胡杨种子非常小,种皮薄,易吸湿,极难贮藏。几年来,我们用氯化钙贮藏胡杨种子,其发芽率达30—46％,当地(1982年和1983年盖膜育苗)和东北、天津塘沽区用这种种子育苗,发芽和出苗均好。现将其贮藏方法简介于下。 8月,采收充分成熟的胡杨蒴果,脱粒阴晒,经常翻动,当手搓种子有沙性时,立即贮藏(瓶贮或袋贮)。氯化钙用量为种子重量的1/10,用过的或干燥不充分的氯化钙须焙干后再用。瓶贮时,用小口玻璃瓶或塑 Populus seeds are very small, thin seed coat, easy to absorb moisture, very difficult to store. In recent years, we use poplar seeds with calcium chloride storage, the germination rate of 30-46%, the local (1982 and 1983 cover film nursery) and the Northeast, Tianjin Tanggu use of this seedling, germination and emergence are good. The storage method is now below. In August, full-ripe Populus euphratica capsules are harvested, threshed and sun-dried, and often flipped. Immediate storage (bottle storage or bag storage) occurs when the hand-rubbing seeds are sandy. The amount of calcium chloride is 1/10 of the weight of the seeds, and the used or insufficiently dried calcium chloride should be dried before reuse. Bottle storage, with small mouth glass bottles or plastic
