Chen Kang took out two small white wine glasses from the drawer and raised the wine bottle to Chen Cheng.

"Would you like a bite?"

Chen Cheng chewed the rice in his mouth and refused him with his head.

If a father begins to persuade his son to drink in person, it means that in his eyes, his son has grown up and can treat him with the etiquette of an adult man.

And the son generally doesn't like to drink with Lao Tzu, because the man likes to climb the brother when he is drunk. If this happened to the father and son, everyone would feel embarrassed when they woke up.

"Son, how are you going to use what method to solve the brown streak disease of the lotus root in the field?"

Chen Kang took a sip of the liquor and asked with a frown.

"I'll go to the fields after I've eaten. However, from the cursory observation just now, I am afraid that this is difficult. ”

Chen Cheng sucked a piece of pig's foot and said vaguely.

The main thing is that the food cooked by my mother is so fragrant that he is simply gobbling it up.

"You too, can you wait for your son to finish eating?"

"Wasn't I in a hurry?" Chen Kang argued.

"What could be more anxious than a son's meal?"

Xu Guihua said, giving Chen Kang a 'no further refutation' look, and Chen Kang silently thought to himself.

In many rural families in the Hanxi region, the words spoken by housewives are very effective, and men are mostly called "rake ears".

Chen Cheng eats by himself, ignoring his parents' daily bickering to show affection.

Chen Cheng had almost finished eating, and Chen Kang finished drinking and was ready to eat. Xu Guihua cleaned up her and Chen Cheng's dishes and chopsticks while intimidating him.

"Hurry up and eat, you eat the slowest every time. I'll finish washing the dishes later, and you'll do your own laundry! ”

Chen Kang didn't answer, and still ate leisurely.

This is the old husband and wife, and it is fun to talk about it every day.

After a while, the courtyard door of their house was suddenly pushed open.

"Brother Chen Kang, hurry up to the village after eating!" It was the village chief Chen Shou who shouted.

Most villages in the country were originally inhabited by families, so most people in a village have the same surname.

"What are you going to do?"

Chen Kang was also unhappy with his denial of Chen Cheng last night, so he didn't directly agree to him.

"Technician Zhang came back from the county, brought back the pesticides for the lotus root field, hurry up and listen to the spraying skills taught by Technician Zhang, each household has to divide pesticides according to the amount, there will be no if it is late!"

Chen Shou finished speaking and left.

He is the head of the village, and no matter how small the bean bag is, it is also dry food. In his view, a notice is a notice, and the villagers are not allowed to question too much.

Chen Kang finished the meal angrily, put the bowl on the table, and said to Chen Cheng: "Let's go, go to our field to see the lotus roots." ”

Chen Cheng asked, "Don't you go to the village?" ”

Chen Kang said: "That technician Zhang has been working for more than a month, and the pesticide has been sprayed several times without any effect, and this time it is probably in vain." ”

Chen Cheng nodded and followed Chen Kang out.

The field was planted by his father, and his parents were also his father, so he had to listen to his father's decision.

Walking to the edge of his lotus root field, Chen Cheng looked at the next few acres of fields, and they were all in a ruined scene.

At this time, it should still be a dark green lotus root field, but now it is full of dead branches and rotten leaves.

Chen Cheng walked to the edge of the field, took off his shoes and socks, pulled up his trousers and walked down.

These leaves have fallen off into the water due to the decay of the meridians, leaving only bare petioles, and some floating leaves have rotted and emitted a foul smell.

There are also some milder ones, with a few green leaves on top, which look very eye-catching in the gray lotus leaves.

It stands to reason that these lotus leaves that have already developed the disease should be cleaned out in time, but because there is too much area, the farmers are simply too busy.

What Chen Cheng learned from the system is that the brown streak disease of lotus root is a bacterial disease and is extremely contagious.

The brown streak fungus survives on diseased residues or collects lotus root plants for overwintering with mycelium and conidia clusters, and produces conidia the following year. The conidia were initially infected with the help of wind and rain propagation, and after 2~3 days of latent incubation, the diseased department produced conidia and re-infection.

In spring and autumn, brown streak disease is highly precise, especially after a storm or when the lotus root grows weakly.

Once a surviving brown streak bacteria appear in one place, tiny mycelium and conidia can quickly spread to the surrounding fields through wind or water.

Generally speaking, if brown streak disease occurs in the lotus root field, it is necessary to clean up the diseased lotus leaves in time, and use deep burial or incineration, lime burial and other treatment methods to effectively extinguish the germs.

Moreover, when removing the diseased leaves, it is necessary to keep the petiole of the lotus leaf, because the water in the field also contains germs at this time, and the petiole and stem of the lotus leaf are hollow, and the slightest carelessness of the germ can use it as a channel to infect the underground lotus root.

Once the lotus root is parasitic with germs, it will be transmitted to the next generation when it is used as a seed for the next year.

It can be seen that the contagiousness of the brown streak bacteria is very strong.

This is also the reason why brown streak disease can quickly spread to the lotus root fields of the entire Xiting County.

Chen Cheng picked up a lotus leaf with several brown streaks on the surface, and when he turned it over, the back of the lotus leaf was even more serious, and the meridians had completely turned brownish-gray.

One by one, the round spots gradually joined together, and the most serious places seemed to have been burned by fire.

Brown streak lesions begin as pinhead-sized yellowish-brown dots, and then gradually expand into rounded to irregularly shaped yellowish mabrass or brown dead spots, especially on the dorsal surface of the leaves.

After the fusion of multiple lesions, large scorched spots appear on the leaves, and in severe cases, in addition to the leaf veins, the whole leaf is covered with lesions, causing half or the whole leaf to dry up.

In fact, brown streak disease only harms lotus leaves, does not affect the taste of lotus root itself, and is also harmless to the body.

However, as we all know, plant leaves are important living organs and play an important role in providing nutrients to plants.

If the leaves are sick, the growth of the plant will definitely be affected.

The current situation is that the lotus root has already blossomed and set seeds, waiting for all the nutrients to gather into the lotus root in the soil. But suddenly the leaves can't produce nutrients, which will definitely affect this year's lotus root production.

Chen Cheng leaned the blade into front of his eyes, and the system's prompt sounded.

[Winter lotus root varieties are detected, and the yield is expected to be reduced by more than 50% during the severe period of brown streak, please deal with it as soon as possible! ] 】

The system, which has always been indifferent, has sent a signal of "dealing with it as soon as possible" this time, and it seems that the growth of lotus roots in Xiting County this year is indeed worrying.

Chen Cheng turned his head and asked, "Dad, under normal circumstances, how many catties of lotus root do we produce per mu?" ”

"About 4,000 pounds! Because we have to take care of tourism and appreciation, we plant lotus root varieties that are only harvested once, not in summer, but only once in winter. ”

Chen Cheng nodded.

Some lotus root fields that are only used to produce lotus roots can be harvested three times a year, and the total yield can reach 6,000 catties per mu.

Their family's yield of 3,000 catties per mu is not very prominent, and the yield level is above average.

"How much is the purchase price of a vegetable merchant?"

"A piece of seven cents."

Chen Cheng calculated slightly in his heart that if the yield was really reduced by 50%, one mu of land would lose 2,500 yuan, and their family would lose more than 10,000 yuan for 6 acres of land!

If the entire Xiting County is calculated, it is estimated that the loss will exceed 10 million!

As he spoke, a large group of people walked from the entrance of the village to the lotus root field.
