Introduction of four key points for high-yield cultivation of dandelion!

Dandelion is also called dandelion grass, etc., because it is a plant for both medicine and food, and it has the effect of clearing away heat and detoxification, detumescence and knot, it is liked by many people, so it also attracts many people to plant it artificially, but the yield of dandelion planted by some growers is not high, so the editor will introduce to you the four main points of high-yield cultivation of dandelion:

1. Point 1: harvest seeds

Dandelions generally blossom and bear seeds at the age of 2 years. Wild dandelions blossom from May to June with single plant and community growth. The older the dandelion is, the more it will blossom and the more than 20 flowers will blossom at most. After flowering, the seed maturity period is generally shorter than 13-15 days. Whether the seed matures or not mainly depends on the disk shell changing from green to yellow, and each disk seed also changes from white to brown, that is, the seed can be harvested during the seed maturity period. Soon after the seeds are ripe, the catkins fly away with the wind, and they can be harvested at the end of the disk when they crack, which is the key to the success or failure of seed harvesting. After the disk is picked, it is ripe indoors for 1 day, and then dry in the shade for 1-2 days. When the seeds are semi-dry, rub off the flannel at the end of the seed by hand and then dry the seeds. The 1000-grain weight of the big-leaf type is 2 grams, and the leaflet type is 1-1.2 grams.

2. Point 2: preparing the ground and making the bed

Dandelion has strong adaptability to both drought and alkali resistance, and likes loose, fertile and well-drained sandy loam. When applying organic fertilizer per hectare, it is best to apply 30000-45000 kg of horse manure per hectare, mixed calcium superphosphate 225,300kg evenly spread the ground, and then turn 20cm deeply. After the ground is leveled and raked fine, make a sowing bed that is 100cm wide * 15cm high * 10m long or a ridge 30cm high * 30cm wide * 20cm shoulder wide.

Third, the third point: sowing and burying the roots

Horizontally open a small trench 1 cm deep by 5 cm wide, sow the seeds evenly into the ditch and cover them with fine soil and suppress them with wood curl. The row spacing is 15 cm, and the furrow is 1 cm deep by 5 cm wide. After sowing, cover the fine soil and suppress it with wood clover. In order to increase income by digging roots in the field and planting them in the greenhouse, twice the result with half the effort can be achieved when dandelions are first hit by frost in mid-late October. To dig the dandelion root system in the field, the whole root is the best, and it is appropriate to plant the root according to the row spacing of 15 cm * plant spacing of 5 cm, and bury it to the surface of the original root, so that the root top seems to be exposed on the ground and compacted by hand. If the greenhouse temperature is controlled at about 20 ℃, the dandelion can grow normally. If dandelion is listed in the peak season of market demand, it is necessary to control the greenhouse temperature to limit the plant growth.

In addition, in order to make the seedlings emerge early after sowing, we can use warm water to promote germination, that is, stir the seeds in 50-55 ℃ warm water to cool and then soak them for 8 hours, put the seeds in a wet cloth in a place of about 25 ℃, covered with wet cloth, irrigate with 50 ℃ warm water once every morning and evening, and sow seeds after 3-4 days, 11.25kg per hectare.

4. Main points 4: field management

Half a month after the emergence of dandelion seedlings, loosen the soil and weed once, planing the seedlings with a small hoe, ploughing the ridges with picks, and ploughing the soil every 10 days. After the ridges are closed, the leaves of the plants on the ground are large, and the management should fully consider that there is a certain space for plant growth. The seedlings can be determined 10 days after emergence, and the plant spacing is 5cm. During the growth of dandelion, the soil should be often watered to keep the soil moist. Dandelion needs a lot of water after emergence, so keeping the soil moist is the key to the growth of dandelion.

Summary: the above is the introduction of the four main points of high-yield cultivation of dandelion. When planting, you can refer to the above four points to plant. I hope it will be helpful to friends in need!

How to achieve high yield in dandelion cultivation? High-yielding planting techniques of dandelion

[FAQ] how to achieve high yield in dandelion cultivation?

Dandelion is a perennial herb of Compositae, which is rich in many kinds of healthy nutrients such as dandelion alcohol, dandelion, choline, organic acid, inulin and so on. it has high medicinal value and is very popular in the market in recent years. In order to improve the economic benefit of dandelion planting, it is particularly important to realize the high-yield planting of dandelion.

