油松是我省主要造林树种之一。建国以来全省营造大面积油松人工林,约有500万亩,年产种子750000kg,丰产年可达1500000kg,除满足本省育亩造林飞播用种外,大部分支援甘肃、陕西、山西、河北、河南、四川、湖北、江西等省区。为了进一步提高油松播种质量,保证用种,现将油松球果采收、种子调制与贮藏之技术要点总结如下。
Pinus tabulaeformis is one of the main afforestation species in our province. Since the founding of the People’s Republic of China, a large area of Pinus tabulaeformis plantation has been established, covering an area of 500 million mu. The annual output of seeds is 750,000 kg, and the annual output is up to 1,500,000 kg. Apart from satisfying the provincial afforestation and seeding planted by the province, most support Gansu, Shaanxi, Shanxi and Hebei , Henan, Sichuan, Hubei, Jiangxi and other provinces. In order to further improve the sowing quality of Pinus tabulaeformis to ensure the use of seeds, now the Pinus tabulaeformis recovery, seed preparation and storage of technical points are summarized below.
