【摘要】 将不同品种3年生芦笋宿根和5年生芦笋宿根移栽至日光温室,定期采收芦笋嫩茎,比较其秋冬茬生物产量、经济产量和经济系数。结果表明:不同生长年限的芦笋宿根对鲜笋产量影响不同,除个别品种外,3年生芦笋的生物产量、经济产量及经济系数普遍高于5年生。这种差异可能与试验前芦笋宿根原生长地土壤肥力有关。更多还原

【Abstract】 Three-year and five-year perennial roots of Asparagus officinalis L.(perennial roots) were respectively transplanted to greenhouse,and the young shoots of them were harvested periodically to compare biological yield,economic yield and economic coefficient(three characteristics) between them at autumn-winter batch.The results indicated that the perennial roots with different growing years had different influences on yield of fresh bamboo-shoot;except a few varieties,the three characteristics of three-year perennial root were generally higher than that of five-year perennial root,and this difference may relate to the soil fertility of original field where the experimental perennial root grew before transplant.更多还原
