1 Introduction

Yucheng city is located in the alluvial plain of the Yellow River in the northwest of Shandong province. Yucheng got its name from Dayu. According to legend, Dayu was one of the earliest tribal leaders of the Chinese people and tamed the flood in today??s Yucheng. It is also an area for Chinese scientists to demonstrate their evolving technologies to treat poor soils on a large scale. Since the 1950s, the Chinese Academy of Sciences and the Chinese Academy of Agricultural Sciences have developed high-standard farmland in the entire area of Yucheng through sand and alkali control, agricultural development, and water-saving irrigation. Fangsi town of Yucheng is located at the golden zone nearby 37??N . It is moist but not wet in summer and dry but not parch in winter. Therefore, it has superior conditions for twice cropping of winter wheat and summer maize. Double cropping of wheat and grain is the typical cropping mode of Fangsi in Yucheng. This study comparatively analyzes the multiple datasets of physical geography, crop varieties, cultivation management, and history of the Yucheng wheat-grain double-ripening Fangsi irrigation area, and explores the collaborative relationship between environmental protection and sustainable development in the case area, aiming to provide a feasible case for the compelling connection between ecological civilization construction and rural revitalization in Yucheng.

2 Metadata of the Dataset

The metadata of the Wheat-maize double cropping field in Yellow River Irrigation Fangsi Town case dataset on environment protection and sustainable development^[1] is summarized in Table 1. It includes the dataset full name, short name, authors, year of the dataset, temporal resolution, spatial resolution, data format, data size, data files, data publisher, and data sharing policy, etc.

3 Geographical Scope of the Case Area

The case study area is located at Fangsi town. Fangsi is a town under the jurisdiction of Yucheng, Dezhou city (prefecture), Shandong province, with an area of 146.24 km². Fangsi town has 11 communities and 123 administrative villages. The geographical scope is the farmland of wheat-maize in Fangsi town, with a total area of 63.96 km² (Figure 1, 2).

4 Ecological and Geographical Environment

The case area is located in the alluvial plain in the middle and lower reaches of the Yellow River, which is classified as the warm temperate semi-humid monsoon climate area and is a typical alluvial plain. The parent material for soil formation is Yellow River alluvial and sediment. The soil surface texture is mostly medium loam, and the soil layer is deep and easy to cultivate^[3]. Soil pH is generally neutral or slightly alkaline and rich in nutrients, such as nitrogen, phosphorus, and potassium. The case area is a yellow-diversion irrigation area located in the second largest irrigation sector in the lower reaches of the Yellow River.

Table 1  Metadata summary of Wheat-maize double cropping field in Yellow River Irrigation Fangsi Town case dataset on environment protection and sustainable development^[1]

4.1 Climatic Conditions

Yucheng is in a warm-temperate semi-humid continental monsoon climate zone, where there is plenty of heat and light, as well as simultaneous rain and heat, which makes it ideal for agriculture. The average temperature in this region is 13.1 ??C, and the average precipitation is about 567 mm (1,144.4 mm in wet years and 238 mm in dry years).

Precipitation shows a clear seasonal pattern with most precipitation occurring in summer (65 % of the total per year), and less in the winter and spring (20 % of the total per year)^[4]. According to Fangsi town??s meteorological data for the past 30 years (provided by Yucheng Meteorological Bureau), monthly meteorological data for the past 30 years in the case area are shown in Figure 3-6. During the wheat flowering and maturity period (April to June), the average temperature in the case area over the past 30 years is 20.36 ??C, and the average daily temperature range is from 11.3 to 11.6 ??C. It is beneficial for wheat grains to improving the protein content as well as to extending dough stability times^[4], which are favorable for the production of high-quality wheat.

4.2 Soil Physic-Chemical Properties

The soil type of Fangsi town is brown soil, which is medium loam and sandy loam^[3]. Soil samples from two layers were collected in this study. Cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb), zinc (Zn), and copper (Cu) content (mg/kg), and pH were measured by the Physicochemical Analysis Center of the Institute of Geographic Sciences and Resources, Chinese Academy of Sciences. The soil samples showed no detectable cadmium (Cd), with the detection of chromium (Cr) in the range of 69.8 to 88.6 mg/kg, nickel (Ni) in the range of 38.7 to 48.2 mg/kg, lead (Pb) in the range of 41.8 to 50.2 mg/kg, zinc (Zn) in the range of 32.2 to 63.0 mg/kg, and copper (Cu) in the range of 22.6 to 25.9 mg/kg. The detection of pH was near neutral and was good for soil microorganisms (Table 2). Sampling tests revealed a good soil environment, and the heavy metal content is far lower than the pollution risk screening value and risk control value designated by the National agricultural soil standard.

