This is Weixian County in winter. The vast wheat fields are brimming with the vitality of green and also nurturing new hopes for high-standard farmland. Who could have imagined that this small city in southern Hebei would once fall into a predicament in agricultural development due to excessive groundwater extraction? Nowadays, with the advancement of the all-round water network strategic project, an ecological picture of "turning dry land into good farmland" is unfolding here.
People's livelihood project Break through the development bottleneck
Wei County is located at the southernmost tip of Hebei Province and suffers from a severe shortage of underground water resources. The entire county is an area of excessive groundwater exploitation, and the water network project throughout the region has become a strategic regional project. As a key livelihood project for rural revitalization, the Weixian County All-Region Water Network Project takes the construction of farmland pipe networks as its core. Through a systematic project of "water source restoration + intelligent control and management", it realizes a modern irrigation system featuring "water network connectivity, active pumpng stations, main and branch connection, and drought irrigation capacity".
The surface water irrigation project of the entire water network in Weixian County involves three areas: the southeast, northwest and northeast of Weixian County. It aims to build water systems, roads and greenery simultaneously. It is a comprehensive project integrating multiple functions such as irrigation and water supply, flood control and drainage, ecological tourism and smooth transportation. The combined total length of the water network, road network and forest network exceeds 670 kilometers.This water network project will restore and excavate 36 main and branch canals, expand and renovate 168 ponds, covering an area of 4,429 mu, with a total water storage capacity of 10.43 million cubic meters. New water gates, culverts and Bridges, inverted siphons, pumping stations and supporting field pipeline projects will be built. Modern water measurement facilities and intelligent control systems will also be constructed.It is the largest surface water irrigation project of the entire water network in North China.
The large-diameter buried pipeline of ERA- the PVC-U pipe for low-pressure irrigation - brings water sources to this farmland in urgent need of cultivation. Through scientific layout and laying of the pipeline network, it ensures the operation of the irrigation waterway system, allowing farmers to open the water outlet at any time and make timely use of water resources.
Under the strategic guidance of "storing grain in the land and in technology", Weixian County has activated agricultural ecology through water network construction and connected the road to harvest with technological pipes, thus painting a new picture of high-quality development of modern agriculture.
Technical breakthrough Consolidate the foundation for a bountiful harvest
Since last October, as truckloads of pipes from the transport vehicles have been unloaded in an orderly manner, the laying of over 230,000 meters of pipes has been fully launched on this land. The project team was stationed in Weixian County for nearly eight months. They were involved in the construction from the beginning, providing support for the design and construction, and guiding the on-site operations in an orderly manner.
To reduce the impact of construction on planting, the winter when wheat is dormant becomes the golden window period for construction, but this also brings difficulties in construction.
PVC-U material is relatively brittle at low temperatures and is more likely to cause damage to the pipes during construction, transportation and storage. In theory, it is not recommended to carry out construction in the extremely cold winter. To align with the project schedule, the ERA team resolutely accepted this arduous task. With scientific coordination and professional guidance, the team assisted the on-site construction to advance in an orderly and efficient manner. The tough performance of the ERA PVC-U pipes also brings great convenience to construction, effectively reducing the adverse effects of climatic conditions and injecting wisdom and efficiency into agriculture.
New national standards will be implemented for agricultural pipes starting from April 1, 2024. The new standard further raises the requirements for various indicators of pipes and imposes stricter quality standards on products, such as adding requirements for pipe opacity, increasing elongation at break, and adding flattening tests, etc.As the first project after participating in the compilation of the new standard [" GB/T 13664-2023 Rigid Polyvinyl chloride (PVC-U) Pipes for Low-Pressure Irrigation "standard], ERA adopted more standardized PVC-U pipes and fittings for irrigation. On the basis of ensuring quality, it strictly controlled costs, precisely configured pipe layouts, and simplified design and construction. With a 20-year warranty commitment, it far exceeds the lifespan of conventional agricultural pipes, fully meeting the functional and quality requirements of pipelines in irrigation scenarios, and providing strong support for the construction of high-standard farmland in Weixian County.
Environmentally friendly formula: PVC-U adopts a lead-free formula, which does not pollute water quality, is conducive to the healthy growth of crops, and also meets the high environmental protection requirements of modern agricultural production.
Quality performance: ERA PVC-U pipe has strong corrosion resistance, anti-aging properties, and excellent mechanical performance.It can be used for a long time in underground environments, saving land resources and having a service life of up to 20 years.
Strong water drainage: The inner wall of PVC-U is smooth, with low water flow resistance and fast water drainage speed, effectively preventing clogging problems and ensuring the stability of water drainage. As a rigid pipe, it has the performance of resisting external forces and withstanding pressure. When buried for drainage, it can effectively prevent the deformation and damage of the pipe caused by external forces such as soil settlement, ensuring the safety and efficiency of the irrigation system.
Efficient installation: ERA PVC-U pipes and fittings are fully equipped, lightweight in material, and have a simple connection method. They are connected by bonding, which makes the installation process fast and cost-effective, improving efficiency and saving labor.
"Technological wisdom" Empower high-quality agricultural development
General Secretary Xi Jinping pointed out that，“A strong agricultural country is the foundation of a modern socialist power.”Recently, the Central Committee of the Communist Party of China and The State Council issued the "Plan for Accelerating the Building of a Strong Agricultural Country (2024-2035)", putting forward requirements such as strengthening the construction and transformation of modern irrigation districts and improving the agricultural water conservancy infrastructure network. The "Comprehensive Rural Revitalization Plan (2024-2027)" mentions accelerating the construction and renovation process of irrigation districts, and has made clear requirements for promoting the prevention and control of excessive groundwater extraction,soilerosion, and heavy metal pollution in soil.
With the support of policies, a large number of agricultural infrastructure projects have sprung up, providing greater support for China's goal of increasing grain production. In the high-standard farmland demonstration area of Guangrunpo, Anyang, Henan Province, ERA is involved in 662.5 kilometers of UPVC pipes. In the Suken Demonstration Farm in Yancheng, Jiangsu Province, the HDPE solid-wall irrigation and aquaculture pipes from Gongyuan have been applied, providing complete support from the main pipe to the branch pipes and the water outlet.
In projects such as the high-standard farmland in Daqi, Inner Mongolia, the water and fertilizer integration project for sugarcane planting in Zhangzhou, the modern agricultural demonstration park in Taizhou, Jiangsu, the unmanned farm in Qingpu, Shanghai, and the high-standard farmland in Dongtai, Yancheng, Jiangsu, ERA has been empowering the high-quality development of agriculture with high-standard products and high-quality services, accelerating the transformation and upgrading of agricultural modernization, and enhancing agricultural production efficiency. Provide new ideas and directions for regional agricultural development.
Under the era's proposition of building a strong agricultural country, ERA has been continuously delving into the agricultural sector. With over four decades of development confidence, it has pushed agricultural production efficiency and economic value to new heights, making greater contributions to national food security and the sustainable development of agriculture.
