摘　　要：采用大田小区试验研究不同有机无机肥配比对湘杂油763生长和产量的影响。结果表明:纯无机肥处理的产量最高,为2 628.40 kg/hm2,且与40%OM处理、不施肥处理的差异达到显著水平。4个施用有机肥处理间差异不显著,以20%OM处理产量较高,为2 229.20 kg/hm2。当有机肥用量超过20%时,油菜籽粒产量随着有机肥用量的增加而减少。收获期的经济性状和农艺性状有较好的规律,其中每角果粒数和单株干重与产量变化规律相似,与产量间有较好的相关性,相关系数达到0.813和0.993**。因此,收获期单株干重较好地反映籽粒产量情况,且20%OM处理为最佳有机无机肥配合比例。A field experiment was conducted to study the effects of different proportions of organic fertilizer and inorganic fertilizer on yield and growth of Xiangzayou763.The results showed that the treatment of pure inorganic fertilizer had the highest yield by 2 628.40 kg/hm2,and had significant differences with treatments of 40% of OM and non-fertilizer;four treatments of organic fertilizer had no significant difference,in which the 20% of OM had the highest yield by 2 229.20 kg/hm2;when organic fertilizer rate was more than 20%,the rapeseed yield decreased with increasing organic fertilizer rate;the economic characters and agronomic characters in harvest period had good law,in which the grain number per spike and the dry weight per plant had the same variation law with yield＇s,and had good correlation with yield,the correlation coefficient of the grain number per spike and the dry weight per plant was 0.813 and 0.993＊＊,respectively.Therefore,the dry weight per plant in harvest period can reflect the grain yield greatly,and the 20% of OM treatment was the best compound proportion of organic fertilizer and inorganic fertilizer for Xiangzayou763.
