银杏育苗技术试验研究

Studies on Techniques for Growing Seedling of Ginkgo biloba

为探讨银杏壮苗培育技术，于1996年进行了银杏育苗试验研究，结果表明：选择有胚率高的大粒种子进行播种，易发芽出苗，且苗木粗壮；育苗时宜选择排水好的圃地进行育苗，苗床宜高，沟深应在25cm以上；播种后即用地膜覆盖，能提高出苗率，提早出苗，提高生长量；夏季高温时，用塑料遮阳纱遮阳，可防止苗木曝晒，提高苗木保存率，促进苗木生长。

Experiment on growing seedlings of Ginkgo biloba was made in order to inquire into its cultivation teChniques. The results were as follow: The large seeds with embryo were easy to germinate and grow strong seedlings. Seeds should be sowed in the seed plots which had drainage ability. Seed bed should have considerable heighth and its ditch Should be more than 25cm deep. Mulching could enhance rate of emergence, advance emergence stage and improve increment. In high - temperature season, sunshading with plastic screen could prevent solarization of the seedlings, enhance retention rate and promote its growth.
