The latest course on the planting techniques and methods of delphinium

Delphinium is a perennial herb, so that its flower shape unique, similar to a small swallow named, in China's provinces with cultivation, its roots and seeds can be used as medicine, seeds have emetic, purgative effect, external use can kill insects, scabies, roots can cure traumatic injuries. So how should delphinium be grown? Let's take a look.

1. Land selection and preparation

Delphinium like sunny, cool climate conditions, cold, afraid of high temperature, suitable for growth in deep soil layer, loose fertile soil, good drainage of sandy loam, acid soil planting is appropriate. After selecting the land, plowing it for many times to make the soil naturally weathered sufficiently, applying base fertilizer according to the fertility condition of the soil, the base fertilizer is mainly organic fertilizer and farm manure, and matching appropriate compound fertilizer. After shaping and leveling, make ridges or ridges, make drainage ditches, and wait for planting.

2. Breeding methods

Delphinium multi-use sowing for reproduction, spring or autumn sowing can be, the north suitable for spring sowing, generally in March, before sowing to cold storage yield, break dormancy, improve germination rate. Generally choose direct seeding method, in the ridge surface trenching sowing, after sowing soil watering can, about 15-20 days can germinate seedlings. Autumn sowing time in August-September, when the temperature is appropriate, seeds do not need to germinate, about 15 days after sowing germination. Cuttings and ramets can be used for propagation in spring planting, which can improve production efficiency. Cuttings are generally carried out in spring, and ramets can be carried out in spring and autumn.

3. Transplanting

Delphinium is a straight-root plant, which is not tolerant of transplanting, so it is generally suitable for direct seeding in production. If it is to be carried out, it is generally carried out when the plant grows 3-4 leaves. It is necessary to pay attention to transplanting with soil, but also pay attention not to touch the soil around the root system, otherwise the survival rate of the plant is low.

4. Field management

In the growth period of delphinium, topdressing is needed once every half month, mainly nitrogen fertilizer, to promote rapid growth of plants, and topdressing is needed 2-3 times in flowering period, mainly phosphorus and potassium fertilizer. In addition, it is necessary to keep the soil moist for a long time. When you love to work, you should water it in time. In the rainy season, you should also take drainage measures to avoid standing water and rotten roots. Its inflorescences are tall, and soil cultivation measures should be taken at flowering stage to avoid lodging of plants. When planting grows to 30 cm, nets should be fixed between rows to prevent lodging.

The above is an introduction to delphinium planting technology. I hope it can help you. If you want to know more about it, please pay attention to us.
