目前,组织培养快速繁殖正在我国广泛开展,降低成本提高经济效益是此项工作能否应用于生产的关健。为此,我们对如何利用自然光进行培养,以及培养基的重复利用问题进行了研究,现简报如下: (一)自然光照培养,利用大窗户的房间做培养室。为使温度稳定,采用双层玻璃,内层用毛玻璃,可使光线弥散,避免太阳直照。培养架放在窗户附近1.5米处,架面有10度角的斜度,面向窗户。在培养架上的光照强度平均在2,000 1×以上, At present, tissue culture rapid propagation is widely carried out in our country, reduce costs and improve economic efficiency is the key to whether this work can be applied to production. To this end, we conducted a study on how to use natural light to cultivate and how to reuse the medium. The briefing is as follows: (1) Cultivation of natural light in a room using large windows. In order to stabilize the temperature, the use of double glass, the inner glass with frosting, the light can be dispersed, to avoid direct sunlight. Shelves placed 1.5 meters near the window, the shelf has a 10 degree angle of the slope, facing the window. The light intensity on the culture rack averages above 2,000 1 ×,
