菠萝系多年生草本作物,一般从植株的生长发育周期来看,用吸芽作种苗定植的约需要18～20个月才能收获;用顶芽、托芽作种苗定植的则需24～30个月才能收获。几年来,我们经过多次试验和大面积生产实践采用精选大苗,下足基肥,勤施追肥,控制开花,封顶喷果的办法,可做到吸芽苗春种冬收;当年种当年收;夏种春收,第二年四月收。顶芽,托芽苗春种夏收,第二年七月收;夏种冬收,第二年十一月至十二月收。比一般栽培的收获期提早半年至一年,大大地缩短了营养期的生长,为菠萝速成栽培闯出了一条路子。 Pineapple perennial herbaceous crops, generally from the plant growth and development cycle point of view, with suction bud seedlings planted about 18 to 20 months to harvest; with top buds, nursery stock for seedlings need 24-30 Months to harvest. Over the past few years, after many tests and large-scale production practices, we have adopted the method of selecting large seedlings, basal footbed, ground dressing, controlling flowering, and topping the fruit. ; Summer kind of spring income, the second year in April received. Top buds, nursery spring seed summer collection, the second year in July received; summer seed collection, the second year from November to December received. Six months to one year earlier than the general harvesting period, the growth of vegetative period was greatly shortened and a shortcut for pineapple cultivation was established.
