In today's society, the meaning of the word expert has changed in the eyes of many people, and a large part of them have been branded as people who sell their reputation.
In fact, it is no wonder that the people have such a perception, Chairman Mao has a good saying: without investigation, there is no right to speak.
Some so-called experts, without the necessary investigation and practice, have made wild remarks and freely expressed and publicized some unrealistic and misleading remarks, which have caused negative reactions and influences in all fields.
This behavior is ridiculous and even more shameful.
However, there are also some experts on the mainland who are sincere to the people, who are full of theory and practice, and have made various practical suggestions.
Not long ago, an expert fell into this "rare" category, and his suggestions on how to deal with straw were very agreed and convinced by the general public.
So what's going on here?
The implementation of a policy is not without purpose, first of all, here we must understand what are the dangers of banning straw burning.
One of the main hazards of banning straw burning is that it will pollute the atmospheric environment.
Because straw contains nitrogen, phosphorus, potassium, hydrocarbons and organic sulfur, after incomplete combustion, a series of harmful substances will be produced, and in the long run, the atmosphere and air quality will be damaged to a certain extent.
And after being exposed to sunlight, secondary pollutants will also be produced, further damaging the environment.
The second is that the smoke caused by burning straw is full of substances that are harmful to the human body and will affect human health.
Especially for children, the elderly and people with pre-existing respiratory diseases, the impact is even greater.
The third is easy to cause fire, straw as a flammable, in dry weather is easy to ignite, in the mountain forest area this phenomenon, will cause great economic losses and personal and property safety.
Finally, although burning straw can kill some pest eggs, it will also kill microorganisms in the soil that are beneficial to crops and destroy the original structure of the soil.
Therefore, in order to solve the above possible hidden dangers, the mainland began to implement a ban on straw burning.
However, after the implementation of this policy, it caused problems for many farmers and caused many problems.
The expert said that after the implementation of the policy of banning straw burning, many farmers reported that due to the large amount of straw returned to the field, the diseases and pests of their crops were much worse than in the past.
In addition to the problem of crop diseases and pests, the return of straw to the field has also made the original cultivated soil an ideal place for bacteria and insect eggs to develop and grow.
This has undoubtedly brought great trouble to the farmers' harvest.
If all straw is returned to the field, it will be a big challenge to the future land health of the mainland, and many farmers lack effective treatment measures, which will lead to the accumulation of straw in the farmland, which will cause residual harm.
In addition, in order to avoid the impact of returning straw to the field, many places have installed straw crushing devices on harvesters as required, but with it, the cost of harvesting has increased.
The income from farming is already so small, and the cost of input in this regard is also increased, and many peasant masses have generated a lot of resistance.
All of the above reflects the impact of straw burning on agricultural cultivation.
Strictly speaking, this policy also falls into the category of "one-size-fits-all", and after so many years of practical consideration, the straw burning policy that has been banned has been shown to need to be improved.
It's not good to burn, it's not good not to burn, so what should be done?
The key is how to balance the impact of these two hazards, and it is clear that more detailed solutions are needed, and more attention should be paid to the problems reported by farmers.
Especially in agriculture, we must really go to the masses, practice more, and investigate more.
According to the different conditions of each place, make corresponding adjustments and changes, and increase financial support for straw treatment, I believe that a compromise and reliable solution will be reached.
The development of agriculture and the protection of peasants' rights and interests are inseparable, and sometimes some agricultural policies can be appropriately relaxed and measured, and only by being willing to collect and listen to the voices and suggestions of the vast number of peasants can agriculture be truly revitalized.
It can also be seen here that this expert's proposal was indeed put forward from the standpoint of farmers, and must have been concluded after actual investigation, which is really rare.
Finally, I hope that in the future, whether in agriculture or other fields, there will be more such experts who can truly speak for the people.
