栽培深度对百合子球繁育的影响

目的]为百合的种球生产提供指导。方法]以2个东方百合品种和2个亚洲百合品种为材料,设栽植深度51、01、5 cm,研究栽植深度对百合子球繁育的影响。结果]栽植深度对亚洲百合直径膨大倍数和重量膨大倍数的影响差异不显著,对2个东方百合品种子球膨大的影响差异较大。东方百合分生小子球的能力一般都比较弱,亚洲百合仅"白天使"分生子球的能力比较弱,但子球系数均随栽植深度的增加而增加。栽植深度对百合子球地上部分生长的影响比较大,5 cm栽植深度的子球的地上部分起始时间显著高于其他栽植深度,但后期高度基本一致。结论]10 cm的栽植深度比较适宜于东方百合。相对较深的栽培深度,可以大大提高百合子球的生成率。

Effect of Planting Depth on the Breeding of Lily Bulblet

Objective] The purpose of the study was to supply guidance for the production of lily bulblet.Method] With 2 Oriental lily varieties and 2 Asiatic lily varieties as materials,the planting depths of 5,10 and 15 cm were set up to study the influence of planting depth on the breeding of lily bulblet.Result] The influence of planting depth on the enlargement multiples of diameter and weight of Asiatic lily had no significant difference and that on the bulblet enlargements of 2 Oriental lily varieties had bigger difference.The bulblet meristic ability of Oriental lily was weaker generally and only that of Baitianshi in Asiatic lily was weaker,but the bulblet rate increased along with the increment of planting depth.The influence of planting depth on the growth of the aerial part of lily bulblet was bigger and the initial time of the aerial part of bulblets planted at the depth of 5 cm was significantly higher than that at the other planting depths,but the late heights were basically accordant.Conclusion] The planting depth of 10 cm was more suitable for Oriental lily.The relatively deeper planting depth could enhance the generation rate of lily bulblet greatly.
