Ordos City in western Inner Mongolia is located in the hinterland of the Mu Us Sandy Land and the Kubuqi Desert. In September 2017, the 13th Conference of the Parties to the United Nations Convention to Combat Desertification and non-governmental organization personnel conducted a special inspection in Ordos City. They learned that the control rate of the Mu Us sandy land in the city was close to 80%. When the desert has become very difficult, Babu, Executive Secretary of the Convention Secretariat, sighed: "It is a miracle in the history of sand control in China and the world."

Since the beginning of this year, in the face of the adverse impact of the new crown pneumonia epidemic, the local area has actively promoted the upgrading of the ecological industry in the desert area, guided and supported the extension of the animal husbandry resource-based industry chain, actively developed the grass resource-based industry, enlarged and strengthened the scale of the green industry, and gradually built an efficient , A clean, low-carbon, and recycling sandy grassland green development industrial system.

Inner Mongolia is an important animal husbandry base in the country. For a long time, grassland animal husbandry products have been regarded as a symbol of green ecological products. The development of animal husbandry relies on a large number of high-quality forage grasss produced in natural forage grasss. However, in recent years, the output of grassland forage grasss has become increasingly difficult to meet the development needs of grassland animal husbandry, and the shortage of forage grass resources has become a constraint on the development of animal husbandry.

Among the 1.3 billion acres of grassland in Inner Mongolia, there are 500 million acres of deserted grassland (also known as sandy forage grass), accounting for 38.5% of the grassland area. Desertified grassland is a weak part of the grassland ecosystem, and protecting desertified grassland is an important task for green development in sandy areas. The organic combination of grassland protection and ecological construction results has become an important path for grassland development in sandy areas.

Animal husbandry is a traditional advantageous industry in Inner Mongolia. There are natural contradictions between protecting grassland, restoring grassland ecology and developing animal husbandry. Alleviate the pressure of animal husbandry on grassland ecology and force the local area to vigorously adjust the product structure and ecological structure of animal husbandry.

The desert is ecologically fragile, but the shrub resources are abundant. Take Caragana korshinskii as an example, the area of ​​Caragana korshinskii in the sandy area of ​​Inner Mongolia exceeds 120 million mu, of which 30 million mu is artificially planted. Relying on shrub resources, Inner Mongolia has integrated scientific and technological advantage resources, strengthened innovative support for the development of animal husbandry, and effectively solved the problem of insufficient grass and fodder.

The shrubs and sub-shrubs such as Caragana korshinskii and Salix psammophila in the northern sandy areas grow rapidly, with dense branches and leaves, well-developed root systems, and strong germination. They are excellent plants for preventing wind and sand, conserving water and soil, and preventing soil desertification. These shrub resources are also an excellent source of forage for ruminant livestock.

Researchers in Inner Mongolia studied the nutrient composition of 5 kinds of sand shrubs in different years and different seasons, and compared them with the nutrient contents of 12 traditional feeds in the Ulan Buh Sand area. The results showed that the nutrient contents of 5 sand shrubs It is rich in amino acids and some indexes are higher than alfalfa, astragalus, corn stover and wheat stover, which is suitable for livestock feeding requirements. The main nutrient content of different shrubs or the same shrub has significant differences in different years and different seasons. This provides guidelines for finding the best harvest time for shrub feed in sandy areas.

The widespread use of woody feed has strongly promoted the development of animal husbandry. As of the end of 2019, the number of livestock in the Inner Mongolia Autonomous Region was 71.924 million heads (only), and the total annual meat output was 2.646 million tons. The number of large livestock raised accounted for 8.5% of the country’s large livestock, and the number of sheep raised accounted for 20% of the country’s total number of animals raised; beef production accounted for 9.4% of the country’s total; mutton production accounted for 22.1% of the country’s total; milk production accounted for 5.529 million tons, accounting for the country’s total 18.2%. The production of large livestock and sheep and the production of milk, meat, wool and cashmere rank first in the country.

