The planting technology and mu income of Platycodon grandiflorum are generally about 20,000 to 30,000 yuan.

Sowing: it can be sowed in spring, autumn and winter, and the film should be uncovered in time after emergence. Planting: thinning seedlings in time. Weeding: weed regularly to prevent weeds from grabbing nutrients. Fertilization: timely topdressing, mainly rotten farm manure. Pest control: regular inspection, timely prevention and treatment of diseases and insect pests. Mu income: the mu income of the conventional planting method is about 20-30,000 yuan.

Yield and income per mu of Platycodon grandiflorum

Platycodon grandiflorum is one of 40 varieties of traditional Chinese medicine, which has high ornamental value and is a kind of plant with a wide range of uses. In the case of excellent varieties, good management, and no diseases and insect pests, the yield per mu is generally about 1200 kg, with a maximum of no more than 1500 kg, and its price is high and low according to the market situation, about 18-24 yuan per catty. Therefore, the income per mu is about 20-30,000 yuan.

Planting environment

The root ability of Platycodon grandiflorum is poor, so it is necessary to choose the soil with loose soil and strong permeability when planting. Pollution-free water sources are also needed around the planting land, and the conditions of drainage and irrigation are good, which is the best in the half-shady and half-sunny hillside.

After the planting is selected, the root of Platycodon grandiflorum is thicker and longer, so it is necessary to make ridges during soil preparation, first ploughing and deep turning, and then trenching, putting the soil pile in the ditch on both sides to make a ridge with a width of 2m, so as to provide a high quality growth environment for Platycodon grandiflorum.

Sowing seeds

Platycodon grandiflorum has strong adaptability and can be sown in spring, autumn and winter, because the temperature in summer is too high for germination.

The best sowing time is in September every year and around the Beginning of Spring, which is helpful for seeds to take root and germinate, improve their growth ability, and thus improve their quality and yield.

The best sowing method is strip sowing. Covering soil and plastic film in time after sowing can improve soil fertilizer and water retention, prevent the loss of water and fertilizer, and affect the germination rate of seeds. The film should be uncovered in time after emergence to ensure the normal growth of the seedlings.

Later stage management

After the seedlings grow to about 2 cm, the seedlings should be thinned in time according to their growth and density.

When the seedlings grow up, the seedlings can be fixed, and the spacing between fixed seedlings must be controlled to prevent the growth from being too dense. It is also necessary to pull out the dead seedlings and weak seedlings, and then replenish the seedlings to ensure their yield.

Weeding is also needed regularly in the later stage to prevent weeds from grabbing nutrients and affecting the growth of Platycodon grandiflorum. Topdressing in time is mainly based on rotten farm manure, which is helpful to improve quality and yield.

Control of diseases and insect pests

Platycodon grandiflorum will affect its income if diseases and insect pests occur, and in serious cases, it will lead to no harvest of Platycodon granule. For example, the most common diseases and insect pests are spot blight, aphids and so on.

Diseases and insect pests do great harm to Platycodon grandiflorum, so we must strengthen field management and disinfect them regularly. Reasonable topdressing is helpful to improve the disease resistance and immunity of Platycodon grandiflorum, thus reducing the incidence of Platycodon grandiflorum.

Regular inspection, timely detection of diseases and insect pests, timely prevention and treatment, so as not to bring unnecessary losses.
