一忌与碳铵混用。尿素施入土壤后,要转化成氨才能被作物吸收,其转化速度在碱性条件下比在酸性条件下慢得多。碳铵施入土壤后呈碱性反应,pH值为8.2～8.4。农田混施碳铵和尿素,会使尿素转化成氨的速度大一忌与碳铵混用。尿素施入土壤后,要转化成氨才能被作物吸收,其转化速度在碱性条件下比在酸性条件下慢得多。碳铵施入土壤后呈碱性反应,pH值为8.2～8.4。农田混施碳铵和尿素,会使尿素转化成氨的速度大
Avoid bogey with ammonium bicarbonate. After urea is applied to the soil, it is converted to ammonia to be absorbed by the crop, and its conversion rate is much slower under alkaline conditions than under acidic conditions. After ammonium bicarbonate into the soil alkaline reaction, pH value of 8.2 to 8.4. Farmland mixed with ammonium bicarbonate and urea, urea will be converted into ammonia at a bogey and ammonium bicarbonate mix. After urea is applied to the soil, it is converted to ammonia to be absorbed by the crop, and its conversion rate is much slower under alkaline conditions than under acidic conditions. After ammonium bicarbonate into the soil alkaline reaction, pH value of 8.2 to 8.4. Farmland mixed with ammonium bicarbonate and urea, will make urea into ammonia at a large rate
