The latest course of high-yield cultivation techniques of Perrin

Perrin, also known as chicken bone incense, water incense, etc., is a plant of Compositae, which has a long history in China. Peran's whole herb can be used as medicine, with heat-clearing and detoxification, dampness and anti-vomiting and other effects. It has a wide range of distribution in China, and its planting area is also very large, so how should Perrin plant it? Today, the editor brings you Perrin's cultivation techniques. Let's take a look!

1. Land selection and preparation

Perrin has strong growth ability and can grow normally in all kinds of soil. However, artificial planting, or to choose sufficient fertility, soft and transparent, adequate light and good drainage and irrigation soil, more suitable for the growth of Perrin. Do not plant on saline-alkali land that is uneven and prone to stagnant water. It is very disadvantageous to the growth of Perrin. After selecting a good site, it is necessary to do a good job of soil preparation, turn it over about 30 centimeters deep, and carry out comprehensive and thorough disinfection. Then according to the soil area, apply sufficient mature farm manure as base fertilizer, and then prepare the bed for planting.

2. Methods of reproduction

Perrin's most commonly used method of reproduction is rhizome propagation, which is usually carried out in winter and spring every year. Before planting, you should first choose the rhizome with normal color, strong growth and full bud eyes as the mother stem, and then cut it into small segments of about 7-9 cm. Then do a good job of disinfection, and then control the planting density, dig a good planting hole, and plant it into the planting hole. After planting, the management should be strengthened, fine soil should be covered, enough water should be watered, and the rooting rate of rhizome should be improved. Generally under normal management, seedlings can emerge after sowing in spring for about half a month.

3. Field management

When the seedlings grow to about 12 cm, it is necessary to do a good job of interplanting seedlings, leaving seedlings in each planting hole should not exceed 2, and the healthy seedlings with the same growth should be made up in time at the mouth of the lack of seedlings. In the seedling stage, we should also do a good job in weeding and weeding, follow the principle of not leaving a single grass, but stop weeding after the ridge is closed. Then do a good job of water and fertilizer, start topdressing when the seedlings grow to about 8 centimeters, and then fertilize again when the seedlings are about 21 centimeters. Apply heavy fertilizer after harvesting the first crop of seedlings, water once after each fertilization, keep the soil moist, water more in dry season, but not too much water, and do a good job of drainage in rainy days or stagnant water.

4. Pest control

The prevention and control of diseases and insect pests is a point that every crop should pay attention to. Diseases and insect pests will harm all parts of the plant and seriously hinder the growth of Perrin. Therefore, when we are planting, we should pay attention to the prevention work, and when preventing diseases and insect pests, we should pay attention to the occurrence law of diseases and insect pests and carry out symptomatic prevention and control. For example, the common disease of Perrin is mainly root rot, which is easy to occur under the condition of low-lying water, high temperature and high humidity. Therefore, we should control the moisture and temperature in the field to prevent stagnant water from affecting the growth of Perrin.

The above is a brief introduction of Perrin's cultivation techniques, Perrin's growth adaptability is very strong. However, growing in different environments, the yield and quality will be different, so we should control the planting conditions to create a good growth environment for Perrin. That's all for today's introduction. This article is for reference only. I hope it can help you all.
