How to do field management for Codonopsis pilosula? Detailed explanation of the technical key points
Codonopsis pilosula is a perennial herbaceous plant in the Campanulaceae family and has a wide distribution range in our country. The main medicinal effects of Codonopsis pilosula include tonifying the middle and boosting qi, and resolving phlegm and relieving cough, and it is mainly used to treat problems such as persistent coughing, shortness of breath and dry mouth. Now Codonopsis pilosula also has a certain area of artificial cultivation, so how should we manage it when planting Codonopsis pilosula? Below, the editor brings you the key technical points for field management of Codonopsis pilosula. Let's take a look together!
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 respiration and nutrient absorption of the Codonopsis pilosula roots. During the seedling stage, the growth ability of Codonopsis pilosula is relatively weak, so too many weeds will rob the seedlings of growth nutrients and affect the growth of Codonopsis pilosula. 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 in seedling management, and then apply fertilizer once when the seedlings grow to about 15cm. The fertilizer is mainly decomposed farmyard manure, and attention should be paid to the amount of fertilizer, controlled at about 1200 kg/mu. Because later the stems and leaves of Codonopsis pilosula have relatively long vines, topdressing work is more troublesome. After planting, water thoroughly to set the roots, and then when the seedlings survive, reduce the amount of watering or even stop watering. Then also pay attention to doing a good job in drainage, because too much accumulated water will cause the roots of Codonopsis pilosula to rot, seriously affecting the growth of Codonopsis pilosula.
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 wind onto the supports for growth. If it is too dense, appropriately thin the branches to improve the ventilation and light penetration of Codonopsis pilosula. Then when the fruit matures and the 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, and when Codonopsis pilosula is about 30 cm, cut it off in time to promote root growth.
4. Pest and disease control
Pest and disease control work 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, because excessively high temperature and humidity are the basic prerequisite for the onset of many pests and diseases. When planting, we should pay attention to frequently observing the growth of Codonopsis pilosula and carry out inspection work in the field. If abnormal conditions are 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 technical points for field management of Codonopsis pilosula. The field management work of Codonopsis pilosula is very importantly linked to yield, quality, and so on, so everyone must pay close attention. That is all for today's introduction.
