查询词典 damping

Field experiment showed that coating agent with uniconazole (No2 uniconazole seed-coating agent) could significantly defend cucumber seedlings agaist damping-off, inhibit vertical growth and strengthen in thickness of young seedlings. It could blossom early, significantly increase fruit numbers per plant and yields of early stage and total yield. After coating cauliflower seeds by No2 uniconazole seed-coating agent, the uniconazole coating did not affect emergence rate, reduced damping-off disease incidence, increased stem diameter and fresh weight of seedling underground parts.
