密度及施钾量对脱毒马铃薯费乌瑞它产量的影响

Effects of Different Planting Density and Potassium Level on Yield of Feiwuruita(a Virus-free Potato Variety)

采用2因素3水平随机区组试验设计,在贵州省余庆县600 m海拔水稻与马铃薯轮作区进行了脱毒马铃薯费乌瑞它最佳播种密度、施钾量试验研究。结果表明,密度、施钾量、密度×施钾量有显著差异。密度为5 000窝/667m2需配施钾15 kg/667m2、4 500窝/667m2需配施钾10 kg/667m25、000窝/667m2需配施钾15 kg/667m2的水平才能达到较高产量。

Feiwuruita （a virus-free potato variety） was tested by the randomized blocks design to study effects of different planting density and potassium level on its yield in Yuqing county with 600 meters above sea level. The results showed that there were significant difference between densities, potassium levels and density × potassium level and the highest yield （1722.2 kg/667m^2） could be obtained under 5 000 plants/667m^2 and 15 kg/667m^2 of potassium level.
