摘　　要：以特优一号为试验材料,设置2种肥料类型,3个氮素水平及3种运筹模式进行小区试验,研究不同施肥模式对水稻茎秆形态和倒伏性状的影响。结果表明:不同施肥模式对水稻抗倒性有较大影响,随施氮量增加,水稻节间长度、节间干重和水稻倒伏指数呈增加趋势。使用吉农大抗倒水稻专用肥后,水稻倒伏指数及重心高度减小,节间长度、节间干重和茎秆抗折力增加。各施肥模式水平下吉农大抗倒水稻专用肥有效增强水稻抗倒伏能力,其中在纯氮130 kg/hm2施氮量5∶3∶2运筹条件下水稻抗倒伏能力与产量优势最明显,是扎赉特旗水稻生产最佳施肥模式。Using Teyou-1 as experimental material,a plot experiment was conducted to study the effects of different fertilization modes on stem morphology and lodging traits of rice.Two fertilizer types,three nitrogen levels and three operation modes were set up.The results showed that different fertilization modes had great influence on lodging resistance of rice.Internode length,internode dry weight and lodging index of rice showed an increasing trend with the increase of N application rate.The lodging index and the height of center of gravity of rice decreased,internode length,internode dry weight and stem folding resistance increased after the application of special fertilizer for anti-toppling rice.Under different fertilization patterns,Jinongda special fertilizer for anti-collapse rice effectively enhanced the lodging resistance of rice,in which the advantage of lodging resistance and yield was the most obvious under the operation condition of N application of 130 kg/hm2at 5:3:2,and it was the best fertilizer pattern for rice production in Jalaid.
