Abstract: The thinning intensities comparision tests were conducted on two slash pine plantations of 6 a and 9 a,with planting densities of 2 500 and 1 110 trees/hm2 respectively in NE Jiangxi Province. It was found after 5 years,the reserved tree density of 1 275 trees/hm2 for the first and 525 trees/hm2 for the second would significantly hasten the diameter and standing volume growth ,improve the stand structure,and effectively shorten the rotation age. The planting density and first thinning age of slash pine plantations were discussed, it was considered suitable to plant about 1 500 trees/hm2 and carry out moderate to heavy thinning in about the 10~12th year for the production of large dimension timber of slash pine.
