Vol 2 Chapter 193: Fish farming in the desert?

In fact, it is not just the Three-North Shelterbelt and other shelterbelts. In the greening of northern cities, fast-growing poplars are widely used for greening because of their high survival rate, fast growth rate, and low price. Mobile terminal: https: // m.
The result of this can be that in April and May each year, a large number of "white hairs" wreak havoc on the world, causing major distress to the citizens. These fluffy dances are like dare not to open the doors and windows, which seriously interfere with sight. Even when walking, you must always pay attention to safety.
And it is extremely flammable, it is easy to cause fire, and brings hidden dangers to public safety. Some citizens who are allergic to willow catkins are even more miserable. These irritate and aggravate respiratory diseases such as asthma and chronic bronchitis, which is not healthy. It will even interfere with industrial production research activities and affect the accuracy of precision instrument measurements.
Now the municipal departments of cities have realized the shortcomings of this kind of fast-growing poplar, but they have been planted too much and in large quantities, and most of them have become forests. It is basically impossible to cut off and remove it all at once, it can only be replaced slowly.
In response to the current problems of fast-growing poplars, the municipal government has also made a lot of efforts. The most important thing is to "sterilize" these fast-growing poplars.
There are three main types of sterilization operations for fast-growing poplars. One is to spray the fast-growing poplars every April or May each year to prevent them from blooming, thereby controlling the problem of flying floc.
The second type is also similar to the first type, but it uses the technique of tree circumcision to suppress the flowering of these fast-growing poplars.
The first two are symptoms, and they need to be treated once a year, so it takes time and effort. The third method is relatively straightforward. By using the grafting method, fast-growing poplars are grafted onto other tree species, so that fast-growing poplars will not produce tidbits.
But for such a shelter forest in the desert, you don't need to have such trouble. Crowd prevention needs to be considered in cities, but not here. According to Du Xiuming, in April and May of each year, the relevant helicopter flight spraying is completed once, which is simple and easy.
Also, such a desert area is sparsely populated, and it seems that there is no need to consider any flying effects.
Wu Hao chose a water conservancy facility 40-50 kilometers away at the last stop of the farm. This water conservancy facility was originally there. Just because Wu Hao started this smart unmanned farm project, it will also be expanded and renovated here.
A water pipeline will soon extend from here to the farm to provide water irrigation for the farm's crops.
Of course, this is a desert, not the interior, so water is vital for both humans and livestock and crops.
In order to attract Wu Hao, they built the farm in Tiemen. However, the second division gave up a lot of capital and actively gave this water conservancy facility to Wu Hao for their use.
However, after Wu Hao and their location were determined, they couldn't just take over. They still understand why they choose to use Li and return to Tao.
Immediately promised to invest in the reconstruction of this water conservancy facility, so that it can meet the needs of Wu Hao and their original irrigation users.
Although the iron gate is in the desert, it is actually water. Every spring and summer, glacial water that melts from Kunlun flows through it, forming an oasis in Tiemen.
Therefore, Tiemen has always been an important town and residence gate in ancient times. You must know that in this arid and deserted area, whoever controls the water source controls everything, so it has become an important town in ancient times.
Of course, now this function is lost here, but it does not prevent it from being a major town in the desert.
In addition to the rivers that flow here, in addition to bringing people living in water and irrigating crops, a large part actually flows into the desert and disappears. This is what we often call inland and seasonal rivers.
The famous Tarim River belongs to this kind, and there are many rivers like this in the southern Xinjiang desert along the foot of Kunlun.
However, in the past, with the continuous increase of people's water use and the backwardness and arrogance of irrigation methods, many rivers have been cut off and dried up.
随着 With the adjustment of industries, the upgrading of irrigation technology, and related protections over the years, many rivers have resumed flowing.
Wu Hao Their reconstruction of this water conservancy facility is actually to expand the capacity of the water conservancy facility to prevent overuse and make it dry up.
Wu Hao originally thought that the water conservancy facility was a dam and a reservoir, but after that, he found that it was completely different.
This water conservancy facility is a dam, but this dam is different from the dams we usually see.
In short, this is an artificial oasis wetland, a table full of Populus euphratica wetlands. According to the person in charge here, the dam was built in the 1950s and 1960s and was originally designed for irrigation.
At the time, in order to prevent excessive evaporation, some populus euphratica forests were planted in the dam, on the one hand, to conserve water, and on the other, to prevent evaporation.
But I didn't expect that the Populus euphratica here slowly began to breed and grow up, gradually covering the entire dam, forming a large area of ​​Populus euphratica.
I walked slowly along the water's edge, and some reed plants were growing. The veterans of the regiment who came from the mainland saw this and tried to raise fish in the dam ~ EbookFREE.me ~ I did not expect that the breeding was successful.
With the water, the fish, the water grass and the poplar, it attracted many birds. This has also made it an important natural ecological wetland reserve in the entire western Xinjiang, and a special protection station has been set up.
Although it has become an ecological wetland protection area, in order to meet the needs of people around and downstream for drinking water and agricultural irrigation, this dam is still operating to provide water for the downstream and surrounding areas.
It is only controlled within a reasonable range every year and must not affect the ecological environment here.
The main purpose of this reconstruction is to expand the capacity. On the one hand, the silt under the river and water area is cleared to increase the reservoir capacity. The other side is to expand the entire wetland area, thereby increasing the storage capacity and wetland water content.
So the whole reconstruction process is very troublesome, not just investing money for construction, but also considering ecological issues. Even for the entire dam expansion project, they have been criticized by some experts in ecological protection.
But this is a real need, and such a large project cannot always be stopped because of a few criticisms from these experts.
So Wu Hao ’s approach is to include these ecological protection experts in the dam expansion project, and let them make suggestions and give play to their role to minimize the adverse impact on this ecological wetland reserve.
[Check the relevant information, in some areas of southern Xinjiang, there are indeed such wetlands, not only fish, but also characteristic canoes. 】
