俗话说:“好葫芦出好瓢,好种子出好苗。”种子的优劣对庄稼是否丰收关系极大。农户自备的种子贮放时,要做到十不要。一、不要用塑料袋装。种子在贮存期间虽处于休眠状态,但仍进行呼吸作用。塑料袋不透气,用其装种子影响种子的正常呼吸,降低发芽率和发芽势。如种子含水量偏高,由于袋内不通风,多余的水分不能散失,温度还会生高,引起发霉变质。二、不要和地面直接接触。无论用麻袋、布袋或其它容器装种,都不宜直接放在地面上,以防种子受潮,降低发芽率。应用砖石或木板将种袋或其它容器垫高50厘米左右为宜。三、不要和农药、化肥混放。有的农药、化肥有一定的挥发性,其气体对种胚危害极大。若和种子同放一处,会使种子降低发芽率和发芽势。
As the saying goes: “a good gourd out of a good scoop, a good seed good seedlings.” The pros and cons of the harvest of crops is a great bumper harvest. Farmer-owned seed storage, to do ten do not. First, do not use plastic bags. Although the seeds are dormant during storage, they still breathe. Plastic bags airtight, with their installed seeds affect the normal breathing of the seeds, reducing the germination rate and germination potential. If the seed moisture content is high, because the bag is not ventilated, excess water can not be lost, the temperature will be high, causing moldy deterioration. Second, do not touch the ground directly. Whether sacks, cloth bags or other containers, should not be placed directly on the ground, to prevent the seeds damp, reduce germination rate. Application of masonry or wood to seed bags or other containers up to 50 cm high is appropriate. Third, do not mix pesticides and fertilizers. Some pesticides, fertilizers have some volatility, the gas is extremely harmful to the embryo. If the same place with the seeds, will reduce the seed germination rate and germination potential.
