玉兰(Magnolia denudata)不仅是中外驰名的庭园观花树种,而且其花蕾可入药,花片可熏茶,种子可榨工业用油。由于该树种种子休眠期长,育苗困难,我们特进行了玉兰种子湿沙层积育苗等项试验。当玉兰蓇葖果尖端裂开时,采后放于通风荫凉处,3～5天后,待果大部裂开时剥下种子,将其置于水中浸泡3～5天,等肉质的假种皮发软后,揉搓清洗出黑色或褐色种子,晾干后湿沙层积,置于2～15℃室内贮藏。试验结果指出,沙藏135天的,春播后第7天就开始出苗,15天内苗可出齐,出苗
Magnolia denudata (Magnolia denudata) is not only well-known Chinese and foreign garden flower species, and its flower buds can be used as medicine, flowers can be smoked tea, seeds can be squeezed industrial oil. Due to the long seed dormancy period of the tree species and the difficulty of nursery, we conducted special tests on the wet sand layer seedling cultivation of magnolia seeds. When the tip of Magnolia biloba cracked, put it into the ventilated shade after harvest, after 3 to 5 days, remove the seeds when most of the fruit is cracked, place it in water for 3 to 5 days, and fleshy seeds After the skin is soft, rub the black or brown seeds for washing, dry the wet sand and store in the room at 2 ~ 15 ℃. The results show that the reservoir of 135 days of sand, spring sowing on the first 7 days after germination, seedlings can be out within 15 days Qi, emergence
