河北省农林科学院谷子研究所,针对目前农业生产商品化、多样化和谷子本身的特点,推出谷子供种采用“小包装”方法,使良种良法溶为一体。几年来的试验示范结果表明,用小包装供种,定期进行种子更新,能彻底防止品种混杂退化,具有防病、增产的作用,而且还可延长良种的使用寿命,既有直接的经济效益,又有很大的社会效益,深受广大群众的欢迎。农民在长期生产实践中,积累了一条用异地换种办法解决谷子品种混杂退化的经验。研究表明,异地更换同一品种的种子,改变栽培条件,能增强种子的酶活性,提高抗病力。本项技术就是根据上述群众经验与研究结果提出的。通过跨大纬度的异地培育原原种,提高它的生活力,再以药剂或变温处理种子,配以所需的多元复合肥,用小包装供种。 Hebei Academy of Agriculture and Forestry millet Institute, in view of the current agricultural production of commercialization, diversification and the characteristics of millet itself, the introduction of millet for the species used “small package” method, so that a good method of Liang Rong dissolved. Several years of pilot demonstration results show that the use of small packaging for seed, regular seed renewal, can completely prevent the hybrid varieties of degradation, with disease prevention, increase production, but also can extend the life of good seeds, both direct economic benefits, Another great social benefits, welcomed by the broad masses. In the long-term production practice, peasants have accumulated an experience of using alternative ways to solve the problem of mixed degeneration of millet varieties. Studies have shown that changing the seeds of the same species in different places and changing the cultivation conditions can enhance the enzyme activity of the seeds and improve the disease resistance. This technology is based on the mass experience and research findings. Through the cross latitude off-site to cultivate the original species, improve its viability, and then pharmaceutical or temperature-treated seeds, together with the required multi-compound fertilizer, with a small package for the species.
