摘要:

橡胶蒲公英被认为是应对天然橡胶紧缺状况的首选乳胶来源替补作物。为了进一步了解其作为经济作物的农田生产潜力,基于检索国内外研究开发进展进行综合分析。结果表明:橡胶蒲公英根系不仅含有乳胶、而且含有菊粉等功能性成分,具有增产增效增值开发潜力。然而,产业化发展面临的首要瓶颈问题是缺乏规模化高产高效生产的农作措施,以致根胶产量低、种植成本高、生产效益差。因此,必须加快以提高根系产量和乳胶含量为目标的农艺、农技相结合的综合研发,重点包括:农艺性状及其适应性的驯化改良、田间机械化直接播种技术与适宜耕作种植方式、群体构建形成与田间杂草防控、生长发育动态与水肥优化调控、根胶物质形成积累与根系适期收获等,最终集成适合不同区域资源禀赋特点的良种良法配套的种植模式及技术体系,将有利于推进橡胶蒲公英发展成为切实可行的产业化经济作物。

Abstract:

Rubber dandelion (Taraxacum kok-saghyz) (TK) is considered the best alternative and promising rubber-producing crop for a severe shortage of natural rubber (NR). In order to further understand the potentiality of TK as an economic crop for industrialization, a comprehensive analysis was carried out based on the retrieval of the development and research progress at home and abroad. The results indicated that TK had a great potential in the increase of root-latex output and economic benefits for exploitation and development, because its root contained not only high-quality latex but also other healthy and functional food additives, such as inulin. However, the primary bottleneck problem of the industrializing development is lack of feasible agronomy measures with high-yield and efficiency, resulting in low root-rubber yield, high production cost and low production efficiency. Therefore, it is necessary to target increasing root yield as well as root latex content to accelerate the research of both agronomic traits and cultivating measures on TK cropping in field. The focuses of research are as follows: domestication and improvement of agronomic traits and their adaptability, mechanized direct seeding techniques in field and suitable planting patterns with tillage, plants population formation and prevent from field weeds developing, plant growth rhythm and optimized ways of fertilizing and watering, accumulation and distribution of functional matter and proper harvesting period, and so on. Finally, to integrate planting models and technical systems that are suitable for the characteristics of resource endowment in different regions will be conducive to promoting the development of TK into a feasible industrial economic crop.
