对影响马铃薯的几个主要因素及相互作用进行研究,结果表明,当播种密度一定时,种薯大小无一例外地显著影响产量,即种薯越大产量越高,而其他因素包括品种、来源、季节和海拔不同程度地影响生长和产量。播种时,单位面积的种薯出芽数调整为相同时,种薯大小对单位面积产量不产生影响。证明了种薯单位面积产生的主茎数对产量起决定性作用,特别是单株结薯较少的品种和秋冬作。 The main factors influencing potato and their interactions were studied. The results showed that when the sowing density was constant, the seed size significantly affected the yield, that is, the higher the yield, the higher the yield, while the other factors including the variety, source , Season and altitude affect growth and yield to varying degrees. When sowing, the number of sprouts per unit area was adjusted to be the same, and the seed size did not affect the yield per unit area. It proved that the main stalks produced per unit area of ​​seed tubers played a decisive role in the yield, especially the varieties with less tubers per plant and autumn and winter crop.
