朝阳县进行油松(Pinus tabulaeformis Carr.)飞播造林试验已经5年了,已初见成效,但是由于播期与降雨很难吻合,有时播后持续很长时间不降雨,种子遭受鸟、鼠的危害十分严重。本试验旨在通过油松种子涂不同颜色,试验观察,分析选择出哪种颜色的驱鸟、鼠效果最佳,寻求提高种子保存率、成苗率和降低飞播造林成本的途径。一、试验材料 1、油松种子:1950粒,产地是朝阳林场孙家湾工区,来自县林木种子站。种子品质指标,在14天中发芽率97％,在7天中发芽势71％。 2、染料:水彩颜料(12色)和胶水。为了提高颜色对种子表面的附着力,选择胶水作为粘着剂,二者混合后涂种。
The aerial seeding afforestation test of Pinus tabulaeformis Carr. In Chaoyang County has been for 5 years and has achieved some initial success. However, due to the difficulty of sowing dates and rainfall, sometimes the sowing does not rain for a long time and the seeds suffer from birds and rats Hazard is very serious. The purpose of this experiment is to apply different colors of Pinus tabulaeformis seeds, observe and analyze which kind of color birds are best for and to seek ways to improve seed preservation rate, seedling emergence rate and reduce the cost of aerial seeding. First, the experimental materials 1, pine seeds: 1950 grains, the origin is Sunjiawan Chaoyang Farm work area, from the county forest seed stations. Seed quality indicators, germination rate of 97% in 14 days, 71% of the germination potential in 7 days. 2, dye: watercolor paint (12 colors) and glue. In order to improve the color of the surface of the seed adhesion, select the glue as an adhesive, the two mixed after coating.
