| Abstract/Contents: | "Potassium can significantly improve the cold hardiness of centipedegrass. On one hand, potassium can significantly strengthen the activity of SOD enzyme, especially effect of 4.5~6 g/m2 K2O is significant at the 0.01 level. On the other hand, potassium can decrease the relative electrolyte leakage of centipedegrass. Electrolyte leakage between different fertilization treatments and the control is significantly correlated to the SOD enzyme activity. In proper time, applying potassium with proper quantity not only strengthens SOD enzyme activity, but also decreases the relative electrolyte leakage, and protects the integration of membrane, which improves the cold hardiness of centipedegrass at a certain degree. Therefore, applying potassium is feasible management technique to improve the cold hardiness of centipedegrass. The appropriate quantity is 6 g/m2 K2O, and limited quantity in several applications are best." |
