Chrysanthemum greens seeds are inexpensive, and the growing method is simple, so they are well worth a trial planting
Chrysanthemum greens are also called tonghao, penghao, haocai, juhuacai, tanghao, haozigan, haozi, and penghuacai. Chrysanthemum greens have a short growing period and few pests and diseases, can be cultivated in a wide range of seasons, and are extremely simple to manage; when sufficient base fertilizer is applied, measures such as intertillage weeding and spraying are not needed.Chrysanthemum greens seed price about how much per jin? What is the growing method?
I. Chrysanthemum greens seed price
The price of chrysanthemum greens seeds is about 15 to 20 yuan per jin, but prices vary widely depending on seed quality, variety, market, and purchase quantity. Chrysanthemum greens cultivars are divided by leaf into two types, large-leaf chrysanthemum greens and small-leaf chrysanthemum greens. Large-leaf chrysanthemum greens are tender in texture, low in fiber, good in quality, and relatively heat tolerant, but poor in cold tolerance, slow growing, and slightly late to mature, making them suitable for cultivation in southern regions. Small-leaf chrysanthemum greens have thinner leaf flesh, a strong aroma, thinner stems and branches, fast growth, and relatively strong cold resistance, but are not very heat tolerant and mature earlier, making them suitable for cultivation in northern regions.
II. Chrysanthemum greens seed growing method
(1) How are chrysanthemum greens seeds sprouted?
Before sowing chrysanthemum greens, it is best to soak the seeds in warm water at 35°C to 40°C for 5 to 6 hours, then sprout them at 2°C to 25°C. Once the seeds show white, they can be broadcast or sown in drills.
(2) How are chrysanthemum greens seeds planted?
1. Land preparation, bed making, and fertilization
Because chrysanthemum greens have a short growing period, fertile and loose sandy loam should be chosen. For every 667 sq m, use 2500 to 4000 kg of high-quality farmyard manure, 50 to 100 kg of superphosphate, and 50 kg of ammonium bicarbonate. Deeply plow the soil so that the fertilizer and soil are fully mixed. After raking level, make beds 1 to 1.5 m wide.
2. Sowing
Large-leaf chrysanthemum greens are mostly direct sown. Both drilling and broadcasting are acceptable. For broadcasting, sow 3 to 4 kg per 667 sq m; to increase yield and improve quality, the seeding rate can be increased to 5 kg. For drilling, open furrows in the bed at a row spacing of 15 to 20 cm, with a furrow depth of 1 cm, and water thoroughly. The seeding rate is about 2 kg per 667 sq m. After sowing, cover with 1 cm of soil. After sowing in early spring, plastic film should be added to protect against cold; when sowing in early autumn, because the temperature is relatively high and emergence is difficult, the seeding rate should be increased, and after sowing, shade should be provided to protect against high temperature and sunlight, with watering every day to keep the soil moist. Generally, full emergence occurs 6 to 7 days after sowing.
3. Field management
Thinning and weeding. When the seedlings grow 1 to 2 true leaves, thin them promptly. For broadcast sowing, the spacing of retained seedlings is 4 cm square; for drilling, maintain a plant spacing of 3 to 4 cm. Remove field weeds along with thinning. When raising seedlings for transplanting, once the seedlings reach about 30 days of age they can be set out, with a density of 16 cm × 10 cm being suitable.
Fertilizer and water management. For direct sowing in the field, after thinning, when the second leaf of the seedlings unfolds, the first watering can be given. For seedlings raised for transplanting, within 2 to 3 days after setting out, a small amount of water should be sprayed 1 to 2 times daily, and afterward a small watering should be given once each morning or evening until the seedlings recover. Chrysanthemum greens must not lack water during the growing period, and the soil should be kept in a moist state, but the field must not accumulate water. When sowing in early spring, after the seedlings emerge, moisture should be properly controlled to prevent damping-off disease. When the plants grow to 10 to 12 cm, begin the first topdressing, using 10 to 20 kg of urea per 667 sq m, and irrigate immediately after topdressing.
4. Harvesting
Harvesting of large-leaf chrysanthemum greens is divided into one-time harvesting and staged harvesting. One-time harvesting is done 40 to 50 days after sowing, when the seedlings are about 20 cm tall, by cutting close to the ground. Staged harvesting has two methods: one is thinning harvest, and the other is cutting while retaining 1 to 2 side branches. After each harvest, water and topdress once, and after 20 to 30 days another cut harvest can be made. The yield is 1000 to 1500 kg per 667 sq m.
5. Storage of large-leaf chrysanthemum greens
The optimum storage temperature is 0°C, and they can be stored for 10 to 14 days. At room temperature, after 1 day of storage, the leaves already appear wilted. The relative humidity should preferably be 98% to 100%, but condensed water must not gather on the leaves, otherwise they rot easily, and pre-cooling immediately after harvest is very important.
