机械深施化肥技术在玉米生产上的应用

Application of Fertilizer-Mechanical-deep-ploughing Technigue in Corn-growing

于1997～2002年在玉米田进行机械深施化肥试验、示范推广。结果表明:以肥料全部做底施,深度为20cm,增产效果最明显,大田示范表明增产率为9 7%～12 1%,同时具有省时、省工、节支增效、减少污染等特点。

In 1997～2002 Fertilizer mechanical deep ploughing technigue test in the corn,the result is:fertilizer which is fully put in the deep soil (20 cm in depth) makes the the yield of maize grow rapidly.The example shows the yield increases by 97%～121%. Besides,it avoids pollution,and it is labor\|saving with less time and less money.
