In June in Tibet, the ice and snow have melted.
The earth, which has been washed by glaciers and snow water, has begun to gradually warm up.
It is relatively cool at this time, and people may even feel hot at noon. However, even at night when the temperature is the lowest, when people go out, they only need to put on a sweater and a coat.
Every year at this time, Tibetan leaders will patrol along the Maquan River all the way upstream.
There is no way, every year after the snow melts, the river beach will become more barren, and river sand will fly up from the river with strong winds, causing very serious land desertification.
This matter has attracted the attention of Tibetan leaders, who have been trying to find ways to control the desertification problem near the Maquan River and protect the grassland.
Grassland is extremely important to Tibetans.
Tibetan herdsmen have made a living by herding for generations, and livestock are their wealth. Every herdsman wants to have more livestock, because only with more livestock will they become rich.
But as the number of livestock increases, the pasture remains unchanged and is shrinking every year due to desertification. This is a very troublesome place.
The lower reaches of the Maquan River are very good at controlling desertification because of its lower altitude and proximity to the densely populated areas such as Sala and Zhilin.
But as you slowly walk up the Maquan River, the situation becomes complicated.
Because there is no snow water flowing, some river beaches have become dry or narrowed, and the river sand underneath is exposed. When the wind blows, it begins to erode the grass and spread everywhere.
There has never been a good way to solve this problem before. We can only suppress it to a certain extent by spending great efforts to clear the squares, but we have not been able to fundamentally solve the problem.
But this year, things seem to have changed a little.
The leaders came to a section of the river beach and looked at the lush plants growing on the river beach. They stopped the car and looked at it for a long time.
"What kind of plant is this? When was it planted? I remember this time last year, it was all sand, right?"
The leader was obviously very concerned about this matter. He still remembered the scene he saw last year this year, so he noticed the difference as soon as he arrived and asked immediately.
As the general person in charge of desertification control, Luo Ying has been accompanying the leaders on their inspections.
After listening to the leader's question, she quickly stepped forward and explained: "This is the Sophora psomia that we introduced from the northwest last year. It is a very special variety, specially used to control desertification. Although it has not been planted for more than a year, the effect is still there." Very good. Look, leader, this place was originally a river beach. It was covered by ice and snow in winter. When the snow melted, the cold snow water flowed through. No plants could survive. However, these acacias were fine. After the snow water passed, They will grow back, which not only conserves water and soil, but also turns into very good fodder.¡±
The leader walked over to carefully inspect the growth of Sophora japonica. He couldn't help but pick a few leaves, put them in his mouth, and chewed them gently, as if he were a grazing animal, tasting the taste of Sophora japonica. .
After chewing for a while, the leader nodded: "My mother is also a herdsman. My family has raised cattle and sheep since I was a child. This is how my mother raised the five children in our family. When I was very hungry when I was a child, I I often eat their fodder with the cattle and sheep, trying to see if I can fill my stomach like them."
The leader felt a little emotional that the days of poverty in the past were far away from him now, but he still had fresh memories of the scene at that time.
"After a slight pause, he smiled and said: "Because of this, my mouth knows how to taste the quality of forage. These locust trees taste very good, and cattle and sheep should like to eat them."
Luo Ying thinks this statement is quite interesting. Human stomachs cannot digest these forages at all, but through observation, she found that cattle and sheep really like to eat these Sophora japonica.
She tried putting some forage that cattle and sheep particularly like to eat together with the leaves of Sophora japonica. Unexpectedly, most of the cattle and sheep chose Sophora japonica. Through this result of selecting with their feet, it can be seen that cattle and sheep prefer to eat these Sophora japonica. Sophora japonica grows.
The leader pointed to the herdsmen who were working hard to plant Sophora japonica on the river beach and asked: "Are you going to plant all this Sophora japonica here?"
"Yes, everything will be planted from here to there."
Luo Ying pointed to the distance and introduced to the leader: "We planted Sophora acacia on a small scale in this area last year and found that the effect was very good, so this year we bought more of this Sophora acacia and prepared to cover the nearby river beaches. If planted well, the desertification situation in next year¡¯s generation should be able to be curbed.¡±The leader was very happy because he felt that there was some hope of a complete solution to the problem that had been bothering him for a long time.
Most Tibetan families were born as serfs and are not afraid of hardship. They are willing to work hard to protect their pastures. What they are afraid of is that they cannot find a good solution and can only watch their pastures deteriorate. A little bit was swallowed by the wind and sand.
The leader nodded: "Okay, your results should be shared so that more people know where did you buy this Sophora abrasicae?"
Luo Ying explained: "We bought them from a company called Muya Forestry in the northwest. Each plant costs one yuan. This year we bought five million plants."
"One dollar per plant?"
The leader came from a poor family. His father died young and the family relied on his mother¡¯s hard work to raise his brothers and sisters, so he was used to breaking one dollar into several pieces.
Now when he heard that a locust tree cost one yuan, his eyelids immediately jumped up and kept jumping: "Why is it so expensive? I heard that one yuan can buy several saplings in the market. Last time Nandan told me that if we buy in large quantities, we can buy eight bai Lai plants for one dollar."
Luo Ying shook her head after hearing this and explained: "Leader, it's different. Muya Forestry is a very powerful company in desertification control and seedling cultivation. I visited their company in person. This variety of Sophora acacia is what they target. It was developed in the environment of our plateau area and the cost is very high, so that¡¯s why the price is like this.¡±
After a slight pause, Luo Ying added: "Although the price is more expensive than other sandy land plants, the white grass that your leader mentioned does not have such an effect here. We have also planted white grass in the past, but they are in the sandy land." It's okay to plant them, but it won't work if they are placed on the river beach. Every year when the snow passes, they all freeze to death. However, this kind of sand-growing locust tree is not afraid of the freezing snow and can withstand drying out. The most important thing is that the livestock can still survive. It loves to eat, kills three birds with one stone, and is the most suitable desert control plant for us."
Finally, she concluded: "I think this price is not expensive." (Remember the website address: www.hlnovel.com
