1、 Set up a desert mechanization control corps

（1） The regiment is composed of 26 mechanized teams; 475 sets of various large machinery for each unit; A large desert control team equipped with 12350 mechanical equipment has been formed. The area of deserts treated every year is more than 110000 square kilometers.

（2） Staffing of the Legion: 18545

1. Corps headquarters: 85 people

2. The total number of staff of 26 units: 18460 (including 710 staff of each unit)

3. The 26 teams put into desert control at the same time, which can eliminate 670000 square kilometers of desert sand on China's territory within 6 years. (1011 million mu)

2、 Ask for good farmland from China's desert

（1） China's vast desert is the foundation for the expansion of arable land.

1. Overview of desert and sandy land in China

(1) There are 12 desert sandy lands distributed in Inner Mongolia, Qinghai, Xinjiang and other places in China:

① Taklimakan Desert 337600 Km2 ② Gurbantunggut Desert 48800 Km2

③ 19500 Km2 of Kumtag Desert ④ 34900 Km2 of Qaidam Basin Desert

⑤ 44300 Km2 in Badain Jilin Desert ⑥ 42700 Km2 in Tengger Desert

⑦ Ulanbuhe Desert 11500 Km2 ⑧ Kubuqi Desert 18600 Km2

⑨ 23800 Km2 in Hunshandak sandy land ⑩ 50600 Km2 in Horqin sandy land

⑪ 32100 Km2 in Maowusu sandy land and 10000 Km2 in Hulunbeier sandy land

(2) Among them, the total area of desert is 557900 Km2, and the total area of sandy land is 116500 Km2.

(3) The total area of desert and sandy land is 674400 Km2 (1011.6 million mu).

(4) Overview after the application of desert sand mechanization treatment:

① In six years, 674400 square kilometers of desert sand on China's territory can be eliminated in a large area.

② The eliminated desert sand can produce 300 million mu of good farmland by 30%. After our treatment, 95% of the area will be green, which will completely change the ecological landscape of the sand area.

2. A brief introduction to the method of how desert sand is transformed into cultivated land by applying the mechanized elimination method of desert sand.

(1) Sand consolidation: use bulldozers to level the sand.

(2) Composite mud spraying:

① Mud composition: clay, farmyard manure, biogas water, biological fertilizer, sand to soil biological agent.

② Mud spraying: twice, 5m3 each time. The mud should be thinner for the first time to facilitate the rapid infiltration of the fertile water into the sand. The second mud is slightly thicker than the first.

(3) Turn on the rotary tiller: after each mud spraying, turn on the rotary tiller to turn the sprayed sand once.

(4) Planting crops: After rotary tillage, the sand will be turned into loam and good farmland after the biological agent of sand-to-soil changes effect one year.

（2） For example, the three major deserts and sandy lands in the Yanhe River basin have become fertile fields after mechanized treatment.

1. Relevant data of the three desert sandy lands turned into fertile fields after mechanized treatment.

(1) The Kubuqi Desert has become a fertile land of up to 60%, and 18600 km2 (27.9 million mu) has become a fertile land of 16.74 million mu.

Including: 70% of spring wheat land, 16.74 million mu × 0.7=1718000 mu; Miscellaneous grain land: planting 30% of soybeans, mung beans and millet, 16.74 million mu × 0.3=5.022 million mu.

(2) The Ulanbuhe Desert can be turned into fertile land up to 50%, 11500 km2 (17.25 million mu) and 8.625 million mu.

Including: 65% of spring wheat land, 8.625 million mu × 0.65=5606250 mu; 35% of coarse grain land, 6.825 million mu × 0.35=30187500 mu (planting: mung beans, adzuki beans, lentils, cereals).

(3) Maowusu sandy land can be turned into fertile land up to 35%, 32100 km2 (48.15 million mu) and 16.8525 million mu.

Including: 60% of spring wheat field, 16.8525 million mu × 0.6=1011500 mu; 40% of coarse grain land, 16.8525 million mu × 0.4=6.741 million mu (planting: mung bean, adzuki bean, lentil, arbor and cereal).

