摘要:
高海拔地区人工种植的中药材续断产量已不能满足市场增长需求，为开辟新的种植区域，对续断在低海拔地区栽培技术进行了初步探索。发现续断在德宏低海拔地区种植当年生长迅速，且冬季地上部分无枯萎现象；根系生长正常，主根明显；病虫害不严重，仅有少量蚜虫危害。根据续断的生物生态学特性分析在德宏低海拔地区种植可能遇到的问题，提出解决方案和应对措施，制定栽培方案并应用于实际生产，并总结了在德宏低海拔地区种植续断的初步技术。
Abstract:
In order to develop breakthrough fragrant rice varieties with multiple optimal integrations, the main work objectives include genetic analysis of fragrant rice, germplasm innovation, construction of backbone parents, and breeding of fragrant rice (Oryza sativa Geng Grop) varieties. A core resource library of fragrant rice (Oryza sativa Geng Grop) consisting of 62 resources was constructed, and the fragrant rice core germplasm Sui 9230 was created. The Rice Quality Breeding Research Institute of Suihua Branch of Heilongjiang Academy of Agricultural Sciences established a comprehensive breeding module by crossbreeding Suijing 4 (Sui9230), the first fragrant rice variety in Heilongjiang Province,as the female parent and Dongnong 424 as the male parent, breaking through genetic burdens and technical bottlenecks such as aroma, early maturity, high quality, disease resistance, high yield, and wide adaptability, and selecting a new fragrant rice variety Suijing 309. Participated in the second temperate zone trial in Heilongjiang Province from 2018 to 2019, with an average yield of 8 059.6 kg·ha-1, an increase of 8.8% compared to the control variety Longjing 21; In 2020, participated in the second accumulated temperature zone production experiment in Heilongjiang Province, with an average yield of 8 568.1 kg·ha-1, an increase of 8.7% compared to the control variety Longjing 21. This variety has excellent agronomic traits, including rich aroma, high quality, high yield, and strong stress resistance. It is suitable for planting in the second accumulated temperature zone of Heilongjiang Province, which requires an active accumulated temperature of ≥ 10 ℃ and 2 500 ℃.
