过去,草花生产者大都自己留种,即使购买种子,也是价格很便宜的国产种子,种子成本很低。育苗时大多撒播,很少有人因为成本问题而关注种子的发芽率与成苗率,也就是说很少重视草花的育苗技术问题,一般都是靠天吃饭,任其自然。然而近几年,随着园林绿化质量、水准的不断提高,人们对绿化美化用植物材料质量要求也提高了,特别是花卉品种的花色、形态、花期长短、对养护管理的要求等等,以致越来越多的草花生产者购买进口花种,采用高新技术来育苗生产。进口草花种子的价格比较贵,所以生产者迫切需要提高育苗技术,提高出苗率和壮苗率,有效降低生产成本、提高成品花的品质质量。北林科技经过实际操作,总结了一套适合小型苗圃生产者的实用育苗技术。我们的统计结果显示:常用的诸如一串红、万寿菊、矮牵牛、彩叶草等花卉进口种子,采用这种技术育苗,成苗率都能达到85%以上。
In the past, grass flower producers mostly kept their own seeds, even though the purchase of seeds was a cheap domestic seed with a very low cost of seeds. Feeding seeding most sowing, few people pay attention to the cost of the seed germination rate and seedling rate, which means that little emphasis on flower seedling technology, are generally dependent on the weather, let it be. However, in recent years, with the continuous improvement of landscaping quality and standards, the quality requirements of plant materials for afforestation and beautification have also been raised, especially the flower color, shape, flowering period, requirements for conservation and management of flower varieties, etc. More and more grass flower producers buy imported flowers and adopt high technology to nurture seed production. Imported grass flower seeds more expensive, so producers urgently need to raise seedling technology, improve the emergence rate and strong seedling rate, reduce production costs and improve the quality of finished flower quality. North Lin technology through practical operation, summed up a set of practical nursery seedlings for small nursery producer technology. Our statistical results show: commonly used flowers such as string of red, marigold, petunia, colored leaf grass and other imported seeds, seedlings using this technology, the seedling rate can reach more than 85%.
