对石竹出笋退笋规律的研究表明 ,石竹出笋时间始于 5月 1日左右 ,历时约 36d ,出笋初期出笋少 (持续时间 12d左右 ,占 11 1% ) ,盛期出笋数较多 (持续时间 18d ,占 83 9% ) ,末期出笋数迅速下降 (持续时间 6d ,出笋占 5 0 % ) ,初期出土石竹笋退笋少 ,以后退笋率不断增加 ,但末期退笋率又有所下降。随着笋期的推移 ,退笋高度不断增加 ,退笋生长时间缩短。 The research on the law of withdrawing Shoots from Shoots Shoots showed that Dianthus Shoots Shoots started around May 1, which lasted for about 36 days. Shoot shoots were less in the early shoots (about 12 days, accounting for 11 1%), Shoots (Duration of 18d, accounting for 83.9%), the number of emergent shoots decreased rapidly in the last period (duration 6d, shoots accounted for 50%), the number of bamboo shoots unearthed in the initial period was small, Shoot rate has declined. With the period of bamboo shoots, the height of the bamboo shoots is continuously increasing, and the growth time of the bamboo shoots is shortened.
