The latest breeding methods of Portulaca oleracea

Purslane is an annual herb with wide distribution and strong adaptability to life. it often grows on the roadside, in the field, is a kind of wild vegetable that people often eat, and the whole grass can be used as medicine, which can clear away heat and detoxify. Its main propagation method is sowing and cutting. because the branches and leaves are full fleshy stems, the cutting is easy to survive. Let's introduce it to you now.

First, sowing and reproduction

1. Land selection and preparation

Choose fertile and moist land, it is best to take shelter from the wind and the sun, sow seeds in high-lying places, and then the soil should be improved into a loose, fertile, well-drained soil without stagnant water. The main purpose of land preparation is to turn the ground about 25 centimeters first. The distribution of root system is not deep, the soil is turned too deep, and the subsoil has no nutrition. Then it is necessary to compost about 1300 jin of grass per mu to increase soil fertility. After mixing the soil and fertilizer, cover the topsoil, and the topsoil can be ploughed fine.

2. Sowing and raising seedlings

The seed is small and the seed coat is not thick. Can directly sow seeds and raise seedlings, the time will not be too long, there is soaking seeds in hot water, easy to scald seeds. The nursery bed is selected to make a part of the bed next to the field, with a width of 1.3 meters and a length of no more than 5 to 6 meters, affecting drainage. Small seeds are generally spread directly and evenly on the bed surface, and then covered with soil within 1 cm of depth. Spray water, do not use a hose to water, the seeds are easy to wash away. Seedling raising in small arch shed can keep warm and moisturize, and seedling emergence is fast, but pay attention to ventilation, easy to burn seedlings, seedling raising in greenhouse is relatively relaxed.

3. Seedling emergence management

Keep moist every day, spray water every day, can be a small number of times, not retting, and then will emerge in a week or so, the middle of the small arch shed should be ventilated at noon during the day, short ventilation, the greenhouse can not be ventilated. After emergence, it can reduce moisture and prevent diseases. Seedlings grow 3 to 4 true leaves can be transplanted, transplanting ridge planting, ridge row 20 cm wide, row spacing of 15 cm can be. Slow seedlings should be applied with light fertilizer and water to take root and recover as soon as possible.

2. Cutting propagation

Take branches on the same year or wild seedlings, choose strong germinating plants to pick branches, do not hurt the plants, but also easy to survive, take branches to leave 3 to 5 nodes, short and strong branches are better. Making a seedbed in the greenhouse is similar to sowing a seedbed. Then the soil should be fluffy and covered with farm manure after covering the topsoil, first irrigated with water, then punched with a stick after cutting branches, about 3 cm cuttings, plant spacing 3 cm line spacing 5 cm. After moisturizing, shading, about a week later survive.

The above is the introduction of the breeding methods of purslane. I hope hopeful friends can gain something after reading. That's all for the specific introduction.
