多年来,我们对低干泡桐开展了平茬接干、抹芽接干和目伤接干等人工接干试验,均取得较好的效果。最近几年,又在禹县褚河公社的余王林场、小刘林场、阁街林场三个泡桐试验基地和扶沟县江村公社林场泡桐试验基地上,对栽植1——2年的泡桐幼树,进行了连续两年剪梢接干试验,取得了更为理想的效果,使520亩,约13000多株泡桐幼树主干平均增高80％,接干新梢长度平均320厘米。现将泡桐剪梢接干效果归纳分析如下,供生产上参考(一)泡桐种类对剪梢接干效果的影响 Over the years, we carry out low-dried Paulownia stubble dry, dry buds and pickling and other hand-pick dry test, have achieved good results. In recent years, again in Yu County Chu River commune Yu Wang Lin field, small Liu Linchang, Court street three paulownia test base and Fugou County commune commune forest Paulownia test base, planting 1 - 2 years Paulownia Trees, carried out two consecutive years pick-dry-tip test, and achieved a more satisfactory results, so that 520 acres, about more than 13,000 Paulownia saplings trunk average increase of 80%, then the average length of the new shoot 320 cm. Now Paulownia pick tip dry effect is summarized as follows, for the production of reference (a) Paulownia species on the shoot tip dry effect
