Abstract:
The pot experiment was adopted to study the effect of thermal drying product of anaerobic digestion sludge on Ranunculus asiaticus growth，such as survival rate,plant height,flower diameter,dry matter accumulation in aboveground and so on.The results showed that there were some risks of the application of thermal drying product of anaerobic digestion sludge seedling to survival and growth of Ranunculus asiaticus.The survival rate of seedling was generally low which applied of the thermal drying product of anaerobic digestion sludge.Fifteen days after the first transplanting seedling the dead seedling were replanted.After filling the gaps with seedlings,the application of thermal drying product of anaerobic digestion sludge promoted the increase of crown diameter and dry matter accumulation in aboveground within the range of less than or equal to 33%.It showed obvious inhibition effect when the usage of the thermal drying product of anaerobic digestion sludge more than 33%,which was identical to rapid reduction of survival rate when the usage of the product more than 33%.
