徐薯18是我所1976年育成的甘薯新品种.该品种高抗根腐病,适应性广,高产性能突出.几年来试验结果,徐薯18比胜利百号鲜薯平均增产30.6%,薯干平均增产50.8%.据不完全统计,1981年省内外已推广种植1200万亩以上,目前仍处于迅速推广阶段.为探求徐薯18产量形成的生理特点,我们在前人研究的基础上,根据近几年的研究结果,就其干物质的生产、积累、分配和生理代谢特点进行分析,为高产栽培提供理论依据.
Xushu 18 is a new sweet potato variety bred in 1976. The variety is highly resistant to root rot and has wide adaptability and high yielding performance. In recent years, the test results showed that Xushu 18 increased 30.6% An increase of 50.8% .According to incomplete statistics, in 1981 the province has been planted to promote more than 1,200 acres, is still in the rapid promotion stage.In order to explore the physiological characteristics of the production of Xushu 18, on the basis of previous studies, according to the recent Years of research results, analysis of their dry matter production, accumulation, distribution and physiological and metabolic characteristics, provide a theoretical basis for high-yield cultivation.
