Yining County Modern Agricultural Science and Technology Demonstration Park Scenic Area

　　The Yining County Modern Agricultural Science and Technology Demonstration Park is located in the eastern part of Sadikyuzi Township, covering an area of 5,323 mu, including a core area and an industrial zone. The core area is further divided into a modern facility agriculture zone and a field test zone. On April 29, a reporter visited this modernized park out of admiration. In the facility agriculture demonstration area of the core zone, rows of push-up double-arch double-film greenhouses stood in alignment, while seedlings in the distant fields were sprouting green. Entering the right-side greenhouse, which was humid and bright, one could see neatly arranged potted cherry tomatoes, with lush green vines hanging down with unripe fruits. The left-side greenhouse featured a steel-frame-built yin-yang style double-layer film arched greenhouse, standing five meters high, which not only provided ample sunlight but also offered insulation and energy efficiency. Inside the greenhouse were over ten varieties of southern flowers and celery grown through soilless cultivation. The celery, rooted in plastic pipe nutrient solutions, grew vigorously and healthily—about 30 plants were planted on a single 15-centimeter-wide plastic pipe, arranged in five diagonal layers along the greenhouse wall, forming a three-dimensional cultivation model. Zhao Zhenhua, the person in charge of the park, told reporters: “These are vegetables cultivated using specially prepared plant nutrient solutions. It’s still experimental, but they’re growing very well. If promoted successfully, it can save greenhouse space and improve utilization rates.”

　　Stepping into the push-up double-arch double-film greenhouse, one could see green melon vines laden with fruiting cucumbers ready for harvest. At the entrance of the greenhouse was a filtration and sterilization pool, with over ten ultraviolet insecticidal lamps hanging from the ceiling. Two staff members were picking ripe fruiting cucumbers. What impressed the reporter most was how different the air inside these greenhouses was compared to the murky and stuffy atmosphere often found in ordinary ones. These greenhouses use physical sterilization methods—such as UV-based pest control and sulfur vaporizers—to achieve sterilization and insect prevention without the need for any pesticides, and no unpleasant odors could be detected. According to the staff, these push-up double-arch double-film greenhouses have walls up to 8 meters thick at the base on the shaded side and 6 meters in the middle. The plastic film on the sunlit side is double-layered, giving them excellent heat retention properties. This allows for winter vegetable production without artificial heating, demonstrating remarkable energy-saving insulation performance. For developing pollution-free vegetables in the Ili River Valley, such greenhouses hold great potential for promotion.

　　In the northern part of the core area lies the forestry and fruit science and technology demonstration park, which features a hemispherical greenhouse shaped like a bird’s nest. This uniquely designed all-steel-frame greenhouse was built using a triangular cross-bracing method inspired by bird nests and reinforced with a honeycomb-like hexagonal structure. Dubbed the “Forestry and Fruit Science and Technology Demonstration Nest,” it has a diameter of 50.5 meters, a height of 16.8 meters, and covers an area of 2,000 square meters. Its insulation system uses double-layer film for light absorption and heat collection. Thanks to its triangular frame and hemispherical shape, it offers both wind and pressure resistance while maximizing spatial efficiency—a new technology now commonly used in large-scale greenhouses. Upon entering the park, the first thing one sees is a tower-like steel frame standing in the center of the nest, stacked from bottom to top with various fruit tree seedlings. Beneath the rotating ladder at the center of the steel frame is a clear pool, surrounded by trapezoidal racks holding hundreds of potted bag-grown tree species, while strawberries grow underground. Many of the potted tree species are newly introduced, premium, or special varieties from other provinces or abroad—such as early-ripening black peaches, Chinese sugar peaches, Flavor Queen plums, and American snake plums. It is understood that this demonstration nest can cultivate and grow 2,300 pots of various tree species annually, plus flowers, totaling 4,000 pots. If cultivating strawberries in three-dimensional layers, up to 4,000 plants can be grown, yielding a harvest of 2 tons; if focusing on potted fruit tree bonsai, at least 1,000 plants can be cultivated, generating an income of over 200,000 yuan.
