The results show ed that: CO2 enrichment for3 h every morning or 6 h every day at 1100± 100L /L m ade the content of m ost mineral nutrients in differentorgans of cucum ber seedling decreased; Prolonging CO2enrich ment tim e led to the m uch low er content. How ever,as a result of CO2 enrichm ent, th e absorption ability of cucumber seedling w as strengthened and the total amountsof mineral nutrients absorbed increased, the m ore the enrichm ent tim e, the more the absorption amounts w ere. Itis suggested that m ore mineral nutrients should be applied when CO2 enrichment is carried.Key words: CO2 enrichm ent; cucumber; mineral element102 j&lt;ýñÐ2005 M</p>
