氮、磷、钾等各种化肥都可以通过深施来增加作物对肥料的吸收量,降低肥料的损失,达到增产节肥的目的。一般认为将化肥施于地表以下6~10厘米为深施。当施肥深度达到6~10厘米时,化肥氮的挥发损失显著降低,且基本上符合农作物的农艺要求。
Nitrogen, phosphorus, potassium and other fertilizers can be applied by increasing the amount of fertilizer on crops to reduce the loss of fertilizer to achieve the purpose of increasing production and saving fertilizer. Generally believed that fertilizer applied to the surface of the following 6 to 10 cm for the facilities. When the fertilization depth reached 6 to 10 cm, the volatilization loss of nitrogen fertilizer significantly reduced, and basically meet the agronomic requirements of crops.
