不同肥料配合对马铃薯产量的影响

Influence of Different Fertilizer Combination on Yield of Potato

以脱毒马铃薯品种"脱毒米拉"为试材,探索几种肥料的配合施用对马铃薯生长发育及产量的影响。研究结果表明,增施肥料可以显著提高产量并延长生育期,复合肥、氯化钾肥和尿素的增产效应比较大,过磷酸钙和草木灰的肥料效应不明显。

Potato variety＂virus- free Mila＂was chosen as testing material to explore the effects of several kinds of fertilizer application on growth and yield of potato.The research results showed that increasing fertilizer can significantly improve production and extend the growth period than without any fertilizer,compound fertilizer,potassium chloride and urea had bigger potential to increase yield,how ever,the fertilizer effect of plant ash and calcium superphosphate was not obvious.
