维生素B1对金边黄杨水培诱导的影响
摘要:水培(Hydroponics)是一种新型的植物无土栽培方式,又名营养液培,其核心是将植物根茎固定于定植篮内并使根系自然垂入植物营养液中,这种营养液能代替自然土壤向植物体提供水分、养分、氧气、温度等生长因子,使植物能够正常生长并完成其整个生命周期。这种体现先进生产力的植物栽培技术具有集约化、规模化和精确化的生产优势,而采用这种无土栽培技术培育出来的水培植物(Hydroponics flower)更是以其清洁卫生、格调高雅、观赏性强、环保无污染等优点而得到了国内外花卉消费者的青睐。为了提高水培观赏植物的成活率和观赏价值,以金边黄杨为材料,进行不同浓度的维生素B1溶液对水培金边黄杨的影响研究。结果表明:随着维生素B1溶液浓度的增高,水培金边黄杨的新生叶数和新生根数出现依次增多的变化规律。

Abstract: Hydroponics is a new way of soilless culture of plants, also known as nutrient solution culture, the core is fixed on the colonization of plant roots and to root natural hanging basket into the plant nutrient solution, this can replace the nutrient solution natural soil to plant to provide water, nutrients, oxygen, temperature and other growth factors, so that plants can grow normally plete its entire life cycle. This reflects the advanced productivity technology is intensive cultivation of plants, scale and precision of the production advantages, the adoption
