甘薯新品种龙津薯1号不同茎蔓节段栽培效果研究

    Planting performances of different vine sections of new sweet potato variety “Longjinshu No.1”

    • 摘要: 为研究龙津薯1号不同茎蔓节段的栽培效果,对一、二、三、四、五等5个苗段分别测定种植效果,结果表明:一苗段(茎尖30 cm)产量最高,每667 m2产量2770.0 kg,极显著高于其他苗段;苗段越往基部产量越低,但二、三、四苗段间差异不显著,与第五苗段对比增产均达极显著水平。因此生产上应尽量使用一苗段,适当使用二、三、四苗段,淘汰五苗段;影响产量的主要因素是结薯时间、单株结薯数,以及薯块大、中、小比例。

       

      Abstract: The vine of "Longjinshu No.1" were divided into 5 sections from top to base to study their planting performances. The results showed that Section 1 received the highest yield, 2770.0 kg per 667 m2, which was very significant than those of others. The lower yield was observed following with the section was closer to the base of the vine. The yield of Section 2, Section 3 and Section 4 were with no significant differences, but extremely significantly higher than that of Section 5. Therefore, in the productive practice, Section 1 of the vine was best for planting, and Section2, 3, 4 could be suitably used, but Section 5 need to be obsoleted. The main factors affecting on yield included tuberization time, tuber amount per plant, and the ratio of big, middle, and small tubers.
