【摘要】 实验研究了氨水、碳酸铵和尿素对秸秆的促腐效果,结果表明:3种溶液中,氨水的促腐效果最好,施用浓度为4%的氨水,12h后对粗纤维的降解率可以达到20.6%.田间实验表明:喷洒浓度为6%氨水的玉米秸秆半年后,粗纤维的最大降解率可以达到48.2%,降解情况明显高于没有喷洒的秸秆.这种促腐既减小了对小麦出苗的不利影响,又增加了土壤肥力.更多还原

【Abstract】 Effects of ammonia,urea and ammonium carbonate on corrosion of corn stalk were investigated via experiments.Results showed that the ammonia is the best among them.Degradation degree of coarse fibre treated with 4% ammonia reached 20.6% after 12 hours.Experiments in farm showed that degradation degree of coarse fibre reached 48.2% half a year after treated with 6% ammonia,much higher than those without any treat ment.This accelerated corrosion of corn stalk not only reduces its adverse effect on seedling of wheat,but also increases soil fertility.更多还原
