The latest key points of field management of Ligusticum chuanxiong

Ligusticum chuanxiong is a perennial herb of Umbelliferae, which has strong root growth ability and strong fragrance. There is a wide range of planting areas in China, and management is very important when planting Ligusticum chuanxiong. A reasonable field management technique is the key to ensure the yield and quality of Ligusticum chuanxiong. So how to manage planting Ligusticum chuanxiong? The following editor brings you the key points of field management of Ligusticum chuanxiong. Let's have a look!

1. Ploughing and weeding

Intermediate ploughing and weeding is very important to the growth of Ligusticum chuanxiong. Then after about 3 weeks, we should pay attention to the depth, not too deep, so as to prevent damage to the root of Ligusticum chuanxiong and affect the growth. The third intertillage should be carried out during the peak period of underground rhizome growth. Ligusticum chuanxiong should be ploughed at least 4 times in the planting process, and the last one should be carried out in the spring of the following year. Before ploughing, attention should be paid to cleaning up the old stems and leaves in the field, and then cultivating soil in the roots after completion, so as to improve the cold resistance of the roots and promote them to survive the winter.

2. The seedlings are fixed

The purpose of inter-seedling is to prevent the strong seedlings from crowding each other, preventing each other from grabbing the nutrient water needed for growth and affecting the normal growth. Generally, when the seedlings grow to about 12 cm from March to April every year, we should try our best to fix the seedlings, and pay attention to the growth of the seedlings. To choose strong, disease-and insect-free seedlings, remove weak growth, poor growth of seedlings. Then control the planting density and do a good job of fixing seedlings. Do not be too dense, otherwise the work of fixing seedlings will lose its effect. The seedlings in each litter are kept at about 10.

3. Rational fertilization

In the first two years of planting Ligusticum chuanxiong, the growth of its aboveground part will be more exuberant, and the formation rate of nutrient area will be relatively fast. Only by producing a large amount of dry matter can adequate vegetative growth of the rhizome be ensured. Therefore, when we plant Ligusticum chuanxiong, we should pay attention to fertilizing. In the first two months of planting, topdressing should be carried out at least 3 times, and each topdressing can be carried out with ploughing and weeding. The fertilizer is mainly rotten farm manure, which is applied to the site of the plant hole. Generally speaking, it has to be done before Frosts Descent in order to ensure the effect.

4. Timely harvest

The harvest season of Ligusticum chuanxiong is generally the most suitable for harvesting within one week of Lesser Fullness of Grain in the second year of planting. The harvest time should not be too early and too late, if it is too early, the underground rhizome is not yet fully mature, which will have a certain impact on the yield. However, if the harvest is too late, the rhizome is too mature and easily rotten underground, resulting in a decline in yield and affecting the economic benefits of planting. When harvesting, you should pay attention to choose a sunny day, not in a rainy day, dig up the whole plant, then remove the stems and leaves, remove the soil, and put it on the market after a little sun for 2-3 hours.

The above is a brief introduction of the main points of field management of Ligusticum chuanxiong, and the pest control and management of Ligusticum chuanxiong is also very important. The common diseases and insect pests are root rot, stem node moth and so on, which will harm the plant growth of Ligusticum chuanxiong in varying degrees.
