The nutritional value of mussels is also high because the protein contained in them contains 8 essential amino acids such as valine and leucine, which are needed by the human body, and its content is much higher than that of eggs and essential amino acids such as chicken, duck, fish, shrimp, and meat.

Transplanting Film Cultivation Techniques of Spring Corn
Transplanting and mulching techniques for spring corn represent an innovative agricultural approach aimed at improving early seedling emergence, enhancing plant resilience, and increasing overall yield. This method involves raising seedlings in a controlled environment under plastic film, which protects them from early-season climate challenges such as frost and waterlogging. By combining the benefits of both transplanting and mulching, this system ensures better seedling survival rates, faster growth, and more uniform development. In Xiangshui County, this technique was applied to 30,000 mu of spring corn, resulting in an average yield of 642 kg per mu—an increase of 9.8% compared to traditional single-mulch methods. The practice not only improves ecological conditions but also helps corn grow on schedule, leading to higher productivity.
To implement this technique successfully, farmers must choose appropriate hybrid varieties based on local temperature conditions. When the accumulated temperature reaches between 2650°C and 2800°C, late-maturing hybrids like Dandan 13 and Dandan 12 are ideal for achieving high yields. For double-season or single-film cultivation, mid- to late-maturing varieties such as Dandan 22, Xiyu 3, and Suyu 9 are recommended. These hybrids have compact plant structures, strong stalks, and large ears, making them well-suited for transplanting under plastic film. They typically mature in mid-July, with minimal impact on post-harvest crops.
A key step in this process is the use of double-layer mulching. By placing an additional layer of plastic over the seedbed, the temperature increases by 2–3°C, accelerating soil warming and promoting even moisture absorption. This leads to stronger and more uniform seedling emergence. Timely transplanting, usually around April 5 when temperatures stabilize at 12°C, ensures that seedlings are moved before they become too large, maintaining high survival rates.
Fertilization plays a crucial role in this system. A nutrient-rich seedbed is prepared using compost, phosphate, ammonium bicarbonate, and potassium, mixed with Huimanfeng to enhance seedling resistance. The seedbed size is typically 1.5 m wide and 4.5 m long, with a ratio of 1:20 for seedbed to field area. Before planting, base fertilizers are applied, including 2,000–4,400 kg of manure, 20–25 kg of nitrogen, 10–15 kg of phosphorus pentoxide, 15 kg of potassium oxide, and 1–1.5 kg of zinc sulfate per mu. Herbicides such as atrazine and Dole EC are used to control weeds effectively.
Plant density is another important factor. High-yield fields generally require about 4,500 plants per mu, while super-high-yield fields may need up to 5,000–5,500 plants. Large and small row spacing (80 cm and 40 cm) is recommended to optimize light exposure and root development. Seedlings are transplanted into pre-dug holes, with fertilizer and water added to ensure good root-soil contact.
Timely topdressing is essential for optimal growth. At the 6-leaf stage, 15% of total nitrogen is applied as joint fertilizer. At the 10–11 leaf stage, 35% of nitrogen is used as panicle fertilizer to support ear development. Watering is critical during these stages to meet the crop's increased demand.
Pest and disease management is also vital. Carbofuran granules and methamidophos solutions are used to control underground pests, while trichlorfon is applied to manage corn borers. During the big bell stage, carbofuran is sprinkled into the heart leaves. Jinggangmycin is used to prevent sheath blight and leaf spot during tasseling.
Finally, proper drainage systems are necessary to avoid waterlogging. Trenches should be dug regularly to ensure efficient irrigation and drainage, especially after heavy rainfall. During dry periods, timely watering is essential to maintain healthy plant growth. Overall, this integrated approach offers a sustainable and effective way to boost spring corn production.
