樟子松是我国三北地区主要优良造林树种之一。天然樟子松林15-20年左右开始结实,球果第二年9-10月成熟。春秋两季均可采种,秋季在9月中下旬-11月上中旬,春季3月上旬-4月中下旬。但因树龄不同结果量和球果内种粒多少也有差异,采集球果是繁育樟子松的前提,科学采种可以为樟子松的成功繁育提供有力的保障。
Pinus sylvestris is one of the main afforestation species in the Three North regions of China. Natural Pinus sylvestris 15-20 years or so began to fruition, cones the second year of September-October mature. Spring and autumn can be planted in autumn, mid to late September - mid November, spring early March - April mid to late. However, due to the different age of fruit and the number of seeds within the cones are also different, collecting cones is the prerequisite for breeding Pinus sylvestris, scientific seed mining can provide a powerful guarantee for the successful breeding of Pinus sylvestris.