I. seed harvesting

Dandelions usually blossom and bear seeds at the age of two. It blossoms from May to June in the wild, and there are individual plants and community growth. Dandelions bloom more and more as they get older, with a maximum of more than 20 flowers. The seed maturation period is short after flowering, and the seed can mature in 15 days after flowering. Whether the seeds are mature or not mainly depends on the shell of the disk from green to yellow, and the seeds of each disk from white to brown, that is, when the seeds are mature, they can be harvested. After the seeds are ripe, the catkins will soon fly away with the wind, and they can be harvested at the end of the disk when they crack, which is the key to the success or failure of seed harvest.

After the flower plate is picked, it is ripe indoors for 1 day. When the flower plate is all dispersed and then dried in the shade for 1 or 2 days, when the seed is semi-dry, rub off the flannel at the end of the seed with your hands, and then plant it to dry. The 1000-grain weight of large leaf type is 2 g, and that of leaflet type is 1 Mel 1.2 g.

Second, make a bed by preparing the ground.

1. Site selection: dandelion has strong adaptability, both drought and alkali resistance, like loose, fertile and well-drained sandy loam.

two。 Fertilization: apply organic fertilizer per hectare, preferably horse dung, 30000-45000 kg, mixed calcium superphosphate 225,300kg, evenly spread the ground, and then turn 20 cm deep.

3. Make bed and ridge: after the ground is leveled and raked fine, make a seeding bed with a width of 100 cm, a height of 15 cm and a length of 10 m, or a ridge with a height of 30 cm, a base width of 30 cm and a shoulder width of 20 cm.

Third, sowing and burying roots

1. Sow seeds on the bed: horizontally open a small trench with a depth of 1 cm and a width of 5 cm, sow the seeds evenly into the ditch, cover them with fine soil, and suppress them with wooden stalks, with a row spacing of 15 cm.

two。 Ridge sowing: a furrow with a depth of 1 cm and a width of 5 cm. After sowing, cover the fine soil and suppress it with wood.

3. Buried planting: in order to get on the market early and increase income, digging roots in the field and planting in the greenhouse can get twice the result with half the effort. When dandelions are hit by frost for the first time in late autumn (mid-late October) and the leaves change from green to red, it is necessary to dig the roots of dandelions in the field, the whole root is the best. Make a bed in the greenhouse, as described above. According to the row spacing of 15 cm, plant spacing of 5 cm, buried in the original root surface position is appropriate, so that the root top seems to be exposed on the ground, can be compacted by hand. When the greenhouse temperature is controlled at about 20 ℃, dandelion can grow normally. If dandelion is put on the market in the peak season of market demand, the greenhouse temperature should be controlled to restrict the plant growth, and satisfactory results can be obtained.

4. Promoting budding and promoting seedlings: in order to promote seedling emergence early after sowing, you can use warm water to scald seeds, that is, put the seeds in 50-55 ℃ warm water, stir to cool, soak for 8 hours, fish out, and wrap the seeds in a wet cloth and put them in a place of about 25 ℃. It is covered with a wet cloth and watered with 50 ℃ warm water every morning and evening. The seeds can be sown after 4 days of germination. The sowing rate is 11.25 kg per hectare.

IV. Field management

1. Loosen the soil and weed: half a month after the emergence of dandelion, loosen the soil and weed once. The bed sowing is ploughed among the seedlings with a small hoe, and the ridge sowing is ploughed with a pick. After that, the soil was ploughed once every 10 days. Keep weeding manually after closing ridges.

two。 Fixed seedlings: the leaves of the aboveground plants of Pu Gongying are large, and the management should fully consider that there is a certain space for plant growth, and do not covet seedlings and affect their growth. Generally, the seedlings can be determined 10 days after emergence, and the row spacing is 5m / 10cm.

3. Watering and fertilization: dandelions should be watered frequently during their growth to keep the soil moist. Dandelion needs a lot of water after emergence, so keeping the soil moist is the key to the growth of dandelion.

V. Harvest

The sown dandelion could not be harvested that year. After entering winter, spread organic fertilizer on the bed (ridge) 2000 kg per 667m2, preferably rotten horse dung. In this way, it can not only play the role of fertilization, but also protect the root system safely through the winter. Do not advocate the application of chemical fertilizer, although the application of chemical fertilizer young plants and leaves black protruding long, but lost the connotation of green plants, but also lost the game style of dandelion. Generally speaking, each hectare can produce 9000m2, 10500kg.

[editor's conclusion] in order to meet the growing market demand and improve economic benefits, it is very important to realize the high-yield planting of dandelion. The high-yield planting techniques of dandelion are introduced above. I hope it can be helpful to you!
