2个白术品种区域试验初报

为确定良种推广范围，白术Atractylodes macrocephala浙术1号、浙术2号2个品种在浙江省南、北、中新老主产区的文成、新昌、嵊州、临安和安吉等5个县（市）设点进行区域试验。结果表明，植株存活率、根茎产量和根茎优形率3项主要指标，品种和品种与地点互作效应达到极显著或显著水平，其中浙术1号显著优于文成、安吉、临安和嵊州的对照，可以在上述各县与试点相似的地方试推广；浙术2号生长表现一般或不良，需继续试验研究后再定。表4参3

A regional experiment of 'Zheshu No.1' and 'Zheshu No.2' cultivars of Atractylodes macrocephala in Zhejiang Province

The rhizome of Atractylodes macrocephala is famous medicinal material. ‘Zheshu No. 1＇ and ‘Zheshu No. 2＇ are new cuhivars chosen by the Zhejiang Forestry College and the Traditional Chinese Medicine Institute of Pan＇ an County. A regional experiment in southern, northern, and central Zhejiang Province on ‘Zheshu No. 1＇ and ‘Zheshu No. 2＇ cuhivars of Atractylodes macrocephala was carried out in both new and old rhizome producing areas of Wenchen, Xinchang, and Anji Counties as well as Shengzhou and Lin＇ an Cities. Every field area of 12.5 m^2 were planted 200 plants in March with three replication for one cuhivar in one county or city. The local cultivars were as the control. Analysis of variance with main plots as cultivars and sub plots as sites was used to analyze three important features ： survival rate, rhizome production, and rate of superior formed rhizome. Interaction between cuhivars as well as between cuhivars and sites were all significant （P 〈 0. 01 ）. ‘Zheshu No. 1 ＇ could be introduced to these cities and counties for popularization experiments, whereas the properties of ＇Zheshu No. 2＇ were poor.
