preface

Desertification control has always been a key focus in China,Nowadays, China has become the country with the fastest growth of forest resources and the largest area of artificial forests in the world, making tremendous contributions to the construction of global ecological civilization.

According to reports, China's independently developedHigh tech equipment such as "sand swallowing giant beasts"The dream of large-scale greening of deserts has become a reality.So what exactly is a 'sand swallowing monster'? How did he help us combat desertification?

Desertification threatens human living space

People's first impression of deserts is alwaysLong yellow sand and endless sand dunes. But in this arid desert with extremely scarce vitality,Only a few plants can survive in such harsh environments.

It is even more difficult for humans to survive in this desert. However,In recent years, the desert has become even more difficult, making the originally oasis like villages constantly become a cage of yellow sandThis phenomenon is often referred to as desertification.

Desertification poses a serious threat to China's ecological environment and economic and social developmentStrong sandstorms not only pollute the air, but also sometimes force the suspension of transportation, and even cause traffic paralysis.

Yellow sand flies freely, blocking waterways and polluting water sources. It has had a serious impact on the safety of human drinking water. In addition, the desert will also encroach on the surrounding agricultural land,This has led to a significant decline in the number of cultivated land, posing a threat to farmers' food security.

Faced with the severe situation of desertification,China has taken measures such as large-scale desertification control and afforestation. In order to green the sand prevention line, scientific researchers have cultivated a large number of drought and salt tolerant plants.

Countless volunteers have been standing on the front line for a long time, planting trees in the desert. They use their youth and sweat to protect the hope of the earth turning green again.Although the road is long and difficult, as long as one keeps green and steps forward, they will surely be able to overcome the desert and open the door to vitality.

The Course of China's Sand Control: From Wheat Straw Grid Method to Modern Multifunctional Sand Fixation Vehicles

China has a vast territory, and desertification has always been a major problem that seriously troubles us. According to statistics,By the end of 2021, the desert area in China has reached approximately 1.28 million square kilometers, equivalent to the size of three Yunnan provinces.

This has seriously affected and damaged the surrounding environment and people's lives. So,How to effectively control desertification and achieve greening in desert areas has always been a highly valued issue in China.

In the early days, China had already attempted to use artificial planting to control desertification.Due to the relatively backward technological conditions at that time, a large amount of manpower could only be utilizedLay straw and other vegetation on the sandy land, gradually forming a fixed size grid circle.Then, artificial planting of herbaceous plants is carried out within this grid circle, which is the traditional wheat straw grid method.

Although this wheat straw grid method is not technically advanced,But at that time, it was the simplest, direct, and effective way to control desertification.

Its principle isBy increasing the roughness of the sand surface itself, reducing wind speed, and forming a wind wall, the goal of reducing wind erosion is achieved. However, this method also faced problems such as high labor consumption and low operational efficiency at that time.

Over time,The wheat straw grid method was gradually proven to be a very practical method in the process of desertification control at that time.Among different graphic comparisons, using a square shape has the best sand fixation effect.

This is mainly because,When the wind blows over the sand surface, it will be hindered by the grid boundary to some extentThis weakens the wind force. At the same time, the rolled up sand particles will also be blocked by the wheat straw grid and re fixed back to the original sand.

This not only slows down the wind force, but also achieves the goal of re fixing the moving sand particles.

With the rapid development of technology,China's desertification control has entered an era of mechanization.

A modern machinery called a multifunctional sand fixation vehicle has been successfully developedThis type of vehicle integrates multiple functions such as vegetation laying and protective forest planting, and can achieve remote intelligent control, greatly improving the efficiency of sand control operations.

This multifunctional sand fixation vehicle uses an onboard robotic arm to lay grass squaresThen, through precise positioning, mechanized planting of protective forests is carried out within the grid, and the vehicle is also equipped with an intelligent navigation system.

This mechanized and efficient operation method enables large-scale sand control to be achieved,We have truly reversed the situation where the speed of desertification exceeds the speed of greening.

It can be said that from the initial straw grid method to the current multi-functional sand fixation vehicle,The desertification control in China has gone through a progressive process from pure manpower to mechanization.

With the development of technology, the efficiency of desertification control has also been continuously improved. We are confident that we can use more advanced scientific and technological means to thoroughly address the problem of desertification, and ensure the ecological environment and national security of our country.

Multifunctional Sand Fixing Vehicle - A New Weapon for Mechanized and Efficient Desert Management

China has successfully developed a multifunctional sand fixation vehicle, which has brought new hope for desert management.This type of vehicle combines the wisdom of multiple units such as research and development design, engineering and manufacturing, and adopts a diesel engine and four-wheel drive chassis.

The vehicle has a length of 20 meters and a weight of up to 50 tons, making it very powerful.It can carry out various desert management operationsFor example, quickly laying grass squares to establish sand barriers, pruning shrubs, sowing and fertilizing.

The main innovation of this car lies in the integration of multiple functions. The car is equipped with a powerful cutting device that can easily cut tall shrubs,The carriage can also carry a large number of wheat straw squares.

The rear of the car is equipped with an automated laying system that can accurately insert grass squares into the sand at a depth of about 15-20 centimeters. This sand fixing vehicleApproximately 5600 square meters of grass squares can be laid per hour, equivalent to 40 acres of landFar exceeds the efficiency of manual work.

Except for laying grass,This type of vehicle can also accurately map the work area and intelligently plan the work route based on the terrain and topography.

It is equipped with a sowing and watering system, which can directly plant sandy vegetation such as shuttle and Artemisia annua on the grass grid, and apply fertilizer to promote growth. Currently,This technology has been tested in Gansu and other places, and has achieved very good results.

It can be seen that the multifunctional sand fixation vehicle has achieved mechanization, automation, and intelligence in desert management,.

Although the development of multifunctional sand fixation vehicles requires a significant investmentHowever, considering its long-term usage cycle,.

Compared to the traditional manual desertification control model that requires continuous payment of wages to desertification control workers,.

A multifunctional sand fixation vehicle can complete the workload of dozens of people per day.No artificial fatigue will occur..
