How to plant motherwort seeds?

Motherwort is an annual or biennial plant of the genus Leonurus of the labial family, which is distributed all over China. It is divided into precocious motherwort and winter motherwort. It is generally propagated by seeds, planted by direct seeding, and transplanting seedlings, but the yield is low, so it is not used. Let's take a look at how motherwort seeds are planted.

Preparation for sowing motherwort

Motherwort was propagated by seeds and planted by direct seeding. Before sowing, the seeds were mixed with fire ash or fine soil fertilizer, and then mixed with human and animal feces and urine and new high-fat film to ward off underground diseases and insects, isolate virus infection, strengthen respiratory intensity and improve seed germination rate. Choose seeds that are fresh in that year and have a germination rate of more than 80%. Burrowing sowers prepare 400 grams per mu, while strip sowers prepare 500 grams per mu.

Sowing time of motherwort

Precocious motherwort can be sowed in autumn, spring or summer, and winter motherwort must be sowed in autumn. It is suitable for spring sowing from Rain Water to sting (from late February to early March). In the north, summer sowing is used to make use of summer leisure land, and the yield is not high after Grain in Beard harvested wheat. Autumn sowing is mostly adopted in low temperature areas, and the soil is the best when the soil is moist from the Autumn Equinox to Cold Dew (from late September to early October). The choice of sowing date in autumn is directly related to the output and quality of products. It is premature and vulnerable to aphids. Too late, affected by low temperature and dry soil, it could not germinate that year, but the Spring Equinox could not germinate until Qingming Festival the next year, and the germination was irregular and irregular, and most of them could not sprout and blossom.

Sowing method of motherwort

Motherwort sowing is divided into strip sowing, hole sowing and sowing. Strip sowing is mostly used in plain areas, hole sowing is often used in sloping land, and sowing management is not convenient and not adopted. Before sowing, mix the seeds with fire ash or fine soil fertilizer, and then mix the seeds with human and animal manure and urine, and the humidity can be dispersed. Generally, 250,300kg of fire ash or soil fertilizer and 35,40kg of human and animal manure are used per mu. Strip sowing opens a horizontal ditch in the border, the distance between the center of the ditch is about 25 cm, the sowing area is about 10 cm, and the depth is 4-7 cm. The bottom of the ditch should be flat. Before sowing, 2500-3000 kg of human and animal feces are applied in the ditch, and then the seed ash is scattered evenly without covering the soil. The acupoint is about 25 cm apart from each other. The diameter of the acupoint is about 10 cm and the depth is 3-7 cm. The bottom of the acupoint should be flat. After applying 1000-1200 kg of human and animal dung and urine in the acupoint, it is not necessary to spread seed ash evenly.
