一忌用塑料袋装种子。许多农户用化肥塑料袋贮存种子,这是不科学的。因为种子在冬贮期间虽然处于休眠状态,但呼吸尚未停止,若使用塑料袋装种子,极易造成种子呼吸功能下降,降低种子发芽率,甚至霉烂变质。二忌烟气熏蒸。种子如较长时间被烟气熏蒸,不仅会降低种子发芽率,还会造成播种后幼苗长势不良而发病。因此,种子不能贮藏在烟火较大的房屋里,也不能堆放在有毒气的露天场地。三忌雨淋雪盖。存放在房屋顶或露天的玉米果穗、稻穗等,顶部要用草帘子或塑料布盖好,以防被雨淋湿受潮,使种子变质。四忌忽冷忽热。入冬后,贮藏在室外的种子大冻后不要搬回暖室内,放在室内的种子也不要搬到室外,否则会降低发芽率。五忌种一子与地面直接接触。 Avoid using plastic bags of seeds. Many farmers use chemical fertilizer bags to store seeds, which is unscientific. Because the seeds during dormancy during dormancy, but the breath has not stopped, if the use of plastic bags of seeds, can easily lead to decreased respiratory function of the seeds, reducing seed germination rate, and even rotten metamorphism. Two bogey smoke fumigation. Flue gas as long as the fumigation of seeds, not only will reduce the seed germination rate, but also cause poor seedling growth after sowing. Therefore, the seeds can not be stored in larger houses with fireworks, nor can they be stacked in gas-filled open space. Three avoid snow cover. Stored in the roof or open-air corn ear, rice, etc., the top with grass curtains or plastic sheeting cover, so as to prevent damp rain damp, the seeds metamorphism. Four bogey suddenly hot. After winter, the seeds stored in the outdoor do not move back to the warm room after freezing, the seeds in the room should not be moved outdoors, otherwise it will reduce the germination rate. Five bogey planted a direct contact with the ground.
