How to plant the latest Baiqian?

Baiqian is also known as Euphorbia angustifolia, cough medicine, Xiaojie grass, etc., it is one of the traditional Chinese medicine, mainly with its dry rhizome and root medicine. At present, it is planted in Zhejiang, Jiangsu, Jiangxi, Hunan, Guizhou and other places in China. Its main function is to eliminate phlegm and relieve cough, and it is used to treat symptoms such as cough, phlegm, chest fullness and shortness of breath. So do you know how to plant Baiqian? Now let's learn about its high-yield cultivation techniques.

1. Daejeon preparation

Baiqian has the characteristics of warmth, moisture and drought tolerance, so it is generally suitable for planting in plots with deep soil layer, sufficient soil fertility and rich humus content. Secondly, the topography of the planting land should be relatively flat, with open terrain, sufficient light, abundant water resources, convenient drainage and irrigation, and so on. Soil preparation should be done many times, and base fertilizer should be re-applied, mainly rotten livestock manure or compost, together with phosphate fertilizer. After fertilization, turn deeply again, mix the base fertilizer well, and finally, according to the topography of the planting area, reasonably open the ditch to make the border, rake the border surface to carry on the cultivation.

2. Planting method

There are generally two planting methods before white, namely seed propagation and seed stem seedling transplanting. No matter which breeding method is used, the best time to plant it is from the end of March to the beginning of April every year. The sight of planting needs to be determined according to the fertility of the soil, generally according to the standard that the row spacing is 30 to 40 cm and the plant spacing is 30 cm. Seed reproduction needs to soak the seeds in warm water to accelerate germination, and then plant them, and after covering the seeds with soil, they also need to be covered with straw or plastic film, which can improve the emergence rate. On the other hand, the transplanting of stem seedlings is to choose 2 or 3 nodes of rhizomes below the rhizosphere to plant, and it is necessary to irrigate enough fixed root water after planting, which can improve the survival rate.

3. Field management

After the emergence of Baiqian seeds, we should remove the straw or film, and do a good job of replenishing seedlings. Secondly, the growth rate of Baiqian in the seedling stage is very slow, so we should carry out irregular ploughing and weeding to promote the absorption of nutrients and enhance soil permeability in order to improve the growth rate of Baiqian. When the white seedlings grow to about 15 centimeters, we need to carry out the first topdressing, which is mainly urea for tooth decay, and once every half a month in the later stage, the amount of fertilizer should not be too large. When fertilization is carried out in September, we need to use phosphate fertilizer or cake fertilizer, compound fertilizer and other fertilizers to promote pre-white yield. In addition, we should pay attention to the management of water in the field, keep the soil moist, and pay attention to drainage.

4. Disease and pest control

In fact, the resistance of Baiqian is relatively strong, and its most common disease is nematode disease, which mainly harms the roots of Baiqian and seriously affects the yield of Baiqian. Before the onset of the disease, we should pay attention to crop rotation, improve sowing and scientific fertilization to enhance plant resistance and improve field sanitation, which can play a very good preventive effect. In the early stages of the disease, we can use dibromochloropropane for poisoning. In addition, Baiqian is also harmed by aphids, which has a great impact on the yield and quality of Baiqian, so dimethoate EC can be used for prevention and control.

The above is the planting method of Baiqian that the editor brings to you today. I hope it can help you to plant Baiqian and those who want to plant it. Thank you for your long-term support and encouragement to the editor. Your reading is an affirmation of the editor's work. At the same time, I wish you all a smooth planting in the new year.
