Astragalus membranaceus can also be called cotton aphid, scutellaria, medicinal cotton, yellow ginseng, blood ginseng, human rank, etc. It is mainly produced in Inner Mongolia, Shanxi, Gansu, Heilongjiang and other places. It is a very rare traditional Chinese medicine material commonly used in China. It has enhanced immunity, liver protection, anti-aging, anti-stress and a wide range of antibacterial effects, and its commercial value is very high.
1 Analysis of related techniques of Astragalus planting
1.1 Choosing the right land for planting
Astragalus membranaceus grows in some dry, drought-tolerant areas, and the root system is very developed. According to the growth characteristics of Astragalus membranaceus, the soil depth is relatively thick, and there is a small amount of alkaline sandy soil for planting. At the same time, it is also necessary to ensure convenient drainage and sufficient light. Astragalus is most suitable for survival in soils with a certain gentle slope. Most of the wild scutellaria grows in sloped soil.
Astragalus should be based on gramineology when it is first planted and cultivated. In the spring cultivation, soil reversal should be carried out, then the soil should be excavated deep with modern mechanical equipment, and the soil slope should be guaranteed to a certain height. Within the range of 25cm to 42cm. In the growth stage of Astragalus membranaceus, scientific fertilization can be carried out according to its growth condition. It is best to use organic fertilizer reasonably according to the guidance of relevant experts. Generally, the fee range per acre can be about 3400-4700kg, and it is best to apply a small amount of compound fertilizer. The fertilizer for each element of nitrogen and potassium is controlled at about 27 kg. After using the functional fertilizer, the fertilizer should be buried under the soil next to it, and then flattened by other agricultural tools.
1.2 Analysis of related seeds of Astragalus
The outer skin of Astragalus membranaceus seeds is relatively hard, and the time of germination after planting will be slower. Therefore, seeds must be selected for seeding before planting. Seeds that have not yet appeared are germinated and grow faster, and the life rate is also very high. For seeds, they can be germinated by physical and chemical methods. The detailed method program usually contains two kinds, as follows:
(1) Boiling water germination method: first soak the seeds with water for 3 to 5 minutes, then put them into boiling boiling water continuously, and add a small amount of cold water during the stirring process until the boiling water temperature rises to 41 degrees and then stop stirring. Soak the seeds for 2.2 to 4.3 hours, pick up the seeds whose shape has changed and put them in the relevant container. Then pick the seeds with smaller shape changes and continue to put them in boiling water until they change shape. Take it out and prepare for the next sowing.
(2) Mechanical damage method: Repeat the crushing using a relatively hard round stone device, crush the hard outer skin of the jaundice, and let it leak out of the gray-brown skin and stop rolling, then put the seeds into the water again. Soak in the shape and let the shape swell.
1.3 Growth Management in Huanghua Field
Astragalus needs to absorb a lot of water during its early growth and development. Therefore, timely irrigation should be carried out to ensure sufficient water, which is conducive to the consistent growth of seedlings. It should be noted that when irrigation is carried out, it is necessary to control the amount of water. It must not be too large or too small. It is necessary to use water scientifically and reasonably.
2 Prevention and control of related diseases and insects of Astragalus
2.1 Yellow Locust Control
The damage caused by Astragalus membranaceus in the middle stage of growth is the biggest. If scientific control is not carried out, the yield will be greatly reduced. Control measures: Spray with about 1200-1600 times of oxygen-related dimethoate emulsifiable concentrate Prevention and treatment.
2.2 Astragalus seed peak hazard
At the end of the growth of Astragalus membranaceus, many worms will drill into the fruit for foraging, leaving only the hard skin on the outside. This period is the most dangerous; control measures: Mixing oxime can be mixed in the early stage of planting to reduce the damage of pests and diseases; When the damage of the relevant peaks of Astragalus membranaceus is serious, spray control with 1500 times liquid of 43% dimethoate.
2.3 Astragalus related powdery mildew pests and diseases
Many yellow sassafras leaves fall quickly and yellow, and the damage to the leaves of Astragalus membranaceus is the most serious. Powdery mildew is also very extensive. Control measures: remove more serious residual leaves, and timely take relevant drugs for spraying; use methyl thiophanate WP 1200 times liquid Biopharmaceutical, spray control.
Organic shiitake mushroom extract powder is extracted from the organic mushroom fruiting body. In the extraction process, the solvent selected is water or organic ethanol. The active ingredient of the mushroom extract is lentinan, which enhances cellular immunity, inhibits the growth of cancer cells, and is rich in fatty acids, which effectively lowers blood sugar in the body.
