The latest course of field management techniques and methods of motherwort

Motherwort is a traditional Chinese medicinal material in China. Since ancient times, it has been an important medicine for gynecological diseases. In modern times, its efficacy has been further developed. It is one of the important raw materials for various Chinese patent medicines. The market demand is great. Many areas have been cultivated. Only by doing a good job in field management can we obtain high yield and excellent yield. Let's take a look at the field management technology of motherwort together with Xiaobian.

1. Thinning and replenishing seedlings

The management of seedling stage is related to the growth status of plants. When seedlings grow to 5 cm, they should start thinning seedlings. Thinning seedlings should be carried out 2-times in succession. Diseases and diseases should be removed. Strong seedlings should be retained to promote strong and tidy growth of seedlings. When the seedlings grow to 15-20 cm, the seedlings shall be fixed, the wrong plants shall be taken for drilling, the plant spacing shall be controlled at about 10 cm, and 2-3 seedlings shall be reserved for each hole for hole sowing. After thinning and fixing seedlings, the phenomenon of lack of seedlings and dead seedlings shall be found, and the seedlings shall be supplemented in time.

2. Intertillage and weeding

In order to promote seedling growth and health, timely intertillage weeding work is necessary, intertillage loose soil, increase soil permeability, can promote seedling root growth and development, and weeding should be frequent, so that there is no grass in the field. Spring sower intertillage weeding should be carried out 3 times in time, usually together with thinning seedlings; summer sower should be carried out in due time according to the growth of plants; autumn sower should carry out the first time when seedlings grow 3-4 true leaves, and carry out three intertillage weeding in the following year, just like spring sowing. Intertillage should pay attention to depth, not too deep, so as not to damage the roots of the plant, it is best to intertill once in order to avoid lodging of the plant, to cultivate soil and protect the roots.

3. Watering and topdressing

Watering once before each intertillage weeding, which moistens the soil, is conducive to weeding, but also can increase the permeability of the soil, after each intertillage weeding, topdressing once, mainly nitrogen fertilizer, urea, ammonium sulfate, cake fertilizer can be, after fertilization, pay attention to watering, dilute fertilizer concentration, lest fertilizer concentration is too high to burn seedlings. Especially when applying cake fertilizer, it is necessary to break it up and dilute it with water. In the rainy season, drainage measures should be taken to avoid standing water and rotten roots.

4. Pest control

Motherwort's diseases include powdery mildew, sclerotia and mosaic disease, aphids in spring and autumn, and black cutworm damaging roots. When powdery mildew occurs, triadimefon can be sprayed to control it; sclerotium can be sprayed with ruicumei, bordeaux mixture or sclerotium. Aphids can be evaluated to learn the preparation control, small cutworm can be artificially killed or trapped heap grass.
