| 摘 要： | 为探讨能源型甘薯新品种"泰中9号"的生长动态,采用两品种随机区组田间试验方法,对试验品种和对照各个栽培生长时期茎叶、薯块、薯干、干率等17项指标进行了分析研究,结果显示,不同甘薯品种T/R为1的时间不同,早熟品种T/R值达到1的时间较早,T/R值接近1.5的时间较短,稳定在1左右的时间较长,后期收获时T/R值大于0.5,说明后期迟衰,以保证高产稳产。甘薯生长后期T/R值相对较大,平稳下降,光和面积较大,有利于甘薯干物率的提高,薯干产量和相对较高。甘薯新品种在进行多年种植时,留种过程尽量使用菜苗圃,建立留种田,避免人工强制选择,薯蔓越来越长,延长甘薯新品种的使用年限。

| Abstract: | To explore new sweetpotato variety of bioenergy-type ＇Taizhong 9＇ growth dynamics,with two varieties randomized block field experiment on the test species and control the growth of each culture period of stems and leaves,tubers,dry chip,dry chip percentage 17 indicators were analyzed,the results showed that sweet potato varieties with different T/R 1 at different times,early maturing varieties of T/R value was the time to reach an early,T/R value close to 1.5 was shorter,stable at 1 or so long,post-harvest T/R values greater than 0.5,indicating that the late decline late in order to ensure high yield.Growth of sweet late T/R was relatively large,steady decline,light and larger,was conducive to the improvement of sweet potato dry matter,dry matter yield and relatively high.During the years new varieties of sweet potato cultivation,the remaining species of the process to make use of vegetable nurseries,the establishment of farm stay,to avoid artificially forced choice,potato vine longer and longer,extending the useful life of new varieties of sweet potato. |
