经验证明,引种是提高农作物产量的一个有效途径,又是符合多快好省方针的好方法。但是,引种成功与否与引种地区自然气候因素(如温度、光照、霜期等)和品种类型生态条件都有直接的关系。我们遵循“内因是变化的根据”和“实践第一”的观点。于1963～1965年,从南北地区引入具有代表性的属于不同生态类型的花生品种共三十三个,系统地观察了这些不同类型品种,在锦州地区自然条件下,出苗、开花、荚果发育、成熟等物候性状和经济性状及产量的变异规律。现将其初步研究结果,以花生生态类型为单位概述如次。
Experience has proved that introduction is an effective way to increase crop yields and is a good way to meet the principle of “more speed and better quality”. However, the success of the introduction and the introduction of natural climate factors (such as temperature, light, frost, etc.) and the type of ecological conditions have a direct relationship. We follow the view that “internal causes are the basis of change” and “practice first.” From 1963 to 1965, a total of 33 peanut varieties belonging to different ecological types were introduced from the north and south regions. The different types of cultivars were systematically observed. Under the natural conditions in Jinzhou, the emergence, flowering and development of pods, Maturity and other phenological traits and economic traits and yield variation. Now its preliminary findings, with peanut ecological type as a unit summarized as follows.
