摘要：

为了研究苜蓿、玉米和大豆3种茬口与施肥对连作大豆虫食率的影响，2003—2005年在黑龙江龙镇农场采用两因素有重复完全随机试验，3年的连作大豆虫食率结果表明，茬口主效应和施肥主效应的互作对连作大豆虫食率的影响不显著，并且二者互作的各组合虫食率变化也没有明显的规律；施肥主效应对连作大豆虫食率有显著和极显著的影响，但施肥类型和施肥量对连作大豆虫食率的影响也没有发现规律性；2003年和2004年茬口主效应对连作大豆虫食率影响不显著，但2005年茬口主效应对连作大豆虫食率有极显著影响，从3年分析结果看，大豆茬上连作大豆的虫食率都相应高于同年苜蓿茬和玉米茬上连作大豆的虫食率，说明连作大豆年分越长，虫食率有加重的趋势。

Abstract:

Effects of crop stubbles and fertilization on the percentage of seeds damaged by pest of soybean continuous cropping (SCC) was studied by completely randomized experiment in Longzhen Farm of Heilongjiang during 2003-2005. The results for 3 years showed that the interaction of the crop stubbles and fertilizations on the percentage of seeds damaged by pest of SCC had no significant influence, and the change of the percentage of seeds damaged by pest among the interaction combinations had no obviously regular either. The main effect of fertilizations on the percentage of seeds damaged by pest of SCC had significantly and very significantly influence, however, the effect of fertilizer kinds and the amounts on the percentage of seeds damaged by pest of SCC had no regular either. The stubble main effect of 2003 and 2004 on the percentage of seeds damaged by pest of SCC had no significant influence; but the one of 2005 had very significant influence. The results from the 3 year trails showed that the percentage of seeds damaged by pest of SCC in soybean stubble was all higher than that in alfalfa and maize stubble in same year, which mean the more the years of SCC get, the heavier the percentage of seeds damaged by pest happen.
