摘要
为云南菠萝优质高产种植提供技术依据,采用田间试验研究不同颜色遮阳网(黑色、绿色和蓝色)与覆盖时间(菠萝谢花后60d、45d、30d覆盖)对菠萝日灼率、产量和品质的影响。结果表明:绿色和蓝色遮阳网防日灼效果优于黑网,尤其以蓝色遮阳网效果最佳;覆盖时间对菠萝外观性状及品质影响明显,谢花后60d覆盖蓝色遮阳网菠萝果实的纵、横径大,果眼数适中,果形指数适宜,果实硬度较大,Vc含量高,总酸度低,可溶性糖含量高,外观及品质综合性状好,产量较高。谢花后60d覆盖蓝色遮阳网可实现菠萝的优质高产种植。
For the sake of providing the technical basis for cultivation of pineapple with good quality and high yield in Yunnan,a field experiment was conducted to explore the effects of different color(black,green and blue)and covering time(covering after 60 d,45 dand 30 dof pineapple flower fading)of sunshade net on sunscald rate,yield and quality of pineapple.Results:The prevention to sunscald effect of blue sunshade net performed the best,followed by green and black sunshade net.The covering time had obvious effects on appearance characters and quality of pineapple.The pineapple covering with blue sunshade net after 60 dof flower fading was featured with large longitudinal and transverse diameter,medium fruitlet number,suitable shape index,high fruit hardness,high Vc content,low total acid,high soluble sugar content,good comprehensive traits of appearance and quality and high yield.The pineapple covering with blue sunshade net after 60 dof flower fading could gain high yield and good quality.
