摘要
在高产生态栽培条件下,通过对天峰薯1号和对照品种金山57主要生理特性的对比研究,探讨了其高产机理。结果表明:天峰薯1号比对照品种金山57早生快发,在各生育期维持较高的光合生产能力;库容量大,块根接纳同化物质能力强,经济系数高,形成了高产的生理基础。该品种具备优质高产、适应性广泛、抗病性强、易于栽培等特性,有一定的推广应用价值。
The high-yielding mechanism of sweet potato variety Tianfeng No .1 was explored through comparative researches on the main physiological characteristics between this variety and the control variety Jinshan 57 under high-yielding ecological culti-vation conditions .The results indicated that Tianfeng No .1 grew faster than Jinshan 57 at the earlier growth stage , and maintained higher efficiency of photosynthetic production in the whole growth and developmental period ;Tianfeng No.1 had large sink capacity, strong ability to accumulate assimilation matter in its tuberous roots , and high economic coefficient;these were the physiological basis that Tianfeng No.1 formed high yield.This variety is characterized by high quality , high yield, wide adaptability, strong dis-ease resistance , easy cultivation , etc., and it has a certain extension and application value .
