在南非进行了一个历时6年的菠萝修剪试验,研究在收获后不久剪除所有着果吸芽的效果。结果表明,剪除吸芽的在四年内部能增产,以后产量下降,最后二年的减产是由于菠萝植株的正常退化和线虫侵害所致。然而,未剪除吸芽的植株产量不断下降,果实数量和重量也比剪除吸芽的小得多。 A six-year pineapple pruning trial was conducted in South Africa to study the effect of pruning all fruit buds shortly after harvest. The results showed that the cuttings were able to increase the yield within four years and the subsequent decline. The decrease in the last two years was due to the normal degeneration of pineapple plants and nematode infestation. However, the yield of non-primed shoots is declining, and the number and weight of the fruits are much smaller than the pruning buds.
