迷迭香扦插育苗试验初报

迷迭香(Rosmarinus officinalis L.)是唇形花科迷迭香属植物,是一种多年生常绿亚灌木,为观赏及芳香油植物,该植物已成为全球普遍重视的资源植物之一。迷迭香种子发育不良,种子萌发力极低,故通常采用无性繁殖法育苗,在生产中为了降低成本,节约资金,现阶段主要采用扦插法繁殖进行苗木生产。近年来,国内外对于迷迭香精油及抗氧化剂的研究报道及论文很多,但对迷迭香育苗技术报道却较少。开展该课题研究,对迷迭香的育苗技术进行研究,通过试验记载、观察、田间管理,为迷迭香种植提高育苗成效,降低成本,增加农民收入,为中国天然抗氧化剂的生产保障优质充足原料供应,具有重要意义。试验研究在玉溪对迷迭香进行扦插试验。迷迭香分别扦插在基质为菜园土的苗床上、用纸杯装菜园土扦插、在泥炭土:珍珠岩为2:1的基质上扦插,试验结果表明,试验结果表明,春季扦插成活率高,成活时间短,扦插苗生长健壮,在菜园土上扦插成本低,用纸杯装土扦插,成活率95%￣99%,且苗生长健壮。在泥炭土:珍珠岩为2:1的基质上扦插结果,嫩梢作插穗在插后8d开始生根,25d全部生根,生根率99.5%。以上各种扦插方法培养的扦插苗移栽成活率均在95%以上,没有明显区别,可见3种方法扦插育苗都具有成活率高的特点,但采取什么方法,以成本和已有的生产材料及技术而定。

Research on Implantation Technology of Rosemary

Rosemary belongs to the labiatae and belongs to years-living family of the short shrub type or years-living fragrant family plant of the crawl type. The seed development of Rosemary is bad, its seed germination dint is very low, so the vegetative propagation method is usually adopted to breed the seedling. In order to decline the costs and economize fund in the course of production, cutting is mainly adopted to nursery stock production in present stage. In recent years, although there are many research thesis and versions of essential oil and antioxidant to Rosemary at home and abroad, there is little report on the seedling raising techniques especially no report on the research of the relationship between the fertilization level and output in planting. In order to raise output value of the unit area , heighten the raise seeding efficiency to decline the cost, increase farmers'' earning, which can be worked through the method of test record, observing, field management, the output survey, the research on this subject that the seedling raising techniques is so rich in significance for this field. The stroma containing peat soil and perlite (2:1) for cutting experiment is the vegetable garden stroma seedbed, by which is packed the scraped paper cup. The twig and the hard tress are cut in the soil respectively. The results of the experiment indicate that the survival rate is high on spring;but the period of living is short. Seedling after cutting grows strong; the cost for cutting in the vegetable garden soil is less; The surviving rate of seedling after transplantation through various methods of cutting above is over 95% on average, having no obvious distinction. Therefore, the common characteristic of the three methods of cutting that survival rate is high. However, What method is taken, which depends on costs, technology and existing production materials.
