March 12th is the annual Arbor Day, and Mobei Senior High School in Mobei City also has corresponding plant activities.
In the early morning, the teachers and students who participated in the activity set off in a hurry.
There are vast wastelands and sandy land in Mobei. Tree planting, sand prevention and control construction, and ecological protection work are carried out all year round. Arbor Day is also paid special attention to. Therefore, there are more than 300 teachers and students in the team. Mainly the sophomores, and only a few representatives of the student union cadres for the seniors.
"Students, afforestation is related to our future. Don't just plant trees on your mobile phone, but implement it in reality. Plant trees when you have time. Plant one tree at a time, and strive to make our homes clearer and more forested. , The mountains are greener."
The students stood on this remote wasteland far away from the urban area, listening to Principal Cui's words honestly.
Li Yuhao is also listening, the second party in high school, this is the second time he has felt the fear of being dominated by Principal Cui on Arbor Day. Principal Cui is not the potbellied and annoying type, because of his good temper, he is usually welcomed by everyone, but he loves to speak the truth, and he loves to speak the truth.
After a long time, when everyone was drowsy in the early morning, Principal Cui finally finished a few manuscript pages, and started working with the teachers and students.
This wasteland is not yet a desert. There are some lonely weeds growing, but they are also getting sparser day by day. The forestry bureau staff had marked the location where the pits were to be planted, and the saplings were placed beside them. They only needed to dig out the soil with a shovel, plant the saplings in, and fill in the soil.
"Students, planting trees is planting hope, and planting trees is planting happiness." Principal Cui's middle-aged face was very serious, walking among the crowd while talking, "Planting trees is planting the future! These students, What are you waiting for? Do it!"
The people around chuckled, and it was Li Yuhao and the others who were called by the principal. They didn't want to be lazy, they just haven't started yet.
"Principal Cui, don't you think you haven't finished?" Li Yuhao said pretending to be helpless, and everyone laughed even more happily.
Principal Cui could afford this kind of joke, and passed a shovel to the kid, "It's over! Dig quickly, it's just you."
In the smiles of Wang Jiawei, He Ziyi and others, Li Yuhao held this shovel. As the flower of the motherland of the new generation, he has been well nourished since childhood. I play basketball, so I have the strength to dig the ground.
The shovel was shoveled into the mud, and Li Yuhao stepped on the head of the shovel to loosen the soil, and shouted vigorously to dig up the shovel of soil.
It took a lot of effort, but it was not difficult!
"Okay, keep digging." Principal Cui nodded with satisfaction, walked away and continued to inspect other students.
When Li Yuhao went down with the second shovel, he felt something was wrong... he felt inexplicably uncomfortable, as if there was something in the soil...
When the third shovel went down, he saw it from the mud pit at his feet, "Then, what is that... a bug?"
"Huh?" Wang Jiawei also saw it, his eyes widened suddenly, and the girl He Ziyi screamed loudly.
They saw that the loosened mud pit was full of densely packed insect egg-like things, all of which were pale yellow strips, which did not move, and were all drilled in the mud.
"What's the matter?" Teacher Liang, the head teacher, came over, and Principal Cui, who hadn't gone far, also turned around and came back. Seeing this situation, the two adults frowned. There seemed to be something wrong with this wasteland. Principal Cui said, "It seems to be locust eggs... Teacher Liang, quickly ask Captain Luo and the others to come and have a look."
Principal Cui is from Mobei. He used to do farm work and knows a little bit, but Captain Luo is from the Forestry Bureau and is more professional.
"There are a lot of things here." Principal Cui took the shovel and personally shoveled some mud lumps out, which were also full of insect eggs.
Li Yuhao and the others looked around, and more students gathered around.
Because of strong governance, locust plagues have disappeared in many places, but the ecology of Mobei is complex, and a certain amount of locusts occur every year. It can be said that locust plagues occur every year, but due to the prevention and control of multiple departments, they generally do not develop into News level.
Most of the students here have never been in contact with farmland, so they have never been in contact with locusts. At this time, they feel disgusted when they look at these eggs.
"I have trypophobia..." A girl murmured in disgust. Although she was scared, she was still watching the excitement.
"What are you afraid of?" Principal Cui said unhappily, "We used to dig it up when we were young, and then baked it, it was delicious."
There was a burst of disgust from everyone, but Li Yuhao felt a little strange, eat it? Throat swallowed...
At this time, Teacher Liang came back quickly with Captain Lin and the others, and Principal Cui stepped aside.
"Principal Cui, this is indeed a locust egg." Captain Luo recognized it at a glance, "It should be a locust with hairy feet."
"Well." Principal Cui had already checked some information with his mobile phone, and took the opportunity to educate: "Students, the ovipositor of a female locust can stretch twice as long as her body when it is stuck into the soil, and can lay 100 eggs at a time. A locust plague There are thousands of egg masses per square meter, counting 50 eggs per egg mass, and there are hundreds of thousands of insect eggs per square meter, one square meter! Let them survive the winter successfully, and it will take another two or three months It will be a big deal when it is unearthed in summer.”
Hatch hundreds of thousands of locusts per square meter? The students were all stunned.
"The situation is not that serious." Captain Luo smiled with a simple and dark face, "Not every egg can become an adult, and usually there are not so many eggs. The population density of this kind of hairy-legged locust has been lower in recent years. On average, there are 30 adult insects per square meter, and 100 adults per square meter is a lot.”
"Yes, yes." Principal Cui nodded humbly, "Students, do you hear that locusts and a plague of locusts are two different things."
"However, if the locusts occur in a large area and there is no control, the low population density will also cause disasters." Captain Luo said again, as if talking about cross talk with Principal Cui, making the students laugh, "The locusts in Mobei City every year The area where the occurrence occurred is several million mu in and around the farmland."
But this piece of wasteland was fine a few years ago. Captain Luo and the others dug some holes in the surrounding soil with a shovel to check, but fortunately there were no eggs.
It seems that Li Yuhao won the lottery with one shovel, and the insect eggs were concentrated in the ten square meters, which is a small area. However, because of this incident, the tree planting activity was temporarily suspended. Captain Luo and the others needed to call someone from the Agriculture Bureau to come over to do inspections, apply pesticides, etc., and do a good job of prevention and control.
"Captain Luo!" Li Yuhao chased after him, and asked a doubt in his heart: "How deep can insect eggs be hidden in the soil?"
"It's just on the shallow surface, less than half a meter." Captain Luo said, he was very kind to studious students.
"Oh..." After hearing this, Li Yuhao still felt a strange feeling. The more he looked at the mud clods where the eggs had been dug out, the more so.
Looking around, there is a barren land... Could there be a deeper location
And that feeling of longing became even stronger, which made Li Yuhao swallow again.
