摘要
以越橘北陆为试材,进行多年生主枝修剪试验,分别于2009年和2011年对单株产量、果实品质和树体枝条生长进行调查分析。结果表明,(1)越橘单株坐果数和产量随着多年生主枝留枝量的增加而增加,并呈现逐年增加的趋势;(2)修剪后果实品质较对照有所提高,以T5处理即单株留4条主枝果实可溶性固形物含量最高;(3)多年生主枝的修剪对北陆树体更新复壮起到促进作用,留1~5条主枝树体更新复壮效果依次降低,但6个处理均优于对照(不修剪)。
The yield of per plant, fruit quality and shoot characters of blueberry cultivar Northland were investigated in 2009 and 2011 respectively after the pruning of perennial main canes. The results were as fol- lows. ( 1 ) The amounts mount of perennial main treatment with four main of blueberry fruit set and yield increased canes. (2) Pruning canes reserved. (3) regenerate of blueberry Northland. The effects from 1 to 5. gradually with the raising of remaining a- improved the fruit quality, and the soluble solid content of the Pruning perennial main canes played a promotive role in plant of pruning decreased with the increase of reserved main canes
