First, the medicinal value of purslane, also known as longevity grass, five elements of grass, claw food, etc., is the entire annual purslane, the annual succulent herbal purslane, is a traditional Chinese medicine, with scattered blood, swollen, cool Blood slippery bowel, detoxification Tonglin, governance postpartum sweating effect, attending dysentery, sores, uterine bleeding, external use can cure erysipelas, snake bites embolism. The purslane can be used for both medicines and foods. Its nutritional value and medicinal value are high. It contains large amounts of L-desmethyl adrenaline and dopamine and a small amount of dopa. It also contains vitamins B1, B2, P, C, and carotene. Potassium salt.
Second, the growth environment of purslane like hi-temperature and high humidity, cold, resistance to turbidity, with positive, suitable for cultivation in various fields and slopes, with neutral and weakly acidic soil as well. It can be cultivated from spring to autumn, the spring sowing starts later, and the quality is soft. Summer and autumn seeding easy to flower quality rough old, generally 2 to 8 months can be sown. The germination temperature is 18 °C, the most suitable growth temperature is 20 ~ 30 °C, when the temperature exceeds 20 °C can be sowed in stages, one after another market. Protected cultivation can be produced periodically.
Third, breeding methods can be divided into seed propagation and cutting propagation.
1. Seed propagation After the frost breaks in the spring, the seeds can be sown in the open field. The seeds used are all the seeds that were collected or cultivated from the field in the previous year. If they are to be listed in advance, they can be transplanted in protected areas. Choose land plots with flat terrain, convenient irrigation and drainage, and less weeds. Deeply turn over the ridges, apply organic fertilizer, and then make the car. The seeds of purslane are very small, so the basal fertilizer must be applied before sowing, and then the cultivator can be used to make a 1.2m-wide cabin. The surface of the purslane should be flat and the soil should be fine. In order to ensure that the seeds are spread evenly, the seeds can be mixed with fine soil and then sowed. After sowing, the surface of the car is properly compacted and then watered for 7 to 10 days. Protect the seedlings on the protected land, cover the mulch and cover shed after sowing, and remove the mulch immediately after emergence. When the seedling grows to 3~4cm in height, the seedlings will be started and the seedlings will be divided and gradually increased. Nursery field seedlings above 5CM can be transplanted. Generally about 700g per acre sowing seeds, seedlings about 500g.
2. Cutting propagation Cutting branches are collected from the seedlings or wild seedlings of the year, and collected from strong plants with strong growth and strong growth. Each section should have 3 to 5 sections. Before the cutting, we must finely cover the soil, apply enough base fertilizer, and make a car with a width of 1 to 1.2m after cultivating, and then cut the unflowered seeds into stem segments with a length of about 5cm or the branch cutting density (row spacing) of 3cm5cm. Insert a soil depth of about 3cm, and maintain a certain degree of humidity and appropriate shade after plugging it in. After a week, it can survive and be top-dressed after being rooted.
Fourth, field management sowing or cutting 15 to 20 days can be moved into the field cultivation, when the cultivation area is small, can also be directly inserted into the field. Before the transplanting, the soil shall be plowed, combined with 1500kg fully decomposed human or animal manure per acre, or 15-20kg of compound fertilizer per acre, and then the plant shall be planted at a spacing of 15cm20cm by planting 1.2m wide and then soaked. water. Transplanting is best done on a cloudy day. If transplanting on a sunny day, shady measures should be taken within two days after planting, and watering should be done once a day in the evening. After transplanting base fertilizer as required, no fertilizer may be applied in the early stage. After each harvest, one or two times of thin human waste water is chased. During the growth period, a little nitrogenous fertilizer is often applied, and the stems and leaves can grow thick and thick and increase the yield. Delay reproductive growth and improve quality. The buds formed should be removed in time to promote the cultivation of vegetative shoots. Water should be properly watered during drought, and weeding should be done during growth. The purslane rarely suffers from pests and diseases, and generally does not require spraying.
V. Harvested purslane is harvested several times in one sowing, harvesting is picking. Harvesting standards are shoots 10 to 15 cm long before flowering. Newly emerged leaflets are the best edible parts. The tips of the shoots can be continuously picked up, and the middle and upper parts are taken. , Harvesting can be harvested 15 to 20 days apart until frost.
VI. Seed-reserving, Seed-collecting and Processing The purslane-retained farmland can be planted alone, or it can be drawn from the plots that produce commercial vegetables, properly sparsely planted, and strengthened in management. It is not possible to harvest commercial vegetables and leave them natural hair, flowers, and seeds. After the pod period of the pod has matured, it is 20-30 days after flowering. When the pod (seed husk) is yellow, the seeds are mature and should be harvested in time, otherwise they will be scattered on the ground. Its seeds are very small. During collection, waste paper or film can be laid between rows or between plants. After shaking the plants, the seeds are dropped on waste paper or film and collected again. In addition, if purslane is planted in a greenhouse, it can be sown early in the spring or planted in order to seize the market. In the autumn, cultivation should be postponed to supplement the off-season vegetable garden; after harvesting, impurities are removed, washed, and then steamed or hot Sun dried.
