Recently, a news about the transformation of terraces has caused controversy, the county has carried out a "stone masonry" transformation of terraces, the transformed terraces are not only very different from the traditional terraces, but also caused a lot of controversy, what is the problem with the transformed terraces?
And what's in it for you?
1. The relationship between new technology and tradition.
In promoting modernization, it is necessary to comprehensively consider traditional culture, ecological environment, and modern technology.
The progress of modern technology has brought convenience to people's production and life, but it is necessary to be cautious when promoting new technologies, because the blind pursuit of new technologies is likely to destroy the traditional foundation of sustainable development.
Under the transformation of modern technology, the traditional farming method has undergone great changes, people no longer use traditional manual farming, but use tractors, seeders and other agricultural machinery, which not only reduces the labor burden of farmers, but also improves the efficiency of agricultural production.
However, there are also some problems with agricultural mechanization, such as the use of agricultural machinery, the organic matter content in the soil of farmland is decreasing year by year, and the yield of rice is also declining.
This is because agricultural mechanization will turn the organic matter in the soil to the surface layer of the soil during the cultivation process, and the organic matter content of the soil surface layer is far from the required amount, so the fertility of the soil will decline year by year.
In addition to this, agricultural mechanization destroys the structure of the soil, making it softer and softer, and its ability to retain water and nutrients is weakened.
Therefore, while developing modern agriculture, it is also necessary to pay attention to the protection of soil fertility and ecological environment, promote ecological agriculture, and better protect the fertility of farmland soil.
Agricultural mechanization is not suitable for use in all places, for example, in some mountainous and hilly areas of the mainland, the terrain is more complex, the use of agricultural mechanization, not only is it inconvenient to operate, but also destroys vegetation and aggravates soil erosion.
Therefore, when promoting rural construction, it is necessary to respect the opinions of farmers and local cultural traditions, listen to the voices of the grassroots, and promote the sustainable development of the project and the benefits of the local people.
In the development of agriculture, it is also necessary to choose suitable planting methods according to the actual local conditions, fully consider the needs of crop growth, and avoid affecting crop yields due to technological transformation.
Second, the transformation of terraces has caused controversy.
In recent years, a county has carried out "stone masonry" transformation of traditional terraces, and the transformed terraces are not only very different from traditional terraces, but also have caused many controversies.
Some people believe that the renovated "stone ladders" can not only improve land utilization, but also improve the efficiency of water conservancy facilities, but others question that the renovated terraces are difficult to ensure water supply, affecting rice growth and reducing yields.
When implementing similar projects, the government should fully listen to the opinions of experts and the public, and conduct scientific assessment and demonstration, so as to avoid irreversible damage caused by blind decision-making.
Terraced fields are the ancient agricultural planting methods of the mainland, which can not only make use of limited land resources, but also make full use of water resources, the crystallization of the ancient wisdom of the mainland.
Moreover, in the process of terrace planting, a kind of ecological agriculture of "water and fertilizer integration" will be formed, which can not only protect the land, but also reduce the waste of water resources.
In the process of construction, the terraces need to be planned and designed as a whole according to the terrain characteristics of the mountains, so in the construction process, a lot of manpower and material resources are often consumed.
Therefore, it has been proposed that stones can be used to build terraces, which can not only improve land utilization, but also save construction costs.
Therefore, under the implementation of the government, a county transformed the traditional terraced fields, dug up all the soil in the terraces, and then used stones to build the terraces one by one.
The renovated terraces not only greatly improve the land utilization rate, but also use the minerals in the stones in the planting process to play a certain role in nutrients.
However, some people have questioned that the renovated terraces cannot guarantee the supply of water, which has affected the growth of rice.
3. What's wrong with the new stone staircase.
With the transformation of the terraces put into use, people found that the transformed terraces have a big problem, first of all, the transformed terraces are difficult to ensure the uniform supply of water, this is because the middle part of the transformed terraces is stones, and the permeability of the stones is very poor, when the water flows from the edge of the field to the center of the field, due to the obstruction of the stones, the amount of water will become less and less.
Secondly, if rice is planted on the terraced fields, the root system of the rice will grow under the stones, so that the phenomenon of "water seepage" will occur during irrigation, resulting in the rice root system not being able to absorb sufficient water, thus affecting the growth of rice.
In addition, cracks will appear in the stones in the terraces after the transformation, and the salt content and pH content in the stones are also increasing year by year, which is very unfavorable for rice cultivation.
Some experts said that the transformed terraces are not as suitable for rice growth as the traditional terraces, and after two years of investigation and research, comparing the yield of the transformed terraces and the traditional terraces, it was found that the yield of rice in the transformed terraces was 10% lower than that of the traditional terraces.
epilogue
In fact, this account cannot be calculated casually, although the transformed terraced fields are not suitable for growing rice, but they are suitable for planting other crops, so when implementing similar projects, the government should fully listen to the opinions of experts and the public, and conduct scientific evaluation and demonstration.
The protection of traditional culture and the ecological environment is not only a cultural responsibility, but also an important consideration for future sustainable development, and it is necessary to find a balance in development.
