不同播种密度对脱毒马铃薯费乌瑞它产量的影响

The Effect of Different Planting Density on Yield of Feiwuruita(a Virus-free Potato Variety)

对脱毒马铃薯费乌瑞它不同播种密度试验研究结果表明，试验所设种植密度间差异呈极显著水平；以播5500株／667m^2产量最高，为2090．0kg／667m^2；最佳密度为5000-6000株／667m^2，群体生长较合理。建议在余庆县大面积生产中推广应用。

Feiwuruita（a virus-free potato variety） was tested to study the effect of different planting density on its yield. The results showed that there was very significant difference between tested treatments and the highest yield（2 090.0 kg/667m^2 was obtained under the planting density of 5 500 plants/667m^2. The planting density of 5 000 - 6 000 plants/667m^2 should be popularized in production of Feiwuruita in Yuqing county.
