Scientific rambling
For most people, rice has always been grown in paddy fields, but I heard thatRice is able to grow in the mountainsAnd the yield is alsoUp to thousands of kilograms, incredible, indeed.
This technology is undoubtedly one of the agricultural fields in our countryA major breakthroughIt may even become a means of black science and technology innovation to help alleviate poverty in arid areas.
So, what exactly is "rice up the mountain"? There are rumors of this new way of growingThe per capita production is staggering, up to 1,000 kilograms, whether this statement is true or false, and this technologyWhether it will cause potential damage to the ecological environmentThis?
This new type of agricultural cultivation technique, referred to as "rice uphill", is actually an innovationHybrid rice rain-fed dry seedscultivation methods.
In short, it isHybrid rice varieties from "paddy fields under the mountains" were introduced to the "dry land on the mountains" for planting, getting rid of the traditional way of planting paddy fields. There is no longer a need for cumbersome processes such as rice soaking, seedling raising, and transplanting, even in the case of water scarcity, it is able to maintain high yields.
In the beginning, experts used it to teach local farmers new planting techniques"Dry cultivation of rice".The official terminology. However, since farmers do not know much about "rice dry planting", the terminology of experts seems a little jerky.
Therefore, in the process of communication, the farmers put forward a more vivid and easy-to-understand statement, that is, the "rice up the mountain" that was widely spread by everyone later.
This new technology relies on advanced genetic improvement methods to better adapt to various water conditions by breeding rice varieties that are more adaptable and more water use efficientIt thrives during the rainy season and makes more efficient use of limited water resources during the dry season.
At the same time, "rice uphill" emphasizes scientific management, through precise fertilization and reasonable water management, to ensure that rice can get sufficient nutrients and water throughout the growth cycle, so as to improve yield and quality.
Lancang County, Yunnan Province, which is located in a remote and impoverished area with a serious shortage of water resources, was selected for this "rice uphill" experiment. This placeMostly dry landThe staple food is mainly corn.
Due to environmental constraints,Traditional rice cannot survive hereAs a result, local residents can only sell corn in exchange for other food.
In this context, in order to achieve self-sufficiency and subsistence for mountain dwellers, "rice freedom" is realizedThe only way to do this is through self-cultivation.
However, this is not an easy task. As we all know, rice is usually grown mainly in the southern plains and requires abundant water.
However, the goal of the "rice uphill" experiment is to plant rice in the mountains, which are not easy to maintain water and soilLarge-scale and mechanized cultivation faces greater challenges in such an environmentSounds like an almost impossible task.
In order to meet the challenges of the "Rice Uphill" trial, our team of experts demonstrated and promoted it locallyHybrid rice dry planting technologyand solves two key puzzles:
First, in the course of local experiments, experts foundTraditional rice is often difficult to tiller (niè) in dryland environments, resulting in unhealthy plant growth, which directly affects the yield of rice.
However, experts have carefully selected rice varieties that are adapted to dryland environments and have good tillering (niè) characteristics, such as "Dian Heyou 615", which can make better use of limited water resources while maintaining good growth statusImproved adaptability and yield of rice under dryland conditions.
On the other hand, in traditional rice cultivation, due to the characteristics of the dryland environment,Weeds tend to grow quickly, robbing them of water and nutrients, which seriously affected the growth and yield of rice.
So experts have promoted the application of an advanced agricultural technique - before weeds sproutGrass sealing technology
In layman's terms, it is before the weeds germinateMulching grass clippings or mulch blocks the growth of weedsReduced disturbance of weeds to rice growth.
At the same time, the terraces provide sufficient water and nutrients for crops during the growth of rice, and improve the efficiency of water resource useAt the same time, it reduces the idle and waste of land.
Through these technological innovations and improvements, Yunnan has successfully promoted 500,000 mu of rice in 2023, with the highest yield per mu reaching 788 kg and the lowest yield reaching 634 kgThe total production is up to 280,000 kilograms。This has provided sufficient rice production for some areas of Yunnan and solved the problem of food and clothing for farmers.
Among them, the most impoverished village of Haozhiba has a per capita output of more than 1,000 kilogramsThe per capita production is more than 1000 kgIt has opened the door to prosperity for local farmers and brought new hope for agricultural development in other poor areas.
This figure is not only an increase in yields, but also means that farmers are using scientific and technological innovations and modern agricultural methodsGet rid of the shackles of traditional agriculture,Economic independence and sustainable development have been achieved.
Logically speaking, this high-tech rice planting technology should be well received by everyone, but there are some ** and some terraces built on the mountain on the InternetLinking "rice up the mountain" with "deforestation and land reclamation" and high-standard farmland constructionIt has caused many crazy questions from netizens who don't know why.
After verification, these are basically unscrupulous self-**** trying to earn people's attentionSo the malicious editing of **or**.
The person in charge of the project has made it clear that there is no situation such as "opening up mountains and cultivating fields" and "deforestation and making fields" that netizens questioned, and theyPromise not to damage the ecological environment.
As for the so-called "deforestation and reforestation", in fact, these are not the original forest lands in the ecology, but some artificial forest lands that have been built on cultivated land in violation of regulations in recent years. For these illegally constructed forest lands, rectification and restoration are not "deforestation and reforestation".It is not what netizens call "returning forests to farmland".
The state has clear standards and regulations for the construction of high-standard farmland, requiring that the construction be standardized according to local conditions such as geological landform, water resources, and meteorological conditions.
"Rice going up the mountain" is in line with the national construction standards and has practical significance for farmers to grow grainBut in fact, it is difficult to achieve large-scale promotion at this stage.
The most important of these is the adaptation of the environment and climate change to the "Rice Uphill" programme. In simple terms,The world is too "complex", and the geology, landform, and climate vary greatly from place to placeHow to adjust the plan under different conditions so that it can achieve good results in various places is an aspect that requires the expert team to continue to study and adjust in depth in the future.
And the cost issue is also a challenge"Rice up the mountain" requires a lot of high-tech machinery and equipmentLocal farmers need to be trained in planting agriculture expertise to ensure rice cultivation and yields.
Once the "rice uphill" program is implemented, how to keep the terraces in good condition and manage the growth of riceLong-term input and farmer cooperation are requiredSubsequent maintenance and management costs are also an issue to consider.
At present, we can be clear that scientific innovation and improved rice planting techniques, such as rice uphill and dryland planting, are not fooledIt's scientifically proven.
The result of a high yield of 788 kilograms per mu is not boasting, let alone the destruction of forests to create terraces as everyone rumoredIt will not damage the ecological environment.
It's hard to imagine, it's doubtful, but everything should be based on factsWe can't follow the trend and lead the rhythm, so that the agricultural experts who have worked hard and devoted themselves to research will suffer unjustly, let alone let them sweat and tears.
In other words, these seemingly bare dry fields are full of soil, and once they are successfully built, as long as they do not collapse, as long as they are built in accordance with national standardsEven if you watch the sky and eat, you can also "green mountains and green waters"!
Scientific innovation is for the sustainable development of agriculture, and in the Internet age, information is disseminated extremely quickly, but the authenticity of it also needs to be trueWe have a rational heart to discern, based on facts, and not to be influenced by some irresponsible reports and incitement.
