More summer cultivation of chives
Chives are a popular vegetable known for their strong flavor and nutritional value. However, during the summer months, chive growth tends to decline, resulting in lower yields and reduced quality. To address this issue, the Vegetable Research Institute of Xinghua City has developed an advanced summer cultivation technique that significantly improves both yield and quality, achieving over 2000 kilograms per mu.
To begin with, choose a site with good drainage and irrigation facilities. Avoid planting chives in the same area consecutively. It is recommended to rotate with legumes or cruciferous crops. After harvesting, plow and dry the soil for about a week. Then apply 2000–2500 kg of organic manure per acre, along with 25 kg of specialized vegetable organic fertilizer. The beds should be 1.5 to 2 meters wide and 20 to 30 cm deep, with a planting depth of 15–20 cm.
Select healthy seedlings with thick stems and a strong root system (at least three fibrous roots). Transplant them from May to July, spacing plants 13–15 cm apart, with 12–13 cm between rows. Place 2–3 plants per hole, and cover them with 2.5–3 cm of soil. Water thoroughly after transplanting to ensure good establishment.
Before transplanting, it’s beneficial to place a thin layer of rice straw on the soil to help retain moisture and reduce heat stress. If possible, use shade nets or plant taller crops like corn around the chive field to provide natural shade. Maintain a density of about 200 plants per acre, or intercrop with fragrant onions in narrow rows among high-stalk crops like ginger.
After the seedlings are established, apply diluted human or animal manure, or 5 kg of urea per acre to promote growth. Fertilize lightly and frequently—every 12–15 days, applying 5–8 kg of urea and 4–5 kg of potassium chloride per acre, combined with watering. Fifteen to twenty days before harvest, apply 15–20 kg of urea per acre, and spray with bio-preparations such as Zhuang Sanqiu or amino acid fertilizers for added nutrition.
Common diseases include downy mildew, purple spot, rust, and soft rot. These can be managed using fungicides like chlorothalonil, metalaxyl-zinc, triadimefon, and streptomycin. Insect pests such as cutworms, cotton bollworms, thrips, and leaf miners can be controlled through methods like manual removal, sticky traps, or by irrigating the roots with water. For mole cricket control, apply 1.5–2 kg of 90% trichlorfon per acre mixed with fine soil before transplanting. Before planting, water the soil with 33% Shida at 125 ml per mu. During the growing season, if weeds appear, spray herbicides like weed grass or fine oil when the weeds have 2–4 leaves.
By following these techniques, farmers can successfully grow high-quality chives even during the hot summer months, ensuring better productivity and profitability.
