Abstract

To scientifically manage the short-period industry-use forest of cold-resistant Eucalyptus and eradicate the conflicts among instant growth of Eucalyptus , degraded forestland and freezing injury , fast-growing and highyield forest base of Eucalyptus dunnii was built in Xudun Town of Jianou City in Fujian Province in 2004 to test the humic acid as special organic fertilizer for Eucalyptus .Results showed that frostbite rate and grade , and freezing injury index of Eucalyptus applied with the special fertilizer decreased by 23.9 %-43.5 %, 25.0 %-50.5 %and 32.4 %-49.7 % respectively .Tree height , DBH, crown and timeber volume of forest applied with the fertilizer increased by 6.3 %-26.6 %, 14.7 %-37.2 %, 6.5 %-18.8 % and 42.9 %-136.7 % respectively .Among them , compound fertilizerwith 500 g special humic acid for Eucalyptus and 10 g compoundmicrobial agent as basal fertilizer and 500 g No.2 special humic acid for Eucalyptus dressing as dressing had the best effects on cold resistance and growth stimulation .It was an ideal fertilizer for Eucalyptus dunnii in the north of Fujian .[ Ch , 5 tab .11 ref .]
