The latest tutorial on the newest cultivation techniques for Centipeda minima
Centipeda minima is a traditional Chinese medicine, commonly growing in rural areas, and it got its name because even geese will not eat it. It has the effects of dispelling wind-cold, clearing the nasal passages, relieving cough, detoxifying, and relieving itching, and is often used to treat rhinitis. So how should it be cultivated? Let's take a look together.
1. Land selection and soil preparation
Centipeda minima has low requirements for soil and can adapt to various soils. It is suitable for planting in loose, fertile sandy loam with good drainage. Before planting, the land should be prepared by deep plowing and breaking up the soil. Because the growth cycle of Centipeda minima is short, basal fertilizer needs to be applied heavily. The basal fertilizer is mainly farmyard manure, and 3000-4000 kg of decomposed farmyard manure can be applied per mu, together with an appropriate amount of nitrogen, phosphorus, and potassium fertilizer. After mixing it into the soil, make beds according to the terrain.
2. Seed treatment
The seeds of Centipeda minima are relatively small and are also wrapped inside the fruit. Before sowing, the fruit must first be collected. After collecting the seeds, dry them in the sun, rub off the fruit skin, and take out the seeds for later use. There is a waxy substance on the outer layer of the seeds, which affects water absorption by the seeds and makes them difficult to germinate. Therefore, when sowing, in order to improve the germination rate, the seeds should be treated by soaking them in water to remove the waxy layer on the outside. Then mix the seeds evenly with fine soil or fine sand and prepare to sow.
3. Sowing
Sowing can be done in spring or autumn. Spring sowing is generally for commercial use, while autumn sowing can be for both commercial use and seed retention. Spring sowing is carried out from March to May, and autumn sowing is carried out in mid-to-late August. Sowing can be divided into drilling and broadcasting methods. Drilling requires opening shallow furrows on the bed surface at a row spacing of 25-30 cm, evenly scattering the seeds into the furrows, and then covering with soil. Broadcasting requires preparing a seedbed, evenly scattering the seeds on the seedbed, and then covering with a thin layer of soil. Generally, broadcasting consumes more seeds than drilling.
4. Field management
After sowing, water frequently to keep the soil moist, but also be careful about water accumulation, so as not to cause the seeds to rot or damage the seedling roots. Drain promptly after rain. At a certain stage of growth, thin and finalize the seedlings in time. After planting, water management is extremely critical. Both drought and waterlogging must be prevented, and irrigation can be stopped during the fruiting period. During high temperatures, irrigate in the drainage ditches, which can achieve the effect of lowering the temperature and preventing the plants from being scorched.
