Abstract:
Using single factor randomized block design，nine different treatments were set up by mixing wormcast with peat and perlite in different proportions.The physical and chemical properties of different treatment mixtures were analyzed.The effects of different treatments on the seedling breeding of a new pumpkin variety ‘Shengyu 307’ were discussed.The results showed that T0 treatment (pure wormcast) had larger bulk density，less total porosity，poor aeration，high phosphorus，potassium and low nitrogen；T4，T8 treatment (without perlite) had more nutrient content，higher EC value，but poor aeration；T1，T5 treatment (high proportion of perlite) had better aeration，but poor water holding capacity and low nutrient contentl；T7 and T3 treatment (wormcast，peat and perlite account for a certain proportion each) had overall coordination of physical and chemical properties.They were not only certain water and fertility retention，but also certain aeration，moderate water-air ratio，more nutrient content，higher EC and higher fertilizer supply performance.The seedling growth of ‘Shengyu 307’ was significantly affected by different treatments.T7 treatment (wormcast 66.7%，peat 26.7%，pearlite 6.7%) resulted in strong seedlings，with stem diameter 4.8 mm，leaf area 33.17 cm2，total root length 12 cm，root dry mass 0.226 g and strong seedling index 0.93.These indexes were significantly higher than or higher than other treatments.T7 treatment can be used as seedling medium of ‘Shengyu 307’.
