摘要: 随着机械化生产水平的不断提高,水稻倒伏问题已经严重影响黑龙江省水稻生产。通过配合施用钾、硅肥和化学调控剂对防止水稻倒伏进行了初步研究,以期组装集成综合防倒伏调控技术,节省水稻生产成本、提高其产量和品质。结果表明:钾肥或硅肥单独施用时防倒伏效果不理想,硅肥(500 kg/hm222)对防倒伏有明显作用,当配合钾硅肥施用时防倒效果更好。抗倒处理降低了第1,2,3节间的长度,改善了易发生倒伏的第3节间的物理性状,增加其节间干质量和茎壁厚度。抗倒处理使每穗1,2次枝梗数增多,从而使每穗粒数增多,产量明显增加。钾硅肥与氮磷肥配合施用,并在水稻拔节前7 d喷施30%矮壮烯效剂,是一项较好的综合防倒调控栽培技术。

Abstract: With the continuous improvement of mechanization production level, rice lodging issue has seriously affect rice production of Heilongjiang province.In this paper, in order to assembly integrate comprehensive prevent lodging control technology, save the cost of rice production, improve the yield and quality, the preliminary study on combining the potassium, silicon fertilizer and chemical control agent to prevent rice lodging has carried on.Results show that when potash or silicon fertilizer applies individually, lodging resistant effect is not good.Only silicon fertil-izer (500 kg/ha)mixed with high amount of potash fertilization (400 kg/ha) has good anti-lodging effect.Chemical control agent (1.2 L/ha)has obvious effect to prevent lodging.Effect of chemical control agent cooperate with po-tassium silicon fertilizer application to prevent rice lodging is better than that of chemical control agent application.Lodging resistance reason is mainly to reduce the length of the internode 1,2,3,reducing plant height, and improved the prone to lodging third internode of physical properties, increase its internode dry weight and stem thickness.Lodging resistance treatments make yield obviously increase, mainly because increase of the primary and secondary branch number per panicle make grain number per panicle.A good comprehensive prevention regulation cultivation techniques is that potassium silicon fertilizer with nitrogen and phosphorus fertilizer application combine with spra -ying 30%chlormequat-uniconazole ME in 7 days before the jointing stage.
