How to Grow Aconitum kusnezoffii? Cultivation Methods for a Precious Chinese Medicinal Herb
Aconitum kusnezoffii is a perennial herbaceous plant of the Ranunculaceae family and a relatively precious Chinese medicinal herb. Its main medicinal part is the tuber. It has a very wide planting area in our country, and the cultivation benefits of Aconitum kusnezoffii are very good. Below is an introduction to the cultivation methods of the “precious Chinese medicinal herb” Aconitum kusnezoffii!
1. Land Selection and Preparation
The root system of Aconitum kusnezoffii is widely distributed and relatively deep, and it is very poor at tolerating both waterlogging and drought. Therefore, to achieve high yield and high quality when growing Aconitum kusnezoffii, it is necessary to choose soil suitable for its growth. Deep, loose, fertile soil rich in organic matter with good drainage and irrigation is relatively suitable for the growth of Aconitum kusnezoffii. After selecting the land, deep plowing and intertillage should be carried out in a timely manner, field weeds should be removed, and after sun exposure for about 1 week, disinfection work should be done well to reduce the incidence of pests and diseases. Then field beds should be made, and the specifications of the field beds should be planned according to the terrain to ensure that the bed surface is flat and loose, suitable for the growth of Aconitum kusnezoffii.
2. Timely Sowing
Usually, the sowing time for Aconitum kusnezoffii is around mid-December after the Start of Winter each year. Before sowing, sowing furrows should be opened on the bed surface, and then the seed tubers should be sown in the furrows with the bud eyes facing upward. The number of planting rows per field bed must not exceed two rows. The sowing density and sowing amount should be well controlled. The sowing amount will vary according to the weight of the tubers. After sowing, an appropriate amount of farmyard manure should be prepared according to the planting area, mixed into the soil, and evenly applied in the furrows. After fertilizing, fine soil should be covered to improve the soil's water and fertilizer retention, promote seed germination and seedling emergence, and increase the survival rate.
3. Water and Fertilizer Management
After sowing, the soil should be kept moist to promote seed germination, which is beneficial for uniform and strong seedlings. If drought occurs, in order to ensure the growth of the seedlings, plastic film should be appropriately covered on the bed surface to improve soil water retention. After the seedlings emerge, the covering can be gradually removed. Too much or too little water will affect the growth of Aconitum kusnezoffii, so we should control water drainage and irrigation well according to the weather and soil. Then, about half a month after seedling emergence, topdressing should begin. Topdressing should follow the principle of multiple applications in small amounts, using decomposed farmyard manure. When the plants grow to about 1 m, a second topdressing should be carried out along with appropriate insecticide and fungicide treatment, to promote tuber enlargement while doing a good job in pest and disease prevention and control.
4. Field Management
Aconitum kusnezoffii is a vine plant, so during the first fertilization, support work should also be done well. If seedlings suffer from disease, the diseased seedlings should be removed promptly and replanted. During the growth process, in order to avoid excessive water, reduce pests and diseases, and promote the growth of Aconitum kusnezoffii, intertillage and hilling should be done well. Appropriate hilling can promote the growth of adventitious roots of Aconitum kusnezoffii and improve soil permeability. Also, when Aconitum kusnezoffii begins to bud, topping should be carried out in a timely manner. When topping, care must be taken not to damage the plant or leaves, so as to avoid affecting leaf photosynthesis, reduce nutrient consumption, and create a good growth environment for Aconitum kusnezoffii.
The above is a brief introduction by Tuliu.com to the cultivation methods of Aconitum kusnezoffii. During cultivation, work such as leaf picking, pruning, and pest and disease control should also be done well. It should be noted that Aconitum kusnezoffii is toxic, and untreated Aconitum kusnezoffii must never be eaten. In severe cases, it can cause the consumer's death.
