Chapter 752
The problem of pesticide residues in fruits and vegetables, as well as food safety issues in Longguo, has reached a very serious point, and changes are urgently needed! Especially in recent years, due to the ban on burning straw, the number of underground pests has skyrocketed! Dig up the soil full of straw and take a closer look. It is full of insect eggs. Because the straw fragments rotting in the soil are simply the most ideal breeding place for insect eggs. Those insect eggs are even more disgusting than the maggots in the rural dry toilets, and they specifically bite the roots of crops. In this case, the effect of simply spraying pesticides from the ground is getting worse and worse. What should we do? Flood the pesticides! Anyone who has grown greenhouse vegetables knows what a stuffy greenhouse is!
In the vegetable greenhouse production areas across the country, almost every household is stuffing the greenhouse as long as it is July in summer!
What is a stuffy greenhouse?
It is when the temperature is high in summer.
Pour water and pesticides on the surface of the soil, and then cover it with a layer of plastic film.
In the airtight and high temperature, the surface soil above seven centimeters can reach 50-70 degrees!
In this case, even if the stuffy and killing lasts for 25-30 days, only most of the pathogenic bacteria and nematodes can be killed.
Want to kill them completely?
It is basically impossible!
Because the stuffy greenhouse technology can only suffocate the soil layer above seven centimeters.
The temperature of the soil below seven centimeters will drop sharply from 70 degrees to about 40 degrees.
This temperature is very comfortable for insect eggs.
It can be seen how difficult it is to kill underground insects!
So how did the ancients kill underground insect eggs?
Nothing else… slash-and-burn farming!
1: The flame can completely burn all pests and insect eggs. No insect eggs can withstand the high temperature of more than 1,000 degrees. Its effect is many times that of a stuffy shed!
2: Under the burning of the flame, all grass seeds on the surface will be burned into ash, and there will be much less weeds next year.
3: The ash after the burning of straw contains almost all the nutrients and trace elements needed by plants, and can also effectively prevent the soil from compacting.
There must be a reason why slash-and-burn farming has been passed down for thousands of years.
You must know that in the past, crop straw had great utilization value for farmers.
In ancient times, there was neither natural gas nor electric kettles. Which of the fires and cooking did not require fuel?
Were the ancients all fools? They would rather run up the mountain to chop wood than tie up the straw and cook at home?
If the land did not need slash-and-burn farming, would the ancients be so stupid as to burn the good fuel in the field for nothing?
Therefore…
Today’s pest problems are much more serious than before!
With more pests and diseases, we naturally have to double the amount of pesticides sprayed.
If too much pesticide is used, it will naturally cause health problems when eaten, leading to more and more strange diseases.
As for why slash-and-burn farming has not been restored until now? Food safety issues have not been effectively solved?
The problems here are too complicated, and they will also touch the interests of too many people.
At least with Su Mo’s current pattern and vision, it can be clearly known.
Once the laser insect killer is developed, even with his current status.
If you want to promote it comprehensively, you will inevitably encounter great resistance and opposition!
Because Su Mo did this, it seems that he has overturned the table of the pesticide factory.
In fact… it is to destroy many hospitals in disguise!
After the blind regain their sight, the first thing they do is to throw away the crutches in their hands.
After completely solving the harm of pesticide residues, people’s incidence rate will be greatly reduced.
At that time, the business of major hospitals and major pharmaceutical companies will obviously show a downward trend.
But for Su Mo, his favorite thing to do is to give pharmaceutical companies a big tip!
No matter whether those who can drink special water, eat special fruits and vegetables, and are free from the poisoning of pesticides will agree to the promotion of laser insect killers.
Su Mo only hopes that the sky of Longguo will be blue, the water will be clear, and the food and fruits and vegetables will be safe to eat in the future!
The citizens of Longguo can be free from the torture of diseases caused by pesticide residues and food safety issues.
As for how many people’s tables will be overturned and how many people’s interests will be ruined by doing this…
Su Mo said it doesn’t matter, just do it if you don’t agree!
Thinking of this…
Su Mo once again put all his attention on the excitement
On the light mosquito killer.
If we want farmers to be able to use laser mosquito killers, the first and most important thing is the cost.
If it costs tens of thousands or even hundreds of thousands to kill pests in one acre of land, then why bother developing it~
Fortunately, the research and development cost of laser mosquito killers is not high.
According to the system introduction, laser mosquito killers, like many agricultural machinery, are also divided into multiple models.
According to the power and control range, there are ten levels from level 1 to level 10.
Level 1 laser mosquito killer can cover the killing of pests in 666.7 square meters, that is, one acre of land.
Level 2 can cover the range of 10 acres, and level 3 can cover the range of 50 acres.
The highest level 10 can cover the range of 1,000 acres.
As for the cost…
The cost of a level 1 laser mosquito killer, if it is mass-produced according to the assembly line, plus a nuclear diamond battery, is about 100,000 dragon yuan.
Although the price sounds expensive at first, it is actually not expensive at all.
Because the target consumer group of laser mosquito killers is not farmers.
Instead, it is sold to agricultural machinery operators, just like combine harvesters.
Therefore… even if the cost of laser mosquito killers is only 30,000 to 50,000 yuan, Su Mo does not plan to sell them directly to farmers.
Just like no one would buy a harvester to harvest rice and wheat for those three or five acres of land, right?
And how many farmers can use this kind of agricultural machinery without professional training?
Expect those old men and women who farm in the countryside and can’t even use smartphones to use this high technology?
What a joke!
Therefore, laser mosquito killers can only be sold to agricultural machinery operators.
After they have undergone strict on-the-job training, they can make money by killing insects.
Just like the use of Dajiang Plant Protection UAVs to spray pesticides, which has become popular in rural areas in recent years.
It costs 60,000 yuan to buy a Dajiang T60 plant protection machine, and then buy a pickup truck and a generator.
According to the market price of 5 to 6 yuan per mu, excluding the cost of charging and eating, drinking and defecating, one mu of land can earn about 3 yuan.
If you work non-stop for a day, you can spray more than 1,000 mu in 9 hours, which means a net profit of 3,000 yuan.
But normally, as the competition in this industry becomes more and more fierce, there is not so much work for you to do.
Many people can work more than 100 mu a day and make a net profit of 300 to 400 yuan.
At least you don’t have to go out to work, and you can earn money at home every day with your wife and children.
However, the investment cost of the laser mosquito killer is about the same as that of the Dajiang plant protection machine.
In this way, the most critical problem of large-scale promotion is solved!
