红松人工林结实丰产技术的研究

Study on the Yield of Pinus koraiensis Plantation Technology

通过对红松人工林分杈树的结实和生长情况调查,分析了林木分杈与生长、结实的关系。分杈树的胸径、树高、材积、结实量均高于林分平均值,利用这一规律,对红松人工林进行去头修剪,人为促进林木分杈,以提高红松结实量。结果表明,对林分密度适宜的林分去头修剪后,可明显增加林分的结实量,最高可提高186.8%,经验经济效益十分可观。

Ations of the fruiting and growth of the branch tree of Pinus koraiensis plantation,the relationship between the branch and the growth and fruiting was analyzed.The diameter,height,volume and yield of the branch tree were higher than the average value of the stand.Using this rule,the artificial pruning of Pinus koraiensis plantation was carried out in order to increase the yield of Pinus koraiensis.The results showed that the stand with suitable stand density was pruned after pruning.The yield of the stand could be increased obviously,the highest value could be increased by 186.8%and the empirical economic benefit was very considerable.
