相关分析和通径分析结果表明:“闽麦06”的有效穗数对产量的作用最大,其净贡献率达54.90%;每穗实粒数对产量的作用次之,其净贡献率为19.12%。“闽麦06”丰产(3 375~4 500kg/hm2)的产量结构为:有效穗340.8±51.0万/hm2,每穗实粒数27.2±1.48粒,千粒重43.6±3.92g。栽培试验结果表明,“闽麦06”的最适播种期为11月中下旬,适宜播种量为150.5~157.5kg/hm2,在施足基肥和三叶肥的基础上,适量施用拔节肥具有明显的增产效果。
相關分析和通徑分析結果錶明:“閩麥06”的有效穗數對產量的作用最大,其淨貢獻率達54.90%;每穗實粒數對產量的作用次之,其淨貢獻率為19.12%。“閩麥06”豐產(3 375~4 500kg/hm2)的產量結構為:有效穗340.8±51.0萬/hm2,每穗實粒數27.2±1.48粒,韆粒重43.6±3.92g。栽培試驗結果錶明,“閩麥06”的最適播種期為11月中下旬,適宜播種量為150.5~157.5kg/hm2,在施足基肥和三葉肥的基礎上,適量施用拔節肥具有明顯的增產效果。

The correlation and path analysis showed that the number of effective spike had the greatest effect on the yield of “Minmai 06”, its partial contribution rate being 54.90%, the number of filled grain per spike had secondary effect on the yield, its partial contribution rate being 19.12%. For high yield (3 375~4 500kg/hm2), the effective spikes, filled grains per spike and kilo-grain weight of “Minmai 06” should be (340.8±51.0)×104/hm2, 27.2±1.48 and 43.6±3.92g respectively. The results of cultivation test indicated that the optimum sowing date of “Minmai 06” was the last twenty days of November; the proper sowing norm was 150.5~157.5kg/hm2; under the condition of applying enough basal manure and three-leaf manure, applying shooting manure at proper dose had obvious effect norw was 150.5~157.5kg/hm2; Under the condition of increasing yield.