The traditional grassland feeding model is unsustainable. How to build a herbivorous forage supply system based on natural grassland and supplemented by feed has become an urgent problem for the grassland ecological industry. Emphasizing the development of food-saving animal husbandry, increasing the use of shrub fodder, and developing food-saving, herbivorous animal husbandry are practical ways.

In order to speed up the development of animal husbandry in the desert areas of Inner Mongolia, the Inner Mongolia Desert Control Association took plant protein feeds to replace protein feed grains as an entry point, organized and coordinated relevant scientific research units and production enterprises in the autonomous region, and used the deserts and sandy land for livestock to feed. Shrubs, Salix psammophila and other shrubs will be transformed and utilized without grain forage, and efforts will be made to promote the construction of a green ecological industrial cycle chain in sandy areas.

Bigger and stronger ecological industry in sandy areas

The green eco-industry cycle chain in the sandy area has been continuously improved, but the ecological industry in the sandy area needs to be strengthened from four aspects.

One is to do a good job in the promotion of shrubs for feed instead of grain for feed. Leguminous sandy shrubs have the characteristics of high protein content, strong adaptability, fast growth, and easy harvesting. They are ideal plant protein resources. According to statistics, only the existing leguminous Caragana korshinskii (Caragana leguminosa) in Inner Mongolia requires an annual output of more than 40 million tons of Caragana korshinskii, and the crude protein content (growth period) is calculated at 15%. , Equivalent to 17 million tons of soybean crude protein content. Inner Mongolia is particularly suitable for the establishment of animal feed pellet production lines and biomass pellet production line. The raw materials are alfalfa, astragalus sativa, willow, cypress, elm, spruce, caragana, clove, corn stalk and wheat stalk, which are suitable for livestock breeding requirements.

According to customs data, my country's soybean imports have been around 90 million tons in the past three years. The main importing countries are Brazil, the United States and Argentina. With the spread of overseas epidemics in Brazil and the United States and increased uncertainty in the external market, shrub protein resources such as Caragana korshinskii can be vigorously developed as food substitutes.

At present, the development and utilization of sandy shrubs in China is still insufficient, and only a few research units have done more in-depth research on nutrients and nutritional value. Extensive planting, collection, processing and utilization of shrubs with fodder value in the sandy leguminous shrubs, replacing the research results of feed grain, is a new way for my country to solve the problem of food and animal husbandry development. The government should formulate active support policies and make every effort Support the development of this cause.

The second is to improve policy support for the green ecological breeding industry chain. At the beginning of the "14th Five-Year Plan", domestic demand for corn and soybeans, which are mainly used as livestock feed, will further increase. In order to effectively solve the problem of insufficient crude protein content in livestock forages, it is necessary to increase the research and exploration of the ways and ways of shrub raw materials for raising cattle, sheep and other livestock, forming a sandy area Caragana korshinskii planting-shrub stubble-feed production-livestock raising -Supporting policies for the development of the green ecological aquaculture industry chain for the production of organic fertilizers and returning to the fields

The third is to increase support for standardized construction of shrubs in sandy areas. The material basis for the construction of beef cattle and sheep breeding bases is the result of ecological construction in the desert area. At present, in the construction of demonstration bases for raising beef cattle and sheep using Caragana korshinskii in the eastern, central and western regions of Inner Mongolia, such as Chifeng, Ordos, and Ulanchabu, the Inner Mongolia Association for Desert Control has obvious concentration of shrub planting area and planting varieties in sandy areas. , Uneven growth conditions, etc., do not meet the needs of large-scale production, and should continue to increase standardized planting management of shrubs.

The fourth is to increase the scale of ecological investment in sandy areas. During the "14th Five-Year Plan" period, it is necessary to solve the problem of low investment in project planning such as the control of the source of sandstorms in Beijing and Tianjin, the protection of natural forest resources, and the construction of the Three North Shelterbelt system. The issue of afforestation cost gap. Further explore the subsidy mechanism for the comprehensive utilization of sandy biological resources such as subsidies for subsidies, construction first and supplement later, actively explore the establishment of a third-party ecological management model for sand areas, organize and formulate ecological public welfare raising, state-owned financial capital, and social capital to enter ecological protection and sand Policies and measures for the construction of district animal husbandry.
