摘要
为了在冀北山区推广应用食用萱草,在河北省承德市丰宁满族自治县首次田间种植3个食用萱草品种大花萱草、黄花菜和科萱1号,对其生物学特性、适应性、物候期、生长发育规律、花蕾产量等进行了测定。结果表明:3个食用萱草品种在冀北山区栽植成活率和越冬保存率均很高,适应性良好;4月中旬左右开始发芽、6~7月进入花期、10月初叶子开始枯萎,开花期间花色鲜艳、花期长、景观效果好;2 a生黄花菜、科萱1号、大花萱草的鲜蕾产量分别为35919.90、23343.60和21954.15 kg/hm^(2),按照干重为鲜重的1/7折算,干蕾产量均超过3000 kg/hm^(2)。本研究结果可为食用萱草在冀北山区的推广应用提供科学依据。
In order to popularize the edible Hemerocallis spp.in northern mountainous area of Hebei,Hemerocallis hybrida,H.citrina and Kexuan No.1 were firstly planted in Fengning Man Autonomous County,Chengde,Hebei Province.The biological characteristics,adaptability,phenological period,growth and development rhythm and flower-bud yield were measured.The results showed that the survival rate and overwintering preservation rate of three materials were high and the adaptability was good.The edible Hemerocallis spp.began to sprout around the middle of April,blossomed from June to July with long flowing period,bright colors and good landscape effect,and leaves began to wither.The flower-bud yield of 2-yearold H.citrina,Kexuan No.1 and H.hybrida was 35919.90 kg/hm^(2),23343.60 kg/hm^(2) and 21954.15 kg/hm^(2),respectively.When the dry weight was converted by 1/7 of fresh weight,the dry flower-bud yield were over3000 kg/hm^(2).This study provides the scientific basis for the popularization and application of edible Hemerocallis spp.in northern mountainous area of Hebei.
