马铃薯化肥减量增效试验

为实现化肥减量增效目标，特以马铃薯为试材进行了该试验。结果表明:在马铃薯肥效试验过程中，在同施商品有机肥的基础上逐渐减少化肥用量10%~30%，马铃薯产量和效益保持相对稳定，达到了减量增效的目的。

Experiment on Chemical Fertilizer Reduction and Efficiency Increasing in Potato

To achieve the goal of chemical fertilizer reduction and efficiency increasing, the potato was used as material in this experiment. The results showed that the chemical fertilizer was gradually reduced by 10%~30% while commercial organic fertilizer was applied, the yield and benefit of potato remained relatively stable, the goal of chemical fertilizer reduction and efficiency increasing was realized. ;
