When to plant dandelion planting techniques and matters needing attention

Although the main form of existence of dandelion is still rural weeds, with the wide spread and application of the efficacy and function of dandelion, planting dandelion has also become a means for rural entrepreneurs to get rich. So how on earth can dandelion be planted in order to have better quality and high yield?

When will dandelions be planted?

Dandelions are sown after July. Dandelion is resistant to cold and heat, and the sowing date is not very strict. Spring and summer vegetables can be sown after harvest. The yield of dandelion is related to the sowing date. According to the experiment, the annual production of Lesser Heat, Greater Heat and the Beginning of Autumn is 0.71kg, 0.60g and 0.36kg per square meter respectively. Therefore, we should sow as early as possible, if sowing after July, we can appropriately increase the amount of sowing to increase the yield.

Planting techniques and matters needing attention of dandelion

1. Land selection and preparation

Dandelion has strong adaptability and can be used in general land. choose Xiangyang sandy soil with fertile and moist soil, pour water thoroughly before sowing, apply sufficient base fertilizer, apply organic fertilizer, phosphate fertilizer and potassium fertilizer, turn the land deeply, level it fine, and water it after making the bed.

2. Sowing seeds

Mature dandelion seeds have no dormancy period and can be sown in moist soil when the temperature is above 15 degrees. It can sprout after about 90 hours. Seeds germinate faster when the soil temperature is about 15 degrees, and slowly when the soil temperature is above 25-30 degrees, so seeds can be sowed from early spring to midsummer.

3. Fixed seedling

In post-planting management, new leaves are generally not watered before growing, such as spray pot watering when the soil is dry. After the new leaves grow, they can be watered according to the soil moisture, and the soil surface of the border should be dry and wet. At the same time, we began to loosen the soil and ridge, and found that the missing seedlings should be replenished in time, and should not be watered within 2-3 weeks after planting to prevent rotting roots.

4. Field management

Dandelion has strong disease resistance, drought resistance and insect resistance, and generally does not need to carry out pest control. The focus of field management is mainly fertilizer and water. Although dandelion is not strict with soil conditions, it still likes soil with rich, moist, loose and high content of organic matter. In the growing season, topdressing should be done 1-2 times.

5. Harvest

In summer and autumn, the whole grass is cut before flowering, dried and used as medicine. After growing for two years, at the end of autumn, dig out the roots and dry them in the sun and use them as medicine. Cooking can be harvested and processed at the right time. If the temperature is kept above 10 ℃ in the greenhouse, the dandelion plant can grow normally, and when the plant grows to a suitable size, it can be harvested and put on the market.
