How to plant it well before Baiqian

Baiqian is also called Baiqian, cough medicine, Xiaojie grass, etc. It is a kind of traditional Chinese medicine, mainly with its dry rhizome and root as medicine. At present in China's Zhejiang, Jiangsu, Jiangxi, Hunan, Guizhou and other places are planted. Its main function is to eliminate phlegm, cough, for the treatment of cough sputum, chest full asthma and other symptoms. So, do you know how to plant white flowers? Let's learn about its high-yield cultivation techniques together.

1. Field preparation

It has the characteristics of warm, wet and drought resistance, and is generally suitable for planting in plots with deep soil layer, sufficient soil fertility and rich humus content. Secondly, the planting land terrain should be relatively flat, open terrain, sufficient light, abundant water resources, convenient irrigation and drainage, etc. When preparing the soil, it should be turned over many times, and the base fertilizer should be heavily applied, mainly based on decomposed livestock manure or compost, and applied together with phosphorus fertilizer. After fertilization, deep ploughing is carried out again, base fertilizer is mixed evenly, and finally, according to the topography of the planting land, reasonable furrows are made for the ridge, and the cultivation can be carried out by raking the flat ridge surface.

2. Cultivation methods

There are generally two planting methods of Plantago asiatica, namely seed propagation and seed stem seedling transplantation. Regardless of the propagation method, the best time to plant it is from late March to early April of each year. Planting depends on the fertility of the soil, and is generally done according to a standard spacing of thirty to forty centimeters between rows and thirty centimeters between plants. Seed reproduction needs to be soaked in warm water to germinate, then planted, and covered with soil, but also need to cover straw or plastic film, so as to improve the emergence rate. The stem seedling transplantation is to select 2 or 3 rhizomes below the rhizosphere for planting, and after planting, it is necessary to irrigate enough root water, which can improve the survival rate.

3. Field management

After the white seeds emerge, we should remove the straw or film and do a good job of thinning and replenishing the seedlings. Secondly, the growth rate of white plant in seedling stage is very slow, so we should carry out cultivation and weeding from time to time to promote nutrient absorption and enhance soil permeability, so as to improve the growth rate of white plant. When the seedlings grow to about 15 cm, we need to carry out the first topdressing. The topdressing for tooth decay is mainly urea. In the later period, it should be applied once every half month. The amount of fertilizer should not be too large. When September is the time for fertilization, we need to use phosphate fertilizer or cake fertilizer, compound fertilizer and other fertilizers to promote the yield of white before. Also, 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 white flower is relatively strong, and its most common disease is nematode disease, which mainly damages the roots of white flower, seriously affecting the yield of white flower. Before the disease occurs, we should pay attention to crop rotation, improve seeding and scientific fertilization to enhance plant resistance, and do a good job in field hygiene, which can play a very good preventive effect. In the early stages of the disease, we can use dibromochloropropane to poison. There is also white before the harm by aphids is also relatively large, it has a greater impact on the yield and quality of white before, you can use dimethoate EC control.

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