How to fertilize Pinellia ternata? The latest fertilization technique and method tutorial

Pinellia ternata is a common plant that grows in southern China, and its underground tubers are an important traditional Chinese medicinal material, with its own unique role in traditional Chinese medicine treatment. In the past, wild Pinellia ternata was dug from the mountains for medicinal use, but its reproductive quantity is limited and cannot meet the huge demand, so in recent years artificial cultivation has also begun to be advocated. But how to fertilize during cultivation to promote growth requires someone to introduce it.

1. Fertilizer requirement characteristics

The rhizomes of Pinellia ternata mainly grow in the shallow soil layer within 10 cm, so when fertilizing it is not necessary to fertilize with deep plowing, and it is only necessary to fertilize in the soil layer about 5 cm below the soil surface. Pinellia ternata likes fertilizer and has a relatively large demand for fertilizer. Its fertilizer requirements differ at different stages, and the amounts also differ, so it can be applied accordingly. Pinellia ternata mainly roots through its tubers, so it is best to apply fertilizer in water, as it is easily absorbed.

2. Fertilization technique

Base fertilizer is applied before planting. Generally, it is best to use farmyard manure made by composting and decomposing fallen leaves, crop straw, and animal manure together. About 500 to 600 jin of base fertilizer is applied per mu, which can greatly improve the soil structure. Topdressing can be done multiple times a year, and it is best to determine it according to the growth situation. Generally, topdressing is done once at the seedling stage to promote the stable growth of young seedlings and promote the aboveground part. In summer, there will be heavy rainfall or irrigation, which will carry away the nutrients in the soil, so a large amount of topdressing is needed to supplement nutrients, mainly phosphorus and potassium fertilizer and calcium fertilizer, while also supplementing soil trace elements to meet the needs of tuber growth. The third topdressing is between September and October. At this time, some specially prepared fertilizer needs to be used specifically to ensure tuber expansion, about 1 to 3 jin applied per mu. When fertilizing, it is necessary to do so at a distance of 10 cm from the base of the stem so as not to burn the stem.

3. Fertilization method

Generally, cultivation is done in rows on ridges, so the most common fertilization method is to dig two small ditches about 5 cm wide on both sides of the ridge rows for fertilization, which is convenient and fast, and the fertilization is uniform. Or dig small pits beside each plant for hole application, which gives the best and most complete absorption. Or dissolve it in water and use it together with irrigation, which takes effect fastest.

The artificial cultivation time of Pinellia ternata is not long, so in terms of various management and fertilization techniques when it is not produced, there is still no relatively complete experience, and everything needs to be accumulated through practice. But it is also necessary to master the existing experience.
