Xu Zhan and Chi Zhanzhan exchanged looks.
Xu Zhan said, "Can you show it to me?"
Miss Tu took it off and handed it to him.
Xu Zhan couldn't understand why, and muttered: "What's so great about a loudspeaker? Other factories also produce it."
Just not so small.
Miss Tu pursed her lips and smiled: "Yes, but our product uses mobile phone batteries. It can be used for a long time on a single charge, up to eight hours. It also solves the environmental pollution problem of traditional dry batteries."
Xu Zhan was embarrassed and was hit in a sore spot again.
Although Miss Tu said it very tactfully, he still heard the irony in it, because only "Wenjun Industrial" can produce mobile phone batteries.
Amplifiers produced by other manufacturers all use dry batteries. The batteries need to be replaced in half an hour at most, and they are also very heavy.
The technological advancements of this amplifier certainly don’t end there.
There is a lot of mystery in the headset that can be bent at will.
But it couldn't be seen without taking it apart. Xu Zhan turned the loudspeaker over and over, trying to open it.
But Miss Tu had already extended her hand, so he could only return the loudspeaker to her.
Ms. Tu put on the loudspeaker again and said, "Everyone, please come with me. I want to finish the tour in one morning, and my schedule is very tight."
Chi Zhanwang frowned and asked, "Since I finished watching it in the morning, why don't we continue in the afternoon?"
Miss Tu pursed her lips and smiled: "You have to check out of the hotel before twelve noon. If you want to visit in the afternoon, you have to apply for an extension at noon and take a rest. We will come back in the afternoon."
Everyone's heart was racing when they heard this: Li Wenjun is really evil. This means that he has to pay a few hundred yuan per person to visit in the afternoon, otherwise he has to leave.
Haha, but you don’t need to look at this thing all day long.
Miss Tu didn't seem to see the anger flashing in everyone's eyes, and still smiled and said: "Everyone, please go this way, this is our rice field area. I think everyone has felt the feeling of living under the rice fields and fruit trees last night. The benefits.”
Some people involuntarily touched the pimples on their faces or licked the blisters in their mouths.
"Hiss", you are still so greedy and greedy for petty gains even at your age, and you are really being punished...
Someone else asked: "Does the same kind of rice grow in such a large rice field area?"
Ms. Tu: "No, we cooperate with the Hunan Academy of Agricultural Sciences and grow several types of rice every year to compare their advantages and disadvantages."
The person from the Northeast rice-producing area said: "Oh, by the way, no matter what kind of rice it is, pests and diseases are inevitable. So I want to ask, what kind of insecticides do you use for this rice? And weeding, how can you get rid of it without herbicides? ?”
I heard that there was a locust plague in the neighboring county not long ago.
Ms. Tu said: "We all use biological and mechanical methods to remove insects and weeds."
The man said reluctantly: "What kind of creature is killing insects?"
Just as he finished speaking, there was a loud voice behind him.
Xu Zhan and the others turned around and saw the group of ducks coming yesterday.
The ducks covered the road they came from, flying and running, and rushed into the rice fields.
A full ten minutes have passed and it's still not over.
Now the late rice has been harvested long ago, so only rice stubble and grass are left in the rice fields.
These grasses are neat and tidy, and they don't look like weeds at all.
And it's late autumn now, and the grass is still green.
Looking around, it doesn't look like rice fields, but like endless grasslands.
Those ducks ran into the field and pushed forward like a weeder. After a while, only the roots of the weeds were left, and the grass seeds on the ground were pecked clean. Insects and other things are basically impossible to escape.
Miss Tu said: "There is not enough wild grass to eat, so after we harvest the autumn grain, we have to plant some grass for the ducks to eat."
Improve the soil and turn it over in the spring to make compost.
The man said unwillingly: "There are no seedlings now, and the ducks won't eat them. I don't believe they won't eat them after the rice seedlings are planted in spring."
Miss Tu said: "Our ducks are so good, they don't eat the grass seedlings. Duck manure can also fertilize the grass seedlings."
The man shook his head: "Impossible. You are a myth."
Miss Tu smiled and explained: "Because ducks are omnivores and prefer to eat insects and small creatures in the water. And plowing the field in advance is equivalent to removing the grass in advance. When the rice seedlings are transplanted, the seedlings have grown very long, and the grass They grow later than grass seedlings and are more tender. So even if ducks want to be vegetarian, they will only eat grass. Wenjun Agriculture has several poultry farms, and there are only two or three ducks raised. They just raise different species. Ducks. Ducks from different farms will rotate to different fields and vegetable fields to weed, hoping that ducks with different flavors can weed all the grass with different flavors."
Although it sounds a bit unbelievable, it is not completely impossible.
So when there was a locust plague last time, why didn’t Li Wenjun and others respond?
It's because that little locust is not enough for all the ducks to eat.
The man pursed his lips and said, "Even if there are insect pests, there are also various diseases such as rice sheath blight, rice blast, bacterial blight, and bakanae. I don't believe it. Your rice is so lucky not to get sick all year round?" If you get sick, will you get better without taking medicine?!"
Not to mention being sick, even if it's just a bug, some bugs won't even be eaten by ducks.
Miss Tu said: "This gentleman is indeed an expert and has a comprehensive understanding of rice diseases. However, we have also taken preventive measures. The diseases you just mentioned can be prevented when cultivating seeds. .”
The man was stunned: "How to prevent it."
Ms. Tu: "The process is very complicated. It is the result of many years of cooperation between our research institute and the Agricultural University and the Academy of Agricultural Sciences. If you want to know more about it, you can sign up for one of our agricultural training courses."
The man almost cursed: Damn it, you still need to sign up for an agricultural training class? You are trying to pluck the wool until it becomes bald.
Some people actually asked: "How much does an agricultural training class cost and how long does it last?"
Ms. Tu: "There are long-term ones. There are short-term ones. The tuition fees range from tens of thousands to several thousand. If you are interested, you can go to our university for consultation."
Everyone pursed their lips: Li Wenjun, you are really kind.
Obviously we can grab it directly, but we still have to send us to school for a few days.
Xu Zhan said hurriedly: "There is no rice in the fields right now, and there is nothing to see. Let's go to the next place quickly."
Chi Zhanwang: "What is the next base and how far away is it?"
Ms. Tu: "The blueberry plantation. It's not far, just walk 1.5 kilometers."
Someone pointed to a special-looking plant beside the road and asked, "What is this? Did you plant it too?"
Ms. Tu: "This is rue. You may have come from the north of the Yangtze River, so you haven't seen it before. This plant is very common in the wild south of the Yangtze River. North of the Yangtze River, it can only be cultivated in greenhouses and greenhouses."
The man asked again: "What does this do?"
