Abstract: |
|||
| This invention relates to a nitrogen-fixing agent with high-efficiency multielements, which can increase utilization ratio of nitrogen fertilizer and prevent if from lumping. It can be applied independently or together with nitrogen fertilizer; and free from effects of surrounding. This agent is prepared from zeolite, magnesium powder, Chinese medicien stone, bentonite, sepiolite, via crushing, screen classification, to get 100-500 mesh powder. It is mixed with nitrogen fertilizer in the proportion of one third, and is laid aside in open-air, under adverse circumstance of high-temp. and high humidity for 255.22 hrs.. When the amount of fixed nitrogen is tested, it increases by 1.53-2.2 times. The production cost is reduced by 2 times than that of ammonium bicarbonate. It can increase the harvest over 1-3 tenth. | |||
