摘要
为进一步研究缓释肥在贵州马铃薯上的施用效果,设置盆栽试验研究缓释肥与有机肥配施对马铃薯产量及养分吸收的影响。结果表明:缓释肥与有机肥配施能满足马铃薯对养分的需求,有机肥与减量20%缓释肥施用仍能达到较好的增产效果,并在一定程度上减少了肥料成本投入与生产劳动成本投入。
A pot experiment was conducted to study the effects of mixed application of slow-release fertilizer and organic manure on yield and nutrient absorption of potato for discussing the application effect of slow-release fertilizer in potato cultivation in Guizhou.The results showed that the mixed application of slow-release fertilizer and organic manure could meet the nutrient requirement of potato growth.The mixed application of organic manure and 80% slow-release fertilizer amount still increased potato yield,which could reduce fertilizer and labor cost.
