选一地势高且干燥,背阴的地方挖沟,沟深60cm,长宽以种子多少而定。冬季不太冷的地区,也可将种子堆积地面,便于检查。沙藏时沟底抚辅一层湿沙,然后使种子与湿沙相间层积,或将种子和湿沙混合存放均可。用沙比例以种子大小而不同,大粒种子需湿沙15倍,小粒种子需5倍。沙的湿度以手握成团,一触即散为度。当堆放到离地面约10cm时,可用湿沙将沟填平,再用土培好并高出地面,最好于沟中间插埋一捆秫秸,以利通气。少量种子不宜沟藏时,可用木箱沙藏放于地窖内,或在窖内用砖砌成一小池沙藏亦可。但窖温必须在0—5℃左右,并保持一定湿度。
Choose a high ground and dry, shady digging ditches, ditch deep 60cm, length and breadth to seed size. Winter is not too cold areas, but also the accumulation of seeds on the ground, easy to check. Sand reservoir at the end of the ditch Fu Fu a layer of wet sand, and then make the seeds and wet sand laminated, or the seeds and wet sand can be mixed storage. With the proportion of sand to seed size and different, large seeds need wet sand 15 times, 5 times the need for small seeds. The humidity of the sand is cluttered by the hand and scattered as degrees. When stacked to about 10cm from the ground, the wet sand can be used to fill the trench, and then use the soil to cultivate well above the ground, it is best to insert a bundle of straw in the middle of the trench to facilitate ventilation. When a small amount of seeds should not be dug, it can be stored in a cellar with a wooden sand box, or bricked into a small pool of sand in the cellar. However, pit temperature must be about 0-5 ℃, and maintain a certain humidity.
