摘    要:对不同提取方法获得的海藻提取物在黄瓜叶面上进行喷施效果试验,测定土壤绝对含水量,抗旱系数,叶片相对含水量,叶片自由水、束缚水含量,相对电导率,脯氨酸含量等指标,采用隶属值法进行数据分析,结果表明在9种海藻提取物中,A2(20%海藻提取液)和A7(50%海藻提取液)组增强作物抗旱性最强,具有作为开发研究的可能性。

关 键 词:海藻提取物  抗旱  效果

Abstract:Seaweed extracts obtained by different extracting methods were sprayed to leaves of cucumber and measured the coefficient of anti-drought,the relative water content of leaves,the free water content of leaves,the astricted water content of leaves,the relative conductance,the content of proline and the abosolute water content of the soil.The data obtained were analyzed by maths function method.The results show that the most strong seaweed extracts with the ability of anti-drought are A_2and A_7 among 10 samples.The seaweed extracts with the ability of anti-drought can be considered to be main ingredients of seaweed plant promoter.
Keywords:Seaweed extracts  anti-drought  effect
