natural condition

The whole site belongs to the proluvial inclined plain area in front of the eastern foot of Helan Mountain. The terrain is high in the West and low in the East, with an altitude of 1106-1407m. the climate is a typical dry continental climate in the middle temperate zone, which is characterized by drought, less rain, sufficient sunshine, strong evaporation, strong wind and sand, large temperature difference between day and night, and often accompanied by natural disasters such as frost, dry hot wind, hail, mountain torrents and so on. The annual average precipitation is 187 mm, with great interannual variation. The annual precipitation is mainly concentrated in July, August and September, accounting for 65% of the annual precipitation. The annual evaporation is 1250 mm, which is 6 times of the precipitation; the annual average temperature is 8.5 ℃, the extreme maximum temperature is 39.3 ℃, the extreme minimum temperature is - 30.6 ℃; the annual sunshine hours are 2800-3300 hours; the frost free period is about 155 days; the southeast wind is more in summer, the northwest wind is more in winter, the wind force is 6-7, the annual average wind speed is 2.9 M / S; the soil freezing depth is 0.8-1.2 m, and the freezing period is about 150 days.

resources

Surface water: the precipitation in the farm is scarce, the surface water data is very poor, the average annual runoff depth is less than 5mm, and there is basically no available surface water data. groundwater: the groundwater resources are relatively rich, with a buried depth of 9.6m. The main recharge sources are irrigation infiltration, precipitation and lateral recharge in front of Helan Mountain. The recharge modulus is 107000m / KMY, the groundwater salinity is 900MG / L, and the total content of various soluble salts and sodium salts are less. It is suitable for irrigation, and long-term irrigation has no adverse effect on crop growth. irrigation water from the Yellow River: the West Main Canal flows through the east edge of the farm, which belongs to the pumping irrigation area of the west main canal. The current annual pumping water volume is 45.9 million cubic meters, and the pumping irrigation area is 3600 hectares. soil, vegetation the soil types are mainly calcareous soil and aeolian sandy soil, and the surface soil is mostly sandy loam. The content of soil natural fertility is lower than medium, and the soil thickness is deeper, mostly more than 5 meters. The surface soil is light, and the phenomenon of water leakage and fertilizer leakage is serious during flood irrigation. Most of the existing cultivated land belongs to medium and low yield field, because of poor drainage, soil salinization phenomenon. The vegetation degree of natural forest and grass is less than 7%, and the vegetation mainly includes artificial protection forest, economic forest and crops.

socioeconomic

Administrative division and population Huangyangtan farm is a state-owned farm under the administration of agricultural reclamation of the autonomous region. In 2010, the total population was 3984 (2010), and the natural growth rate of population was 6.3 ‰. 2. Land use land resources are abundant, with a total area of 66.4 square kilometers (land composition is shown in the table below), mainly composed of calcareous soil and aeolian sandy soil. (1) unreasonable land use structure, small proportion of forest land, large proportion of pasture land, resulting in poor water and soil conservation, serious soil desertification and soil erosion in some areas, and damage to ecological balance. (2) drought and water shortage restrict the development of unused land. (3) the village settlements are scattered, the per capita residential land is large, and the phenomenon of unauthorized occupation and construction is prominent. 3, economic development level Huangyangtan farm is mainly agricultural, mainly planting wheat, corn and other food crops, economic crops are grapes, sunflower, etc., the annual industrial output value is only 170000 yuan; farm income mainly comes from crops, in 2009, the total industrial and agricultural output value of the whole farm is 64.61 million yuan, the average income of workers is 12313 yuan, and the per capita income of the farm is 7335 yuan. On the whole, the output value of the secondary and tertiary industries of the farm has a small proportion and a weak foundation, but the per capita annual income is relatively high and the living standard of the masses is relatively good. 4. Main industries and products (1) agriculture Huangyangtan farm is beneficial to the growth of various crops due to the benefits of the Yellow River, sufficient sunshine and large temperature difference between day and night. The farm is dominated by planting, supplemented by breeding, in which grape, wheat and corn are the main planting industries. In 2009, the total planting area was 41930 mu, including 26000 mu of grapes and 15930 mu of grain crops, with a total grain output of 10300 tons. The breeding industry takes the household as the unit to breed separately. There are 13000 poultry, 860 cattle, 680 sheep and 850 pigs. (2) the Ministry of industry has two liquor making enterprises without large-scale processing enterprises.

facilities

Main infrastructure and public service facilities of the site 1. Irrigation works. Huangyangtan farm has 4 main canals with a total length of 6.63 km and 7 branch canals with a total length of 36 km. The main water pumping canal is located in the second and third branch canal sections of Huangyangtan water pumping irrigation area, where there are four stages of water pumping, with a total head of 58 meters and supporting power of 2195 kW. The lining rate of canal system is low, field irrigation, irrigation water utilization coefficient is about 0.4, and the water supply is insufficient during the irrigation peak, which can not guarantee the irrigation. 2. Drainage works. Although there is open ditch drainage system in the pumping irrigation area of the farm, due to the influence of the West Main Canal and Baotou Lanzhou railway, some ditches can not be unblocked and the drainage efficiency is poor, resulting in some soil salinization, and two thirds of the cultivated land is medium and low yield land. (3) flood control works. The farm is close to Helan Mountain, the cross section of shanhonggou is small, the confluence is fast, but the total amount of flood is small. There is a flood storage area in the north of the fourth team of the farm. 4. The farm has good traffic conditions. Baotou Lanzhou railway passes through the east of the site and Huangyangtan station is set in the southeast corner of the site; Yanshan highway (G110) passes through the west of the site and has convenient connection with the site; yonghuang highway passes through the site, with a total length of about 6.5km; Yinhuang highway runs through the site from north to South and connects the site and yinba highway, which is the main road for farm residents to the urban area of Yinchuan The production road is unblocked, with a width of 3-5M. It is connected with Yinhuang highway, yonghuang highway and National Highway 110, and can be used for large machinery. At present, Huangyangtan farm has 186 sets of agricultural machinery, including 11 combine harvesters, 21 bulldozers and 10 planters. According to the needs of local agricultural production, the farm Department has set up agricultural machinery service station. 6. There is a substation in the northeast corner of the station Huangyangtan farm substation (110KV, main transformer capacity 150MVA). The 10kV line has been connected to the station Department and all agricultural production teams. One telecom company, with an installed capacity of 2500 phones, has 1700 users. The base stations of China Mobile and China Unicom cover the field, so the communication is very convenient. Cable TV network covers the whole field. 7. There is a primary school with 35 teaching staff and 467 students in the Department. There is a hospital with 14 medical staff and 25 beds.
