[Explanation] In winter in Ruoergai County, Aba Prefecture, Sichuan Province, mountains, rivers, and grasslands are covered with snow, which is like a pure and charming natural picture.

But for the livestock in the alpine pastoral areas, now is the "catastrophic" period of forage shortage that must be experienced every year.

　　In Xiangdong Village, Dazarsi Town, Ruoergai County, close to the Yellow River, villager Zewang Ruodan is checking the growth of lambs on the pasture.

In 2020, Zewang Ruodan first came into contact with the three-combination homeopathic breeding integration technology (hereinafter referred to as the "three-combination" technology), which is based on proper grazing, scientific supplementary feeding, and captive breeding in winter and spring, which not only reduced the fat loss rate and mortality of cattle and sheep. rate, but also relieve the pressure on the pasture.

　　In the previous year, when the death rate (rate) was the highest (high), more than 300 sheep died, more than 200 sheep died in the second year, and less in the third year, only more than 100 sheep died.

Later (at the beginning) I supplemented very little feed, and I added a little later (on the original basis), and the latter project would be good.

According to this, we now have fewer livestock, so we protect the pastures.

Now our pastures are in good shape, and the number of livestock has also decreased, and the fatness of the livestock has also increased (increased).

　　[Explanation] Rojan Nimei, who also uses the "three-combination" technology for breeding, introduced that cattle and sheep are the "lifeblood" of plateau herdsmen.

In the past, the number of livestock increased with the growth of the population, but the grassland area and forage yield were constant, which made the "contradiction" between grassland and animal husbandry expand day by day.

Using the "three-in-one" technology, although the livestock breeding volume of the herdsmen has decreased overall, their income has not decreased.

The demand for pastures for raising livestock has also been reduced from the original 25 mu of pastures to raise one yak to 10 mu of pastures to raise one yak.

The concept of sustainable development has also quietly "taken root" in the hearts of herdsmen.

　　In the past, the desertification of the pasture was serious, and there was little rain in the past. In this pasture, you (the livestock) had eaten up the grass everywhere, and the grass had been eaten up, and there was no place for the livestock, and the mortality rate of the livestock was also high.

If the grass and livestock are balanced like this, just like this pasture, there is still hay in April and May, and if there is still hay, the water storage capacity of the pasture is better.

　　[Explanation] Today, ecological protection and high-quality development in the Yellow River Basin are an important part of ecosystem protection and governance in Sichuan Province.

According to Bai Shiqi, chief engineer of the Sichuan Forestry and Grassland Bureau, the core issue of ecological protection and high-quality development of the Yellow River Basin in Sichuan is the governance and utilization of grasslands.

　　I think grassland governance is a comprehensive social and economic development issue.

We must combine the farmers and herdsmen's living issues and livelihood issues with our ecological issues. It is better to take into account the pain points of all parties.

　　[Explanation] It is reported that Ruoergai County is one of the top ten major animal husbandry counties in Sichuan Province. The county has 12.1263 million mu of natural grassland, of which 9.78 million mu of grassland can be used.

Bai Shijie pointed out that "increasing grass" is a reliable way to relieve pressure on grassland and reduce grassland degradation.

　　From the perspective of international practice, it is appropriate to use 10% of the grassland area to grow pasture, which is suitable for planting artificial grassland.

(From) what we know so far, our entire Qinghai-Tibet Plateau and our western Sichuan Plateau, (artificial grassland planting) may be around 2%.

After years of research at the Sichuan Academy of Grassland, we have done a lot of scientific experiments in the core areas of the upper reaches of the Yellow River such as Hongyuan and Ruoergai. In fact, our high-yield semi-artificial grassland and no-till grassland can be formed, so it is It is said (use) about 10% to make artificial grassland, and (can) exchange 90% of the grazing pressure (natural grassland safety).
