‘乌壳雷竹’良种及其栽培技术

An Improved Variety of Phyllostachys violascens‘Wuqiaoleizhu’and Its Cultivation Techniques

‘乌壳雷竹’(Phyllostachys violascens‘Wuqiaoleizhu’)属于竹亚科(Bambusoideae)刚竹属(Phyllostachys)雷竹的变异种,2006年3月发现于湖南省芷江县从浙江引种的雷竹群体中,经多年繁育观测,其性状表现一致、稳定。与雷竹的箨鞘红褐色、具稀疏褐色斑点明显不同,‘乌壳雷竹’箨鞘整体为青褐色或乌褐色,具不均匀、大小不一的黑褐色斑块。‘乌壳雷竹’具有出笋早、笋期长、产量高、笋质优等特点,2021年3月通过湖南省林木良种审定(湘S-SV-PV-001-2021)。文章介绍了‘乌壳雷竹’特性及其栽培技术,以期为其扩大栽培提供参考。

‘Wuqiaoleizhu'is a variety bred from Phyllostachys violascens in the genus of Phyllostachys of Bambusoideae.In March 2006,it was found and identified in the cultivated population of Ph.violascens in Zhijiang county,Hunan province,which had been introduced from Zhejiang province.After years of breeding and character observation,its character performance is found consistent and stable.Unlike Ph.violascens which has the red brown sheath with sparse brown spots on the surface,‘Wuqiaoleizhu'has the green brown sheath or black brown sheath,with black brown patches of uneven and varying sizes.‘Wuqiaoleizhu'has the characteristics of early shoot emergence,long shooting period,high shoot yield,and excellent shoot quality.In March 2021,it achieved the examination and approval of improved varieties in Hunan province(Xiang S-SV-PV-001-2021).This paper introduces the characteristics and cultivation techniques of‘Wuqiaoleizhu'in order to provide references for its expanded cultivation.
