摘　　要：本试验研究了不同类型品种在10.5～11.25 t.hm-2的目标产量下产量构成因素与产量的关系,为高产栽培提供理论依据。以在四川应用较多的超级稻品种和非超级稻品种为材料,研究不同类型品种连续3年高产栽培条件下的产量表现,进而分析其产量构成因素与产量的关系。研究表明:超级稻的产量与穗数、千粒重关系密切,同时,与穗粒数成显著负相关,与结实率成负相关,但未达显著水平。非超级稻品种的产量与穗数、穗粒数、结实率、千粒重呈负相关,且与穗粒数、结实率呈显著负相关。明确不同类型品种的产量构成因素与产量的关系,可以制订合理的高产栽培技术措施,充分发挥超级稻的产量潜力,实现水稻大面积稳产高产具有重要意义。The relationship between grain yield and its component was studied with different varieties under the target yield of 10.5 - 11.25 t. hm ^-2 which provided theoretical basis for high yield cultivation. Super rice and non-super rice varieties applied in Sichuan were used as tested materiels. The yield performances of different types of varieties were studied continuously under high yield cultivation for 3 years. And the relationship between grain yield and its component was analyzed. The result showed that there was a close correlation between the yield of super rice varieties and its productive panicles and 1000-grain weight, the yield of super rice varieties had a significantly negative correla- tion with gnfins per panicle, and negative correlation with seed setting rate, respoctively. Non-super rice varieties had a negative correlation with productive panicles and 1000-grain weight, and a significantly negative correlation with grains per panicle and seed setting rate, respec- tively. The conclusion revealed the relationship between grain yield and its component. According to it the high yield potential of the super rice could be improved by reasonable high yield cultivation technology measures, which would have a great significance for high and stable yield of rice in large acreage.
