鲁南地区历年春播马铃薯 ,同一个品种同时、同法播种在同一块地里 ,就是在同一行中也总是会发现出苗时间参差不齐 ,收获时同行相邻植株间的单株生物产量和经济产量差异都极为显著。为了探索因种薯所处的芽位不同 ,其出苗期、产量的差异等进行本试验。　　试验证明 ,上述差异因 Lunar New Year Lunar New Year in southern Shandong potato, the same species at the same time, the same law sowing in the same line, it is always found in the same row of seedling time is uneven, the same plant at harvest adjacent plants per plant biomass and Economic output differences are extremely significant. In order to explore the seedling where the seed is different, the seedling emergence, yield differences for the test. Test proved that the above differences
