摘要
为了探讨试管苗不同种植密度对马铃薯微型薯的影响,本试验设计了3个种植密度,即每平方米130株、225株及400株。结果表明:随种植密度的增加,总块茎数和总产量逐渐上升。每平方米400株是3种密度中的最佳栽培密度,获得块茎数多,产量最高,且中大薯、中小薯和小薯块茎数分别达到每平方米178个、475个及394个。
Three plant densities viz.130,225,and 400 plantlets in vitro transplanted per square meter were designed to investigate the tuberization of potato minitubers.The results showed that the number of tubers and total production were increased as the increase of density.More numbers of tubers and higher yield could be gained from 400 plantlets in vitro transplanted per square meter and the number of large-medium tubers,medium-small tubers and small tubers were 178,475,and 394 per square meter,respectively.
