(一)用野生植物的枝条作菌种斜面培养的试验为了解决大量培养“920”菌种缺少马铃薯和琼脂的矛盾,我们采用了多种常见的野生植物培养“920”斜面菌种。方法是先把植物的枝条或地下根茎削成斜面,放入试管中(试管底部先放入一小团吸水棉花,以保证树枝维持一定湿度),管口塞上棉花塞,经高压灭菌 (A) Experiment of Incubation of Wild Strain with Strains of Strain In order to solve the problem of lack of potato and agar in a large number of cultured “920” cultivars, we used a variety of common wild plants to cultivate “920” slant species. The method comprises the steps of: first cutting plant branches or underground rhizomes into bevels and placing them in test tubes (a small group of absorbent cotton is placed at the bottom of the test tubes to ensure that the branches maintain a certain humidity), cotton plugs are put on the mouths and autoclaved
