Natural ecological environment and humanistic and historical factors
(1) Soil and landform conditions: The paddy fields of Chaluhe Characteristic Agricultural Economic Development Zone are distributed in the open plain at the southern end of Songliao Plain, and are connected by Yinma River within the territory. , Chalu River, Aolong River alluvial formation. The soil types are meadow soil, alluvial soil and paddy soil. The soil layer is deep, loose and fertile. The average soil organic matter content is ≥3.34%, total nitrogen content is 0.1535%, total phosphorus content is 0.0944%, and total potassium content is 3.226%. It is rich in trace elements such as silicon, zinc, iron, and selenium. The soil pH value is 6.1-6.42.
(2) Hydrological conditions: The seven rivers in the region, including Yinma River, Chalu River, and Aolong River, are the first-level tributaries of the Second Songhua River system. The annual average precipitation is 650-700 mm, and the precipitation from May to September is 595 mm, accounting for 80% of the annual precipitation. The total annual precipitation is 720 million cubic meters. Over the years, the average runoff of the river
has been maintained at 400 million cubic meters. The total amount of available water resources in the region is 582 million cubic meters (including surface water and groundwater). The water volume is abundant and the flow direction is favorable, making it suitable for large-area green rice cultivation. There are 7 large, medium and small reservoirs in the area, including Xingxingshao Reservoir. Among them, Xingxingshao Reservoir is a large reservoir in the province, with a water collection area of ??845 square kilometers. There are no pollution sources in the upstream. The normal water storage is 116 million cubic meters, and the maximum water storage is 26,500 cubic meters. Ten thousand cubic meters, the irrigation area is 165,000 acres, the flood control protection area is 22,500 acres, and the waterlogging removal area is 15,000 acres, which can guarantee the irrigation water for paddy fields in 5 towns and 55 administrative villages.
(3) Climate conditions: Yongji County has a north temperate continental monsoon climate. The terrain is surrounded by mountains in the southeast and open plains in the northwest, forming a unique microclimate area. The annual average temperature is 4.9℃, the effective accumulated temperature ≥10℃ is 2794℃, the annual sunshine hours are 2500-2800 hours, and the actual sunshine rate is 65%.
During the crop growing season from April to September, the sunshine hours are 1500-1600 hours, and the frost-free period is 138-145 days. From July to August, it is hot and rainy, with rain and heat in the same season, which is conducive to rice growth. The average temperature from August to September from earring to maturity is 22.7°C, and the temperature difference between day and night is large, with an average temperature difference of 11.4°C, which is conducive to the accumulation of rice nutrients. Yongji County has fewer natural disasters such as floods and early frosts, cold winters, and relatively few pests and diseases that threaten rice production.
(4) Humanistic and historical situation: Rice cultivation in the Chaluhe Characteristic Agricultural Economic Zone of Yongji County has a history of 150 years. According to the "Yongji County Chronicle": "During the Kangxi period of the Qing Dynasty, this area used to be a pasture for raising military horses, called Ximacang. After years of reclamation, it gradually became cultivated land, mainly planting sorghum, barnyard grass, japonica rice and other flood-resistant crops, especially Japonica rice is famous throughout the province. There is a folk saying that "Chaluhe Japonica rice can be cooked three times without changing the taste and the rice grains will not break. It is called the top three water."
In 1903 (the 29th year of Guangxu), a large number of Korean farmers moved into the areas along the Yinma River, Chalu River, and Aolong River, and used the natural resources together with the local Han, Manchu, Hui and other ethnic groups. rivers, build willow barrages, and expand the scale of paddy field planting. In 1927 (the 16th year of the Republic of China), Wang Guangshen, Liu Hui and other large farmers built embankments of 3,000 meters on the east bank of the Yinma River and the north bank of the Chalu River. The embankments were 1.5 meters high to control floods, cut off the rivers and dig drainage ditches 2-3 Kilometers, waterlogging was controlled, low-lying dry fields were converted into paddy fields, and continuous planting was concentrated, greatly increasing the rice planting area. By 1944, the area of ??paddy fields had reached 143,000 acres.
In the 1970s, the Xingxingshao Reservoir was fully completed, which promoted the rapid development of local rice production. The paddy field area expanded to 15,000 hectares, and it became a national commercial grain base county. In 2003, it was confirmed by the Green Industry Committee of the China Investment and Technology Promotion Office of the United Nations Industrial Development Organization that the Chaluhe Agricultural Economic Demonstration Zone in Yongji County was a green industrial park; in 2006, it was confirmed by the China Green Food Development Center and the China Green Food Association
Yongji County of Jilin Province is a "Green Agriculture Demonstration Zone Construction Unit"; in 2007, it was approved by the Green Food Management Office of the Ministry of Agriculture and the China Green Food Development Center as a "National Green Food Raw Material (Rice)" ) standardized production base".
In 150 years of rice planting practice, Yongji rice farmers have developed a set of scientific and advanced "shallow-moistening (sun)-shallow" intermittent irrigation technology; the excellent rice variety "Shuangfeng" cultivated by Yongji rice researchers 8", with its characteristics of disease resistance, cold resistance, early maturity and good yield, it has been demonstrated and promoted throughout the province since the 1970s, and has become the first choice for early maturing varieties among rice farmers in the province; the Jilin Province local standard compiled by it "Technical Regulations for Comprehensive Cultivation of Rice in Bowl Raising and Thin Planting" (DB22/T848-1996) has become the technical standard guiding rice planting in our province; the county agricultural science station's original greenhouse dry breeding technology and greenhouse tray seedling machine transplanting technology have improved the average yield per mu. From 466 kilograms to 1,000 kilograms today, it won the National Science and Technology Commission Agricultural Technology Promotion Award and the Provincial Scientific Research Achievement Award.
