How to manage the field of Coptis chinensis

Coptis chinensis is a valuable traditional Chinese medicine. With the increase of market demand, the scale of artificial cultivation is also expanding. Now it is mainly distributed in Sichuan, Guizhou, Hunan, Hubei and other places in China. If Coptis chinensis wants to be high-yielding, field management is the key, so how can we carry out field management? Let's learn about it together.

1. Seedling stage management

After sowing Coptis chinensis, we should timely remove the plastic film or straw covered in the upper layer of the soil, so as not to affect the growth of Coptis chinensis seedlings. During this period, we should observe the soil moisture in the field and water it reasonably to promote the growth of seedlings. When the seedlings grow out of two or three true leaves, they should begin to grow seedlings. In addition, we have to build a shade shed before the emergence of Coptis chinensis seedlings to avoid excessive light intensity and sunburn seedlings after emergence.

2. Replenish seedlings and plant

Generally speaking, when the seedlings of Coptis chinensis grow to about 8 to 15 centimeters, we will begin to uniform, transfer and replenish the seedlings, which is simply planting. When we transplant seedlings, we should first homogenize some of the seedlings in the seedling field, and then plant the rest of the seedlings, but the phenomenon of dead seedlings will inevitably occur in the process of planting, so we need to observe the survival of the seedlings every period of time and replenish the seedlings in time to ensure the uniform seedlings in the field.

3. Ploughing and weeding

During the seedling period, Coptis chinensis needs to carry out at least three to five times of intermediate ploughing and weeding, while after the seedlings are transplanted, it usually only needs two to three times. In order not to affect the growth of Coptis chinensis, we usually carry out shallow ploughing in the case of soil consolidation after the rainy season, so that the roots of Coptis chinensis will not be hurt. Secondly, when there are more weeds, we can manually pull out the weeds, or ploughing, to remove the weeds and reduce the consumption of nutrients.

4. Scientific water and fertilizer

During the growth of Coptis chinensis seedlings, we need to apply fertilizer three times, mainly with feces and urine for watering, and to control the concentration of feces and urine, preferably at a low concentration, so as not to burn the seedlings. After transplanting, we need to first apply dilute manure water, wait until spring with available nitrogen fertilizer topdressing, and then wait until autumn topdressing, autumn fertilizer is mainly farm manure. The amount of fertilizer applied per mu should not be too large, but it is also necessary to ensure that the growth demand of Coptis chinensis is generally controlled at about 3000 jin.

5. Adjust shading

For the growth of Coptis chinensis, we need to build a shade, but we also need to adjust the light intensity reasonably. During the first to third years of Coptis chinensis growth, there is not much demand for light, so we should always check whether the shade is defective and repair it in time. Wait until the fourth year, you can slowly reduce the shade, increase the light intensity, if the light is too weak, it will also affect the normal growth of Coptis chinensis.

The field management technology of Coptis chinensis planting is introduced here. I hope it can be helpful to you. At the same time, I wish you all a pleasant journey in the later stage of planting.
