The fat of squid contains a large amount of highly unsaturated fatty acids such as EPA and DHA, plus the high amount of taurine contained in the meat, which can effectively reduce the cholesterol accumulated in the blood vessel wall, which is effective in preventing vascular sclerosis and the formation of gallstones. Quite effective. At the same time, it can replenish brain power and prevent Alzheimer's disease. Therefore, squid is healthy food for middle-aged and elderly people who are prone to cardiovascular diseases.

Maize two-plant cultivation management
Maize two-plant cultivation technology refers to a method where two corn plants are left in each planting hole after the seedlings have been established. This technique is particularly beneficial for increasing yield and improving crop quality. The main advantages include better air circulation, improved light penetration, and higher planting density, which together can help achieve a yield of up to 1000 kg per mu (approximately 667 kg per hectare).
The key aspects of this cultivation method include:
**Variety Selection**: It's important to choose short-statured and high-yielding varieties such as Zhengdan 958 or Qinlong 11, which are well-suited for dense planting and can maximize productivity.
**Planting Methods**: The wide-narrow row system is commonly used, with wide rows measuring 80 cm and narrow rows at 40 cm. Two plants are placed in each hole, with a spacing of 40 cm between holes, resulting in approximately 5000 plants per acre. Early spring mulching is recommended to raise soil temperature and promote faster germination.
**Timely Watering**: Adequate irrigation during the seedling stage is crucial to ensure uniform emergence and healthy growth. In dry conditions, sufficient water should be provided, including male water (water applied during the tasseling stage) and ear-filling water (to support kernel development).
**Fertilization Management**: A balanced fertilization strategy is essential. Basal fertilizer, such as organic manure (about 1500 kg per mu) and compound fertilizer (25–30 kg per mu), should be applied before sowing. During the 5–6 leaf stage, a jointing fertilizer (around 20 kg of urea per mu) is recommended. At the large boot stage, additional urea (about 30 kg per mu) should be applied along with soil cultivation to enhance nutrient uptake.
**Pest Control**: Focus should be placed on managing pests like the armyworm and corn borer. Armyworms can be controlled using 40% phosphamidon at a dilution of 500–600 times or 2.5% chlorpyrifos at 1000 times. For corn borers, early detection is key—when young larvae appear, they can be manually removed. Before the stalks are cut, 1.5% phoxim granules can be placed directly into the whorl. Alternatively, 90% trichlorfon at 800–1000 times or 75% phoxim emulsion at 1000 times can be sprayed on the ear for effective control.
By following these practices, farmers can significantly improve both the quality and quantity of their maize harvests, making two-plant cultivation an efficient and sustainable approach.
