本文针对班克松引种栽培、结实后的苗木繁育和野外造林技术进行了研究。结果表明,种子通过低温催芽后,10±1g/m2播种量、0.5cm覆土厚度、湿润的床面可以提高种子的发芽率和存活率;叶面喷施磷钾肥对苗木后期生长和提高木质化程度具有促进作用。S1-1型的班克松苗木造林其缓苗时间、须根发育、地径、平均高生长、成活率和保存率等指标均优于S2-0型。改造后班克松种子千粒重达到3.65g,比改造前增加0.3g。
In this paper, the introduction and cultivation of Magnolia bungeanum, seedling growth after solidification and field afforestation techniques were studied. The results showed that seed germination rate and survival rate could be improved by 10 ± 1g / m2 seeding rate, 0.5cm soil cover thickness and wet bed surface after seed germination at low temperature. Phosphorus and potassium fertilizers application on the seedling growth and lignification Degree has a catalytic role. The rate of seedling growth, root growth, average height growth, survival rate and preservation rate of S1-1 type Bark was better than that of S2-0. After the transformation of Bankers pine seed weight reached 3.65g, increased 0.3g than before the transformation.
