High-yield cultivation techniques of motherwort

Motherwort, don't Mingkun grass, hemp and so on. It is an annual herb of Labiatae. It has the effect of promoting blood circulation and regulating menstruation, diuresis and detumescence. Clinical treatment of irregular menstruation, dysmenorrhea, amenorrhea, lochia, acute glomerulonephritis edema and other diseases. The seed medicine is called Qiuweizi, which has the effects of promoting blood circulation and regulating menstruation, benefiting yin and eyesight. The main treatment of irregular menstruation, postpartum blood stasis pain, blood stagnation eye pain and so on.

Morphological characteristics 1. Annual or biennial herbs. Stem erect, 60-120cm tall, obtusely quadrangular, minutely sulcate, with inverted strigose hairs, much branched. Leaves opposite; petiole slender, 2-3cm long, upper stalk shorter; lower leaf outline of stem ovate, base broadly cuneate slightly decurrent, palmately 3-lobed, lobes oblong-rhombic to ovoid, usually 2.5-6cm long, 1.5-4cm wide, lobes redivided, strigose above, sparsely pilose and glandular dots below; middle leaves of stem rhombic, smaller, usually divided into 3 or occasionally more oblong linear lobes Bracts subsessile, linear or linear-lanceolate, entire or sparsely dentate. Verticillate inflorescences axillary, with 8-5 flowers, mostly far away to form long spikes; bracteoles spiny, shorter than calyx tube, ca. 5mm long; without pedicel; calyx tubular-campanulate, 6-8mm long, outside Adnate puberulent, upper inner surface pilose, apex 5-toothed, teeth broadly triangular, tip prickly. Corolla pink to purplish red, 1-1.2cm long, Corolla tube ca. 6mm, outer pilose, limb 2-lipped, lower lip ca. as long as upper lip, 3-lobed, middle lobe obcordate, apex emarginate; stamens 4-strong, filaments sparsely scalelike; style slightly beyond stamens, apex 2-lobed; disk flat. Nutlets oblong-trigonous, long 2.5mm, light brown, smooth. The florescence is from June to September and the fruiting period is from September to October.

The white flower variety of this species, also known as white flower motherwort, is used as medicine as the orthodox species. The main difference lies in the white Corolla of this variety.

2. The morphological characteristics of this species in Labiatae are very similar to those of Leonurus. The main differences are as follows: the leaves of this species are divided into linear lobules, usually 1-3mm wide, the bracts on the inflorescence are obviously 3-parted, and the lobules are linear; the Corolla is larger, about 1.8cm long, outer villous, and the lower lip is 1 × 4 shorter than the upper lip; the outer part of the calyx is densely sparsely pilose especially in the middle. The flowering period is from July to September and the fruiting period is from September to October. Born on stony and sandy grasslands and pine forests, up to 1500m above sea level.

The white flower form of this species is also used in medicine, and the difference between it and the orthodox species is that the Corolla is white.

First, growth habits: motherwort likes warm and humid climate. Adaptability is relatively strong. The requirement of soil is not strict, but it is better to use deep, loose and fertile sandy loam or loam.

Second, soil preparation and fertilization: select fields with high terrain, good drainage and deep soil layer, and work carefully in spirit. Combined with soil preparation, apply sufficient basic fertilizer: 3000 kg of soil miscellaneous fertilizer, 10 kg of urea and 50 kg of phosphorus and potassium fertilizer per mu. Then make beds and wait for sowing.

Third, sow seeds. Motherwort propagates with seeds, and the sowing time is spring sowing and summer sowing. Spring sowing before and after the Qingming Festival, summer sowing around Grain in Beard. When sowing, sow motherwort seeds into the right border surface. Or first on the finished surface of the border, open it into a shallow ditch, and then spread the seeds evenly into the ditch, cover the soil, water and preserve soil moisture, in order to facilitate the emergence of seedlings. The sowing rate is 2 kg per mu.

Fourth, after the field management of motherwort seedlings, attention should be paid to ploughing and weeding. Water in time in dry weather, pay attention to drainage in cloudy and rainy weather. Topdressing once before and after closure: 10 kg of urea and 5 kg of potassium dihydrogen phosphate per mu.

Fifth, the main diseases of motherwort are powdery mildew and rust, which can be controlled by strychnine at the initial stage of the disease. Pests include aphids and red spiders, which can be controlled by aldicarb and propargite. Underground pests are trapped and killed with octane scales and poison bait.

6. harvesting and processing motherwort is generally close to maturity in the lower part of the seed after autumn, while the upper part is still harvested when it is in full bloom. When harvested, the plant is planted and cut off, dried in the sun and then sold as medicine. The yield is 500 kilograms per mu.
