增加局部空气中负氧离子的含量,一般要用负氧离子发生器。本试验的目的,就是利用这种发生器,产生较高浓度的负氧离子,增加菇房的新鲜空气,借以观察对平菇生长发育的影响。现将两次试验结果分述如下。
Increase the local air negative oxygen ion content, generally use negative oxygen ion generator. The purpose of this experiment is to use this generator to produce a higher concentration of negative oxygen ions to increase the fresh air Gugu room in order to observe the growth and development of Pleurotus ostreatus. Now two test results are as follows.
