摘要
以菠萝品种粤引澳卡为材料、露地栽培为对照,研究了地膜覆盖栽培对菠萝植株抽蕾、果实成熟期以及果实成熟时菠萝植株生物量、果实品质和种植成本等的影响。结果表明,地膜覆盖栽培有利于促进菠萝植株提早抽蕾和成熟,提高了植株高度、株重、叶长、叶宽、青叶数、青叶重和根重等生物量指标,提高了菠萝果实单果重、纵径、横径和果眼数等外观指标,提高了果实可溶性固形物、还原糖、蔗糖、全糖的含量及糖酸比等品质指标,降低了可滴定酸和Vc含量。地膜覆盖栽培菠萝虽增加了地膜的成本,但大大减少了果园的除草次数和除草用工,因此在较大程度上降低了菠萝的生产成本。
In this trial,the pineapple cultivar ＇Yueyinaoka＇ was used as materials to determine the effects of film mulching on flower-bud initiation,fruit maturity period,plant biomass,fruit quality and production cost,with open field as control.The results indicated that the plants of film mulching treatment were flower-bud initiating earlier than control.And the fruits of treatment were also matured earlier.Film mulching increased some biomass indexes such as height and weight of plants,length and width of leaves,amount and weight of green leaves,and weight of roots.Film mulching increased the indexes such as weight of individual fruit,vertical and transverse diameter of fruits,and amount of eye-fruits.Film mulching increased the quality indexes such as total soluble solid content,content of reverse sugar,content of sucrose,content of total sugar,and ratio of sugar/acidity.And also,film mulching decreased the content of acidity and vitamin C.In spite of the cost of film,but it decreased the frequency and man-days of weeding.So film mulching decreased the production cost of pineapple fruits in some degree.
