不同水稻品种适宜生态区灰色布局分析

Gray Layout Analysis of Suitable Ecological Zones of Different Rice Cultivars

[目的]针对传统的只以品种产量为唯一评判标准的局限性,采用作物品种灰色布局原理与方法,对2013年长江上游中籼迟熟组A组国家水稻品种试验汇总结果进行分析研究,为其在生产上应用提供科学依据。[方法]参试11个水稻品种分别为竹优1013、鹏两优187、泸优257、T优1655、瑞华218、内香5A/川恢907、德香047A/R4923、Ⅱ优838、天龙优1375、绿优4923、德润1A/金恢8023。试验点分布在16个地区,分别为黔东南、黔西南、贵州贵阳、贵州遵义、陕西汉中、四川巴中、四川广元、四川绵阳、四川内江、四川泸县、四川双流、云南红河、云南文山、重庆涪陵、重庆巴南、重庆万州。[结果]德香047A/R4923、绿优4923在黔东南、黔西南、贵州贵阳、贵州遵义4个区域及四川绵阳、巴南、万州具有较好的适应性,T优1655主要在四川各区试点表现良好,泸优257在贵州遵义及四川双流、泸县、文山表现具佳。[结论]该研究可为我国西南地区水稻高产优质栽培提供参考。

[Objective] The aim was to analyze the summarized results of national rice cultivars test of A group of the indica and late mature group in the upper Yangtze river in 2013 by the gray layout principles and methods of crop cultivars,according to the limitation of traditional and only taking cultivars yield as the evaluation standard,then to provide a scientific basis for its application in production.[Method] The 11 tested rice cultivars were Zhuyou 1013,Penglaingyou 187,Luyou 257,Tyou 1555,Ruihua 218,Neixiang 5A/Chuanhui 907,Dexiang 047A/R4923,Ⅱ you 838,Tianlongyou 1375,Lvyou 4923,Derun1A/Jinhui 8023,resp..The 16 tested points were the southeast of Guizhou,the southwest of Guizhou,Guiyang of Guizhou,Zunyi of Guizhou,Hanzhong of Shaanxi,Bazhong of Sichuan,Guangyuan of Sichaun,Mianyang of Sichuan,Neijiang of Sichuan,Lu county of Sichuan,Shuangliu of Sichuan,red river of Yunnan,Wenshan of Yunnan,Fuling of Chongqing,Banan of Chongqing,Wanzhou of Chongqing.[Result] Dexiang 047A/R4923 and Lvyou 4923 had better adaptability in the southeast of Guizhou,the southwest of Guizhou,Guiyang of Guizhou,Zunyi of Guizhou,and Mianyang,Banan and Wanzhou of Sichuan,Tyou 1655 showed better mainly in every tested points of Sichuan,Lvyou 257 showed better in Zunyi of Guizhou and Shuangliu,Lu county and Wenshan of Sichuan.[Conclusion] The study provides a reference for rice high yield and good quality production in Southwest area of China.
