不论浇水与否,施用液体硅肥均可以增强小麦植株基部节间强度,增强抗倒伏能力,增加穗数、穗粒数和千粒重,显著提高产量,且干旱情况下提高比例更高。更多还原

【Abstract】 In order to investigate the effect of liquid silicon fertilizer on wheat growth and development, using Jimai 229 as the study object, the spraying test of liquid silicon fertilizer was conducted under two conditions of watering or no watering. The results showed that regardless of watering or not, spraying the liquid silicon fertilizer could enhance the basal internode strength, thus improving the lodging resistance. The panicle number, grain number and weight could also be increased, and the yield could be significantly improved,with a higher increasing proportion under drought conditions.更多还原
