Propagation method of Penglai pine

Penglai pine stems and branches tall and straight, green dripping, is one of people's favorite home green plants, many people choose Penglai pine green plants. Penglai pine is very popular because of its beautiful shape and verdant leaves. Potted plants are displayed on the coffee table and desk, adding a bit of elegance to the room.

Penglai pine can be propagated in multiple rows and can also be sown, but it grows slowly at seedling stage.

1. Ramet propagation: this method is multi-purpose. It can be carried out when changing the basin in spring and summer, knock the dense old plants out of the basin, cut the underground roots into several clumps, make each clump contain 3 to 5 branches, and pay attention to the least damage to the roots, re-plant each clump with newly cultivated soil, pour water through it, and put it in a semi-shady place to restore growth.

2. Sowing and propagation: the seeds are generally sowed indoors. After the seeds are ripe in March to April, they are sowed with picking and sowing in a shallow basin, covered with thin soil, soaked in water and covered with glass. Generally, they germinate in about 20 days. When the seedlings are 5-8 cm high, they can be planted in pots for maintenance.

Penglai pine is often propagated by sowing method or split-plant method, which is generally sowed indoors. After the seeds are ripe in March-April, the seeds are sowed with clear water for 1 day before sowing, sowed in a shallow basin with a distance of about 1 cm, covered with thin soil, covered with glass after soaking in water, and germinated for about 20 days. When the height of the seedling is 5-8 cm, it can be planted in a pot. Ramet propagation can be carried out in combination with changing pots in spring and summer, and the mother plant can be divided into several clusters. When ramets should be operated carefully, be careful not to hurt the root, stem, skin too much, and then according to the size of the plant into the corresponding basin.

Artificial reproduction:

Like warm, humid and semi-shady environment, more drought tolerance, strong cold tolerance. It is not strict to the soil, like the sandy loam with good aeration and drainage and rich in humus. The suitable temperature for growth is 20 ℃ and 30 ℃, and the overwintering temperature is 3 min.

Seedling propagation:

Penglai pine uses multi-purpose seeds to raise seedlings and propagate, and the germination rate can be as high as 90%. It can be picked back in time from mid-September to mid-October when the cones are ripe, first stacked for 5-7 days, then exposed to the sun for 3-4 days, beating and turning, seeds protruding, timely water separation, removal of empty sundries, and bag storage after drying for the winter. Penglai pine has thick seed coat and slow germination, so it is suitable for early sowing. The slightly acidic soil with good drainage is selected in the nursery, and sufficient base fertilizer is applied when preparing the soil.

Before sowing, the seeds were soaked in cold water for 3-7 days (the water should be changed during soaking). After soaking, the seeds were mixed with hydrated lime, and the seeds could be sowed after the seed coat was cracked. It began to sprout and unearthed in the middle and last ten days of April, and the seedlings of that year could reach 812 cm.
