不同有机肥施用量对马铃薯产量的影响

Effect of Different Organic Fertilizer Application Amount on the Yield of Potato

不同有机肥施用量对马铃薯产量的影响试验结果表明,在施等量化肥的基础上,以施有机肥60 t/hm^2的产量最高。因此,建议在合理使用化肥的同时,施用有机肥30-60 t/hm^2,增产效果明显。

The results of effect of different organic fertilizer application amount on potato showed that, on the basis of the equivalent chemical fertilizer,the yield was the highest when organic fertilizer was 60 t/hm^2.It was suggested that at the same time of the rational use of chemical fertilizer, the yield increased obviously when the organic fertilizer was 30-60 t/hm^2.
