油松种子的采收时间,种子的发育成熟程度决定种子质量,越是早采的种子发芽率越低。在油松种子收购季节,正规检验团时间长难以进行,要保证收购种子的质量等级准确,就必须熟练掌握现场检验技术。商洛种苗站根据多年实践经验,总结出油松种子“一看、二摸、三剥、四切、五染”的现场测定技术,对各地收购种子保证质量很有益处,现介绍于下: 一看是指目测。观察种子外表、色泽等,以此确定是新种子还是陈种子,是坏种子还是好种子。劣质种 The harvest time of pine seeds, seed development and maturity determine the quality of the seeds, the more early mining seed germination rate is lower. In the pine seed purchase season, the formal inspection mission is difficult to carry out for a long time. To ensure the quality level of the purchased seeds is accurate, on-site inspection techniques must be mastered. Based on years of practical experience, Shangluo Seedling Station concluded that on-the-spot measurement technology of Chinese pine seeds “one look, two touch, three peel, four cut, five dyeing” A look is the visual. Observe the seed appearance, color, etc., in order to determine whether the new seed or the Chen seed is a bad seed or a good seed. Poor quality
