A Detailed Explanation of the Latest Field Management Techniques and Key Points for Codonopsis pilosula
Codonopsis pilosula is a perennial herbaceous plant in the Campanulaceae family, with a wide distribution range in China. Its main medicinal effects include tonifying the middle and boosting qi, and dispelling phlegm and relieving cough, and it is mainly used to treat problems such as persistent coughing and shortness of breath with dry mouth. Now Codonopsis pilosula also has a certain area of artificial cultivation, so how should we manage it when growing Codonopsis pilosula? Below, the editor brings you the key points of field management techniques for Codonopsis pilosula. Let's take a look!
1. Intertillage and weeding
After the Codonopsis pilosula seedlings emerge, intertillage and weeding work should begin, and management should be strengthened. The quality of intertillage and weeding work has a very important impact on the growth of Codonopsis pilosula. This is because intertillage can improve the properties of the soil, enhance soil quality, and provide high-quality conditions for the root respiration and nutrient absorption of Codonopsis pilosula. During the seedling stage, the growth capacity of Codonopsis pilosula is relatively weak, so excessive weeds will snatch away the growth nutrients of the Codonopsis pilosula seedlings and affect their growth. Therefore, everyone must not neglect intertillage and weeding when carrying out management.
2. Water and fertilizer management
After the seedlings are successfully established, do a good job of seedling management, and then apply fertilizer once when the seedlings grow to about 15cm. The fertilizer should mainly be decomposed farmyard manure, and attention should be paid to the fertilizer amount, controlling it at about 1200 kg/mu. Because the stems and leaves of Codonopsis pilosula are relatively long in the later stage, topdressing work is rather troublesome. After planting, water thoroughly to settle the roots, and then after the seedlings survive, reduce the amount of watering or even stop watering. Also pay attention to drainage work, because excessive water accumulation will cause the roots of Codonopsis pilosula to rot, seriously affecting its growth.
3. Trellising and seed collection
Codonopsis pilosula is a vining crop, so during planting we should set up trellises in time according to the actual situation. Generally, when the Codonopsis pilosula seedlings grow to about 30 cm, insert supports between the seedling rows. Encourage Codonopsis pilosula to twine onto the supports for growth. If it is too dense, appropriate branch thinning can be done to improve the air and light permeability of Codonopsis pilosula. Then, when the fruit matures and its color turns white, cut off the stems and vines to remove the seeds. Then select high-quality seeds and place them in a dry and cool place. If seeds do not need to be retained, then trellising is not necessary; cut it off in time when Codonopsis pilosula is about 30 cm to promote root growth.
4. Pest and disease control
Pest and disease control for Codonopsis pilosula is the most important point among all management tasks, and its common pests and diseases include rust, root rot, and aphids. We should strengthen management and control the temperature and humidity in the field well; excessively high temperature and humidity are the basic prerequisites for the onset of many pests and diseases. During planting, we should pay attention to frequently observing the growth of Codonopsis pilosula and carry out inspection work in the field. If any abnormal situation is found, be sure to promptly check the specific cause, and do not handle it blindly, so as to avoid worsening the condition.
The above is a brief introduction to the key points of field management techniques for Codonopsis pilosula. The field management work of Codonopsis pilosula is very importantly related to yield, quality, and so on, so everyone must pay close attention. That is all for today's introduction.
