以黄瓜品种中农26号为试验材料,研究根施萘乙酸钠对日光温室春茬黄瓜生长、产量及品质的影响.结果表明:与对照相比,根施6 mg·株-1萘乙酸钠显著加快了黄瓜地下部、地上部干物质的积累,黄瓜株高、叶片数、根系活力、叶绿素含量、净光合速率、水分利用率、VC含量、可溶性蛋白含量均显著提高.单株产量、单株果数和总产量也显著提高,分别比对照增加22.37％、32.36％和22.13％.表明在日光温室春茬黄瓜生长中,根施6 mg·株-1萘乙酸钠可以提高黄瓜根系活力、光合速率,促进黄瓜的生长,进而提高产量.%In order to provide theoretical and practical basis of improving greenhouse cucumber yield combined with the water and fertilizer,using different level of sodium naphthalene acetate (SNA) and cucumber cv.‘Zhongnong No.26’ as material.The results are significantly affected by sodium naphthalene acetate treatment.The treatment of 6 mg per plant significantly accelerate the cucumber growth rate,dry matter accumulation,increased number of leaves,chlorophyll contents,net photosynthetic rate (Pn),stomatal conductance (Gs),root activity and fruit VC contents compared with the control.The yield per plant,number of fruit per plant and total yield were significantly increased in plant treated with 6 mg per plant of sodium naphthalene acetate,which increased by 22.37％,32.36％ and 22.13％ compared with the control respectively.From this study it is concluded that the sodium naphthalene acetate treatment of 6 mg per plant can increase the root activity,raise photosynthetic rate,promote cucumber growth and yield of spring cucumber in greenhouse and it is recommended for higher production of cucumber.
