Schisandra is a berry of the Schisandra chinensis (Turcz.) Baill. It is suitable for a wide range of habitats and is suitable both in the north and south. Since it is mainly produced in the northeast region, it is often called as schisandra chinensis. Lungs, nourishing kidney essence, thirst, effectiveness, medicinal value and economic value are higher. In recent years, with the expansion of its processing and application range, the amount of international trade has increased year after year, the value of products has been steadily rising, and the development prospects are very broad. In production, the seedlings of schisandra are very scarce, and it is extremely urgent to speed up the production of seedlings. Seedling propagation can be used for seeding, cuttings and layering, but seed production is the main method of seed propagation. According to my seedling practice, the seedling technology is briefly introduced as follows: I. Seed collection and seed processing Around mid-August Degree (reddening) The seeds are basically the same, the fruit pieces are rinsed with fresh water, the grains are rinsed, rinsed with 0.1-0.3% potassium permanganate solution for about one hour, rinsed with water, and dried in the room for one week. Turn it once a day, then mix it with 3 times clean sand and cover until cool and dry. Depth not more than 40cm in the pit. If there are many seeds, you can use a bamboo stick or corn stick to form a “vent hole†every 50cm in the pit. The sand should be kept at a certain humidity (it is suitable to hold it in groups and not drip), and the net sand on the cover is 20cm. The storage process is checked 2-3 times a month. If it is found that the seed has become mildly warm, it should be disinfected immediately or transferred to another location. From the sand trap to the end of March of the following year, check if there are seed cracks. If the crack starts, increase the sand moisture content and turn it up and down. If there is no crack, use a plastic arch to increase the temperature. When the seed has two-thirds of the gap, , you can start sowing. Second, the choice of nursery and pre-sowing preparation Because the Schisandra seed grain is small, seedlings are difficult, so the nursery should choose convenient, flat, well-watered, well drained, loose, fertile sandy land blocks, nursery should be frozen in the soil Before the deep-turning, in order to facilitate the loose soil, insecticidal sterilization. About half a month before sowing, in order to prevent the occurrence of seedling diseases and insect pests, combined with land preparation, 10 kg of carbofuran, 5 kg of carbendazim and 10 kg of compound fertilizer were applied per acre, and the soil blocks were smashed to remove all the weed stones. Fuping plots. III. Seeding After the above preparations are completed, you can start sowing, usually using a high bed nursery, bed height 20cm, bed width 120-150cm, aisle 20-25cm, spacing 15cm, ditch depth of about 5cm, seed use per acre 8- Twelve kilograms, uniform thickness (about 1.5-2cm), then cover the straw, fill the water, and catch the shade net. Fourth, field management When the emergence rate reaches about two-thirds, weeds will be removed, weeding and weeding will be resumed, and weeding should be done as early as possible, small and sturdy. At the same time, in order to prevent seedlings from leaf blight, Seedlings are sprayed with 1:1:100 Bordeaux mixture, sprayed once a week, and sprayed 2-3 times per week. When the seedlings grow to 5-6 leaves, they can be transplanted in a rainy day. And timely shade watering. Fertilizer is mainly used N fertilizer foliar spray fertilizer concentration of 1-2% once every half months, about 5-6 spray. When the seedlings grow to a height of about 30cm, the overgrown seedlings should be picked in time to promote the robust growth of the seedlings. After the beginning of autumn, the temperature gradually decreased, and the shade net was lifted on rainy days. N fertilizer was stopped at the same time, and 0.3% of potassium dihydrogen phosphate was sprayed 2-3 times every 7-10 days to promote lignification of seedlings.
Drugs used in diabetes treat diabetes mellitus by lowering glucose levels in the blood. With the exceptions of Insulin, exenatide, liraglutide and pramlintide, all are administered orally and are thus also called oral hypoglycemic agents or oral antihyperglycemic agents. There are different classes of anti-diabetic drugs, and their selection depends on the nature of the diabetes, age and situation of the person, as well as other factors. Antihypertensives are a class of drugs that are used to treat hypertension (high blood pressure). Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Jinan Jianfeng Chemical Co., Ltd mainly manufactures the antihypertensive pharmaceuticals and Intermediates such as Voglibose, structure as the following:
