我局从 1994年开始对六十年代初冠下更新红松形成的阔叶红松林实施了果园林经营方式 ,本文对土壤肥力、林分密度、林龄、气候条件等影响红松果林结实的主要因子进行了研究。结果表明 ,土壤肥力与结实期关系不显著 ,林分密度、林龄、气象及采种时间等项因子与产量、质量关系十分密切 Since 1994, our bureau implemented the management mode of orchard on the deciduous broad-leaved Korean pine forest which is under the crown of the regenerated korea pine in the early 1960s. This paper has the influence on the soil fertility, the stand density, the age of the forest, the climatic conditions and so on. The main factors were studied. The results showed that there was no significant relationship between soil fertility and grain-filling stage. The factors such as stand density, stand age, meteorology and planting time were closely related to yield and quality
