1.忌用塑料袋装种子。种子在冬季贮藏期间虽然处于休眠状态,但是呼吸作用尚未停止。如用塑料袋装种子,就妨碍了袋内空气与外界空气的交换,影响种子呼吸,降低种子发芽势和发芽率。如果种子含水量高,由于袋内不通风,种子就不会降低水分,还容易发霉变质。 2.忌突冷突热。贮藏在室外的种子,在大冻后不要再转入暖屋里。同时,存放在室内的种子,大冻后也不要再拿到室外。否则会降低种子的发芽率。 3.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和发芽势,还会因种子
1. Avoid using plastic bags of seeds. Although the seeds are dormant during winter storage, respiration has not stopped. Such as plastic bags with seeds, hinder the bag of air and outside air exchange, affecting seed respiration, reduce seed germination potential and germination rate. If the seeds have a high water content, the seeds will not reduce the moisture content and will be mildew-prone because the bags are not ventilated. 2. Avoid sudden sudden heat. Seeds stored outdoors should not be transferred to warm houses after they have been frozen. At the same time, the seeds stored indoors, do not get outdoors after freezing. Otherwise it will reduce the seed germination rate. 3. Do not smoke fumigation. If the fumigation of flue gas for a long time, not only will reduce the seed germination rate and germination potential, but also because of the seed
