Cultivation Techniques of Delphinium

Swift grass is a perennial herb, which makes its flower shape unique, much like a small swallow. It is cultivated in various provinces of our country. Its roots and seeds can be used as medicine, and its seeds have the effect of vomiting and purging. External use can kill insects and cure scabies. The root can cure injury. So how to grow delphinium? Let's take a look.

1. Land selection and preparation

Swallows like sunny, cool climate conditions, cold-resistant, afraid of high temperature, suitable for growing in deep soil, loose and fertile soil, good drainage sandy soil, it is suitable to grow in acidic soil. After selecting the land, the soil was ploughed for many times to make the soil weathered fully, and the base fertilizer was applied according to the soil fertility. The base fertilizer was mainly organic fertilizer and farm manure, with an appropriate amount of compound fertilizer. After shaping and raking, make beds or ridges, make drainage ditches, and wait for planting.

2. Methods of reproduction

Swallow grass is often propagated by sowing, either in spring or autumn, and it is suitable for spring sowing in the north, which is generally carried out in March. Before sowing, it is necessary to refrigerate the yield, break dormancy and improve the germination rate. Generally choose the method of direct seeding, sowing in trenches on the border surface, covering soil and watering after sowing, and sprouting in about 15-20 days. Autumn sowing time is from August to September, when the temperature is suitable, the seeds do not need to germinate, and germinate about 15 days after sowing. Cuttings and ramets can be used for propagation in spring planting, which can improve production efficiency. Cutting is generally carried out in spring, and individual plants can be carried out in spring and autumn.

3. Transplanting

Swallow is a straight-root plant and is not resistant to transplanting, so direct seeding is generally suitable for production, and if it is to be carried out, it is usually carried out when the plant grows 3-4 leaves. It is necessary to pay attention to transplanting with soil, and be careful not to touch the soil around the root system, otherwise the survival rate of the plant is low.

4. Field management

In the growing period of swallow, topdressing is needed once every semimonthly, mainly nitrogen fertilizer to promote the rapid growth of plants, and 2-3 times of topdressing at flowering stage, mainly phosphorus and potassium fertilizer. In addition, it is necessary to keep the soil moist for a long time, water in time when you love to work, and drainage measures in the rainy season to avoid stagnant water and rotten roots. Its inflorescence is tall, so it is necessary to take good measures to cultivate the soil during the flowering period to avoid plant lodging. When the plant grows to 30 cm, it is also necessary to draw a net between the rows to prevent lodging.
