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。
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 m^2,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.
