摘要
对伯克利蓝莓生长的3个关键期即发芽前、初夏、秋季时,施用3种肥料即硫酸铵、磷酸二铵、氮磷钾复合肥,每株按3个不同的施肥总量即25g、50g、100g进行搭配施肥试验,研究对蓝莓植株生长与果实品质的影响。结果表明,以施用NPK复合肥每株50g,分春夏秋3次分施时,蓝莓的株高、冠幅、新梢长度等生长状况,单果重、单株产量,果实的可溶性固形物含量、有机酸含量、Vc含量等品质指标均最佳。
In order to study the effects on blueberry plant growth and fruit quality,three kinds of fertilizers including ammonium sulfate,diammonium phosphate and NPK compound fertilizer were applied in three key periods of Berkeley blueberry growth.The three key periods are before germination,early summer and autumn.Each plant was applied with three different amounts of fertilizer,25g,50g and 100g.The results showed that when applying NPK compound fertilizer 50g per plant and applying 3 times in spring,summer and autumn,the growth status of blueberry such as plant height,crown width,shoot length,fruit weight,yield per plant,and soluble solid content of fruit,Organic acid content,Vc content and other quality indicators are the best.
