播期对脱毒马铃薯费乌瑞它产量的影响

The Effect of Different Sowing Time on Yield of Feiwuruita(a Virus-free Potato Variety)

在对余庆县海拔600m地区稻田不同播期对脱毒马铃薯费乌瑞它生长发育及产量的影响研究结果表明，不同播期显著影响脱毒马铃薯产量，播期间产量差异达极显著水平，以1月18日至2月7日播种产量最高，产量在1409．7～1606．

Feiwuruita, a virus-free potato variety, was tested by using different sowing time to study the effect on its yield. The results showed that different sowing time significantly affected its potato yield and there was very significant difference in potato yield between treatments of different sowing time. The higher potato yield（1409.7 to 1 606.5 kg/667m^2） could be obtained when the sowing time was between 18, January to 7, February.
