The latest Dangshen field management techniques tutorial points

Codonopsis pilosula is a perennial herb of Campanulaceae, which has a wide range of distribution in China. The main effects of Codonopsis pilosula are Buzhong Yiqi, expectorant and cough, which are mainly used in the treatment of cough, shortness of breath, dry mouth and so on. Now Codonopsis pilosula also has a certain artificial planting area, so how should we manage it when planting Codonopsis pilosula? The following editor brings you the technical points of the field management of Codonopsis pilosula. Let's have a look!

1. Ploughing and weeding

After the seedlings of Codonopsis pilosula are unearthed, it is necessary to carry out intermediate ploughing and weeding and strengthen management. The effect of weeding in intertillage on the growth of Codonopsis pilosula is very important. Because mid-tillage can improve the properties of the soil, strengthen the quality of the soil, and provide high-quality conditions for the respiration and nutrient absorption of Codonopsis pilosula roots. In the seedling stage, the growth ability of Codonopsis pilosula is relatively weak, so too many weeds will rob the growth nutrition of Codonopsis pilosula seedlings and affect the growth of Codonopsis pilosula. Therefore, when carrying out management, we must not ignore ploughing and weeding.

2. Water and fertilizer management

After the seedlings are successfully planted, do a good job in seedling management, and then top fertilize once when the seedlings reach about 15cm. The main fertilizer is rotten farm manure, in which attention should be paid to the amount of fertilizer, which should be controlled at about 1200 kg / mu. Because in the later stage, because the stems and leaves of Codonopsis pilosula are longer, the work of topdressing is more troublesome. After planting, it is necessary to irrigate enough water for fixed roots, and then reduce the amount of water or even no watering when the seedlings survive. Then we should also pay attention to the drainage work, too much water will lead to Codonopsis retting root rot, seriously affecting the growth of Codonopsis pilosula.

3. Set up a frame to collect seeds

Codonopsis pilosula is a trailing crop, so we should set up a fight in time according to the actual situation. Generally, when the seedlings of Codonopsis pilosula grow to about 30 cm, the stents are inserted between the rows of the seedlings. Promote Codonopsis pilosula winding to the bracket for growth, if it is too dense, it can properly do branch thinning work to improve the permeability of Codonopsis pilosula. Then, when the fruit is ripe and the color changes to white, cut off the vines and remove the seeds. Then pick out high-quality seeds and put them in a dry and cool place. If there is no need to leave seed, then there is no need to build a frame, when Codonopsis pilosula is about 30 cm, it can be cut off in time to promote the growth of the root.

4. Pest control

The pest control of Codonopsis pilosula is the most important point in all the management work, and the common diseases and insect pests are rust, root rot, aphids and so on. We should strengthen management and control the temperature and humidity in the field. Too high temperature and humidity is the basic prerequisite for the incidence of many diseases and insect pests. When planting, we should always observe the growth of Codonopsis pilosula and inspect the fields. If there is an abnormal situation, we must check the specific reasons in time, do not deal with it blindly, and avoid aggravating the disease.

The above is a brief introduction of the key technical points of the field management of Codonopsis pilosula. The field management of Codonopsis pilosula has a very important relationship with output and quality, so we must pay more attention to it. That's all for today's introduction.
