The winter flower, also known as Ai Donghua and 99 flowers, is the flower bud of the winter plant, similar to the dandelion. It is widely used as medicine because it has the effect of relieving cough and resolving phlegm and moistening the lungs. What is that winter flower? What are the planting techniques?

What is a winter flower?

1. The winter flower is the flower bud of Campanulaceae, Compositae, Tubular subfamily, Qianliguang and Diedongdong perennial herbaceous plants, the long roots are brown, grow horizontally in the ground, the long leaves are very small, long oval to triangular, the long flowers are heads, petals are generally one or two layers, bright yellow, similar in shape to dandelions, usually bloom in February to March, and bear fruit in April.

2. Flos Lonicerae is a kind of plant with high medicinal value, which contains rutin, triterpenoid saponins, hyperin, dandelion yellow and other elements, which has the effect of relieving cough and moistening the lungs. therefore, it can be used to treat cough, chronic bronchitis, chronic osteomyelitis and other diseases caused by cold and heat or exogenous diseases.

3. Winter flower is a kind of plant with strong growth power, which can grow in places with humid climate and cool weather, so it grows by the edge of the ditch. At present, it grows in Heilongjiang, Liaoning, Jilin, Beijing, Hebei, Tianjin, Shanxi, Inner Mongolia, Shaanxi, Gansu, Ningxia, Qinghai, Hunan, Yunnan and other places in China.

Second, what are the planting techniques of winter flowers?

1. Land selection and preparation: which land is suitable for planting?

Winter flower is suitable to grow in the environment of loose and fertile soil and good drainage, so when selecting land, we should choose sandy loam as far as possible. After selecting the land, it is necessary to dig the soil deeply and apply 1250 kg of mature compost per mu, and finally flatten it for later planting.

2. Sowing and raising seedlings: how to sow seeds?

(1) seed collection and treatment: when the winter seeds are ripe, pick the fruit, then put it in gauze and expose it to the sun for a day or two, and finally rub it repeatedly with your hands until the seed is rubbed out.

(2) sowing method: Flos Lonicerae can be sown by strip sowing or hole sowing, in which the strip sowing method is to sow the seeds evenly in the soil according to the row spacing 25cm, then spread the seeds evenly in the soil, then gently spread the thin soil, and finally cover it with plastic film or straw to let it emerge freely. Hole sowing is to sow seeds into the cave according to the distance between 20cm and 35cm.

3. Transplanting: how to plant?

(1) transplanting time: when the soil is thawed at the beginning of spring.

(2) transplanting method: dig out the seedlings with roots in the soil, then dig a cave with deep 8cm and wide 25cm according to the distance between the plant and the 25cm, then plant 2-3 seedlings in each cave, and finally cover the soil and step on it.

4. Field management technology: how to manage it?

(1) Seedling replenishment: after the seedlings are unearthed, the plastic film or straw should be removed, and then the seedlings in the garden should be checked. The dead seedlings and weak seedlings should be pulled out in time, and the dense seedlings should be transplanted to the place where there are no seedlings in time to ensure the evenness of the seedlings.

(2) ploughing and loosening the soil: after the seedlings have grown, the weeds in the field should be removed in time, and the soil should be loosened shallowly to speed up the growth of the root system.

(3) Fertilizer requirements: winter flowers do not have high requirements for fertilizer. In general, about 1000 kg of compost can be applied per mu when weeding is ploughed and weeded, and 15 kg of nitrogen fertilizer and 8 kg of phosphorus fertilizer can be applied per mu at the bud stage. and add 1 to 2 times, the rest of the time according to soil fertility and plant growth to determine the number of times and amount of fertilizer.

(4) Water requirements: winter flowers do not have high water requirements, and they should be watered more in spring drought, and drainage measures should be taken in Meiyu season.

The above is a detailed introduction of what the winter flower is and its planting technology. I hope it will be helpful to you.