2. Relevant data of the three major deserts and deserts after mechanized treatment.

(1) Total area of the three major deserts: 62200 km2 (93.3 million mu)

(2) After treatment, the three desert sandy lands can become fertile fields with a total area of 42.2175 million mu. 16.74 million mu+8625 million mu+101115 million mu=42.2175 million mu

(3) Including:

① The total area for planting spring wheat is 274357500 mu

11.718 million mu+5.06625 million mu+1.0115 million mu=27.43575 million mu

Total annual yield of wheat: 500kg/mu × 274357500 mu=17.3178 million tons

② The total area for planting coarse grains is 147817500 mu

502200 mu+30187500 mu+6741 mu=1478175 mu

Annual output of various miscellaneous grains: 160kg/mu × 147817500 mu=2365000 tons.

(4) The total output of various grains in the three major deserts and deserts is: 16.0828 million tons

13.7178 million tons+23.65 million tons=16.0828 million tons.

(5) The estimated economic effects of the three desert sand fields: 43760500 yuan in total.

① Wheat: 2.5 yuan/kg × 13.7178 million tons=34294.5 million yuan

② Miscellaneous grain: 4 yuan/kg × 2.365 million tons=9466 million yuan (9.466 billion yuan)

(6) The total number of cultivators required for the fertile land produced by the three desert sandy lands is 5066100.

① The total number of cultivators required: 120 people/10000 mu × 42.2175 million mu=50661 million people,

② Total annual salary of cultivators: 60000 yuan/year/person × 506.61 million people=30.3966 billion yuan.

3. The annual financial effect of the fertile fields produced by the three desert sandy lands is estimated.

(1) The total area of fertile land is 42.2175 million mu, with an annual output value of 43.760.5 billion yuan.

(2) The cultivation cost of 42.2175 million mu: 40.95095 billion yuan.

① Ecological fertilizer: 120 yuan/mu × 4.2275 million mu=5.0661 billion yuan.

② Farming cost: 30 yuan/mu × 4.2275 million mu=1266.5 billion yuan.

③ The total wage of farming personnel is 30.3996 billion yuan.

④ Other expenses: 100 yuan/mu × 4.2275 million mu=4.22175 billion yuan.

(3) The annual profit of 42.2175 million mu is: 2.80955 billion yuan.

The annual output value is 43.760.5 billion yuan - the total farming cost is 40.95095 billion yuan=28095.5 billion yuan.

3、 Grain effect and economic effect produced by desert fertile fields

（1） After all the 12 deserts in China are harnessed, 300 million mu (300 million mu) of arable land will be produced, including 50% of cultivable wheat grain and miscellaneous grain (soybeans, mung beans, black beans, adzuki beans, joe wheat, and millet), and 150 million mu (150 million mu) of cultivated grain.

（2） 300 million mu of arable land, estimated annual grain output. Calculated by * low yield: 84 million tons.

1. Total output of wheat grain: 400kg/mu x 150 million mu=60 million tons

2. Total output of wheat grain: 160kg/mu x 150 million mu=24 million tons

（3） 300 million mu of cultivated land, estimated annual output value: 246 billion yuan

1. Wheat: 2.5 yuan/kg × 60 million tons=150 billion yuan

2. Miscellaneous grains: 4 yuan/kg x 24 million tons=96 billion yuan

（4） Cultivation cost of 300 million mu of cultivated land: 240 billion yuan

1. Biological fertilizer: 120 yuan/mu x 300 million mu=36 billion yuan

2. Cultivation cost: 30 yuan/mu x 300 million mu=9 billion yuan

3. Farmer wages: 180 billion yuan

4. Other expenses: 50 yuan/mu x 300 million mu=15 billion yuan

（5） Annual profit of 300 million mu: 6 billion yuan

Annual output value: 246 billion yuan - cultivation cost 240 billion yuan=6 billion yuan

（6） Total construction investment of 300 million mu: 420 billion yuan
