不同留种时期对湿栽水芹花茎性状及后期产量的影响

摘要

Taking a wettish-cultivated water dropwort in Jiangyin as material, we studied the effects of different transplant periods on flower stalk characters, yield and propagation coefficient of the water dropwort. The results showed that, the water dropwort transplanted on April 20th produced thicker flower stalks with denser buds, and had higher yield, but its propagation coefficient was lower. While the water dropwort transplanted in June 20th produced longer and softer flower stalks, and its yield had no significant difference with those transplanted in May 20th.%以江阴湿栽水芹为试材，研究了不同留种时期对花茎性状、后期产量、花茎播种效果的影响。研究结果表明，4月20日留种抽生的花茎较粗、芽位稍密，播种后的水芹产量较高，但繁种系数较小；6月20日留种抽生的花茎节间稍长、花茎较柔软，小区产量及播种后产量与5月20日留种的相近。
