Abstract:
The growth of soybean（Glycine max(L.) Merr.）seedlings could be decreased with urea applied as base fertilizer soon hydrolyzed with catalysis of soil urease.Urease inhibitor NBPT was known to inhibit urease activity.However，few reports were found how to apply NBPT for decrease the soil urease activity and increase soybean seedling growth.Using pot experiment to study the effects of NBPT on the urea hydrolysis，the seed emergence and seedling growth of soybean.The results showed that NBPT could inhibit efficiently the soil urease activity in the range of 0.1%~2%.The soybean seed emergence rate and seedling growth was increased when NBPT was applied with urea at 1∶100.NBPT applied 2 days earlier than urea showed a higher inhibition activity and a promotion to soybean seed emergence rate and seedling growth.
