The Latest Cultivation Techniques and Methods Tutorial for Inula japonica

Inula japonica is a perennial herbaceous plant in the Asteraceae family, mainly distributed in the central part of Northeast China, and was originally a wild weed. However, it is also a fairly long-standing Chinese medicinal herb, with the main medicinal part being the flower heads of Inula japonica, mainly used to treat cough and asthma with excessive phlegm, as well as chest and diaphragm distension and fullness. It has effects such as eliminating phlegm and promoting water movement, and treating phlegm-fluid retention. So how should Inula japonica be planted? Below, the editor brings you the cultivation techniques for Inula japonica. Let's take a look together!

1. Site Selection and Land Preparation

Inula japonica does not have high soil requirements and can grow well in various plots of soil, such as hillside land and riverside land. However, different soil properties will have a certain impact on the growth of Inula japonica. When planting artificially, choose soil with normal drainage and irrigation, sufficient fertility, and rich organic matter for planting. Only in this way can the growth of Inula japonica be fully guaranteed and the yield and quality of Inula japonica be improved. After selecting the land, carry out land preparation work well. The depth of land preparation must not be less than 25 cm, then apply about 3500 kg of decomposed farmyard manure per mu as base fertilizer, level the land and make beds.

2. Propagation Methods

There are many propagation methods for Inula japonica, among which the most commonly used propagation method is mainly seed propagation. First, we need to control the sowing row spacing well, control it at about 28 cm, dig the sowing furrows, and then evenly scatter the seeds into the sowing furrows. Then cover with fine soil, press it firmly and tread it tightly, and cover with a layer of rice straw to improve the soil's water and fertilizer retention. Seedlings can emerge in about 3 weeks. After the seedlings emerge, remove the rice straw to ensure the soil remains moist while preventing hardening, and avoid the rampant growth of weeds. If weeds appear, weed control work also needs to be done well to prevent weeds from competing for nutrients and affecting seedling growth.

3. Field Management

When the seedlings grow to about 4 cm, do the thinning work well, remove weak and dead seedlings, and retain strong-growing seedlings. Then when they are about 7-8 cm, set the plant spacing at about 17-18 cm for final thinning, and fill missing hills with healthy seedlings of the same growth. In summer each year, pay attention to intertillage and weeding, and topdress fertilizer promptly after each weeding, mainly with decomposed farmyard manure. Then after each harvest, carry out hilling work. Pay attention to observing soil moisture. Water promptly when it is too dry. When prolonged rainy weather causes water accumulation or when too much watering occurs, do loosening management well to prevent soil hardening, which can cause seedling root rot, reduce water evaporation, and do drainage work well.

4. Pest and Disease Control

Inula japonica can grow for many years. Although the incidence of pests and diseases is not high, after more than 3 years of planting, some old roots of the plants gradually age, and disease resistance also declines. Therefore, the incidence of pests and diseases will also rise, and wilt disease, root rot, and others are very likely to occur. We should strengthen drainage and irrigation work, pay attention to drainage, enhance the growth vigor of Inula japonica, and improve its growth ability. After disease occurs, promptly pull out diseased plants, then check the specific disease and carry out targeted control. For example, for root rot, pesticides such as carbendazim can be used for spraying control.

The above is a brief introduction to the cultivation techniques of Inula japonica. The growth ability of Inula japonica is relatively strong, but when planted artificially, there will inevitably be some differences from the wild environment. Therefore, when planting, we still need to do management work well to avoid some adverse phenomena in Inula japonica. That is all for today's introduction. This article is for reference only.
