Description

一种金花竹芋花期调控方法
技术领域
本发明涉及一种花卉栽培方法领域;特别是竹芋栽培方法领域。
背景技术
金花竹芋又名金花冬叶、金苞肖竹芋,为竹芋科肖竹芋属多年生草本植物,是竹芋中为数不多的既能观花,又可赏叶的品种。植株丛生,高约30厘米,叶长椭圆形,长12厘米至15厘米,宽7厘米左右,叶缘稍有波浪形起伏,叶面灰绿至深绿色,叶背暗紫红色。花序由叶丛中抽出,通常高出叶面,苞片橘黄色,黄色小花盛开于其内,花期冬、春季节。金花竹芋原产于南美洲的巴西,喜高温高湿的半阴环境,不耐寒,忌烈日暴晒,否则会因光线过强使叶片卷缩、变黄,基至叶面产生焦斑,严重地影响生长和观赏。
目前,我国花卉产业发展迅猛,并且表现出这样一个趋势,即传统花卉价格越来越低,而新品种花卉一般都具有很高的价格优势。不断引入优质的花卉新品种,是提升我市花卉市场的重要途径之一。
金花竹芋花期调整的目标是使其在春节期间开花,以便供应春节市场。随着金花在国内推广的增加,春节市场很快趋于饱和,因此,应进一步研究金花竹芋其他开花时期的调控措施,使其能在一年中的其他季节开放和供应市场,如在五一节或国庆节期间开放和上市,这样可进一步拓展金花竹芋的市场空间,有利于较为长远的发挥该品种的经济效益。
发明内容
针对这种现象,本发明为解决公知技术中存在的技术问题而提供一种金花竹芋花期调控方法,以解决不同时期市场规模化需求。
本发明的另一个目的是人为的控制金花的开花时间与花期时间的长短以及开花时间的基本一致。
本发明为解决公知技术中存在的技术问题所采取的技术方案是:
一种金花竹芋花期调控方法,进行为期90天的人工短日照处理作为促花期,即:每天黑暗期14小时,有光期10小时,连续进行90天;在促花期内温度白天保持在26~28℃,夜间24~25℃,湿度白天75%~85%,夜间90%左右,有光期光照强度保持在18000~20000lux之间;在促花期的第一个月以磷肥0.4g/L,钾肥0.2g/L,以及花多多1号全元素肥料EC=1.5配制成的混合水溶液(在一升水中顺次加入磷肥0.4g、钾肥0.2g、花多多1号全元素肥料EC=1.5)直接浇灌在盆土中,每5~6天浇灌一次,当短日照处理进行90天后,以磷肥0.1g/L,钾肥0.15g/L,以及花多多1号全元素肥料EC=0.5~0.8配制成的混合水溶液(在一升水中顺次加入磷肥0.1g、钾肥0.15g、花多多1号全元素肥料EC=0.5~0.8)直接浇灌在盆土中,每5~6天浇灌一次,另外控制温度在:白天23~25℃,夜间20~22℃,持续45天为止。
本发明具有的优点和积极效果是:克服了原先金花竹芋只在11~12月份开花的难题,可以使金花竹芋在全年任何一个月都开花,并且花期由原来的自然花期30天延长至现在的45天,花箭数量由原来的3~4支,增加到现在的6~8支,另外花期时间基本一致。
具体实施方式
为能进一步了解本发明的发明内容、特点及功效,兹例举以下实施例:
实例一:以1000盆金花竹芋为试验组,分别在1~10月份分10组进行试验,每月一组,每组100盆。
以试验组别1为例,在促花前期第一个月(即1月1日到2月1日),提高磷钾肥的用量,磷肥由原来0.1g/L提高到0.4g/L,钾肥由原来的0.15g/L提高到0.2g/L,同时给予全元素肥料(花多多1号)EC=1.5。以磷肥0.4g/L,钾肥0.2g/L,以及花多多1号全元素肥料EC=1.5配制成的混合水溶液(在一升水中顺次加入磷肥0.4g、钾肥0.2g、花多多1号全元素肥料EC=1.5)直接浇灌在盆土中,每5~6天浇灌一次。
从1月1日开始,每天黑暗期14时,有光期10小时连续进行90天。在促花期内温度白天保持在26~28℃,夜间24~25℃,湿度白天75%~85%,夜间90%左右,光照18000~20000lux之间。
催花处理90天后即可看见花朵出现,此时起(即组别1的100盆金花竹芋4月1日以后)减少全元素肥料(花多多1号)的用量:由原来的营养液EC=1.5,下调至EC=0.5~0.8,以磷肥0.1g/L,钾肥0.15g/L,以及花多多1号全元素肥料EC=0.5~0.8配制成的混合水溶液(在一升水中顺次加入磷肥0.1g、钾肥0.15g、花多多1号全元素肥料EC=0.5~0.8),每5~6天浇灌一次,另外降温温度由原来的白天26~28℃,夜间24~25℃,下调至白天23~25℃,夜间20~22℃。持续45天为止。
不同催花时期,催花效果对比表(每组100盆金花竹芋)

9 9月1日-12月1日 100 100 100% 8 45
10 10月1日-1月1日 100 99 99% 7 44
组别2的100盆金花,在促花前期第一个月(即2月1日到3月1日),提高磷钾肥的用量,磷肥由原来0.1g/L提高到0.4g/L,钾肥由原来的0.15g/L提高到0.2g/L。以磷肥0.4g/L,钾肥0.2g/L,以及花多多1号全元素肥料EC=1.5配制成的混合水溶液(在一升水中顺次加入磷肥0.4g、钾肥0.2g、花多多1号全元素肥料EC=1.5)直接浇灌在盆土中,每5~6天浇灌一次)
从2月1日开始,每天黑暗期14时,有光期10小时连续进行90天。在促花期内温度白天保持在26~28℃,夜间24~25℃,湿度白天75%~85%,夜间90%左右,光照18000~20000lux之间。
催花处理90天后即可看见花朵出现(1~3天内同一组别的100盆花均出花),此时起(即组别2的100盆金花竹芋5月1日以后)减少全元素肥料的用量:由原来的营养液EC=1.5,下调至EC=0.5~0.8,磷肥降低到0.1g/L,钾肥降低到0.15g/L,以磷肥0.1g/L,钾肥0.15g/L,以及花多多1号全元素肥料EC=0.5~0.8配制成的混合水溶液(在一升水中顺次加入磷肥0.1g、钾肥0.15g、花多多1号全元素肥料EC=0.5~0.8每5~6天浇灌一次)。另外降温温度由原来的白天26~28℃,夜间24~25℃,下调至白天23~25℃,夜间20~22℃。
组别3~10同组别1和2的催花处理方法。
此试验的结果表明,每月的试验在90天后都能够开花,花箭数量由原来的3~4支,增加到现在的6~8支,花期与实例二相比由30天延长至现在的45天,另外花期时间基本一致。
实例二:以500盆金花竹芋为对照组
只做例行的正常养护,不进行短日照处理和提高磷钾肥的用量,也不进行温度的调整,在11~12月份先后的开花,花箭数量3~4支,花期20~30天自然老化脱落。
