科学存放农作物种子,可以延长种子的寿命,保持其旺盛的生命力,为壮苗、早发、高产提供先决条件。若存放不合理,就会造成种子混杂、霉烂、变质,在短时间内丧失生命力。播种后造成严重缺苗、断垄、苗势弱,或出苗后短期内死亡等,给农民带来不应有的损失。因此,存放农作物种子具体应做到以下几点。一、忌高温。存放农作物种子要求环境温度最好在10℃左右,温度过高,使种子的呼吸作用旺盛,会过多地消耗自身的营养,降低种子的发芽率。二、忌潮湿。种子受潮湿后,水份提高,容易发生霉变,降低发芽率,因此,不宜直接放在地上或潮湿的地方。三、忌烟熏。种子长时间受到烟雾熏,就会使其活性大大降低,发芽率削弱。四、忌混放。种子不能与一般食用粮食混放在一起,因为不少作物的种子与食用粮食不宜区分,稍不注意就会造
The scientific storage of crop seeds can prolong the life of the seed and maintain its strong vitality, providing the precondition for strong seedling, early onset and high yield. If stored unreasonable, it will cause the seeds mixed, rotten, deterioration, loss of vitality in a short time. Severe lack of seedlings after sowing, broken ridge, weak seedling, or short-term after emergence of death, etc., to farmers an undue loss. Therefore, the specific storage of crop seeds should do the following. First, avoid high temperature. Storage of crop seeds requires the best ambient temperature around 10 ℃, the temperature is too high, so that the strong respiration of the seeds, will consume too much of their own nutrition, reduce seed germination rate. Second, avoid wet. After the seeds are wetted, the water is increased, mildew is prone to occur and the rate of germination is reduced. Therefore, the seeds should not be placed directly on the ground or damp places. Third, avoid smoking. Prolonged smoke smoked seeds, it will greatly reduce the activity, the germination rate weakened. Fourth, avoid mixed. Seeds can not be mixed with the general consumption of food, because many crops, seeds and food should not be distinguished, a little careless will be made
