Refuse to "demonize" pesticides and fertilizers

In recent years, for fertilizers and pesticides, some people believe that the two are harmless and completely "demonize" them; some people believe that to protect the ecological environment and promote the green development of agriculture, they should abandon their use
.
At the same time, the promotion of some people has caused people to "talk about fat discoloration" and "talk about medicine discoloration
.
" Can it be done without chemical fertilizers and pesticides in food production? Expert: No way! Efficient and rational use of pesticides and fertilizers is essential to agricultural production and food security
.
Chemical fertilizers are highly efficient nutrients that can provide nutrients for crop production, improve crop and soil nutrient levels, and increase agricultural productivity
.
The significance of pesticides is mainly to protect food production through the prevention and control of plant diseases and insect pests
.
People should be treated with medicine when they are sick.
Similarly, when crops have disease and insects, they also need to use pesticides to prevent and cure diseases
.
"Zero growth" is not equal to "zero use".
The meaning of "zero growth" lies in improving the utilization efficiency by improving product quality, developing new and efficient products, and improving application methods to achieve the effect of reducing the application of pesticides and fertilizers and being environmentally friendly, thereby ensuring agricultural production Sustainable
.
Why is the use of pesticides in my country declining, but the output is increasing? Looking at the relevant statistics of pesticides, we must pay attention to distinguish between the original drug and the preparation.
The two cannot be directly compared by the size of the data
.
The main reason for the increase in pesticide production is that China is a major producer and exporter of pesticides, and exports account for a large part of the production of pesticide technicals
.
Export is an important way out for the development of China's pesticide industry
.
The use of pesticides is seasonal, and the investment in pesticide production equipment is large and the continuity requirements are strong.
If they are only produced during seasonal use, most production companies will face more equipment aging, environmental protection and safety issues, and at the same time Not enough to support its various costs
.
Therefore, it is necessary to open up the global market before China's pesticide industry can develop in the direction of continuity, modernization and automation
.
Grew up on fertilizers and pesticides? Let’s take a look at what experts say about using chemical fertilizers unscientifically is like unreasonable diet.
The problem lies in the way of food intake, not the food itself
.
Some fruit farmers and vegetable farmers blindly pursue large fruits and super-high yields.
They invest a lot of nitrogen fertilizer and ignore the combination of other elements, resulting in too much fruit and too much water, but the soluble solids and sugar content can't keep up, which reduces the flavor; the standard for evaluating the safety of agricultural products It is not whether pesticides are used or not, but whether the pesticides are used in a standardized manner and whether the residues are within the allowable range
.
To determine whether pesticide residues have an adverse effect on health, it must be related to the dosage
.
In fact, as long as pesticides are used scientifically and rationally, safety intervals are strictly enforced, and dosages are restricted, pesticide residues can be degraded to within the scope of safety standards, so agricultural products are also safe
.
How to reduce the amount of fertilizers and pesticides? In-depth promotion of the reduction in the use of chemical fertilizers and pesticides is the development direction of green agriculture, and it is also a complex system engineering that requires efforts from all aspects
.
It is necessary to improve laws and regulations, strengthen the supervision of the use of fertilizers and pesticides, and continuously improve the ability of scientific fertilization and scientific guidance services by strengthening the construction of the grassroots agricultural technology extension system
.
Agricultural producers must increase their awareness of saving fertilizers and medicines, and increase penalties for illegal use of pesticides and non-compliance with the safety interval for pesticide use
.
Only by taking multiple measures can we effectively reduce the use of chemical fertilizers and pesticides and ensure the safety of agricultural production and the quality of agricultural products
.
Completely abandon the use of fertilizers and pesticides? Impossible, no need! What mountain to sing and what song, generation has the mission of generation
.
The use and understanding of chemical fertilizers and pesticides is also an inseparable historical process.
Neither can we deny all of its contributions because of individual cases, nor can we fail to see the current achievements because of past problems
.
On a larger scale, not just chemical fertilizers and pesticides, whether it’s the merits or demerits of a certain type of agricultural input, or the pros and cons of a certain new agricultural technology, it should not be "a stick to kill" or "a handful".
The simple judgment of "God" should be based on a big historical view and a scientific attitude.
Otherwise, others will follow the trend and blindly follow the trend, and the development of modern science will be delayed unconsciously
