The twenty-four solar terms are a supplementary calendar established in ancient China to guide agricultural affairs, and the naming of the twenty-four solar terms reflects the seasons, phenological phenomena, and climate change. With the arrival of each solar term, animals and plants will also undergo interesting changes with each solar term, and at the same time, the solar terms have a very important reference value for the conservation of animals and plants in our daily lives.
Today, Lu Rongjun invited experts in the green cityscape industry to do 24 solar terms related science for everyone, on the day of the sting, let us invite Zhu Jianxin, an expert of Shanghai Zoo, and the professional team of the Municipal Forestry Station to bring you the relevant knowledge of the sting festival.
Stinging is a solar term that reflects natural phenological phenomena
"Sting" refers to a decrease in temperature after entering winter
Hundreds of insects are hidden in the soil, and they do not eat or drink
After "Li Chun", spring thunder sounded
The dormant animals gradually awaken
Hence the name "sting"
It is one of the twenty-four solar terms
The stinging festival is usually in the second month of the lunar calendar
Around the fifth day of March in the Gregorian calendar
When the sting, the weather is slightly warm, the spring is continuous, the animals and plants can't help but sprout, let's walk into the park in Shanghai and feel it together!
Although many plants have just begun to sprout, on the ground, wildflowers in full bloom can already be seen everywhere, such as old crow petals, purple flower diding, Yanhuso, February orchid, etc., and blue, purple and yellow flowers dot the earth.
Old crow petals
The old crow petal is very closely related to the tulip genus, and in the past, it was also classified as a tulip genus by scholars, and the Shanghai area bloomed from February to March every year, so the old crow petal is also considered to be a native tulip variety in China.
Purple flowered ditin
Purple-flowered diding is also a common wildflower that grows in clusters on the side of the road and blooms in March to April every year, with a lilac flower.
February Blue
February orchid, also known as Zhuge Cai, is the most common wildflower in the park's green belt, often distributed in pieces, dyeing the forest under the forest into a beautiful blue-purple color.
Arab Mother-in-Law
The flowers are blue and dotted like stars on a cluster of low green leaves, and the flowers of The Arabian Motherna are long, and can be seen from February to May.
Po gai grass
The inflorescence of the bougainvillea is like a stacked pagoda, and the purple-red flowers bloom up layer by layer, which are regular visitors on the roadside and in the green belt.
Yan Husso
The flowers are purple-red, stringed, but delicate, mostly found under the woods.
dandelion
The flowers of the dandelion are yellow, like small sunflowers, and after the flowers are grateful, they quickly mature into "hairballs", waiting for the wind to come and scattering.
Of course, on the day of the sting, the peach blossoms are beginning to bloom, but don't forget that the pink peach blossoms are about to bloom.
After admiring the plants, the protagonists of the sting, the animals, appeared.
Chinese giant toad
The Chinese big toad volunteered to be the first to stand up, indeed, they had awakened as early as The Spring festival, and began to breed and lay eggs, and now on the day of the sting, there were already many toads and small tadpoles gathered by the water and grass in the pond, and then, as the temperature continued to rise, they would grow bigger and bigger, and finally become small toads to leave this quiet water.

Chinese Bee
Chinese bees are also known as oriental bees, early spring nectar and pollen are very fresh, industrious little bees are definitely not to be missed, they are busy shuttling through the flowers.

Big Red Butterfly
The Great Red Butterfly and the Yellow Hook Butterfly are native shanghainople butterflies that overwinter as adults, and after passing the cold winter, they spread their wings to bathe in the sun to warm up their bodies, and then fly to the flowers to collect honey to replenish the energy for the next generation.

Yellow hook butterflies are also basking in the sun
Oriental dish pink butterfly
Oriental butterfly is a pupa overwintering butterfly, the temperature during the sting period is enough to make them pupae, dance in the sun, not to forget to mating and laying eggs, lo and behold, this February orchid leaf on the reverse side already has their eggs.

Phylloxids
Sophora cryptoptera are also beginning to become active, farmland, wasteland, waterside are their habitat, remember that when they fly to the skin, do not shoot or pinch, but drive them away, because their bodily fluids can cause skin allergies.
Gill tortoise
Some gill turtles have also stung, flying close to the ground in the early morning, sometimes flying into the "ordinary people's homes" (indoors).

Grey snails
After the spring rains, the gray snails also began to move, dragging the big house and crawling slowly on the wet ground. Oh yes, this year is the Year of the Ox, is it also the year of the snails?
In addition to being a time for animals and plants to recover, it is also the best time for forest conservation. Many green maintenance personnel will choose to carry out maintenance work such as transplanting and pruning of trees and green plants during this period.
Transplanting
During the sting season, it is suitable for transplanting trees. The root system of newly transplanted trees is damaged and the water absorption ability is weak, and water is the key to ensuring that trees can be planted and survive, so water should be irrigated immediately after transplanting to improve soil moisture.
trim
Pruning and shaping trees in a timely manner. Remove excess shoots in the lower part of the trunk, and cut out dead branches, long branches, over-dense branches, etc.; prune the drooping branches and inner branches of the street tree to improve the height of the branches, increase the permeability, and keep the edge lines of the canopy relatively consistent.
The long branches, over-dense branches, diseased and insect branches that emerge from shrubs are lightly repaired, such as flowering shrubs such as safflower ebony, which can not only form an adjustment crown, but also promote the cultivation of flower branches and ensure the flowering effect.
weeding
During the sting period, the rain increases and the weeds are overgrown, and timely weeding measures are taken to prevent weed damage.
Overgrown
Deep ploughing and fertilization
Combined with spring weeding, shallow cultivation between rows of seedlings can not only prevent weed damage, but also improve soil permeability and enhance the rooting ability of seedlings. In addition, a focused fertilization of weaker-growing tree shrubs, flowering plants and colored leaf plants provides sufficient nutrients for the germination of new shoots of seedlings.
Prevention of pests and diseases
During the sting season, the stinging insect wakes up, which is a period of frequent pests and diseases. The prevention and control of diseases and insect pests should follow the principle of "prevention first, comprehensive prevention and control", and strictly do a good job in the observation and recording of diseases and insect pests, prevention and control and early warning.
