High-yielding cultivation techniques of Perrin

Eupatorium is also called chicken bone incense, water incense, etc., is a plant of Compositae, which has a long history of cultivation in China. The whole herb of Eupatorium can be used as medicine, which has various effects such as clearing away heat and detoxifying, eliminating dampness and stopping vomiting. It has a wide distribution range in our country, and its planting area is also very large. So how should Perrin be planted specifically? Today, Xiaobian brought you Perrin's cultivation techniques. Let's take a look at them together!

1. Land selection and preparation

The growth ability of Eupatorium fortunei is relatively strong, and it can grow normally in various soils. However, artificial planting, or to choose sufficient fertility, soft and transparent, sufficient light and good irrigation soil, more suitable for the growth of Eupatorium. Do not plant in potholes uneven, easy to accumulate water on the saline-alkali land. It is very unfavorable to the growth of Eupatorium. After selecting the land, we should do a good job of soil preparation, turn it deeply about 30 cm, and carry out comprehensive and thorough disinfection. Then apply sufficient decomposed farm manure as base fertilizer according to the soil area, and then prepare for planting.

2. Breeding methods

The most common method of propagation is rhizome propagation, which is usually carried out in winter and spring every year. Before planting, first select the rhizome with normal color, strong growth and full bud eyes as the mother stem, and then cut it into small pieces of about 7-9 cm. Then do a good job of disinfection, and then control the planting density to dig a good planting hole, planting it into the planting hole. After planting, we should strengthen management, cover fine soil, irrigate enough water, and improve the rooting and emergence rate of rhizomes. Generally under normal management, spring sowing about half a month or so can emerge.

3. Field management

When the seedlings break the soil and grow to about 12 cm, they should do a good job of thinning seedlings. The seedlings in each planting hole should not exceed 2, and the holes lacking seedlings should be supplemented with healthy seedlings of the same growth in time. In the seedling stage, we should also do a good job of intertillage and weeding, follow the principle of leaving no grass, but stop weeding after closing the ridge. Then do a good job of water and fertilizer. When the seedlings grow to about 8 cm, they should start topdressing, and then topdressing again when they grow to about 21 cm. After harvesting the first crop of seedlings, apply heavy fertilizer, water once after each fertilization, keep the soil moist, water more in dry season, but the water should not be too much, and drain well in rainy days or ponding.

4. Pest control

The prevention and control of diseases and insect pests is a point that should be paid attention to every crop planted. Diseases and insect pests will harm all parts of the plant and seriously hinder the growth of Eupatorium. Therefore, we should pay attention to prevention work when planting. 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 diseases of Eupatorium fortunei are mainly root rot, which is easy to occur under the conditions of low-lying ponding, high temperature and high humidity. Therefore, we should control the moisture and temperature in the field to prevent the accumulation of water from affecting the growth of Perrin.

The above is a simple introduction to the cultivation technology of Perrin. The growth adaptability of Perrin is very strong. However, in different environments, its yield and quality will be different, so we should control the planting conditions to create a good growth environment for Perrin.
