Astragalus membranaceus, alias gold root, Camellia root, and Astragalus tea, is a plant of the family Labiatae. Its roots are used for medicinal purposes. The main components are astragalus, baicalein, wogonin and astragaloside, which have heat, purging fire and detoxification. It has the effects of warming, pneumonia, hemoptysis, jaundice, hepatitis, dysentery, redness, and fetal dysfunction. It is one of the commonly used Chinese herbal medicines in Zhongyuan. The following is the details of the artificial planting technology of Astragalus membranaceus for your reference.
I. Biological ecological characteristics
Astragalus is a perennial herb with a plant height of 20-50 cm. The main root is conical, 10 to 30era long and 1 to 2era in diameter. The outer skin is yellowish brown and yellow inside. Stems clumpy, base undulate, slightly ascending or erect, sessately sessately sessately sessately sessately sessately sessately lanceolately lanceolately lanceolately lanceolately lanceolately lanceolately lanceolate lanceolate Racemes terminal, flowers arranged to one side densely arranged; calyx tube-shaped outside densely densely villous; corolla purple, 2-lipped; stamens 4, 2 strong; 1 pistil, ovary 4 deeply divided, ovate Orange succulent disk. 4 small nuts, oval, black, with a tumor on the surface, about 1mm in diameter, surrounded by the sputum. Flowering period from June to September, fruiting period from July to October.
Huang Yu enjoys a mild climate and is resistant to cold and drought. The original wild is on the hillside, the mantle, and the forest edge is sunny and dry. The soil requirements are not strict, the drainage is good, the fertile sandy loam is the best, and it can be planted in the hills and thin land.
Second, breeding methods
Breeding with seeds and roots.
1. Land selection and land preparation: Choose sunny, well-drained, deep soil, fertile sandy loam is appropriate, avoid continuous cropping. Each acre is smashed with 3000kg of farmyard manure, 20kg of superphosphate, and 25~30era.耙 Thin and flat, for a width of 1.2m, the length is not limited.
2. Seed propagation: 1 seed collection. The selected robust and robust plants are collected, the period of the yellow sassafras is long, the seed maturity period is inconsistent, and it is easy to fall off. Therefore, after the ripening and mouth mining, the seeds are dried after drying, the seeds are laid, and the impurities are reserved. 2 soaking seeds. Before sowing, soak the seeds with warm water of 40 ~ 50 °C for 5 ~ 6h, remove them and dry them to sow. 3 sowing. It is divided into spring and autumn. Spring sowing is carried out from mid-April to early May, and autumn sowing is from mid-August to late September. Ditch according to the row spacing of 30~40cm, the ditch depth is 0.5~lcm, the seeds are evenly spread in the ditch, covered with fine soil, watered after slightly repressing, keeping the soil moist, in order to ensure the soil is moist, after planting, the wheat straw can be covered and Straw, in order to produce seedlings, at a temperature of 15 ~ 18 ~ C, 10 to 15 days after sowing. The germination rate of Astragalus membranaceus seeds is about 60%, and the seeding amount of acre is 1~1.5kg. The seeding of Astragalus membranaceus is the key. Due to the poor ability of the seed to make a small top soil, the planting should be shallow and the soil should be thin. If the seeding is too deep, the soil will not be able to emerge.
3. Root-to-root reproduction: Before the spring scutellaria has not sprouted new shoots, the roots are dug out, the main roots are cut for medicinal use, and then the roots of the mother plants are cut into several pieces according to the size of the root-stem block, each of which has 2 to 3 buds. Row spacing 15cmx3Oem burrowing planting, covering soil compaction, watering, seedlings can grow in about 10 days. This method can shorten the growth cycle, but it has more roots than the live broadcast.
Third, field management
1 seedling: After the seedlings are out, the dense and thin seedlings are dropped in 2 times, and the seedlings are fixed according to the plant spacing of 10-15 cm.
2. Cultivating and weeding: After the seedlings are unearthed, weeding and weeding in time, combined with loose soil to properly cultivate the soil around the seedlings, 2 to 3 times a year, no weeds, which is conducive to the normal growth of the plants.
3. Top dressing: When the seedling height is 10~15cm, apply a light human and human waste water to help the seedling grow and increase the yield. At the end of June and the beginning of July, 20 kg of superphosphate and 5 kg of urea were applied per mu, and the ditch was applied between the rows, and the soil was poured after covering the soil.
4. Remove the flower buds: If the seeds are not collected, cut the flower branches, reduce the consumption of nutrients, promote root growth and increase yield. In addition to planting the fields, the flowering period should be sharpened in time, and the flower buds should be cut off in the sunny day to promote the growth of the roots.
Fourth, pest control
The main pests and diseases have leaf blight, which damages the leaves and extends inward from the tip or leaf margin. It is irregular black-brown lesions and spreads rapidly, causing the leaves to die. It is heavy in the hot and rainy season. Spray with 50% carbendazim looo solution, spray once every 7 to 10 days, and spray continuously for 2 to 3 times.
V. Harvest processing
Astragalus is rooted in medicine. After planting for 2 to 3 years, harvest the roots. When the stems and leaves are yellow, the roots will be removed. The stems and leaves will be removed, the soil will be shaken, and when the sun is dried, it will hit the outer skin and then dried or dried. 150-200kg of dry goods per mu.
