The value and cultivation of purslane
The purslane, also known as the horse leeks and long ribs, belongs to the annual fibrous succulent plant of the dentate family and is often found in gardens or in wasteland. The purslane is native to India and has spread throughout the world for centuries. It has its wild type in Europe, South America, and the Middle East. In the United Kingdom, France, the Netherlands, and the United States, cultivars have long existed. In our country, the wild species are the dominant species. The wild resources in Tianjin are relatively abundant. The purslane has strong adaptability, heat resistance, drought tolerance, and the requirements for light are not strict. Strong light and low light can all grow normally. It grows well in warm, moist, fertile loam soil or sandy loam soil. It can grow in any soil and can store water, ie it is drought tolerant and resistant to earthworms, just like other weeds. Strong vitality, just a little management can grow very well. First, the use of value 1. Consumption. The purslane is eaten as a vegetable and has rich nutritional value. It is a variety of nutrient sources needed by the human body. It is determined that every 100g of fresh grass contains: Vitamin C 23mg, 0.03mg VB1, 0.11mg VB2, Carotene 2.33mg , Niacin 0.7mg, protein 2.3g, fat 0.8g, carbohydrate 3g, crude fiber 0.7g; inorganic salt content is also higher, calcium 85mg, phosphorus 56mg, iron 1.5mg; Potassium oxide potassium, fresh grass About 1%, hay contains about 10%. In addition, purslane also contains malic acid, a variety of amino acids and traces of free oxalic acid. The consumption of purslane in our country has been known since ancient times, but the folk tradition of the method of eating is relatively simple, the collected stems and leaves, boiled soft with boiling water, and then cook soup, fried or salad. Can also be boiled with hot water, dry to half dry, and then make stuffing with other raw materials. Some areas are being tested for deep processing, such as the purslane root cut into 6 ~ 8cm section, made canned, can be long-term preservation. It can also be stored frozen and used as fresh vegetables after defrosting. The purslane's tender stems can also be marinated into good condiments. 2. medical insurance. Many scientists found that purslane contains high concentrations of norepinephrine, which contains 25 mg per gram of fresh weight. It also contains dihydroxyphenethylamine and dihydroxyphenylalanine, which are precursors of norepinephrine. And intermediate components. Norepinephrine promotes the secretion of insulin and regulates the process of sugar metabolism in the human body, which has the effect of lowering blood glucose concentration and maintaining blood sugar stability. Therefore, eating purslane often has a therapeutic effect on diabetes. Purslane is rich in VA and can promote the physiological function of epithelial cells to normal and promote the healing of ulcers. Purslane has inhibitory effects on dysentery bacillus and typhoid bacillus. Folks often use single-taste decoction or fresh grass to smash. Take a glass of juice and add a little rice wine to treat diarrhea. The whole plant also has an inhibitory effect on common pathogenic dermatophytes. It is washed with fresh grass and smashed on the outside or single-boiled, or with odoriferous indigo leaves 50g decoction. It can treat eczema, rice field skin moxibustion, and can also treat poisonous snake bites. Injury, lymphatic tuberculosis, acute appendicitis, acne, etc. In addition, the content of VE in fresh purslane is 0.2%, 5 times higher than that of pineapple, which helps the body to resist aging. Second, cultivation techniques 1. Sowing or planting. The seed was collected during the flowering season of wild purslane and exposed live in the spring after the frost had bloomed in the spring. It was also possible to nurse the seedlings in the protected land, transplant the seedlings after the frost, and harvest early. Sowing method or sowing is used for the sowing method. Because the stems and stems grow around, the planting density should not be too large. After the seedling grows, the seedlings should be kept continuously so that it grows faster and stronger. 2. Cut stem segments. The stem root ability of purslane is very strong, stem segments can be used for cutting, picking some stem segments from the field or planting fields, watering after planting, proper shading can survive. 3. Field management. The purslane is in a wild state for a long time. It is very adaptable and easy to manage. To make the purslane tender, a certain amount of manure should be applied. In addition, during the growing season, some nitrogen fertilizer should be added. Due to its strong drought tolerance, under normal circumstances, no watering is needed, and some water should be added when it is particularly dry. In the initial stage of planting, appropriate cultivators and weeds should be used. Once it grows, other weeds will be difficult to survive and will be virtually free of pests and diseases. Perennial purslane is an annual plant that enters its annual flowering results in June. If no seeds are left, the stem buds can be partially removed to promote new branches and increase yield. In order to continue growing in the next year, you should leave some flower buds as appropriate. The seeds naturally fall on the ground, and they can sprout and grow in the second year. When they are planted once, they can grow continuously for several years without having to plant them every year.
