| 摘 要： | 本文以棉花主茎展开叶数表示生育进程,研究了展叶进程与干物质积累、株高增长、倒四叶宽变化及果节量、现蕾强度等生长指标的关系。结果表明,这些指标随展叶进程均呈有規律的变化;同播期条件下,不同品种类型间差异不大,而不同播期间,差异较大;展叶进程与生育期、株高增长等生育指标相比较,稳定性较好。更能科学地反映棉花生长发育规律,并便于指导生产。

| Abstract: | The relationships between the number of leaf expansion on the main stem and the accumulation of dry matter(DMA),the increase of main setm(MSI),the width of the fourth expanded leaf from terminal one(WFFL),the number of fruit node on the plant(FNN)and the intensity of cotton bud appeared(CBI)were studied in this paper.The results showed that the equations on the relationship between leaf expansion and DMA,MSI,FNN were exponential curve,the WFTL,MSI of every day were binomial curve,that the CBI was two peak curve and showed significant difference exist between sowing periods,not among varieties,the increase of lately sowed(May,25th)was greater than that of early sowed(April, 8th).Based on the resuits obtained,the science mangement of high quality and high yielding cultivation was can be established. |
