我县地处小兴安岭南端,无霜期短,年积温在2400℃左右,冬季寒冷最低,温度可达-40℃左右,夏季最高温度达38℃左右,冬夏温差大。在这种自然条件下,怎样才能使种子安全过冬、度夏,是经营管理工作一项主要课题。1 首先要考虑库房建设1.1 房盖要不漏雨雪,最好设有保温棚,降低库房温度。1.2 门窗要设有合理封闭的防鼠雀措施。1.3 地面下最好要有通风道,一般要用地板为好,水泥地面要加有防潮层,地面墙壁要合理留有通风孔,种子堆下要加有20cm 高的垫木,创造这些条件才能较好的防
My county is located in the southern tip of Xiaoxinganling, frost-free period is short, the annual accumulated temperature at about 2400 ℃, the lowest winter temperature, the temperature up to about -40 ℃, the summer maximum temperature of 38 ℃, temperature difference between winter and summer. Under such natural conditions, how to make the seeds safe for the winter and summer is a major issue of management. 1 first of all to consider the building of the Treasury 1.1 cover leak or snow, it is best to have thermal insulation shed to reduce the temperature of the Treasury. 1.2 doors and windows should be reasonably closed anti-rat warbler measures. 1.3 Under the ground there are best to have ventilation, generally use the floor as well, to be added to the concrete floor moisture barrier, the ground walls to be reasonably left vents, seed piles to add 20cm high mat, to create these conditions Better defense
