Matters needing attention in planting Coptis chinensis

Coptis chinensis is a very common traditional Chinese medicine. It has strong medicinal properties, heavy smell and bitter taste. Although we may never have seen it or tasted it, we all know that it is bitter. After all, there is an old saying that has been circulating until now, that is, dumb people eat coptis chinensis and suffer unspeakably. Therefore, everyone knows that coptis chinensis is bitter. However, due to its high value, it exists in major traditional Chinese medicine stores and western medicine ingredients. Moreover, many people now make their fortune by planting coptis chinensis. So coptis cultivation needs to pay attention to what, how to high yield, the following by the pro-agricultural network to tell you.

1, planting time

The seasonality of Coptis chinensis planting is not particularly obvious, but it also needs attention when planting. Normally, coptis can be planted in spring, summer and autumn, but it cannot be planted in winter because the temperature in winter is too low to sprout seeds. In spring, we usually plant in early March, in summer, we plant in early May, and in autumn, we plant in late October to mid-November. These time periods are most suitable for germination of Coptis chinensis seeds, followed by transplanting. Transplanting is generally best from March to April, when the survival rate is higher.

2. Planting conditions

Coptis chinensis does not need a lot of light to grow, so it is best to plant it in a relatively cloudy place, but the market will have sunlight but not direct sunlight, followed by a certain slope of planting land to facilitate drainage, and then try to choose sandy land with more organic matter and complete soil structure, so that the permeability, fertilizer storage and water storage of the soil are strong, which can reduce a certain amount of field management workload. Do not choose clay for planting. Because it's not only low yield but it's high workload.

3. Planting methods

There are two ways of planting, but the most common one is to use direct seeding, because its germination period is not very long, so the way of direct seeding is relatively simple. Secondly, we can collect seeds in a certain time, and then we can sow them directly. More importantly, the yield is still very good, but here we still have to talk about the precautions for transplanting. That is, we have to wait until the Coptis seedlings have fourteen or fourteen leaves and apply new plants that have grown for two years before transplanting, otherwise the survival rate of Coptis after transplanting is not good and the yield is not ideal.

4. Planting density

Although Coptis chinensis does not need a lot of light, there must be a certain density between each plant, otherwise Coptis chinensis will not be able to expand, which means that the yield is not high, so we generally plant it according to the distance between each plant is five to twenty centimeters, and the distance between rows is twenty-five to thirty centimeters. In this way, Coptis chinensis has a certain growth space, the field will not appear depressed, and at the same time, it can reduce the occurrence of diseases.

5. Field management

Field management is the key to coptis planting, so there are many problems that need attention, such as weeding, fertilizing, pruning branches and leaves, clearing fields, etc. We generally need to remove grass several times for the most fertilizer, so Coptis chinensis needs to be weeded at least three times a year, which can reduce unnecessary nutrient and water consumption. Secondly, Coptis chinensis is mainly applied with farm rot fertilizer or organic fertilizer. Of course, it can also be replaced by phosphorus fertilizer, potassium fertilizer, cake fertilizer and calcium fertilizer. Finally, because coptis can grow continuously for several years, we need to cut off the excess branches and leaves of coptis to maintain the permeability of the field.
