茶树短穗扦插是目前繁育良种和解决种苗的一项有效方法。但现行的育苗技术,发根慢,成苗时间长,管理亦较费工。如何促进提早发根,快速成苗,提高工效,则是今后必须进一步研究的问题。 五十年代初期,曾有人研究不同光度对作物发育的影响,并在甘蔗、水稻、蔬菜等大田作物上取得了成效。为了探索光度对扦插发根的影响,我们于1980年开始采用不同色泽的塑料薄膜遮阴观察茶树短穗扦插的发育状态,并于1983年作比较试验,其结果如后。
Short cuttings of tea tree is an effective way to breed good seeds and solve seedlings. However, the current nursery techniques, hair root slow, a long time seedlings, management is also more labor. How to promote early rooting, rapid seedling, improve work efficiency, it is the issue that must be further studied in the future. In the early 1950s, people had studied the effects of different luminosity on crop development and achieved successes in field crops such as sugar cane, rice and vegetables. In order to explore the impact of photometric on rooting of cuttings, we began to observe the development of short-cuttage cuttings of tea tree by using shades of plastic film with different color in 1980. The results were compared in 1983.
