These plants brought us a lot of fun when we were young. How many more can you remember?

The first plant is Solanum nigrum. When we were young, we ate less. We wanted to eat some wild fruits when we saw them, but adults would tell us that we could not eat them, so although we were greedy, we never ate these fruits. Solanum nigrum looks like a small grape, very attractive, green when it is not ripe, and turns purple and black when it matures. Although we don't eat this kind of fruit, we can use it to play with it. If we are curious, we will crush it and squeeze it out as ink. However, apart from dirtying his clothes, he was beaten up by his parents and nothing else happened. Who doesn't have a childhood? But I'm not the only one who's been beaten up!

The growth habit of Solanum nigrum L.: suitable temperature for growth is 22~30℃, suitable temperature for flowering and fruiting period is 15~20℃, and the fruiting rate is high at this temperature. The requirements for soil are not strict. It grows well on loam soil rich in organic matter and strong in water and soil conservation fertility. On clay soil lacking organic matter and poor ventilation, the root system develops poorly, the plant grows weakly, and the commodity is poor. The suitable soil pH value is 5.5~6.5. It is difficult to grow in the open field under high temperature and humidity in summer and autumn, and it is slow to grow in the open field in winter and spring. The tender shoots are easy to age and the commodity is poor. Therefore, in order to meet the market demand, it can be cultivated in protected fields all year round.

When we were young, we often drank cold tea for clearing away heat and detoxification. All kinds of bark or herbs were put into a pot and stewed with water. The water boiled out was dark. Among them, Dengzhancai was a very commonly used cold tea. Dengzhancai could also be cooked as a dish to eat. Although it was a little bitter, it was quite delicious, especially when there was meat in it, the soup was not left at all! Maybe we ate too little meat in those days. Thinking about it, he felt that he had been wronged. Erigeron breviscapus can be propagated by seed and plant culture. At present, the commonly used method is seedling transplanting, which is beneficial to the orderly growth of seedlings, convenient for management, high yield, saving seeds and medicines, but it costs labor.

Dogtail grass grows most in crop fields. When it was born, it was a small thin leaf or two, almost invisible from afar. However, it only needs a light rain to make it flourish. Although the roots were only floating on the ground, if they were not completely uprooted or thrown into the ground after being uprooted, they could not be killed. Only one night of dew was enough to make it sprout or revive. Its vitality was often amazing. When it grew up a little, it gave birth to a slender ear, full of thousands of seeds, fluffy swaying in the wind, like a naughty dog shaking its tail.

Generally called Setaria, perhaps we see childhood and contact with the most weeds, Setaria is also a variety of sizes and colors, but they all have a fluffy appearance. Ingenious we will also take the dog tail grass into a variety of cute little animals. Dogtail grass is a favorite plant for cattle, donkeys, horses and sheep. Old, tender, fresh or dry, it makes a good livestock feed. Autumn hay can also be used as fuel for cooking, heating and making beds. What is more artistic is that it sometimes appears in the articles of poets and writers, or in the works of painters and photographers, making such a cheap dog tail grass into a treasure with artistic vitality.
