After each harvest of farmland, the soil needs to be insecticidal, sterilized and weeded to ensure the growth of the next round of crops, and now most farmlands in the world use a variety of chemical pesticides to achieve this purpose, however, long-term use and exposure to chemical pesticides will bring acute and chronic poisoning, resulting in decreased human immunity, teratogenicity, neurological disorders and other hazards.

Some pesticides are easy to remain on the surface of vegetables and fruits, which is not easy to remove, which has a great impact on food safety in people's daily life.

At present, all countries are committed to researching new green and environmentally friendly "pesticides", carrying out biological control and physical control, and seeking the road of long-term development of farmland and the road of food safety of vegetables and fruits.

Learning from the appearance of the farmer uncle who was sent to guide, the scattered corn stalks were inserted into the soil obliquely, and the two crossed and the ground formed an angle of about 20 degrees, so that a certain gap was formed between the ground and the straw, which was conducive to full combustion and accelerated the burning speed of the straw.

Before lighting the straw, you need to observe the wind direction to ensure that the wind does not spread to other places.

Soon, the yellow stalks, which had been largely hollowed out by the ripe corn, were burning, and after the farmer brought the players to a safe distance, he went around the fire a few times from a distance.

Soon, the corn stalks were burned to ashes, and the fire was gradually extinguished without the support of combustibles, leaving a blank field of black ash.

"Come on a few boys, come and push some fat with me." The uncle with a strong voice greeted.

The male players almost all gathered around.

Looking at the young men standing in front of him, the uncle couldn't help but be happy.

"It's also positive. You, you, and you...... The six of you will come with me, and the rest will wait here. He called out a few male players who were very powerful at first glance and led them away.

Among the people who were taken away, there were Zhou Hao, Dong Mingzhe, Peng Lei, Huang Dake and a new player that Tang Qinqin didn't know.

These people are big, and in the eyes of the uncle, they have inexhaustible strength.

Song Yuanze walked over with long legs, nodded to Mengru and Lan Lan as a greeting, and then stood beside Tang Qinqin and held her hand.

This is the first time that the two of them have been so "intimate" in front of everyone since they confirmed their relationship, and it can be regarded as an official announcement of their relationship.

Mengru and Lan Lan, who already knew the situation from Tang Qinqin, were quite calm, and Yang Qing and Tao Tingting completely lost their expression management, holding their faces and staring at each other.

Tang Qinqin was embarrassed to withdraw his hand, but he was held tighter.

But other than that, there were no other intimate actions, and Tang Qinqin could only pretend to ignore it.

Soon, the people who left came back one after another.

Each of them pushed a small cart, connected with seven uncles, five people pushed "farmhouse fertilizer", and two people pushed fertilizer.

This farmhouse fertilizer is the reincarnation of chickens, ducks, geese, pigs, cattle and human grains produced by eating grains, which is simply a variety of poop.

Mix the cooled straw ash with fertilizer and farmhouse fertilizer, mix it into the soil, increase fertilizer, supplement nutrients, sterilize, kill insects, and wait for a few days to loosen the soil and sow seeds again.

In the face of the stinking farmhouse fertilizer, the boys took the initiative to take over the task of mixing the fertilizer, but the female players adapted well, although some people were smoked and wanted to vomit frequently, but no one flinched.

Players from the countryside have no shadow of this, and they follow the uncle to learn quickly, although Tang Qinqin has basically never done farm work, but he does not react much to the common taste in this village, and adapts well.

["In the past, there were madmen, and there were immortals. The pen fell into a storm, and the poem became a weeping ghost and god. "May I ask who this verse is commemorating? ]

"Li Bai." This is a five-character ancient poem written by Du Fu for Li Bai in the Tang Dynasty, "Sending Li Twelve Bai and Twenty Rhymes", with a total of 20 sentences.

["There is no way out of the mountains and rivers, and the willows and flowers are bright and another village."] Whose verses are they? ]

"Song Dynasty poet Lu You."

["There will be a time when the wind and waves will be long, and the clouds will sail into the sea."] Who is the poem and the title of the work? ]

"The Road is Difficult to Walk by Li Bai in the Tang Dynasty."

["How can we solve our worries? Only Du Kang. Qingqing Zijin, leisurely my heart. "Where is this poem from? ]

"Cao Cao's "Short Song Xing" in the late Eastern Han Dynasty."

Tang Qinqin was answering the question independently at this time, and the category he chose this time was ancient poetry.

["Zhumen's wine and meat stink, and there are frozen bones on the road."] Which famous poet of the Tang Dynasty came from? ]

"Du Fu." This is a poet who has great love and worries about the country and the people.

["Ask the world, what is love, and teach life and death."] Whose phrase is it? ]

"......" Actually, Tang Qinqin does not agree with the words of life and death for the sake of love and love, in this life, love is not a necessity, there is better, there is no way to be alive, because in addition to love, we also have family affection, friendship, life is only once, some people want to live but have no chance, some people are trying to find death and life.

However, in this world, except for life and death, it is all trivial.

"On the occasion of Jin and Yuan, the writer Yuan Hao asked "Touching the Fish, Yanqiu Ci".

["Shi'er" is a posthumous poem written by a patriotic poet of the Southern Song Dynasty to his son on his deathbed, may I ask who he is?"] ]

"Lu You."

["The moon is born on the sea, and the end of the world is at this time."] Who is the author? ]

"Zhang Jiuling in the Tang Dynasty."

After answering the question this time, Tang Qinqin gained 1,500 points, and the points exceeded the 50,000 mark for the first time.

Doubling it again can exchange Xiao Qi for a primary entity, however, neither she nor its pursuit is more than that.

After finishing the "Ancient Poems" answer, Tang Qinqin looked at the information on the character panel and found that all the items he got had been used, except for the "magic eraser" that had been dusted for a long time.

"Xiao Qi," Tang Qinqin had nothing to do but ascend to the Three Treasures Palace, "What can this eraser be used for?" ”

Its instructions for use state that it can correct any textual errors and restore the truth that has been tampered with. However, in reality, Tang Qinqin did not encounter a place where it needed to be used.

"Wait a minute, I'll check."

Xiao Qi, who was finally remembered, burst into tears, and searched for information in a sluggish manner.

"Qinqin, to use this eraser, you need to enter a special game, which is a bit difficult."

"Is the game mode single-player or multiplayer?"

"It's multiplayer."

"Let me be sure, is it a good reward?"

"That's right!" Xiao Qi rolled his eyes speechlessly. Even if there is no actual body now, it has learned all kinds of human expressions as a string of virtual code.

In their code chat group, all kinds of human emojis are particularly popular, and they also especially like the human world's dance, gymnastics and other forms of physical exercises, and every movement in the "broadcast gymnastics" is familiar to them.

"Okay, then take this task, Xiao Qi."

Tang Qinqin happened to be relatively free recently.

When I come back after the eleventh, I will be busy again, busy preparing for the exam, busy with the New Year, and earn more points and vouchers when I have time.