Table 2  Soil pH and heavy metals of the case area

4.3 Water Quality

Surface water and groundwater samples were collected from Fangsi town and its surrounding areas.

The chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), and lead (Pb) concentration (mg/L) and pH for aqueous environment in the case area were determined by the Physicochemical Analysis Center of Institute of Geographic Sciences and Resources of the Chinese Academy of Sciences (Table 3, 4). Samples showed that the pH of surface water and groundwater and the content of heavy metals in Fangsi Town meet the National Class I standards of surface water and groundwater.

The wheat quality data are shown in Table 5. Jimai 44 has a grain bulk density of 788.9 g/L, a grain protein content of 15.4% in grains, a wet gluten content of 35.1%, and a stabilization time of 25.4 minutes. Shiluan 02-1 has a grain bulk density of 820 g/L, a protein content of 17%-18% in grains, 41% in wet gluten and a stabilization time of more than 20 minutes.

Wheat quality of Fangsi town exceeded National standard GB/T 17892??1999, achieving the first grade of wheat and strong gluten wheat. In a horizontal comparison, it is evident that Fangsi town produces superior wheat compared to those planted in other origins. Pull-breaking force is significantly correlated with crude protein content of wheat flour and stability time, which is the key index for the sensory evaluation of cooked wheaten food^[6]. The wheat varieties in the case area have high protein content and long stabilization time, indicating that they have superior characteristics.

The data of maize variety Denghai 605 in Fangsi town is shown in Table 6. The grain bulk density of grain is 766 g/L, exceeding national maize standard (Class I); the crude protein content is 9.35%, crude fat content is 3.76%, crude starch content is 73.40%, lysine content is 0.31%, which are higher than that of maize products from other origins.

Aided by Yucheng Agricultural Chamber of Commerce, Maixiangyuan improved its links with local farmers, provided them with unified wheat seeds and standardized field techniques, promoted the large-scale wheat cultivation and uplifted the quality of wheat. Maixiangyuan also cooperated with the Chinese Academy of Sciences to establish a brand staple grain R&D base to enhance the brand value of wheat products.

6.2 History of Land Use

6.2.1 The History of Special Wheat Cultivation

As early as 2000, Shandong conducted the land zoning for special wheat and classified Dezhou into the most suitable area for special wheat^[10,11]. In 2009, the national wheat zoning by the Ministry of Agriculture included five high-quality wheat producing areas, of which Dezhou (Prefecture) is one of the most suitable areas for high-quality strong gluten and medium gluten wheat. Dezhou further detailed the main production areas of special wheat to county-level bases, such as Wucheng, Pingyuan, Qihe, and Yucheng. Wheat is No.1 crop in Yucheng. Normally, the sowing area is 49,000 ha and the yield is 395,000 tons. Yucheng was awarded the ??National Super Grain-Producing County??^[4]. Yucheng encourages high-quality wheat processing industry. At present, there are large grain enterprises such as Yufei Flour, Zhanyue Food and Dezhou Jinbo. In 2019, the Guidelines for Grain Industry and Rural Revitalization was published.

6.2.2 Improvement of Saline-Alkali Soil in Yucheng

Before 1960, the proportion of poor soil in Yucheng was as high as 43%, mainly saline and alkali soil. Since the 1960s, scientists from the Chinese Academy of Sciences (CAS), have started the research on the improvement of saline alkali soil in the lower reaches of the Yellow River, and set up research bases. By the late 1980s, large scale (667 ha) saline alkali soil improvement demonstration fields had been established.

Meanwhile, the research base in Yucheng was developed into Yucheng Experimental Station of Chinese Academy of Sciences in 1979, run by the Institute of Geography of Chinese Academy of Sciences (CAS). Over the past 40 years, based on the Station, CAS has developed a number of technical systems to meet the needs in different agricultural stages. For example, ??Well Irrigation and Well Drainage?? technology for salt and alkali soil improvement in 1960s; ??Well, Ditch, Leveling, Fertilizer, and Forest?? technology for salt and alkali soil improvement in the 1970s (wheat-maize double cropping is one of the key parts); Comprehensive technology for severe saline-alkali and sandy soil improvement in 1980s; Efficient planting and animal husbandry technology in the 1990s; comprehensive technology for maize production and recycling industry in the 2000s^[12].

Thanks to these saline and alkali soil improvement technologies, the grain yield per unit area under the ??wheat-maize double cropping system?? in Yucheng city has reached 15 ton /ha in 2021. In the future, with the improvement of farmland infrastructure (ditch, bridge, road, canal, culvert, well, forest and electricity), as well as the construction of the water source project of Shinu lake and the clean-up and siltation project of Tuhai river, the soil productivity of Yucheng will be further improved, and the maize yield in the core area is expected to be 22.5 ton/ha.
