对福建青冈种子进行不同贮藏方式、播种时间、切根等播种育苗试验。结果表明:播种时间以采种后第2~7 d及时播种较好;湿沙层积贮藏和冷藏处理反而降低出苗率和成苗率;切根处理可以提高苗木质量。福建青冈育苗的关键技术是及时播种和切根处理。最佳技术组合为:福建青冈采种水选后,经湿沙层积贮藏2~7 d,取出用指甲掐断根尖0.2~0.3cm;或水选种子直接播种,于6月中旬,利用锋利铁铲,在距离苗木5 cm处,呈45°斜切,切断主根的育苗方式。 The seeds of Fujian Cycads were stored in different ways, sowing time, cutting roots such as seedling nursery trials. The results showed that sowing time could be sown in time of 2 ~ 7 d after planting, and the storage and cold preservation of wet sand could reduce the germination rate and seedling rate instead. Stubble treatment could improve seedling quality. The key technology of Fujian Qinggang nursery is timely sowing and cutting. The best combination of techniques is as follows: After the water was collected from the Cyclobalanopsis glauca, 2 ~ 7 d of wet sand was used for storage, and the root tips were cut off with fingernails to 0.2 ~ 0.3 cm. Or seeds were directly seeded with water. In mid June, Shovel, at a distance of 5 cm from seedlings, was 45 ° beveled, cut off the main root nursery way.
