1 June
Covered with 1-2 cm of moist(潮湿的) soil, the sunflower seed takes a few days to come up after being planted. Water has been added regularly and the hard seed coat softens in the damp soil to allow the first root to pierce downwards and the first leaves to push to the soil surface.
Reference version:
6 July
The root continues to grow downwards. The single stem grows hollow and smooth, revealing large spade-shaped leaves from the growing tip. Gradually, the plant's growing tip reveals the first hints of development of the flower bud. The plant stem becomes more woody.
26 July
About three weeks after the flower bud first becomes visible at the tip of the sunflower stem, it enlarges and begins to reveal a flattened disc(圆盘). Over the course of one week, the yellow ray florets, the disc florets bloom across the core of the sunflower blossom(开花期). It is yellow, looking beautiful.
Polish your observational journal about the sunflower.
