摘要
以"阿波罗"为试材,研究了芦笋幼苗茎数、平均茎粗、平均茎高等地上部生长指标与定植后生长量的关系。结果表明:具有5～7支茎,平均茎粗0.14～0.17 cm,平均茎高30～45 cm的芦笋幼苗定植后生长量最大,可作为芦笋壮苗指标。通径分析表明,定植时幼苗的茎粗对定植后幼苗生长量直接作用最大,其次为茎数。茎数和茎粗可作为芦笋壮苗的优先选择指标。
＂Applo＂ was used to study the correlation of stem number, .average stem diameter and average stem height of asparagus seedlings to the growth index after transplanting. The results showed that the seedlings with 5-7 stems, 0. 14-0. 17 cm average stem diameter and 30-45 cm average stem height had the highest growth index after transplanting. Path analysis showed that the growth index of asparagus seedlings after transplanting was affected mostly by average stem diameter of seedlings and then the stem number which could be taken as main characteristics for vigorous asparagus seedling.
