Abstract:
Taking seeds of watermelon as material，with the substrate that was made up by cassava dregs，peat，perlite and vermiculite as main raw，and different levels of sheep manure mixed with camciumnitrate，slow-release fertilizer and ferrous sulfate as subsidiary raw，nine different substrates were screened，growth and physiological indexes of watermelon seedlings were comprehensively compared.The results showed that the watermelon seedlings planted in T3 (sheep manure，camciumnitrate，slow-release fertilizer，ferrous sulfate that respectively 10.0,1.5,1.5,10.0 kg/m3) substrate were better than other substrates.The emergence rate was 93.8%.The chlorophyll content increased by 37.7% compared with control.The data of plant height and stem diameter were significantly higher than that of control.The fresh and dry weight were both the biggest，increased by 50% and 51.3% compared with control.The seedling strength index was the highest and significantly higher than that of control.Secondly，that were T5(sheep masure，camciumnitrate，slow-release fertilizer，ferrous sulfate that respectively 30.0,1.0,1.5,3.0 kg/m3) and T2(sheep masure，camciumnitrate，slow-release fertilizer，ferrous sulfate that respectively 10.0,1.0,1.0,5.0 kg/m3) formula.
