随着樟子松在“三北”和全国引种成功，需种量急剧增加。培育优质高产的种子成为采种基地的重要任务。本研究在樟子松林分布的不同生态区内，研究球果产量与气象要素的相关性，认为影响山地樟子松林球果产量的主导因子是≥１０℃年积温和日照时数（热量），沙地樟子松林则是降水量。 With Pinus sylvestris in the “Three North” and the introduction of the success of the country, the need for a sharp increase in species. Cultivating high quality and high yield seeds has become an important task of planting base. In this study, the correlation between cone production and meteorological elements was studied in different ecological zones of Pinus sylvestris var. Mongolica. The dominant factors affecting the cone production of Pinus sylvestris var. Mongolica were ≥10 ℃ accumulated temperature and sunshine hours, Pinus sylvestris forest is the precipitation.
