多年的生产实践证明，施用磷肥和采用整薯播种都可以提高马铃薯产量。本试验选用同等大小的马铃薯品种‘夏波蒂’脱毒二级原种小整薯和切块作为种薯播种，研究在不同施磷条件下马铃薯产量情况。结果发现，高磷整薯的平均单株结薯数显著高于其他处理，50 g以上块茎高磷整薯的产量显著高于其他处理，而低磷整薯的产量则显著低于低磷切块。

Phosphorus fertilizer application and sowing the whole seed potatoes can increase potato yield. The purpose of this research was to study the effects on tuber yield of sowing the whole seed potatoes and seed pieces under different phosphorus levels using the second-grade elite seed potatoes of the variety‘Shepody’as plant materials. The results showed that sowing the whole seed potatoes combined with high phosphorus input significantly increased the tuber number per plant and the yield of tuber larger than 50 g was also significantly higher in the whole seed under high phosphorus input than other treatment combinations. However, under low phosphorus conditions, the yield of sowing the whole seed potatoes was significantly lower than seed pieces .
