Atractylodes seeding technology to master
Atractylodes is one of the commonly used varieties of Chinese herbal medicines. There are three kinds of Atractylodes: First, traditionally cultivated Atractylodes macrocephala, small size, low yield, commonly known as Atractylodes macrocephala; Second, the newly developed Atractylodes macrocephala in recent years, large head, high yield, commonly known as modified Atractylodes; three is between Atractylodes macrocephala The breeds between the improved Atractylodes macrocephala and the growers are collectively referred to as bisexual Atractylodes macrocephala and their yields are between Atractylodes macrocephala and Atractylodes macrocephala. Generally, Atractylodes can produce about 600 kilograms of fresh produce per acre, bisexual Atractylodes is about 900 kilograms, and improved Atractylodes yields about 1,500 kilograms per mu. At present, Atractylodes is a development trend. To achieve high yields of Atractylodes, it is necessary to make efforts in variety, seeding, and management.
1. Pick high quality pure seeds. After drying the seeds before sowing, use 4-5 kg ​​per mu. Each 5 kg Atractylodes seeds can be coated with 10 ml bright shield + 10 grams Rui Sheng 150 grams of water, and then dry in the shade for use.
2. Site preparation. Atractylodes is an annual medicine, usually before and after the convulsions, pay attention to the preparation of the base fertilizer, apply 2000-2500 kilograms of decomposed organic fertilizer or 4-6 bags of organic fertilizer, 50 kg of potassium sulfate compound fertilizer, 1 kg of rich state per acre. The basic application of boron fertilizer, 150 grams of yttrium granules zinc spin, flat. It is more suitable to grow small ridges with a row spacing of 12-18 cm. This will not only benefit the management of crops, but also play a role in ventilation and light transmission. Immediately after planting, use 100 ml of Jinduer to evenly spray 30 kg of water to control the occurrence of weeds at the seedling stage.
3. Field management. Before Atractylodes macrocephala did not produce Qimiao, we must always keep the ground moist and we must carry out shallow rowing in order to facilitate the seedlings to reach Miao Qi Miao Zhuang, and lay a solid foundation for high yield. When Atractylodes grows to 4 leaves and 1 heart, use 10 ml of roxithromycin + 3 g of Bi-Yuan or 30 g of rendolph + 15 ml of chlorophyll or 3 g of Bi-Cu + 25 g of copper hydroxide for 15 kg of water. Spray, interval 5-7 days, continuous spraying 2-3 times is appropriate. Can also be used interchangeably to avoid drug resistance. In late July to early August, it is possible to combine irrigated land with 1.5-2 kg of spray per acre, 500 ml of sea chlorophyll + 200 ml of fruit and vegetable calcium carbonate, or 12 g of bauxite, and 2 g of soil remediation. - 3 bottles + Calcium calcium 20 kilograms, depending on the circumstances for the increase in the amount of medication for heavy parcels of land.
4. Pest control. Diseases of Atractylodes macrocephala after coating are generally dominated by diseases such as basal rot, blight, root rot, and iron leaf disease during seedling stage. 3 g of Bacchusin + 25 g of copper hydroxide or 15 ml of chlorophyll + 40 g of phosphorus and potassium power + 10 g of Xiu Miao (metalaxyl + hymexazol) can be used to irrigate 15 kg of water. Root rot can be used 15 ml of sea chlorophyll + 10 g of ethyl iodide +1 g of Bi-protector or 30 g of basal multi-dosage +15 ml of coluric ammonia +3 g of Bacau to 15 kg of water, to irrigate the roots, successively 2-3 Times, interval 5-7 days, can also be used interchangeably. Iron leaf disease sprays 15 kilograms of water with 25 grams of Cobo (Manzon Manganese + Bordeaux) + 15 ml of chlorophyll or 20 g of chlorothalonil + 3 g of Bica.
Dexamethasone injection belongs to adrenocortical hormone drugs, which has the effects of anti-inflammatory, anti allergic and anti shock. Clinically, it is mainly used for allergic and autoimmune diseases. Such as rheumatoid arthritis, bronchial asthma, dermatitis and other allergic diseases. It is mainly used for allergic and autoimmune inflammatory diseases, such as connective tissue disease, rheumatoid arthritis, severe bronchial asthma, dermatitis and other allergic diseases, ulcerative colitis, acute leukemia, malignant lymphoma and so on.
pharmacological action
Dexamethasone, also known as dexamethasone, methylprednisolone and desamethasone, is a glucocorticoid hormone. Its derivatives include hydrocortisone and prednisone. Its pharmacological effects are mainly anti-inflammatory, anti-toxic, anti allergic and anti rheumatism. It is widely used in clinic. It is easily absorbed from the digestive tract. Its plasma T1 / 2 is 190 minutes and tissue T1 / 2 is 3 days. After intramuscular injection of dexamethasone sodium phosphate or dexamethasone acetate, the blood concentration peak is reached at 1 hour and 8 hours respectively. The plasma protein binding rate of this product is lower than that of other corticosteroids. The anti-inflammatory activity of 0.75mg is equivalent to 5mg prednisolone. Adrenocorticosteroid drugs * are more effective than prednisone in anti inflammation, anti allergy and antivenom. The effects of water and sodium retention and promoting potassium excretion are very mild, but intramuscular injection or intravenous drip can inhibit pituitary adrenal gland.
1. Anti inflammatory effect: it can reduce and prevent the reaction of tissue to inflammation, so as to reduce the performance of inflammation. Hormones inhibit the aggregation of inflammatory cells, including macrophages and leukocytes, phagocytosis, the release of lysosomal enzymes and the synthesis and release of inflammatory chemical mediators.
2. Immunosuppressive effect: it includes preventing or inhibiting cell-mediated immune response, delayed allergic reaction, reducing the number of T lymphocytes, monocytes and eosinophils, reducing the binding ability between immunoglobulin and cell surface receptors, and inhibiting the synthesis and release of interleukin, so as to reduce the transformation of T lymphocytes into lymphoblasts, And reduce the expansion of primary immune response. It can reduce the passage of immune complex through basement membrane and reduce the concentration of complement and immunoglobulin.
The product is easily absorbed from the digestive tract. The plasma T1 / 2 is 190 minutes and the tissue T1 / 2 is 3 days. After intramuscular injection of dexamethasone sodium phosphate or dexamethasone acetate, the blood concentration reaches the peak at 1 hour and 8 hours respectively. The plasma protein binding rate of this product is lower than that of other corticosteroids. The anti-inflammatory activity of 0.75mg of this product is equivalent to 5mg prednisolone.
