The cultivation of Chinese medicinal materials has a certain history in my country. Due to the increasing market demand, many regions are now vigorously advocating the cultivation of this kind of medicinal materials. Looking at the current domestic market, the price of traditional Chinese medicine has gradually increased, which naturally has driven farmers' enthusiasm for planting. However, due to different environmental conditions, the types of medicinal herbs grown in each area are also different, especially in some places such as Sichuan and Guizhou. The climatic conditions here are more suitable for planting Coptis chinensis, as a very valuable medicinal material, The planting value of Huanglian is very high. However, in order to achieve high yields and higher profits of the planted Coptis chinensis, farmers must understand the basic management methods in the field. So how to proceed? What should we pay attention to during planting?
When planting Coptis chinensis, the corresponding temperature must be controlled at the initial stage. After sowing, some plastic film or straw can be used for mulching to avoid unsuitable temperature affecting the growth of Coptis chinensis seedlings. At the seedling stage, pay attention to observe the moisture in the soil, and pay attention to watering as often as possible, so as to promote the faster growth of seedlings. After the seedlings have grown to a certain leaf, you can pay attention to start thinning. The purpose of thinning is to make the Coptis chinensis grow better. At the same time, before the seedling emerges, in order to make it grow more vigorously, we must also pay attention to the establishment of a sunshade, which can well shield the sunlight, avoid too much light, and cause the growth of the seedlings to be restricted, or even wither directly .
When Coptis chinensis grows to a certain stage, the management focus at this time is to pay attention to the work of supplementing seedlings. Because some seedlings grow fast during growth, but some seedlings are relatively weak, and even diseases have occurred. Timely treatment is required, and the work of supplementing seedlings is carried out, after which the colonization can begin. In general, when transplanting seedlings, you should also pay attention to uniform seedlings, and plant some other seedlings reasonably to avoid the occurrence of seedling shortages.
After planting the seedlings, you should check the growth of the seedlings in a timely manner. If there are some unfavorable conditions, you should pay attention to the timely replacement of seedlings to ensure that the growth of the seedlings is consistent. It can be said that the growth and management of Coptis chinensis at the seedling stage is very important, and it is also directly related to the overall growth situation in the future, so as a grower, the management work at this stage must be in place to avoid the failure to cause seedlings Growth is limited, or it lays some hidden dangers for future growth.
When Coptis chinensis is in the seedling stage, it is necessary to pay attention to the work of cultivating. In its entire growth stage, it usually takes about 5 times of cultivating. Especially when the seedling is transplanted, it must be carried out about 2 times to avoid affecting its growth. Especially after the rainy season, due to the increase in moisture, agglomeration may also occur in the soil at this time. If reasonable plowing is carried out, it can be well prevented from poor soil permeability at this time. It is easy to damage the root of Coptis chinensis, and it can also improve the permeability, which is beneficial to the growth of Coptis chinensis. When there are more weeds in the soil, we must also pay attention to quickly remove these weeds in time, because some weeds grow in the soil, it is easy to affect the growth of Coptis chinensis, and will compete with Huanglian for nutrients, Not conducive to the growth of Coptis chinensis.
Conversely, if weeds are not removed in a timely manner at this stage, it will result in the consumption of some nutrients, which is extremely detrimental to the growth of Coptis chinensis. When Coptis chinensis enters the stage of seedling growth, it is also important to apply topdressing reasonably. Usually, when initial topdressing, it is mainly based on farm manure, and it is also necessary to control the concentration of water and fertilizer. It is best to use it Some fertilizers with relatively low concentration may prevent too much fertilizer and cause root burning.
When the seedlings are transplanted, you can use the farm manure once. When entering the mid-term growth period, you can use a nitrogen fertilizer for additional use. At this stage, the use of fertilizers should be combined with the growth situation. If it is not good, or if it is not strong enough, fertilization can be carried out a small number of times. Since Coptis chinensis is growing, the demand for fertilizers is relatively large, so it must be noted that reasonable fertilization at each stage is necessary to meet the basic growth needs of Coptis chinensis.
During the growth of Coptis chinensis, it does not need too much sunlight. In order to make it grow better, it is necessary to pay attention to building a sunshade, which is a key point of management. The purpose of building a sunshade is to better adjust the overall light intensity, especially when the Coptis chinensis is in its initial growth, its demand for sunlight is not great, so it is necessary to carry out sunshade treatment in time and check whether the growth of Coptis chinensis is in time. normal.
