Military Technology

After attending the reception banquet held by Deputy Secretary Li for them, Wu Hao and the others were immediately arranged to rest in the hotel.

Of course, the conditions of the hotel are definitely not as good as those in Urumqi. But in such a place with tens of thousands of people, it is not bad to have this condition. At least it is clean and comfortable, no different from ordinary business standard rooms.

At three o'clock in the afternoon, Wu Hao and his group began to visit the farm near the iron gate under the leadership of the personnel arranged by Deputy Secretary Li.

After a round of investigation, the sights they saw really benefited them a lot. One is the traditional agricultural method, which is actually the first few farms developed and constructed.

Basically, it is to plant trees in the desert first, and enclose the desert into a piece of area. When the trees survive and grow, they also play the role of windbreak and sand fixation.

The circled area is planted with crops such as wheat, corn, soybeans, sorghum, and cotton.

This is also the most commonly used method in the entire Xijiang farm, mainly based on this large-scale extensive agriculture. In fact, this is also in line with the actual situation in desert areas. After all, it is difficult to achieve intensive farming in such a harsh environment.

The second type is the large-scale sprinkler irrigation agricultural technology developed in the past ten or twenty years.

Large-scale sprinkler irrigation is actually the use of sprinkler irrigation technology to supplement water for crops planted in the arid and barren sandy soil of the desert. Moreover, according to these sprinkler irrigation pipes, fertilizers or insecticides and pesticides can be continuously provided to these crops.

There are many kinds of sprinkler irrigation technologies. In addition to the common shower sprinkler irrigation methods, there are actually grid elevated sprinkler irrigation technologies and central pivot sprinkler irrigation technologies.

We often see very regular circular oases in the western desert when flying by plane, which is the result of the large-scale center pivot sprinkler irrigation technology.

Although sprinkler irrigation technology saves a lot of water compared with traditional aqueduct immersion irrigation, it still has its own shortcomings.

For example, sprinkler irrigation can only spray water and fertilizers to the surface of crops, while desert areas are relatively dry, with high temperatures and large evaporation. The water sprayed to the surface is easily evaporated, making it difficult to moisturize the roots of crops.

Especially in the arid environment of the desert, every drop of water is hard-won. Therefore, how to use water sources more efficiently for irrigation has become a topic that everyone is studying.

In the 1950s and 1960s, Izreel, as a newly established state, faced a severe food crisis. In order to avoid long-term dependence on imports and possible food famine, Ezreel spent huge sums of money to complete the 145-kilometer "North-to-South Water Diversion" water pipeline in 11 years.

However, traditional irrigation has slowed progress in agricultural technology and desert reconstruction. At that time, most of the territory of Ezreel was a desert area, so water was the lifeblood of rebuilding the desert.

But in such an arid desert area, the water source is very tense. The people's domestic water is not guaranteed, let alone the water used for production and agriculture.

Until the 1960s, a farmer accidentally discovered that the crops where the water pipe was leaking looked exceptionally good. Water penetration into the soil at one point is the most effective way to increase cooling, efficient irrigation, and control water, fertilizers, and pesticides.

This discovery immediately won the strong support of the government, and the world-famous Netafim drip irrigation company came into being immediately.

After the inventor of drip irrigation, the total agricultural water consumption in Ezreel has remained stable at 1.3 billion cubic meters for 30 years, while the agricultural production has increased by 5 times.

Our country has actually introduced this set of drip irrigation technology a long time ago.

And according to our actual situation, relevant improvement and optimization have also been carried out, and innovative development has been carried out on the original technology.

It can be said that our country is not weaker than other countries in the world in terms of drip irrigation technology.

The special environment in Xijiang also allows drip irrigation technology to take root here and continue to develop. According to the actual situation, a set of fully automatic dripper technology that is leading in the world has been developed here.

In the imagination of many people, drip irrigation technology may be simple after all. In fact, it is indeed very simple, that is, to poke some small holes in the thin tube, and then make the water in the tube drip onto the roots of the crops.

It seems so simple, but in fact it is very complicated to let the water drip into each plant in a balanced manner. It should be known that the length of a water pipe is different, and the water pressure of each part of the water pipe is also different, so the amount of dripping water in the small hole is also different.

In order to maintain the same water output in all parts of the water pipe, it is necessary to conduct a large number of research and development tests on functional modules such as hard, tough and corroded plastic pipes, connectors, filters, and controllers, so that they can meet the design and use requirements.

Today, dropper technology has been automated and intelligent. The computer automatically detects the soil humidity of the root system of the crops, and then adjusts the water output. And it can also regularly infiltrate the water containing fertilizers and pesticides into the roots of the plants.

The successful application and development of this set of technologies can not only save water resources, especially in arid desert areas, it is even more important.

Moreover, this technology can be used to replant vegetation and crops in the already barren desert, which can not only restore the damaged ecological environment, but also produce more agricultural and sideline products. Help these poor areas solve the food crisis, and even revitalize the local economy.

After this round of investigation and visit, it also opened Wu Hao, Xu Xiaoya and others' eyes, and even changed a lot of their previous stereotypes about this area.

For example, they naively thought that desert areas must be barren and barren. But when I got here, I realized that there is such a vibrant place in the depths of the desert.

For another example, they thought that most of the deserts like Xijiang were short of products. And their previous understanding of this place was limited to raisins, cantaloupe, and camels.

But this time, they really saw the rich side of Xijiang's products here. In addition to the most basic crops mentioned above, what they didn't expect was that rice was also grown in Xijiang.

And it is said that the rice produced here is of excellent quality, comparable to Northeast rice. In addition, there are sunflower, hops, lavender, flax, tobacco leaves, medicinal materials and so on. The output and quality of XPCC's upland cotton, long-staple cotton, colored cotton, sugar beets, oil crops, hops, and tomato paste rank first in the country's land reclamation.

In addition, there are a large number of melons and fruits. In addition to tropical fruits, melons and fruits from other places are available here. What is not available in other places is also available here, and the quality is better.

Not to mention some other characteristics of Xijiang, such as the beef and mutton in Xijiang, which is the best beef and mutton producing area in China.

As for whether Wu Hao is the best or not, they don't know, anyway, that's how the tour guide introduced it. But judging from several skewers, the lamb here is really delicious. Even a relatively self-restraining woman like Xu Xiaoya didn't care about her status as a female president in front of so many delicacies.
