摘要
本文介绍一种新的橡胶芽接法——籽苗芽接法,即采用2周龄左右的籽苗作砧木,将其拔起用绿色芽片芽接。这种芽接技术的要点是:(1)用于芽接的籽苗砧木应处于伸长后期至展叶期阶段;(2)芽片宜采用鳞片芽和叶柄脱落的叶芽;(3)芽接后籽苗生长的最初阶段应适当遮荫;(4)切砧时必须在砧木残茎上保留2片复叶。籽苗芽接的成活率可达70％以上。在海南岛,秋季播种和芽接,至翌年4—5月芽接苗生长2～3逢叶时,即可出圃定植,比培育芽接桩苗约缩短1年时间。
The present paper describes a new method of rubber budding——mini-seedling budding. In this process, 2-week-old secdlings are used as stocks, which are pulled up from the germinating bed before being grafted with green bud-patches. The essentials of this new technique include: (1)The germinated seedling to be used usa root stock should be at such a stage that the leaves are just beginning to nnfold; (2) The bud to be used for budding should be a scale bud or a infrapetiolar bud without petiole, (3) Adequate shade should be provided at the early stage of seedling growth after budding; (4) Two compound leaves should be retained on the snag on cutting back. Budding success of more than 70% has been attained and young buddings grow vigorously. Sowing and budding in autumn give better results in Hainan Island. When 2-3 horls of leaves appear in the following April or May, the young budding can be transplanted to the field. The time needed for such a young budding is about one year less than that for a stumped budding.
