1. Variety selection. Try to choose the small chives that have been planted in various places for a long time.
2. Nursery. As the life span of chives seeds is only about 2 years, it is recommended that vegetable growers use fresh seeds when raising seedlings. Small chives are generally sown in March to May, but can also be sown from September to October. The suitable temperature for germination is 13-20°C. Sow the seeds on the soil, cover the soil for about 1-2 cm, water it thoroughly, and unearth the soil in about 10-15 days. The seedlings grow slowly and can be transplanted and planted 35-40 days after sowing.
3. Colonization. Before planting, the seedlings should be screened to remove diseased, damaged, and weak plants. Transplant according to the row spacing of 20 cm and the plant spacing of 10 cm, each planting 4-6 plants. Spring onions and autumn onions can be planted sparsely. The planting should be shallow, about 3-5 cm, and the planting water should be poured in time after planting.
4. Field management. The root system of chives is relatively shallow, and the absorption capacity is relatively weak. Therefore, they are not tolerant of heavy fertilizers and droughts and floods. They must be watered frequently with small water. After the rain, the accumulated water must be drained. For topdressing with water, generally 5 kg of urea or 15 kg of ammonium bicarbonate is applied. Generally, it is applied once every 15 days, and no topdressing is applied 15 days before harvest.
5. Disease and pest control. Insect pest control mainly focuses on onion maggots, leaf miners, and thrips, while diseases mainly control blight, downy mildew and gray mold. Adopt agricultural and biological control measures, and scientifically use chemical pesticides.

A disposable specimen recovery bag is a single-use bag designed to collect and transport biological or medical specimens from one location to another. These bags are typically made of durable, leak-proof materials and feature a secure closure mechanism to prevent spills or contamination. Disposable specimen recovery bags are commonly used in hospitals, clinics, and laboratories to transport samples of blood, urine, tissue, or other bodily fluids for diagnostic testing or research purposes. Once the bag is used, it is disposed of in accordance with biohazard waste regulations to prevent the spread of infectious diseases.
1. Hygienic: Disposable specimen return bags are a very hygienic option because they are used once and then discarded. This helps prevent the spread of infection and cross-contamination.
2. Convenience: These bags are very convenient to use because they can be easily disposed of after use. This eliminates the need for cleaning and disinfection, which can be time-consuming and expensive.
3. Safe: Disposable specimen return bags are a safe choice as they are made of tear and puncture resistant material. This helps prevent accidental release of hazardous substances.
