杂交水稻引种对温、光、生育期的灰色关联度分析

The Mating the Paddy Rice Introduction to Grow to Temperature, Light, Grow the Period's Analysis of Gray Connection Degree

试用灰色系统理论关联度法对今年杂交稻引进的7个品种进行产量、大于10℃有效积温、日照数的灰色关联度分析,分析结果表明:不同品种产量与温、光、生育期的关联度不同;同一品种产量与温、光和生育期的关联度也不同,其关联顺序为:日照数(r3=0．9786)>生育期(r1=0．6972) >积温(r2=0．4371),在水稻引种过程中,本地每年日照数和大于10℃积温都比较恒定,应注意选择感光性强、生育期适度、感温性不强的品种。

Try out the method of gray system theories connection degree right this year the Mating the paddy rice 7 species of the yield, larger than 10℃ validity accumulate temperature, Sunshine number, analysis result enunciation： Connection degree that different species yield and temperature, light, grow the period of different; The same species yield and temperature, light, grew the period＇s is different from connection degree too, sequence of its connection is： Sunshine number（r3=0,9786）） Grow the period＇s（r1=0.6972）） Accumulate the temperature（r2=0.4371）, in the paddy rice introduction in the process, native every year sunshine number with the larger than 10℃ accumulate the temperature to all compare the invariable, and should notice the choice to exposed to light the sex strongly, growing the period within limit, feel the temperature not strong
