落叶松,极喜光,根系发达,生长快,材质好,用途广,是华北地区主要用材造林树种之一。落叶松造林在“三北”防护林、京津风沙源治理及“再造三个塞罕坝林场”工程中占有重要位置。塞罕坝机械林场总场于2001年建成温室一座,主要用于造林苗木的培植,以缩短育苗周期。经过试验,在高寒地区,落叶松的温室穴盘育苗获得成功,现总结如下。一、育苗环境 1、调温温室:采用胖龙公司生产的文洛式3脊6联栋三层中空聚碳酸酯板钢架结构的温室,
Larix, very light, developed root system, rapid growth, good material, wide use, is one of the main timber afforestation species in North China. Larix afforestation occupies an important position in the protection of “Three Norths” shelterbelt, Beijing-Tianjin sandstorm source management and “Rebuilding Three Saihanba Forest Farm” projects. Saihanba mechanical farm total field built in 2001, a greenhouse, mainly used for planting seedlings to shorten the breeding cycle. After testing, in the alpine region, larch greenhouse seedling success, are summarized below.
