马铃薯是需镁较大的作物之一，施用镁肥有显著的增产效果。试验结果表明，其平均增产率达１４．７％。施用镁肥的增产效果与土壤交换性镁含量及镁肥的施用量有关。施用镁肥平均使单薯增重１６．８％。大薯率提高８．９个百分点。施用钙镁磷肥可使马铃薯增产１５％左右，故用钙镁磷肥替代过磷酸钙来补充土壤镁的不足，实为一种简便而行之有效的方法
Potato is one of the larger crops that need magnesium, and the application of magnesium fertilizer has significant yield increase effect. The test results show that the average rate of increase of 14.7%. The effect of increasing yield of magnesium fertilizer was related to exchangeable magnesium content and magnesium fertilizer application rate. Applying magnesium fertilizer averaged 16.8% of single potato weight gain. Big potato increased by 8.9 percentage points. The use of calcium magnesium phosphate fertilizer can increase the yield of about 15% of the potato, so the use of calcium magnesium phosphate instead of calcium superphosphate to supplement the lack of soil magnesium, in fact, is a simple and effective method
