1.种子入库前必须进行细致全面的原始质量检验。检验项目;净度、纯度、水分、发芽势、发芽率、活力、种子带菌情况及有无虫卵潜伏,根据室检结果、及时处理以便选择高质量的种子贮藏。以下几种情况的种子是不适宜贮藏: ①发芽势低于80%,发芽率低于90%的中低活力种子;②淋雨色泽异常及成熟度不好的种子;③种子中有活动性害虫及大量虫卵且带菌种子多;④是杂交玉米种子瘦小、种皮皱缩,杂交稻种子谷壳表面含泥沙量大,裂壳半裂壳种占比例高的。 2.种子的晾晒:晒种应在4月中旬进行,选晴好天气晒透晒匀冷却入库,高温烈日季节确需晒种,种子
1. The seed must be carefully and thoroughly tested for its original quality before storage. Inspection items; Clarity, purity, water content, germination potential, germination rate, vigor, seed carrying status and the presence or absence of egg lurking, according to the results of laboratory tests, timely processing in order to select high-quality seed storage. Seeds are not suitable for storage in the following situations: ① medium-low vigor seeds with germination potential lower than 80% and germination rate less than 90%; ② seeds with abnormal rain color and poor maturity; ③ seeds with activity Pests and a large number of eggs and carrying seeds and more; ④ is the hybrid corn seed thin, seed coat shrinkage, hybrid rice seed hull surface sediment content, split shell half-split shell species accounted for a high proportion. 2. The drying of the seeds: bask in should be carried out in mid-April, the selection of sunny weather soaked in the sun cool storage, high temperature hot season really need to bask, seed
