CO_2施肥在温室花卉生产中应用的研究进展

A Review on Effects of CO_2 Enrichment on Greenhouse Flowers

在温室花卉生产中,室内较低浓度的CO2通常是影响花卉产量和品质的一个重要因素。针对此问题,国内外学者曾开展了大量有关人工增施CO2对温室花卉生长发育影响的研究,相关研究结果为科学增施CO2提供了重要的依据。由于国内开展这方面的研究相对较少,因此以往这些研究成果很少被国内温室花卉生产者使用。从CO2施肥方式、时间及浓度,CO2施肥对温室花卉开花、产量和品质的影响等方面,比较详细地概述了过去数十年关于CO2施肥在温室花卉生产中应用的主要研究成果,以期为国内温室花卉生产者科学增施CO2提供一定的参考。

Low concentration CO2 in the greenhouse is a main factor influencing quantity and quality of greenhouse flowers. In response to it, many researchers at home and abroad have carried out a lot of studies investigating effects of CO2 enrichment on growth and development of greenhouse flowers,which provided mueh valuable information for scientific CO2 fertilization during the production of greenhouse flowers. However,most of studies were performed abroad,thus the results of those previous studies were seldom available to many Chinese farmers in plant- ing greenhouse flowers. Here we present a detailed review on the studies concerning CO2 enrichment during production of greenhouse flowers over the past several decades from the application methods, time and concentration of CO2 enrichment,and effects of CO2 enrichment on effects of flowering time, quantity and quality of greenhouse flowers, aiming to provide some useful information for scientific CO2 enrichment in production of greenhouse flowers in China.
