研究了代表品种的熟期性、抗寒性和生育特性(即季节生育性、感光性、感温性及基本生长期,简称“三性一期”)等重要的气候生态特性。制订了适用于贵州的熟期性和“三性一期”的分级标准。用生态学——遗傅学观点讨论了品种的气候生态特性与品种原产地生态环境的密切关系。初步把贵州高原籼型水稻地方品种划分为四个气候生态型。对今后贵州高原水稻品种资源的评价和利用以及新品种选育工作提出了一些具体的建议。
The important climatic and ecological characteristics of the representative cultivars, such as maturity, cold resistance and reproductive characteristics (ie, seasonal fertility, sensitivities, temperature sensitivities and basic growth stages, referred to as “trigeminal period”) were studied. Developed suitable for Guizhou maturity and “three sexes” grading standards. Using the ecology-heritage theory to discuss the close relationship between the climatic and ecological characteristics of the breed and the ecological environment of the breed. The preliminary analysis of the indica rice landraces in Guizhou Plateau is divided into four climatic ecotypes. In the future, the evaluation and utilization of rice variety resources in Guizhou Plateau and breeding of new varieties are put forward some specific suggestions.
