摘　　要：:试验结果表明 ,在农作物上应用机械深施化肥技术 ,以肥料全部底施 ,深度为 2 0cm ,增产效果最明显。大田示范结果表明 ,小麦增产率为 8.3%～ 10 .5% ,玉米增产率为 7.4 %～ 11.7% ,谷子增产率为 8.9%～ 12 .8% ,其他作物增产率为 8.1%～ 11.5%。同时还具有省工省时、节支增效、减少污染等特点。Test results showed that the most distinct yield increase effect could be got from applying the technique of mechanical fertilization to crop, placing all the fertilizer required into the soil at one time and with the optimum depth of 20cm. The field crop demonstration showed there was an increasing yield rate of 8.3%～10.5% for wheat, 7.4%～11.7% for corn, and 8.9%～12.8% for millet, and the increasing rate of output of other crops was 8.1%～11.5%. At the same time, this technique had some advantages such as saving labor, saving time, saving cost, improving efficiency and decreasing pollution.
