摘　　要：为探究硅锌配施对寒地水稻产量、品质及抗倒性的影响,明确高产优质的硅锌优化管理措施,采用二因素完全随机设计,进行3个硅肥水平下3个锌水平的试验研究。结果表明:A2处理水稻秧苗株高、根长差分别较对照显著提高8.0%、16.0%;A2处理地上部分与地下部分鲜重干重较对照分别提高4.8%、23.4%、0.3%、5.7%,差异达到显著或极显著水平;施硅能够提高各节间茎秆抗折力,A2处理抗倒伏指数与A1处理相比提高了15.5%。A2处理穗数、穗粒数、结实率、产量较A1处理分别提高5.3%、5.0%、6.4%、18.5%,随施锌增加穗数、产量呈增加趋势,但硅锌互作对产量及其构成因素不显著。B2、B3各节间抗折力随锌肥的施用增加而呈增加的趋势,抗倒伏指数随锌肥的施用呈增加趋势,但各处理间差异不显著。硅肥和锌肥最优指标施用量的组合为最优配比。In order to investigate the effects of combined application of silicon and zinc on yield,quality and lodging resistance of rice in cold areas,and to determine the optimal management measures for high yield and high quality of silicon and zinc,a two-factor completely random design was used to study three zinc levels under three silicon fertilizer levels.The results showed that the difference of seedling height and root length in A2 treatment was significantly increased by 8.0%and 16.0%,respectively.The fresh weight and dry weight of the upper part and the lower part of the A2 treatment were increased by 4.8%,23.4%,0.3%and 5.7%compared with the control,respectively,and the difference reached a significant or extremely significant level.Silicon application can improve the bending resistance of each internode stalk,and the lodging resistance index of A2 treatment is 15.5%higher than that of A1 treatment.Panicle number,kernel number per panicle,seed setting rate and yield of A2 treatment were increased by 5.3%,5.0%,6.4%and 18.5%,respectively,compared with A1 treatment,and the panicle number and yield showed an increasing trend with the increase of zinc application,but the yield and its constituent factors were not significant.The internode bending resistance of B2 and B3 increased with the application of zinc fertilizer,and the lodging resistance index increased with the application of zinc fertilizer,but there was no significant difference among different treatments.The combination of the optimal index application amount of silicon fertilizer and zinc fertilizer is the optimal ratio.
