摘　　要：[目的]为南方稻区制定水稻高产栽培措施提供理论依据。[方法]对湖北随州市曾都区培两优3076产量各构成因素进行了灰色关联度分析。[结果]各因素与水稻产量之间的关联序为每公顷穴数>每公顷有效穗数>千粒重>结实率>每穗总粒数>每穗实粒数>每穴有效穗数。[结论]在制定适宜的栽培措施时,应在适当加大种植密度的同时,提高水稻结实率和千粒重,保证水稻的高产稳产。[Objective] The theoretical basis for high-yield rice cultivation measure in southern China was provided. [Method] The gray correlation analysis of the yield structure components of rice variety Peiliangyou 3076 grown in Suizhou of Hubei Province was conducted. [ Results] The order of the correlation between the rice yield per hectare and the factors was as follows： the number of hole per hectare 〉 the number of effective panicle per hectaye 〉 1 000- grain weight 〉 seed-setting rate 〉 the number of total grain per panicle 〉 the number of filled grain per panicle 〉 the number of effective panicle per hole. [ Conclusion] In the cultivation measure-drawing up, the planting density should be appropriately increased, at the same time, the rate of seed-setting and 1000-grain weight should increased to ensure high and stable rice yield.
