Applying the 7-leaf stage of the whole-leaf-leafed corn, it is the optimum period for applying the jointed fertilizer. At this time, the corn leaves are fully expanded, and the stalks are rapidly elongated, requiring a large amount of fertilizer, generally to the full-leaf leaves. At the 9-leaf stage, soil nutrients are difficult to meet the needs of corn growth. At this time, the corn should be grasped before and after the jointing of the 7~9 leaf stage, and the appropriate application of the seedlings and the late application, less application, the early application and re-application of the thin and thin seedlings, generally 15~20 kg of ammonium per acre, human and livestock Manure is 500~750 kg.
The booting stage of the full-water booting stage is the period of most water demand. Generally, the water requirement for plant growth at the booting stage of corn is about 27%~38% of the total water requirement during the whole growth period. The soil moisture in this period should be kept at 70% of the field water holding capacity. 75%, with water and fertilizer, to meet the needs of fertilizer growth and development of corn.
Re-application of panicle fertilizer and panicle fertilizer can not only improve the photosynthesis efficiency, but also promote the growth of the panicle leaves and the upper and lower leaves, and can extend the life of the leaves and promote the fullness of the seeds. The application time of panicle fertilizer is related to corn variety and soil fertility. Generally speaking, the early maturing varieties are in the visible leaves of 15~16 pieces or the unfolded leaves 8~10 pieces; the middle and late-maturing varieties are suitable for 15~17 pieces of visible leaves or 11~12 pieces of unfolded leaves, and the base fertilizer is sufficient and the growth is strong. For plots, it is advisable to apply panicle fertilizer slowly. It is advisable to start planting a small number of plants in the whole field; the growth potential of lean soil with insufficient base fertilizer is poor, and the ear fertilizer should be applied early. Spike fertilizer should use quick-acting nitrogen fertilizer. Generally, 25-35 kg of ammonium bicarbonate is applied per acre or if 7.5~10 kg of urea is used.

Aluminum Investment Casting
At Taiyuan Simis
Investment Casting Co., Ltd, we specialize in aluminum investment casting, utilizing advanced technologies and processes to deliver high-quality, precision components. Our capabilities extend across various industries, including aerospace, automotive, and industrial machinery, where the unique properties of aluminum are particularly advantageous.
Advanced Manufacturing Processes
Our aluminum investment casting process is distinguished by its precision and adaptability. We start with creating a highly detailed wax model that reflects the exact specifications of the desired part. This model serves as the basis for building a ceramic mold, which is constructed layer by layer until it achieves the necessary durability and thickness. The wax is then melted away, leaving a perfect cavity for the molten aluminum.
We pour high-quality aluminum alloys into the preheated ceramic molds. This stage is critical as it requires precise temperature control to ensure the aluminum flows evenly, filling the intricate geometries of the mold without defects. Once the aluminum solidifies, we carefully remove the ceramic shell, revealing the cast part which often requires minimal finishing due to the excellent surface finish that investment casting provides.
Customization and Design Flexibility
One of the standout aspects of our service is the level of customization and design flexibility we offer. Our in-house engineering team works closely with clients to develop components that meet specific requirements. This collaborative approach ensures that every design detail is optimized for both performance and manufacturability.
Material Expertise
We use a variety of aluminum alloys in our investment casting processes, each selected for its specific properties to suit different applications. These materials include, but are not limited to, A356, a popular choice for its good strength and excellent corrosion resistance; and A357, known for its high strength and resistance to hot cracking, making it ideal for critical aerospace components.
Quality Control and Assurance
Quality is at the core of everything we do at Taiyuan Simis Investment Casting Co., Ltd. We employ rigorous quality control measures throughout the casting process to ensure that every component meets the highest standards. Our facility is equipped with the latest in testing and inspection technology, including x-ray imaging, ultrasonic testing, and coordinate measuring machines that provide precise dimensional and structural analysis of each casting.
Applications and Industries Served
Our aluminum investment castings are utilized in a wide range of applications. In the aerospace industry, we produce lightweight, high-strength components that contribute to the overall efficiency and performance of aircraft. The automotive sector benefits from our ability to cast complex parts that reduce weight without sacrificing strength, enhancing fuel efficiency and performance. Additionally, we manufacture components for industrial machinery, where the durability and resistance properties of aluminum are crucial for long-lasting, reliable operation.
