A Detailed Guide to the Latest Field Management Techniques for Motherwort
Motherwort is a traditional Chinese medicinal herb. Since ancient times it has been an important medicine for treating gynecological diseases, and in modern times its effects have been further developed. It is one of the important raw materials for many Chinese patent medicines, with huge market demand, and it is cultivated in many regions. Only by doing a good job in field management can high and quality yields be obtained. Now, let's take a look at the field management techniques for motherwort with the editor.
1. Thinning and Replanting
Management during the seedling stage affects the growth condition of the plants. When the seedlings grow to 5 cm, thinning should begin. Thinning should be carried out successively 2 times, removing diseased and pest-damaged seedlings and weak seedlings, and keeping strong seedlings, so as to promote robust and uniform seedling growth. When the seedlings grow to 15-20 cm, final thinning should be carried out. For drill sowing, keep seedlings in staggered positions, controlling the plant spacing at about 10 cm, while for hole sowing, keep 2-3 strong seedlings per hole. After thinning and final thinning, if missing or dead seedlings are found, replant them in time.
2. Cultivation and Weeding
In order to promote robust seedling growth, timely cultivation and weeding work is necessary. Cultivation loosens the soil and increases soil permeability, which can promote the development of the seedling root system, while weeding should be done frequently so that there are no weeds in the field. For spring sowing, cultivation and weeding should be carried out 3 times in a timely manner, usually together with thinning; for summer sowing, it should be carried out at the appropriate time according to the growth condition of the plants; for autumn sowing, the first cultivation and weeding should be carried out when the seedlings grow 3-4 true leaves, and in the following year three more cultivation and weeding operations should be carried out, the same as for spring sowing. During cultivation, pay attention to the depth, which should not be too deep, so as not to damage the plant roots. It is best to earth up around the roots during the last cultivation to prevent the plants from lodging.
3. Watering and Topdressing
Water once before each cultivation and weeding. This moistens the soil, facilitates weeding, and can also increase soil permeability. After each cultivation and weeding, apply topdressing once. Fertilization should mainly be nitrogen fertilizer; urea, ammonium sulfate, and cake fertilizer are all acceptable. After fertilizing, pay attention to watering to dilute the fertilizer concentration, so as not to burn the seedlings due to excessively high fertilizer concentration. Especially when applying cake fertilizer as topdressing, it should be crushed, diluted with water, and then applied. During the rainy season, drainage measures should be well carried out to avoid root rot caused by water accumulation.
4. Pest and Disease Control
The diseases of motherwort include the harm caused by powdery mildew, sclerotinia rot, and mosaic disease. Among pests, aphids cause harm in spring and autumn, and cutworms harm the root system. When powdery mildew occurs, spray triadimefon for control; for sclerotinia rot, spray Ruikumai, Bordeaux mixture, or dimethachlon for control. Aphids can be controlled with chemical preparations, and cutworms can be controlled by manual capture or by piling grass to trap and kill them.
