| 摘 要： | 从利用籼粳亚种拓宽种质资源技术、理想株型种质资源培育技术、分子育种技术和应用常规育种技术4个方面介绍了黑龙江省优质超级稻育种技术的研究进展。从土壤培肥技术、钵育壮秧技术、合理密植技术、井水提温技术、平衡施肥技术等方面探讨了寒地优质超级稻品种的各种性状得以展现要配套的高产栽培技术,提出合理密植是寒地超级稻建立超高产经济结构的基础,是寒地超级稻株型更为理想、叶片更为直立的高光效的必然,是走以成熟为主的栽培技术路线"促早熟、高产、优质"并举的保证。寒地优质超级稻育成的品种有龙粳14、龙稻5号、松粳9号等。

| Abstract: | This paper focused on the following four aspects: Firstly,subspecies of rice indica and japonica were used to broaden germplasm resources technology.Secondly,the culture technology was based on germplasm resources of ideal plant type.Thirdly,molecular breeding technology was used.Fourthly,conventional breeding technology was applied to produce super-high-yield rice materials.The research progress of rice high quality breeding technology in Heilongjiang Province was introduced.The technology of soil fertilization,strong seedling culture,suitable planting density,rising temperature by well water,and balanced fertilization were studied with relation to all kinds of trait performances of high quality super rice varieties in cold land.The results showed that suitable plant density was the basis for establishing super-high-yield structure,with high-efficient photosynthesis in the condition of ideal plant type and upright leaves.Promoting prematurity,high-yield,and high-quality were important.The achievements of super rice breeding in cold land were introduced: Longjing 14,Longjing 5 and Songjing 9 et al.The high quality of super rice research in Heilongjiang Province was expected.The development direction of high-quality super rice research and its breeding objective were proposed. |
