Abstract:
Muskmelon(Cucumis melo L.var.makuwa Makino) cultivar ‘Ribentianbao’ was used as the experimental material,effect of different volume mixed substrate of coir dust and perlite on growth and quality of melon seedling cultured in nutrition bowl were studied in order to support reference base for determining suitable volume of mixed substrate of coir dust and perlite in raising soilless melon seedling.The results indicated that plant height,leaf number,leaf area,dry and fresh weight of shoot and root,root to shoot ratio,round seedling index,photosynthetic rate,transpiration rate,root activity of succinic dehydrogenase of melon seedling were all distinctly affected by different volume of raising seedling substrate.Thus it could be seen that growth parameters,assimilative accumulation,photosynthetic characteristics and root absorption function of seedling were affected,distribution property of assimilation and seedling quality also affected by raising seedling volume.Growth and development of seedling were restricted by deficiencies of water and fertilizer supply and cushioning of substrate when lesser volume of raising seedling substrate was used,while greater holding moisture capability of rhizosphere was not beneficial to growth and development of melon seedling which possessed resistance to drought when volume of raising seedling substrate was greater than 290 mL.It was preliminarily proved by this experiment that 290 mL was suitable substrate volume for raising melon seedling.
