Big River surging 丨 The vitality of the green corridor

This is an ecological corridor that is almost swallowed by the desert. The Tarim River is its lifeline. For decades of governance, the green corridor of the lower reaches of the tower river has been "dying" to "Rongguang Give". In the cotton corridor in nearly 400 kilometers, human society and vegetation are restoring their vitality. The desert is still jealous, and the efforts of confrontation have never stopped.

The group without water almost moved away

31, 33, 34, within 400 kilometers downstream of the tower river, this is not just a string of numbers. This is the three delegations of the second division of the Xinjiang Production and Construction Corps in the lower reaches of the Tower River, and it is also a monument to the lower reaches of human society in the lower reaches of the Tower River to renew and then revive.

The green trees in August 31 are lush and peaceful, which is not only in the street, but also in the hearts of people. "Now people's hearts are stable," said Zhou Qiang, employee of the group. He left the 31st regiment in 2001 and wandered for 10 years. Similar to him, there were constant people going out in the lower reaches of the tower river. By 2006, there were less than 500 people with more than 2,000 people.

The reason is very direct: the downstream of the tower river is broken. "There is no water," Zhou Qiang said, "I can't survive, and even the group is considering relocation."

However, with the gradual development of the Tower River ecological governance, the water came to the lower reaches of the tower river, and the year was stable every year. With water, people returned to their homeland one after another. Zhou Qiang also returned to his hometown in 2011. It has been shining for another 11 years.

This precious water comes from thousands of miles.

"If there is no systematic governance measures, the downstream water is extremely difficult to achieve." He Yu, director of the water volume dispatch management department of the Tarim River Basin Management Bureau, said that an important indicator of the first phase of the Tahe River is Xiao jackets break the noodles, and the amount of water leakage cannot be less than 4.65 billion cubic meters each year. The amount of water leakage is guaranteed, which means that the economic and social water use of economic and social water along the downstream has a basic guarantee.

Since the beginning of this year, the watering of the Tahe River Basin has become more scientific. On the basis of ensuring the ecology, more water has been used for economic and social development. When the cotton drinks water, it will grow better. There is a copy of the 31 -blocks of cotton tedies. After returning to his hometown, he planted the cotton he was best at taking care of it until today. In the lower reaches of the Tower River, there are countless cotton households like him.

The largest yield at the tail

One drop, two drops, three drops ... the crystal water fell accurately on the cool ground, and the drip irrigation belt was swaying on the cotton. "Last year, my 68 acres of cotton land was produced 512 kg. The target this year was 560 kg." Wang Fanger looked at his land, and his eyes flashed with confident light. The employee of the 34th regiment is ushered in another harvest of cotton.

The 34th regiment is a group, known as the "tail of the mountains". It is the raging ground of the southern edge of the Taklama Ganan Desert. After the precious tower river flows here, it is not unmanned until it is injected into Lake Tama Tama, Tima. Like the 31th regiment, it was once faced with the extreme deterioration of the ecological environment.

But now, the cotton fields are vast here, and the average yield of cotton is about 500 kilograms. The extremely critical reason is that it is precisely all methods to use all the methods to effectively use those precious water like gold.

"The position of our group is the tail of the limelight, with a lot of disasters and small water resources. However, through the continuous strengthening of the intensive use of water resources, it has promoted the high -quality and high yield of cotton." Said Liu Gang, deputy head of the 34th regiment. After years of infrastructure construction, the water -saving system of fields represented by drip irrigation from channels, the high -efficiency water -saving system of the 34th regiment has been very sound, but the water is still lacking. What do you want to save water again?

Agricultural technology has become another extension of the 34th regiment water chain. "This year, the whole group used the" sub -filled water spring irrigation 'technology to plant the cotton area of ​​98,200 acres to achieve 11 million cubic meters of water. "Liu Gang said," It can not only meet the water field sowing in the cotton field The water is about 120 cubic meters. At the same time, it has the sowing time earlier for at least ten days, which means that at least the cotton has an extra growth period of ten days. This is very important for cotton. "

"Since the 1990s, we have explored various water -saving modes. From the childbearing period, the normally pressure drip irrigation, the deep -buried drip irrigation of the orchard to the today's" subfilled water spring irrigation ', the technology is constantly improving. "34 34. Luo Jianhong, director of the Group Agricultural Development Service Center, said.

Research on governance deep in Hu Yanglin

About ten kilometers downstream of the Daxi Sea Reservoir in Weili County, a sand and gravel roads winding into the deep forest of the euphratica forests. After the forest seven or eight kilometers, a sign with "scientific research" appeared. The team of Deng Mingjiang, an academician of the Chinese Academy of Engineering, is here to conduct a far -reaching research on the ecological governance of the lower reaches of the tower.

"Here is our '轮 osmotic wheel irrigation ecological repair test area'," said Ling Hongbo, a researcher at the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences. The use of more efficient, intensive, more accurate. "

At this time, it was the seasons of Populus euphratica, and walked into a seemingly barren forest land. Jing Weimin, an engineer of the Xinjiang Shengcheng Institute of the Chinese Academy of Sciences, squatted down and gently pulled away the crowds of Populus Yangxu on the ground. "Nothing." The reporter looked blank. "Look at it again." Jing Weimin said with a smile. The reporter attached to watch it intently. Under the white porridge, the new green of only about 1 mm was screened. "That's the young seedlings of Populus Populus." Jing Wei Police has a gentle temperature. Not only under the feet, there are side on the side, and there is also a forest wasteland in front of it. This seemingly dry soil is a seedbed that is bloomed deliberately at the millimeter scale. "By simulating a variety of overflow modes and combining monitoring, we can find the time and method that can most promote the germination of Populus euphratica seeds." Jing Weimin said.

More than that, in the experimental area with a small area but a complete landform, the ditch is distributed in different slopes, and various monitoring facilities are scattered in the forest. "We explore the optimal irrigation routes and methods of ecological water between the ecological water, and solve the accurate, efficient and scientific use of ecological water from the river to the forest area 'last mile". "Ling Hongbo said.

This test area is a starting point for a grand project. "From the perspective of the big aspect, we aim to combine the Tarim River Basin Authority to establish a rotchial irrigation system that integrates irrigation partitions and 'Daxiko Reservoir -Tarim River -Tema Lake" Lake "Lake" Lake " . "Ling Hongbo said," On the one hand, the area of ​​ecological water in the lower reaches of the lower tower river is expanded; on the other hand, through the leakage, the ecological water stores in the relatively closed geological structure along the downstream. Ecological protection and repair effect. "
