In Tibet in June, the ice and snow have melted.
The ground washed by the glacier and snow water has begun to gradually warm up.
At this time, the swelling is relatively cool, and it can even make people feel hot at noon, but 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, the leaders of the Tibetan area will patrol along the Maquan River upstream.
There is no way, after the snow water melts every year, the river beach will become more barren, and the river sand will fly up from the river with the strong wind, causing very serious land desertification.
This matter has attracted the attention of Tibetan leaders, and they have been trying to find ways to control the desertification problem near the Maquan River and protect the grassland.
Grasslands are extremely important to Tibetans.
Tibetan herdsmen have lived by grazing for generations, and their livestock is their wealth. Every herdsman wants to have more livestock, because they will become rich only if they have more livestock.
However, there are more livestock, but the grassland will not change, and because of the problem of desertification, it is shrinking every year. This is a very troublesome place.
In the lower reaches of the Maquan River, desertification control is very good because of its low altitude and proximity to densely populated places such as Sara and Zhilin.
But walking slowly up the Maquan River, the situation becomes complicated.
Because there is no flow of snow water, some river beaches have become dry or narrowed, and the river sand underneath is exposed. When the wind blows, it starts to erode the grassland everywhere and spread in all directions.
There has been no good way to solve this problem before. We can only suppress it to a certain extent by making great efforts to make grass squares, but we can't solve the problem fundamentally.
But this year, things seem to have changed a bit.
The leaders came to a river beach, looked at the lush plants growing on the river beach, stopped the car specially, and checked 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 is obviously very concerned about this matter, and he still remembers what he saw last year, so he saw the difference as soon as he arrived, and immediately asked.
As the general person in charge of sand control, Luo Ying has been accompanying the leaders on inspections.
After listening to the leader's question, she hurried forward to explain: "This is the sand-grown locust tree we introduced from the northwest last year. It is a very special variety, specially used for sand control. Although it has not been planted for a year, the effect is great." Very good. Leader, you see, this place was originally a river beach, covered by ice and snow in winter, and when the snow melted, the cold snow water flowed through, and no plants could survive, but these sand-grown locust trees were fine. After the snow water passed, They grow back, which retains water and soil and makes for a very good forage."
The leader walked over to carefully check the growth of Sophora japonica, and couldn't help but pick off a few leaves, put them in his mouth, and chew them gently, as if he was 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 our five children. When I was very hungry when I was young, I I often eat their forage with cattle and sheep, and I want to see if I can fill my stomach like them."
The leader felt a little emotional, the poor days in the past were far away from him now, but he still had a vivid memory of the scene at that time.
After a slight pause, he smiled again and said, "Because of this, my mouth knows how to taste good or bad forage. These sand-grown locust trees taste very good, and cattle and sheep should like them very much."
Luo Ying thinks this statement is quite interesting. The human stomach cannot digest these forages at all, but through observation, she found that cattle and sheep really like to eat these sandy locust trees.
She tried to put some forage that cattle and sheep especially like to eat together with the leaves of sandy locust tree. Unexpectedly, most of the cattle and sheep chose sandy locust tree. Through the results of this selection, it can be seen that cattle and sheep prefer to eat these sandalwood. Health locust tree.
The leader pointed to the herdsmen who were working hard to plant sand-grown locust trees on the river beach, and asked, "Are you going to plant this sand-grown locust tree here?"
"Yes, from here to there, it will all be planted."
Luo Ying pointed to the distance and introduced to the leader: "We have planted sandy locust trees in this area last year on a small scale and found that the effect is very good, so we bought more of this kind of sandy locust trees this year, and plan to make the nearby river beaches all Plant it well, and next year’s generation of desertification should be curbed.”
The leader was very happy, because he felt that the problem that had troubled him for a long time seemed to see a little hope for a complete solution.
Most Tibetan families are of serf origin 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, so they can only watch their pastures helplessly. A little bit was swallowed by the wind and sand.
The leader nodded: "Okay, your results should be shared, so that more people can know, where did you buy this kind of sandy locust tree?"
Luo Ying explained: "We bought it from a company in Northwest China called Muya Forestry. Each plant costs one yuan. This year we bought five million plants."
"One yuan per plant?"
The leader came from a poor family, his father died early, and the family relied on his mother's hard work to raise their brothers and sisters, so he was used to breaking one dollar into several.
Now when he heard that a sand-grown locust tree cost one yuan, his eyelids jumped immediately, 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 you buy in large quantities, you can buy eight white thorns 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 sand control and seedling cultivation. I went to see their company in person. This variety of sand-grown locust tree is what they target. It was developed in the environment of our plateau area, and the cost is very high, so this is the price."
After a short pause, Luo Ying continued: "Although the price is more expensive than other sand plants, the white thorns you mentioned have no such effect here. We have planted white thorns before, but they grow in the sand. It’s okay to plant them on the river beach. Every year when the snow water passes, they all freeze to death. However, this kind of sand-grown locust tree is not afraid of freezing snow water and can withstand drying up. The most important thing is that the animals are still alive. Love to eat, kill three birds with one stone, it is the most suitable sand control plant for us here."
In the end, she concluded: "I think this price is not expensive."
