Propagation and cultivation methods of annual herb Portulaca oleracea

Portulaca oleracea, also known as horse amaranth, ant vegetables, Anle vegetables, sour rice vegetables, longevity vegetables, melon seeds vegetables, five elements vegetables, horse snake seeds, horses, vegetables, belongs to the annual herbs of Portulaca oleracea. The root system is stout and developed. The stem is upright, inclined or procumbent, and the branches are cylindrical yellow-green, and the sunny side is reddish brown. Leaves alternate or opposite, obovate or spatulate. The whole plant is thick and juicy, smooth and glabrous. The flowers are five yellow flowers. Fruit a conical capsule. Seeds small, oblate, dark brown, the surface has a small tubercle shaped process.

Portulaca oleracea is drought tolerant, waterlogging tolerant, strong light tolerant, and fond of fertile water. It grows faster in fertile soil and has good quality. It can also grow normally in poor soil. The suitable temperature for growth is 20-30℃, like dry air and humid soil environment, grow fast and tender in weak light, easy to grow in rainy days, such as too strong light is easy to age. Sandy loam is the best soil.

Wild purslane is mainly distributed in fields, wasteland, roadsides and courtyards, especially in hillocks and sand dunes.

1. seed propagation

The seeds can be sown at temperatures above 15 DEG C. Before sowing, soil preparation and fertilization should be carried out first. 2000 kg of decomposed base fertilizer should be applied per mu. After ploughing, flat beds of 1.2 meters should be made, and sowing should be carried out on the basis of wet soil. 700 grams per acre. Because purslane seeds are too small, seeds can be mixed with 5 times the fine sand and then broadcast, covered with fine moist soil 0.5 cm thick after sowing. Early spring season, in order to prevent cold, after sowing should be covered with plastic film or grass, in order to keep warm moisture. When the seedlings emerge, the film should be removed or the cover grass removed. If sowing in summer, in the early stage of seedling emergence, should buckle sunshade net, and timely weeding and drainage of rain. In the case of good soil moisture, seedlings can emerge 2-4 days after sowing. After 10 days of emergence, thin seedlings with plant spacing of about 5 cm. Then water and fertilize, apply urea 10 kg per mu, and remove miscellaneous leather in time. About 30 days after sowing, the stems and leaves fully grow up, and harvest at the tender stage before flowering and budding. If seeds are needed, they should be harvested before the fruit opens, otherwise the seeds will open and fall when they mature.

2. Sub-root propagation

Dig up the roots of the grown plants and divide them from the base of the roots, so that each divided plant has a proper amount of fibrous roots and lateral roots. After drying for a little, you can plant them in the beds, or you can dip them in rooting powder solution first, and then plant them. When planting, one stem should be buried in the soil, and the plant spacing should be 10 cm ×10 cm. Cover soil after planting, slightly suppress and water again, generally after 3-5 days can slow seedlings. After slow seedling, can force fertilizer watering, in order to promote the growth of stem call.

3. layering propagation

Press the longer stems and branches on the ground around each plant, and press 1 stem node with tidal soil every 3 nodes (2 - 1 stem nodes should be reserved in front of the soil pressure) to make it take root in the soil. When the stem node at the pressing soil takes root, it can be separated from the main body, so that a new independent individual can be formed.

4. recovery

Generally, the stems and leaves can fully grow up about 1 month after sowing or planting. When the stem. Ten thick hypertrophy tender juicy, to take advantage of the bud before timely harvest. If it has budding, it should be removed buds, and then washed with water, tied to the market.
