腊月梅花红如珊,三月桃李正芬芳,六月荷花池中秀,八月中秋桂花香。在植物世界中,为什么不同植物在不同的季节开花呢?植物开花要求哪些外界条件呢?内在的物质基础又是什么呢? 由于农林业和园艺实践的需要,人类自古以来一直迫切希望揭露自然界的这个大秘密:植物开花的规律究属若何?几千年来,人类的农业生产一直按照老规矩办事:春种秋收,冬播夏收。你想吃西瓜或菜豆那只有等到夏天。要看菊花,就得等到秋天。
The lunar plum blossoms are red, March peaches and plums are fragrant, June lotus ponds are in the middle of the month, and in mid-Autumn autumn, sweet-scented osmanthus flowers. In the plant world, why do different plants bloom in different seasons? What external conditions are required for plant flowering? What is the internal material basis? Because of the needs of agroforestry and horticultural practices, humans have been eager to expose the natural world since ancient times. This big secret: What are the laws of plant flowering? For thousands of years, mankind’s agricultural production has been working in accordance with the old rules: Spring harvest, winter sowing and summer harvest. You only want to eat watermelon or kidney beans until summer. To see chrysanthemum, you have to wait until autumn.
