Everyone was planting rice and chatting, Liang Yu and the others were all taking advantage of the freshness, so they didn't feel very hard. Now there are fewer paddy fields, and if you catch up with all the paddy fields and work for four or five days in a row, as in the past, people will be very tired.

"Hey! Take a look! What did you kid do? None of them are presentable? You look at someone else's. Chu Jiaqiang saw that Chen Wu was crooked, and he couldn't do it, he couldn't stand it upright, and it was uneven, one tall and one low, so he immediately criticized.

Everyone looked up and was immediately happy. That guy really didn't make a good appearance, and everyone already took good care of him, leaving only four places for him. Just plug four plants evenly into each row and you're good to go. It's just that it's still extremely messy.

"Ahem! I don't know how to get it, I always can't get it right. Chen Wu was also a little embarrassed. Originally, I thought this thing was very easy. But when I really got started, I found that it was not so simple.

"Khan! Forget it, you guy go pick seedlings! "Chu Jiaqiang began to drive people away, but it was true that this guy really had no talent.

Chen Wu smiled, walked up to the ridge, and then walked towards the seedling field with a dung basket. These princesses, who used to be pampered, are now working in the farmland. If they were seen by their best friend, it would be incredible.

Chu Jiaqiang hurriedly made up for Chen Wu's loss, his movements were the fastest, and the area of rice planting was also the largest. Everyone deliberately avoided this demon, and doing farm work was simply the number one.

You say he's lazy! When it comes to the real work, almost no one can match him, not only fast, but also done perfectly, almost without fussiness. You say he's diligent! Usually it's like a snail, you have to poke him with a stick in the back before he moves.

Wait for Chen Wu to come over again. When everyone saw that scene, they were speechless.

I saw a giant bear carrying two loads of seedlings on his shoulders, and this time, it was definitely enough for you to plant for a long time. Needless to say, Chen Wu's guy must have given a lot of food to those two bears. Otherwise. They won't be as positive. Do the work for you.

Speaking of the two bears, even Dean Ding of the research institute was quite helpless. Some time ago, those two guys went to a construction site in the village to beg for food. The fifth uncle and the others saw that the two bears were guarding beside them, so they had to order everyone to cook some meat for them to eat.

Who knows. This one is addictive. Lying in the construction site every day, in order to eat, he also helped carry bricks, and everyone was dumbfounded. This matter is also in the news. It made the village full of turmoil.

In the past two days, everyone began to be busy with the farm, and the things on the construction site were temporarily stopped, and the two bears settled down.

"You kid, aren't you afraid that Professor Wen will scold you?" Chu Jiaqiang immediately said to Chen Wu.

Chen Wu immediately said innocently: "You can't say that, it's better to let them do some work than for them to go to the village all day long to thank them for their sneaky deeds, right?" ”

As soon as these words came out, Chu Jiaqiang and the others immediately had nothing to say. It's not unreasonable, those two guys. Walking around the village every day, as long as the villagers don't pay attention, the kitchen cabinet at home may be emptied.

For this matter, Chu Jiaqiang had already warned the two bears very seriously. But those two guys were already invincible, and they didn't have the slightest intention of repenting. When you are hungry, you will find a way, almost by all means, by any means!

In the words of those tourists, two big stomachs, in order to eat together. It's not easy. That's exactly what they do. Everyone was selectively silent.

"Third child, there is a locust on your foot." Chu Jiaqiang turned his head and suddenly found that there was a locust sticking to Zhou Furong's stomach, which was what others called a leech.

Grasshoppers contain hirudin, which can delay and hinder blood clotting, thus having anticoagulant effects. Like the leeches on the mountain, they specialize in sucking blood. Wounds bitten by them are generally difficult to heal because they contain hirudin, which makes your blood can't clot and keeps flowing like this.

Zhou Furong was startled, hurriedly checked, and suddenly turned pale with fright. This thing is the most terrifying thing for him, it feels even more terrifying than a snake, a typical vampire.

"Boss, hurry up and help me catch it. How can there be these things here, I'll go pick seedlings too! Zhou Furong looked around a few times and found two more, swimming around in the water.

The leech is a semi-parasitic animal, which requires that its movement mode should be adapted to its lifestyle. The movement of leeches can be divided into three ways: swimming, inchworm movement and wriggling.

When swimming, the dorsal and abdominal muscles contract, the ring muscles relax, and the body is laid flat like a willow leaf, moving forward in waves. The latter two types of movement are usually used by leeches when they leave the water body and when they are used by leeches, and they are used alternately with front and rear suction cups. However, the former is a movement like an inchworm: the front suction cup is first fixed, and the rear suction cup is released, so that it advances alternately and travels faster.

The difference between peristaltic and inchworm movement is that peristaltic makes the body lay flat on the object, and when the front suction cup is fixed, the rear suction cup is released and the body stretches forward along the plane. This type of movement is slower, but it can walk through the soil or through the space between a person's clothing and skin to suck blood.

Chu Jiaqiang sweated wildly, this guy was not even afraid of snakes, he was actually afraid of this kind of thing. Not only Zhou Furong, but those girls also felt goosebumps when they saw it, and their hearts were furious.

In the countryside, bold children will catch leeches and turn them over with straw poles, and die after a period of drying. It is said that adults say that the vitality of the leech is very strong, and if it is not turned over, it is cut into sections, and when it sees water, each section of it can become a new leech. Of course, this is not scientific.

"It's disgusting." Xu Bimei said.

Chu Jiaqiang smiled faintly, he knew that the grasshopper was still a traditional Chinese medicine, and it was a traditional special medicinal aquatic animal in my country. After the dried products are processed into traditional Chinese medicine, they have the effect of treating stroke, hypertension, stasis, amenorrhea, bruises, etc.

Therefore, there are people outside who specialize in raising this kind of thing, and I heard that it is quite valuable.

Many countries in the world have used the blood-sucking habit of leeches to bleed patients in ancient times, especially in Europe. In many places, leeches are collected and even cultivated artificially in pools. The use of leeches in China was even earlier, and it is recorded in ancient books that hungry leeches were packed into bamboo tubes and buckled on washed skin to suck blood and cure red and white swelling. But it's more important to put leeches into medicine.

Because blood-sucking leeches often attack humans and animals, the distribution of leeches brings many inconveniences to tourism, grazing, scientific investigation and forest management. Nevertheless, it has important medical significance because the salivary glands of leeches are able to secrete vermicin, which prevents blood clotting.

With the improvement of people's living standards, the change of food structure, and the increase of China's elderly population, the demand for antithrombotic drugs is increasing day by day. Therefore, it is of great significance to reasonably protect, develop and utilize this animal resource and turn harm into advantage, which is of great significance for promoting economic development and treating thrombotic and other diseases.
