Natural ecological environment and cultural and historical factors

(1) Soil topography: The soil type in the Majiahu area of Wuzhong is mainly irrigated and silted soil, with deep soil layers, generally above 1 meter, mostly light and medium loam in texture, high soil maturity, organic matter content generally ranging from 1.3-1.5%, fertile soil, light salinization, good physical and chemical properties, which is conducive to the growth and development of Majiahu watermelons. The use of "two films and one canopy" arch greenhouse cultivation technology can increase ground temperature and promote early maturity of Majiahu watermelons

(2) Hydrological situation: The Yellow River is the main irrigation water source for farmland in Litong District. There are five main canals in the area, namely Qin Canal, Han Canal, Malian Canal, Donggan Canal, and Minsheng Canal. 30 supporting branch canals are distributed vertically and horizontally throughout the entire area, diverting 480 million cubic meters of water from the Yellow River every year. The annual surface runoff is 3.3668 million cubic meters, with good water quality and no human or industrial pollution, making it an ideal water source for industrial, agricultural, production, and domestic use. The Majiahu area in Wuzhong has a flat terrain and is irrigated by the Yellow River's self flowing water. The irrigation is convenient and the water volume is abundant, which can meet the water needs of the Majiahu watermelon during the seedling stage, flowering stage, and fruit expansion stage, ensuring the quality of the fruit. The water quality meets the "Irrigation Water Quality Requirements" stipulated in the "Environmental Conditions for the Production Area of Pollution free Food Majiahu Watermelon" NY5110-2002

(3) Climate situation: The Majiahu area in Wuzhong belongs to the temperate semi-arid climate zone, with an annual precipitation of 260.7 millimeters, an annual evaporation of 2018 millimeters, an average temperature of 9.4 degrees Celsius, an annual sunshine duration of 2884.7-3130.2 hours, a sunshine percentage of 63-69%, an average effective accumulated temperature of 3285 ℃, a temperature difference of 13 ℃ between day and night, a frost free period of 171 days, four distinct seasons, abundant sunshine, strong evaporation, and rare rain and snow. It is one of the areas with the most abundant solar radiation in China. It has the characteristics of late spring warmth, short summer heat, early autumn coolness, and long winter coldness. Beneficial for the growth, development, flowering, and fruiting of Majiahu watermelons, especially during the fruiting period when the daytime temperature can reach 28-35 ℃ and the temperature difference between day and night can reach up to 13 ℃. Lower nighttime temperatures are conducive to the transportation of assimilates from Majiahu watermelons, reducing nutrient consumption by respiration, increasing fruit sugar content, and forming the unique flavor of Majiahu watermelons; Winter is extremely cold and long, which is conducive to killing various soil borne bacteria and overwintering insect eggs in the soil. Chemical pesticides are basically not used, ensuring the quality of Majiahu watermelons
