经营好天然次生林,对加快建设我省后备资源基地具有重要意义。为探索间伐扶育对次生林生长的影响,给合理地培育次生林提供技术依据,于1977—1978年在吉林地区兴隆川林场设置了间伐试验标地。于1982年进行了全面复查,现将试验结果分析如下: 一、试验地自然环境试验地位于磐石县兴隆川林场,座标为东经126°7′—126°20′,北纬43°12′—43°19′试验地属于吉林哈达岭的南麓低山丘陵区,相对高差200米左右.多为鸡爪埠地,最高山为大荒项子,海拔832米。土壤主要为暗棕壤,鸡爪岗多为白浆土,全年无霜期为115—120天。境内原有森林植被为红松阔叶混交林,现有森林主要是解放后封山育林而生长起来的天
Management of natural secondary forest, to speed up the construction of reserve base in our province is of great significance. In order to explore the impact of thinning and nurture on the growth of secondary forest and provide technical basis for reasonable cultivation of secondary forest, a thinning test plot was set up in Xinglongchuan Forest Farm of Jilin Province from 1977 to 1978. A comprehensive review was carried out in 1982 and the test results are as follows: I. The experimental natural environment test site is located at Xinglongchuan Forest Farm in Panshi County with the coordinates of 126 ° 7’-126 ° 20’E and 43 ° 12’- 43 ° 19 ’belongs to the hilly area in the southern foot of Mount Hadar in Jilin Province with a relative height difference of about 200 meters, mostly for Jijiaobu and the highest mountain is a big wilderness item with an elevation of 832 meters. Soil is mainly dark brown soil, chicken claw mostly white soil, the annual frost-free period of 115-120 days. The territory of the original forest vegetation is mixed Korean pine broadleaved forest, the existing forest is mainly closed after the liberation of the Hill to grow and grow the day
