查询词典 hydrogen

Both CaCN2 and urea inhibited the chlamydospore germination, mycelial growth and sporulation of the pathogen, but CaCN2 by using at the rates of 0.5 and 1.0%, had two inhibition zones for chlamydospore germination with time while urea had only one. Calcium cyanamide was also more effective on reducing mycelial growth and sporulation of the pathogen than urea did. Therefore, the suppression of pea wilt might be due to fungicidal effect of the intermediate products including hydrogen cyanamide and urea from calcium cyanamide.

由氰氮化钙（0.5及1.0%处理者）之抑制曲线在不同的时间出现两个抑制区，而尿素则仅有一个，及氰氮化钙对萎凋病菌菌丝生长及产胞的影响远较尿素为甚，显示氰氮化钙之所以能有效抑制萎凋病的主要因子，或许是来自其中间产物，包括尿素及氟酸的杀菌作用。
