A Full Analysis of the Latest Planting Methods for Flemingia (Qianjinba)
Flemingia (Qianjinba) is a kind of Chinese medicinal herb, also called Tuhuangji and Niudali, and in some places it is also called Qianjindiao. It can dispel rheumatism and remove blood stasis and toxins, and is mainly used to treat rheumatic pain, chronic nephritis, traumatic injuries and jaundice and other diseases. As its efficacy and effects are gradually being explored, wild Qianjinba can no longer meet the market demand, so artificial cultivation is needed. So how should Qianjinba be planted? Let's learn its planting methods together below.
1. Seed selection and land preparation
Qianjinba is mainly divided into large-leaf varieties and small-leaf varieties. At present, the small-leaf variety of Qianjinba is more popular on the market than the large-leaf variety, and its yield and quality under artificial cultivation are also better. So if we are going to plant it, we generally choose the small-leaf variety of Qianjinba. Qianjinba is suitable for growing in a warm environment with sufficient light, and has the characteristics of being drought-tolerant and afraid of waterlogging. The soil of the planting site should have sufficient fertility and a complete drainage and irrigation system. Deeply plow the land, break up the clods of soil, open furrows and make beds, level the bed surface, apply sufficient base fertilizer, and spray herbicide about one week before sowing to clear the weeds in the field.
2. Scientific sowing
The best time to plant Qianjinba is during the two months of March to April each year. Next, August is also suitable for planting, but the yield and quality are not as good as spring sowing. Before sowing, the seeds need to be soaked in warm water and taken out after forty-eight hours. During the soaking process, the water needs to be changed twice. After two-thirds of the seeds have fully absorbed water, they can be sown. When sowing, carry out hole sowing with a row spacing of 20 cm and a plant spacing of 15 cm.
3. Field management
After the seedlings emerge, observe the growth of the seedlings in the field and carry out thinning and replanting in time. During the process of thinning and replanting, we should clear away all the weeds visible in the field. When the weather is relatively dry, water in time, while during continuous rainfall or the rainy season, attention should be paid to drainage. When the Qianjinba seedlings grow to about 20 cm, apply a liquid fertilizer once to promote the growth of the seedlings. Then every half a month to one month, carry out topdressing, mainly with compound fertilizer. During its entire growth process, generally three topdressings are needed. At the second topdressing, the terminal buds should be removed, and reasonable weeding should be carried out.
4. Flower thinning to promote production
The medicinal part of Qianjinba is its root, so during its growth process, the main goal is to promote the growth of the root. Therefore, on the basis of fertilization, we need to apply flower thinning management to reduce nutrient loss, so that nutrients are concentrated in the root of Qianjinba and promote the enlargement of the root. So during the flowering period, some flower buds should be knocked off. This can be done by manual removal, or by spraying ethephon for flower thinning.
5. Disease control
Qianjinba has strong disease resistance and basically has no pests or diseases, but in hot and rainy seasons, root rot and anthracnose are very likely to occur. For root rot, we can prevent and control it by clearing drainage ditches, applying more plant ash, and using Bordeaux mixture. Anthracnose can be prevented and controlled with zineb solution, and of course Bordeaux mixture is also quite effective. The main pest is aphids, which can be poisoned by spraying dimethoate,
