化肥深施,能够防止肥分挥发损失,是提高肥效,增加产量,降低农业生产成本的有效措施。因为深施,化肥被土复盖,与空气直接接触面减少,可防止氮素的挥发损失。据测定,碳氨表施一日后损失83%,深施只损失33.9%。尿素深施,可减少因尿素酶作用向碳氨转 Deep fertilizer, fertilizer can prevent volatile loss, is to improve fertilizer efficiency, increase production, reduce agricultural production costs and effective measures. Because of deep application, fertilizers are covered by soil, reduce the direct contact with the air, to prevent the loss of nitrogen volatilization. It has been determined that the carbon monoxide lost 83% on one day and only 33.9% on the other. Deep urea, can reduce the role of urease to carbon ammonia turn
