马铃薯原种冬季扩繁不同密度栽培试验

Cultivation trial of foundation potato seed propagation in winter with different densities

摘要: 在温室大棚进行马铃薯新品种微型薯闽薯1号冬季扩繁不同密度栽培试验,结果表明:每667 m²播种密度为6000株时,大薯产量最高;密度为4000株时,小薯产量最高;密度为7000株时,种薯产量最高;密度为5000株时,经济效益最高。

Abstract: Potato propagation test with different planting densities in greenhouse for a new tiny-tuber variety “Minshu 1” was conducted in winter. The results showed that the planting density for the highest yield of big potato, small potato and foundation seed potato was 6000, 4000 and 7000 individuals per 667 m², respectively. And the economical efficiency peaked at 5000 plants per 667 m².
