Effect of Different Substrate Compositions on Raising Large Seedling of Yellow Passion Fruit
[Objective]To screen suitable substrate composion of large seedling of yellow passion fruit,in order to provide references for farmers to raising large seedling of yellow passion fruit.[Method]Peat,coco peat,pearlite and yellow soil were used as seedling substrate compositions.Six large seedling substrates of yellow passion fruit were formed with substrate of peat and coco peat volume ratio of 2:1 as control.Seedling survival rate,plant morphological characters and fresh weight on different substrates were investigated to screen suitable seedling substrate compositions.[Result]On the 25th day after transplanting,seedling survival rate on six substrates reached 100％.Compared with the control,three substrates containing peat had better effect on raising large seedling of yellow passion fruit while two substrates containing no peat had poor effect.Seedling was the best while substrate of peat and pearlite volume ratio of 2:1 was used.On the 60th day after transplanting,plant height was 94.1 cm,stem diameter was 3.7 mm,leaf number was 15.6,fresh weight of the above-ground was 21.8 g,fresh weight of the under-ground was 9.2 g.All characters were the best.Effect of raising large seedling was significantly higher than that on control.[Conclusion]It was suggested that the best seedling substrate of yellow passion fruit was peat and pearlite volume ratio of 2:1.
