"I will increase capital investment! Tell you what, Mr. Xu, you will be an academician of the Academy of Sciences, which means you will be an official of the Academy of Sciences. In the future, you will concentrate on studying this helicopter in the Academy of Sciences. You must make it fly higher and farther, and it is best to be controlled by people! I can give you a seal on the helicopter! "
Xu Zheng couldn’t help but feel grateful. "It’s hard to repay you even if you die!"
Ran Min nodded. "You should report to Jabba first. There are many skilled craftsmen in the Academy of Sciences. These people are as ingenious and quick-witted as you. If you work together to develop this kind of helicopter, I believe that it can be operated by people, but it can soar freely in the sky. The helicopter will definitely appear!"
"promise!"
Wait until Xu Zheng GeHong some puzzled tunnel "positions this pile of broken wood even if can fly again? So much attention? "
"Ha ha GeAiQing you don’t dismiss this pile of broken wood in the future if the helicopter is really Xu Zheng they just came out, but it is great for the military and disaster relief! Not to mention that without this helicopter, our army can throw arrows, rain, roll logs and attack the city with sulfuric acid, and our resistance will be greatly reduced! "

Chapter 475 The locust plague
It’s time to get up. "
Ran Min shared a bed with Queen Dong. When she saw that she was still lying motionless in bed, she was in distress situation like a dead pig, and she pushed him on the shoulder.
But Ran Min mumbled two bleary-eyed glances at a Dong Qiaoqiao but did not move.
Dong Qiaoqiao called several times and Ran Min finally got up reluctantly.
The first step in getting up is to brush your teeth and wash your face.
Ran Min has already sent out toothbrushes and toothpaste. If toothbrushes are easy to make toothpaste, just give them to the doctors and alchemists. These people are knowledgeable and ingenious, and they can be called contemporary chemists!
Isn’t it easy to make toothbrushes and toothpaste with Ran Min’s advice?
In fact, before there was a toothbrush, the ancient methods of tooth protection and cleaning were knocking teeth and gargling. In ancient times, gargling generally used mouthwash with concentrated salt, strong tea and wine.
Even if you protect your teeth in this way, the ancients suffered from dental diseases because of the poor cleaning effect.
The ancients used to make willow branches brush their teeth, and the ancient medical skill "The Secret of Outer Taiwan" said that Yang branches could make their teeth "fragrant and smooth" by dipping one end in medicine.
In addition to poplar branches, people also look for other suitable dental cleaning materials according to local conditions, such as Sophora branches, peach branches, kudzu vine, etc., which have the same bitter, astringent, pungent and spicy taste as poplar branches, and they "chew" to clean their teeth.
Dai Li Shizhen also said that tender willow branches are "wonderful to cut teeth and clean teeth."
I washed my face and wore a crown, and Ran Min followed suit.
"Recently, serious locust plagues broke out in most areas of Lean, Jinan and Beihai counties in Qingzhou. As many as 100,000 people were affected by locusts. The locusts crossed the border and ate the grains of sorghum, wheat, grain and other agricultural products in the field to collect the surplus grain of the family! I ask the people of Le ‘an, Jinan and Beihai to reduce their taxes for one year! "
Shang ordered Cui Hao to play for the first time
Smell speech Ran Min eyebrows a wrinkly.
This Qingzhou is really troubled!
Throughout the agricultural history of China, water, drought and locust have always been regarded as the three major natural disasters, which directly endanger agricultural facilities because of the outbreak of locust plague, causing even greater losses to agricultural production and even affecting the economic development and political stability of a dynasty
This Qingzhou has been a disaster-prone area since ancient times, with droughts, floods and locusts. It’s really incurable!
Let’s talk about floods. There is a Yellow River in Qingzhou. In summer, the water volume has soared and floods are inevitable. However, Ran Min can prevent floods by repairing river banks.
What about drought?
Drought is inevitable. After all, if God doesn’t give us a hand, the imperial court must release grain as soon as possible to help the victims. Otherwise, if it is late, the people will be cornered and the people will probably rise up!
What about this locust plague?
The plague of locusts seems to be the solution. Since ancient times, the imperial courts have sent people to help the victims immediately when locusts occurred!
Once the three disasters, flood, drought and locust plague, break out, if the imperial court does not pay attention to the relief of the victims, it is very likely that the regime will change!
There is no way since Chen Sheng and Wu Guang killed thousands of knives in Daze Township after the uprising, people believed that "princes would rather have seeds"! It’s really cornered everyone, and the people will definitely rise up and resist.
Ran Min frowned and said, "Except Qingzhou, which is plagued by locusts, it is not a problem for three counties to pay taxes for one year. Now the people have surplus grain in their homes to spend a year and a half, and the government can borrow it, but we can’t rush to get rid of taxes every time a locust plague occurs. The treasury needs income and the people can’t do nothing."
"Zhu Qing, please think about it, such as managing this locust disaster!"
Smell speech ministers are whispering.
"This ….." Cui Hao a face of embarrassment tunnel "pursuit I really don’t know should be like locust control"
"Cui Lingjun, have you ever studied in Youzhou? Have you ever noticed what locusts like and don’t like?"
Hearing this, Cui Hao thought for a moment and said, "Grasshoppers generally eat wheat, sorghum, rice and grain, but they can eat all agricultural products, but they don’t eat soybeans, alfalfa and fruit trees."
"Well, this is also a way to reduce the food source of locusts!"
Ran Min nodded slightly. "Many kinds of locusts eat corn, wheat, sorghum, rice, grain, etc. instead of soybeans, alfalfa, fruit trees, etc. Therefore, planting as many soybeans, alfalfa, fruit trees and other trees as possible in the locust occurrence area can prevent locusts! Just follow this law and order to plant these trees as much as possible in locust-prone areas. "
"obey orders"
At this time, Shang Wei, the punishment department, stepped out and said, "There is a law for courtiers!"
"Go ahead."
"We can reduce the locust habitat"
"Some locusts occur in low-lying areas. We can transform such plots into pond culture and raise shrimps, which can greatly reduce the locust habitats and better control locusts!"
"Yes, this method can also be popularized, but the cost is a little high." Ran Min shook his head. "Let the local government pay for the renovation of the pond and earn rent through concession."
"Sage!" The ministers call way
In fact, Ran Min also knows other methods, such as biological control
Many natural enemies of grasshoppers include frogs, lizards, birds, fungi, viruses, nematodes, predatory beetles, parasitic bees, parasitic flies and so on.
Many kinds of frogs or toads can eat locusts, such as ze frog, golden frog, wood frog, black-spotted frog, black-eyed toad, middle-flowered toad and so on.
Rana nigromaculata can prey on locust 135 every day.
