초록

This study was conducted to obtain proper amount of solid swine manure and poultry manure in the beginning phase of Cornus kousa growth by investigating the initial germination, seedling growth increment, dry weight, chlorophyll content change, body nutrient uptake and chemical changes of soil according to the concentration of solid swine manure and poultry manure fertilization. When treated with solid swine manure and poultry manure, seed germination rate was the highest in the control. However germination rate showed a tendency to decrease when treated with high concentration of swine manure and poultry manure. The survey results of the growth increment were all higher than that of the control. At the 1.0% treatment of both swine and poultry manure, the seedling height growth was highest. Poultry manure treatment made higher result than swine manure treatment at each treatment. Dry weight was the highest at the 1.0% treatment by both swine and poultry manure. Dry amount declined sharply at the 2.0% treatment. Poultry manure was higher in weight than swine manure at every treatment. Chlorophyll content was the highest at the 1.0% treatment by both swine and poultry manure, but declined sharply at the 2.0% treatment. The survey content was higer than that of the control. The amount of nutrients absorbed in the seedling body was generally high at the 1.0% treatment of swine manure and poultry manure. For the planting soil of Cornus kousa the higher concentration of swine manure and poultry manure was, the lower pH became. However, nitrogen, got higher. available phosphoric acid, exchangeable K, Na, and Mg got higher.
