Walnuts in China

摘要

China produces a lot of walnuts. Here is a report on a visit to northern China by the Nursery Manager of Webster Walnuts, the only large-scale commercial producer of quality walnuts in Australia - Webster manages 650 hectares of walnut orchards in Tasmania and 250 hectares in the Riverina, N.S.W. In total, over 300,000 trees. In June 2005 I visited Shanxi province in northern China. Our base was in Taiyuan. The purpose of the visit was to share knowledge on walnut propagation, orchard developments, varietal selection and tree training techniques. The main propagation technique used in Shanxi province is patch budding using selected English walnut rootstock. Success rates appeared to be quite good, however repeat budding on rootstocks due to bud failure was common. Successfully budded trees were lifted by hand using a heavy hoe when the trees were dormant.
