植物物候是植物对环境条件特别是温度条件的具体反应。油橄榄花的物候研究,是研究油橄榄生态适应性的重要组成部分之一。通过研究,能进一步了解油橄榄与环境特别是温度的关系,掌握变化的规律,从而采取有效的管理措施,以保证油橄榄的优质高产。今年我们观察了1975年定植的9株卡林品种开花的情况,小结如下:一、花的物候期1.物候期标准:现蕾期:在花序的分枝顶端可明显地见到一个个的小花蕾。初花期:全株5％的花朵开始开放。盛花期:全株50％以上的花朵开始开放。终花期:全株90％以上的花朵已开放。2.观察结果:在我区,油橄榄现蕾期是4月中旬,盛花期是5月中旬,终花是5月中下旬。盛花期很短,只4天。为了提高座果率,增
Plant phenology is the plant’s response to environmental conditions, especially temperature conditions. The study of the phenology of the olive flower is one of the important parts to study the ecological adaptability of the olive tree. Through the study, we can further understand the relationship between the olive and the environment, especially the temperature, master the rules of change, so as to take effective management measures to ensure the high quality and high yield of olive. This year we observed the flowering of 9 strains of Carlin colonies planted in 1975, summarized as follows: First, the phenological period of flowers 1. The phenophase standard: Budding: the top of the inflorescence can be seen clearly one by one Small buds. First flowering: 5% of the whole plant flowers began to open. Flowering: more than 50% of the whole plant flowers began to open. Final flowering: more than 90% of the whole plant flowers have been opened. 2 observations: In my area, olive bud stage is mid-April, full-flowering is mid-May, the final flower is mid to late May. Florescence is very short, only 4 days. In order to improve the rate of fruit, increase
