Second, what are the planting techniques of dandelion?

1. Land selection and preparation:

Dandelion is very adaptable and does not have high requirements for soil. Generally, as long as it is fertile and moist, dandelion can grow, so it is best to choose the sunny sandy soil as far as possible. After selecting the land, appropriate watering and fertilization should be carried out to ensure sufficient water and fertilizer in the soil. When applying fertilizer, organic fertilizer, phosphorus fertilizer and potassium fertilizer should be applied as far as possible, and the soil should be turned deeply, and then leveled for subsequent planting.

2. Sowing:

(1) seed treatment: put the seeds in a cool and ventilated place to dry for 2 days, then soak in water for about 4 hours before sowing.

(2) sowing time: February to May and August to October of each year

(3) sowing method: spread the treated seeds evenly in the soil, then cover them with a thin layer of soil, and spray a small amount of water to make them grow. In general, it needs to be moved to about 15 degrees to grow, because when the temperature is 15 degrees, the seeds can germinate after about 4 days, if higher than 25 degrees, the growth will be slow.

3. Fixed seedlings:

10 days after the emergence of the seed, it is necessary to keep the 3~5cm between the seedlings, generally the plant spacing is the best. When it grows to about 30 days, the general plant spacing is the best to keep the 8~10cm.

4. Field management:

(1) Field management before sowing

Before emergence, just make sure the soil is moist. If the soil is very dry, sprinkle some thatch or wheat straw around the seedling according to the situation to ensure that the soil is moist. When the seedlings grow, remove the thatch and water it appropriately according to the soil moisture to promote the growth of leaves. In winter, water should be watered once, and then covered with thatch or wheat straw to protect the plant safely through the winter.

(2) weeding by ploughing

When the dandelion seeds emerge for about 10 days, the weeds can be ploughed and weeded every 10 days until the ridges are closed, so as to prevent weeds from regenerating and absorbing nutrients, resulting in insufficient nutrients and death of seedlings.

(3) Fertilizer and water management

Dandelions do not have high requirements for fertilizer and water, as long as the soil is moist and the fertilizer is suitable. Under normal circumstances, topdressing can be done twice during the growing period, and 2500 kg of organic fertilizer and 20 kg of calcium fertilizer per mu can be applied in winter to protect the root system safely through the winter.

When will the dandelion be harvested?

Dandelion is generally harvested from August to September, but because of its many uses, it can be used not only as vegetables but also as medicinal materials, so the harvest time is also different. The specific harvest time is as follows:

1. The harvest time of medicinal materials is the best in late autumn. Because at this time the dandelion has been fully mature, and the nutrition is the most adequate, the quality and efficacy of the roots dug out are better.

2. The time for vegetable harvest is the best when it is just sprouting in spring. Because at this time the dandelion leaves are young, the water is sufficient, the nutrition is also rich, and it is not very bitter to eat.

Generally speaking, dandelion is easy to grow, but in order to harvest successfully from August to September, it is necessary to do a good job in planting points such as water, fertilizer and sowing methods, so that it can be easy and high-yielding.
