Field management techniques of motherwort

Motherwort is a traditional Chinese medicine in China, which has been an important medicine for gynecological diseases since ancient times. in modern times, its efficacy has been further developed. it is one of the important raw materials of many kinds of proprietary Chinese medicine. it is in great market demand and is cultivated in many areas. Only by doing a good job in field management can we achieve high yield and high yield. let's take a look at the field management techniques of motherwort with Xiaobian.

1. Replenish seedlings with intermediate seedlings

The management of the seedling stage is related to the growth status of the plant. when the seedling grows to 5 cm, it is necessary to start the seedlings, and the seedlings should be carried out 2-times one after another, to remove the disease and insect seedlings and weak seedlings, and to keep the strong seedlings to promote the seedlings to grow healthily and neatly. When the seedlings grow to 15-20 cm, the seedlings are fixed, the wrong plants are taken to keep the seedlings, and the distance between the plants is controlled at about 10 cm, while 2-3 strong seedlings are left in each hole of the hole sowing. After the seedlings are found to be missing and dead, the seedlings should be replenished in time.

2. Ploughing and weeding

In order to promote the growth of seedlings, timely weeding work is necessary, ploughing loose soil, increase soil permeability, can promote seedling root growth and development, and weeding should be diligent, so that there are no weeds in the field. The spring sower ploughed and weeded three times in time, usually together with the seedlings; the summer sower should carry out timely according to the growth of the plant; the autumn sower carried out the first time when the seedlings grew 3-4 true leaves, and three times of interploughing and weeding the following year, just like spring sowing. When ploughing, we should pay attention to the depth, not too deep, so as not to hurt the root system of the plant. It is best to cultivate the soil and protect the root in order to avoid plant lodging.

3. Watering and topdressing

Watering once before weeding each time, this moist soil is beneficial to weeding and can also increase the permeability of the soil. After each ploughing and weeding, it is necessary to top fertilize once, mainly nitrogen fertilizer, urea, ammonium sulfate and cake fertilizer. Pay attention to watering after fertilization and dilute the fertilizer concentration so as not to burn the seedlings with too high fertilizer concentration. Especially when applying cake fertilizer, it should be broken and diluted with water, and drainage measures should be taken in the rainy season to avoid stagnant water and rot the roots.

4. Pest control

The diseases of motherwort include powdery mildew, Sclerotinia sclerotiorum and mosaic disease, insect pests include aphids in spring and autumn, and small land tigers harm roots. During the onset of powdery mildew, powdery mildew was sprayed and Sclerotinia sclerotiorum could be sprayed with Rhizoctonia solani, Bordeaux solution or Sclerotinia sclerotiorum. Aphids can be controlled with assessment agents, and small land tigers can be killed artificially or trapped by heap grass.
