经15年飞播追林试验证明,漆树在我省秦巴山地,渭北石质山地,陕北丘陵沟壑区海拔1000～1800m的中、低山地区,年降水量600mm 以上地区均可飞播造林。品种应选大木漆。种子脱蜡处理以干法为好。播量以每公顷4.5～7.5kg 为宜。华山松在海拔1500～2100m 的中、高山区,播后50天内降水量不少于120mm,相对湿度不低于70%,日平均气温不低于12℃地区均可飞播造林。飞播用种不得低于国际Ⅱ级种子。每公顷播量26.35kg,播前需进行防护处理,播期以3月下旬到4月上旬为宜。漆、松混播可以充分适应立地条件,获得均匀的成苗效果,形成团、块状针阔混交林。其平均成林面积率可达45.8%。
After 15 years of aerial broadcast forest test shows that the tree in Qinling Mountains in our province, Weibei stony mountainous areas, northern Shaanxi hilly area elevation 1000 ~ 1800m in the middle and low mountain areas, annual precipitation above 600mm can be aerial sowing. Variety should be selected wood paint. Dewaxing of seeds is better with dry method. Seeding rate of 4.5 ~ 7.5kg per hectare is appropriate. Huashan pine can be sowed in the middle and high mountainous areas at 1500 ~ 2100m above sea level with precipitation not less than 120mm and relative humidity not less than 70% within 50 days after sowing, and daily average temperature no lower than 12 ℃. No less than the international level Ⅱ flight seeded seeds. Seeding per hectare 26.35kg, sowing before the need for protective treatment, sowing in late March to early April is appropriate. Paint, pine mixed broadcast site conditions can be fully adapted to obtain a uniform effect of seedlings, the formation of lumps, massive coniferous and broad-leaved forest. The average forest area rate up to 45.8%.
