Planting benefits and conditions of Platycodon grandiflorum planting method of Platycodon grandiflorum

Platycodon grandiflorum is a kind of plant which integrates ornamental and medicinal use. it is used in the root and has the effect of moistening the lungs, expectorant and purulent. At present, it is a very popular plant on the market, so many people want to plant it. So can planting Platycodon grandiflorum really bring good economic benefits?

Planting benefit of Platycodon grandiflorum

The advantage of planting Platycodon grandiflorum, like other crops, is that it does not take up agricultural time, sowing in idle time (November of the lunar calendar to March of the following year), harvesting in idle time, and most of the growing period is one year. Each mu needs to invest 10,000 jin of ring fertilizer or 100 jin of compound fertilizer, discount 100 yuan, seed 2 kg, 160 yuan, labor about 300 yuan, a total of 560 yuan. The average annual output is more than 1000 kg, with a high yield of 1500 kg. According to the current purchase price of 4 yuan / kg, the mu income is 2800 yuan, plus 300kg foreign products. The processed medicinal material (the drying rate is 3:1) is 100kg, and the current purchase price is 10 yuan / kg, totaling 1000 yuan, as well as seed income. 20 kg seeds are produced per mu in the same year, and 40 yuan / kg is 800 yuan. The total income per mu is 4600 yuan. After deducting the cost, the income per mu is more than 3800 yuan.

Planting conditions of Platycodon grandiflorum

Platycodon grandiflorum likes warm and humid climate. Cold-resistant, can withstand the low temperature of-40 ℃, but also can withstand the high temperature of 40 degrees. Resistant to drought and afraid of water stains. It is suitable to grow in an environment with plenty of sunshine and plenty of rainfall. It is better to use sandy loam or loam with deep soil layer and rich organic matter. The seeds germinated in 15 days under the condition of 10 ~ 15 ℃, and the germination rate of aged seeds was low every other year, so it was not suitable for seed. The suitable growth temperature is 18 ~ 33 ℃. Biennial plants are easy to lodge in the face of wind and rain.

Planting method of Platycodon grandiflorum

1. Soil preparation and fertilization: select sandy loam fields with high topography, good drainage, deep soil layer, loose and fertile soil, rich in organic matter, deep ploughing and careful cultivation, ploughing depth above 30cm. Combined with soil preparation, apply sufficient basic fertilizer: 5000 kg of soil miscellaneous fertilizer per mu, (or 100kg of cake fertilizer), 25kg of urea, 30kg of diamine and 20kg of potassium sulfate. The land will be leveled and raked into pieces, and the drainage ditches will be dredged around, waiting for sowing.

2. Sowing: Platycodon grandiflorum is propagated with seeds. There are spring sowing, summer sowing, autumn sowing and winter sowing, but winter sowing and spring sowing are good and neat. When sowing, mix Platycodon grandiflorum seeds with yellow sand at 1:10, then evenly sprinkle them evenly on the whole border surface, flatten them with a rake, and make the soil cover without seeds. The sowing rate per mu is 2ml / mu and 3kg / mu

Field management of Platycodon grandiflorum

1. Interseedling and supplementary seedling: thinning the seedling properly when the seedling height is 2 cm, setting the seedling when the seedling height is 3 mi 4 cm, and keeping a strong seedling with a distance of 10 cm to 13 cm. Replenishing seedlings and inter-seedlings should be carried out at the same time, and seedlings should be transplanted with soil:

2. Intermediate ploughing and weeding: weeding is carried out for the first time by asking seedlings. After rain or watering, the soil should be loosened and weeded. At ordinary times, weeds should be removed as soon as there are weeds, and there should be no weeds in the field. After the plant grows up and closes, it is no longer suitable for ploughing and weeding.

3. Fertilization: combined with asking seedlings, fixing seedlings and irrigation, applying dilute human feces and urine to promote seedling growth; when the seedlings are 67 cm high, apply 10 kg of urea and 20 kg of superphosphate per mu.

4. Topping: when the seedling height is 10 cm, the remaining plants are topped in order to increase the number of seeds and the plumpness of seeds, and improve the quality of seeds.

5. Soil cultivation: after topping, combined with fertilization, weeding and soil cultivation, so as to prevent the plant from being broken by the wind.

6. Bud removal: bud removal and flower picking is an effective measure to increase the yield of Platycodon grandiflorum. 1000 ml / L ethephon should be sprayed once in full bloom, which can basically achieve the purpose of flower removal, and the yield is 45% higher than that without spraying.

7. the pests of Platycodon grandiflorum are mainly underground pests, such as ground tiger, grub, golden needle worm and so on. If the tiger in the area can be controlled by killing 40ml / mu by the enemy, the grub can be removed manually when ploughing, and 2000 times diluted by phoxim in the later stage of emergence. The main disease of Platycodon grandiflorum is rot, that is, rot occurs at the junction of the root and the outside world, and then the whole plant dies. The method of prevention and treatment can be sprayed with Kangkuling and streptomycin. Each Kangkuling to streptomycin, add 20 kg of water, spray 0.5 mu of land.

The economic benefit of Platycodon grandiflorum is still good, but not everyone can make money by planting. If you want Platycodon grandiflorum to have good economic benefits, you need to master its high-yield technology. When planting Platycodon grandiflorum, we need to understand its growth habits, timely planting, and strengthen field management in the later stage. Only by doing these well can Platycodon grandiflorum grow well and have high yield.
