As the main area for the cultivation of platycodon grandiflorum, Guizhou has an annual planting area of ​​about 800,000 mu. However, due to the special topography and geomorphology of Guizhou, mechanized planting is difficult, and the cost of artificial planting is high, and the planting efficiency is low. Combining with the topography and geomorphology of Guizhou, this paper analyzes and screens the platycodon seeder suitable for hilly and mountainous features, and continuously tests, demonstrates and promotes it in Guizhou.
1 Choosing the right planting environment
The platycodon is a straight root plant with a mild, cool and humid environment. Due to the relatively complex terrain in Guizhou, it is necessary to choose a higher hillside or flat land with an altitude of over 1000m. And choose a deep and fertile soil layer to create a good drainage environment for planting platycodon.
After the selection of the ground, fertilization is required. The soil fertilizer, potassium sulfate, diammonium phosphate and three-element compound fertilizer can be applied according to a certain ratio to prevent the problem of excessive fertilization or insufficient fertilization. The terrain in Guizhou is complicated and cannot be used as an overall field. However, it is also necessary to pay attention to maintaining the width of the field and the width between the trenches being kept at around 25 cm.
2 Choose a good seed
Good seeds are the premise of planting platycodon grandiflorum, which directly affects the growth effect of platycodon grandiflorum. Seeds with a germination rate above 90% are selected, preferably full seeds from the platycodon grandiflorum for 2 years. Seeds need to be treated after seeding. The methods are divided into several types: 1 soak the seeds in warm water of about 50 °C, stir them continuously, soak for about 10 hours, and then directly sow; 2 wrap the seeds with a damp cloth and place them At about 30 °C, rinse with warm water every morning and evening, germination treatment, after 5 days, you can sow; 3 soak with 0.5% potassium permanganate, after 12h can be seeded.
3 platycodon mechanized planting method
The terrain of Guizhou is complex, including the topography of the plateau, mountains, hills and basins, so it is impossible to mechanize planting in large areas. According to the current situation of Guizhou stalks planting and the characteristics of hilly mountains, a self-propelled fine platycodon seeder can be realized which can realize adjustable walking speed, precise sowing and infinitely adjustable seeding amount. The self-propelled platycodon seeder mainly comprises an engine, a wheel-row wheel seeder, an opener, a walking wheel, a front and rear roller and the like. Considering that the platycodon seed particles are small, the seeding depth is very high (generally controlled 1 to 3 cm). In order to ensure the depth of sowing, the front pressure roller ensures the soil level before planting. When planting, the depth of the trench is effectively adjusted by adjusting the opener adjusting screw. After the soil is planted, the roller is pressed to smooth the soil to ensure a uniform seeding depth.
The sowing method of the platycodon is mainly broadcast live, and the autumn broadcast time is from mid-November to mid-November. When broadcasting live, it needs to be planted on the prepared field and planted in a ratio of 1.5kg per mu. Place the treated seeds on the self-propelled platycodon seeder, adjust the ditch width of the planter, about 20-25 cm, adjust the ditch depth to 2 cm, and then control the self-propelled bellflower machine. When using the self-propelled orange machine, you need to pay attention to control the speed of its travel, to ensure uniform planting, and at the same time, pay attention to the planted seeds at the end of the field to prevent over-grown or improper planting. The same spring time is selected from mid-March to mid-April, and the planting method is the same as that in autumn. Watering is required after planting to ensure the soil is moist.
The platycodon self-propelled planter greatly improved the planting efficiency of the platycodon grandiflorum, liberated the labor force, and improved the scientific and normative cultivation of the platycodon grandiflorum. The platycodon self-propelled seeder is suitable for the special terrain of Guizhou and can be widely promoted and used in the uneven terrain.
4 Platycodon planting completed follow-up work
After the completion of the platycodon grandiflorum, a series of management tasks are required, including watering, drainage, fertilization, and de-worming in the field. In the growth process of the platycodon grandiflorum, it is necessary to fertilize according to the growth cycle and planting environment to ensure the fertility of the soil, and at the same time, it is necessary to regularly water to ensure the germination and normal growth of the platycodon grandiflorum. In addition, de-worming is an urgent problem in the growth process of platycodon grandiflorum. During the growth of platycodon grandiflorum, anthracnose, blight, root rot, etc. will occur. Therefore, it is necessary to remove worms in time to reduce the impact of the natural environment on the growth of platycodon.
5 Conclusion
Platycodon grandiflorum is a traditional Chinese medicinal material and foodstuff. It has been widely grown in China, and most of the northern platycodon has been selected for mechanized planting and harvesting. However, the terrain in Guizhou Province is relatively special, the degree of mechanization is low, and many large machinery cannot be used. The article analyzes the self-propelled platycodon planter, which can be used in the complex Guizhou area. The self-propelled platycodon planter has a small overall footprint, clear structure and convenient transportation. Therefore, it can be widely promoted in Guizhou. During the mechanized planting process of the platycodon grandiflorum, attention is paid to the preparation of the platycodon grandiflorum, and the good topography and seeds are selected, so that it can form a seamless connection with the self-propelled platycodon seeder and make full use of it. In addition, after the planting of the platycodon grandiflorum requires a lot of field management work, watering, fertilizing, deworming and other work to ensure the good growth of platycodon.
The above is the whole content of the platycodon cultivation organized by Huinong. I have more understanding of the mechanized planting of the platycodon grandiflorum? If you want to know more about agricultural technology, please pay attention to the Hui Nong School!
