Key points of cultivation and management of Arnebia euphratica

Arnebia is a kind of herb of Arnebiaceae, the plant is about 1 meter high, is a very common weed, but also we often use traditional Chinese medicine. Arnebia has the effects of cooling blood and promoting blood circulation, clearing heat and detoxification, mainly used in the treatment of vaginitis, hepatitis and other diseases, its prevention and treatment effect is more obvious. Now Arnebia also has a certain cultivation area, so how to manage it when cultivating Arnebia? The following editor brings you the key points of the cultivation and management of purple grass, let's have a look!

1. Ploughing and weeding

Whether it is to take the method of seedling transplanting or direct seeding, when the seedlings grow to about 5 cm, we should do a good job of ploughing and weeding to improve soil permeability and prevent soil consolidation. Avoid too many weeds to rob the growth and nutrition of Arnebia seedlings and ensure that there are no weeds in the field. However, it should not be too deep when ploughing, so as to prevent damage to the roots of seedlings and affect the nutrient absorption of Arnebia. Usually, the number of times of weeding and ploughing should not be less than 3 times a year. Then it is necessary to do a good job of soil cultivation in winter to prevent lodging and improve the cold resistance of Arnebia.

2. The seedlings are fixed

The work of determining seedlings is very important for the growth of Arnebia euphratica to ensure that each seedling has sufficient growth space and promote the robust growth of seedlings. When the first intertillage is carried out, it needs to be combined with the work of interplanting. The distance between plants should be controlled at about 5-6 cm, following the principle of keeping the strong and removing the weak. Then when the seedlings grow to about 16 meters, determine the seedlings in time, the plant distance should not be less than 8 centimeters.

3. Water management

Arnebia has a great demand for water, and in the process of planting, water has a great influence on the growth of Arnebia. In the dry season such as spring and summer, it is necessary to water in time to promote the water absorption of seedlings and prevent them from withering and withering due to lack of water. However, the demand for Arnebia tomentosa will gradually decrease with the increase of growth age. After adulthood, it can be watered less or even not watered, and in rainy days, we should pay attention to do a good job of drainage to prevent purple grass waterlogging.

4. Proper topdressing

Nutrition is also an indispensable substance for the growth of Arnebia frutescens, which needs to be fertilized in time after weeding. According to the different growth stages of Arnebia frutescens, the dosage and nutrition ratio should be controlled. For example, in the seedling stage, fertilizer should be mainly nitrogen fertilizer, phosphorus and potassium fertilizer. When the seedlings grow to about 32 cm, it is necessary to apply rotten farm manure to 2000kg/ mu, and the amount of topdressing should be increased appropriately with the increase of growth years.

5. Pick buds in time

Because the flowers of Arnebia do not have much use value, and will consume too much nutrients. Therefore, during the budding stage of Arnebia, we should pay attention to remove the buds in time to prevent excessive nutrient consumption, concentrate nutrients with the roots of Arnebia, promote the growth of roots and improve the quality and yield of roots. Especially for adult plants, the nutritional demand of adult plants becomes larger, and more effects are needed if they bloom, so bud picking is very important.

The above is a brief introduction to the key points of the cultivation and management of Arnebia. The cultivation of Arnebia is actually relatively simple, but the management work is still very important. Therefore, we must pay attention to do some basic work to ensure the healthy growth of Arnebia. That's all for today's introduction. This article is for reference only. I hope it can help you all.
