I. Cuttage

Cuttings select current year's twigs, 12 to 15 cm long, with full buds, cut off half of the upper 2-3 leaves of the cuttings, and remove the lower leaves. The cutting depth is 4 to 5 cm (that is, 1 to 3 of the length of the cuttings), and the cuttings are watered after cutting to make the cuttings closely combine with the substrate. Cover the insert bed with plastic film, maintain a certain humidity in the insert bed, water it 2 to 3 times a day, and take root in 50 to 60 days.

Second, sowing seeds

1. Seed treatment seeds were sandy stored in mid-November and began to germinate after mid-March of the following year. The temperature should be 10 to 25 degrees Celsius. Germination began in the first and middle of April, and the germination rate reached 72% after mid-April.

2. Sowing and loosening the soil, making the border surface flat and irrigating, waiting for water to lag behind, sowing with water method, row spacing 25 cm, seed spacing 3 cm, soil thickness 1.5 cm, covering film after sowing to keep warm and moisturize and prevent seedlings from being damaged.

3. Seedling stage management: in the early stage of seedling emergence, in order to accelerate germination, prevent wind and frost and ground hardening. Mid-late May seedlings can be up to 1 cm high, a leaf, at this time began to shade, to prevent sunburn. In order to prevent leaf spot and seedling yellowing, carbendazim can be sprayed and appropriate amount of fertilizer should be applied. In addition, weeding, loosening the soil and irrigation must be timely. Through the comparison of shading and full light, it is proved that the leaves of shading seedlings are extended, larger and grow stronger. The growth is slow throughout the summer. In early September, as the sunshine weakened, the weather became cooler and the shade was removed. At this time, the seedlings are as high as 4 to 5 centimeters, grow 4 to 5 leaves, and grow strong. In late October, the seedlings shed leaves, stopped growing, protected against cold in winter, and stopped fertilization and irrigation.

The propagation method of Tiannu flower

Whether it is a piece of scenery, or embellished in the basin, Tiannu flower has an elegant temperament.

The Cuttage Propagation method of Tiannu Flower

Before cutting, we must first prepare the soil. Cultivation is generally available in sandy loam, and fertile soil rich in deciduous humus is the best.

When cutting, we should choose the twigs that grew in the same year, the length of which is 12muri 15cm. All the leaves at the lower end are removed, while the leaves at the upper end can be cut by half. Insert 4 to 5 centimeters of soil.

After the cutting is finished, it is necessary to pour enough water and cover the surface with a layer of plastic film to ensure the moisture of the soil. Then, water moderately 2 times a day and 3 times a day and wait for a month and a half to take root.

Sowing and Propagation methods of Tiannu

The best sowing season for Tiannu is after the temperature warms up in mid-March. Warm weather can guarantee a certain germination rate.

The soil should be loosened and leveled before sowing. And irrigate thoroughly, wait for the water to be absorbed by the soil, and then bury the seeds at a depth of 1 Murray 2 cm. It should also be covered with plastic film.

When waiting for new seedlings to grow, you should pay attention to shading to prevent sunburn.

Breeding Management of Tiannu Flower

Tiannu flower is a small deciduous tree of Magnolia of Magnoliaceae. The branches are slender and glabrous, and the branchlets and buds are pilose. Leaves broadly elliptic or Obovate-oblong, 6 to 15 cm long, with powdery back, lateral veins 6 to 8 pairs. Flowers white fragrant, solitary branch top, flower stalk quite long, in full bloom floating with the wind, fragrance to the nostrils, just like Tiannu scattered flowers, hence the name Tiannu flower. The florescence is from the first ten days of June to the middle of July, and the fruit ripening period is from the first to the middle of September.

Sexual preference for cool and humid climate and fertile soil, propagation methods commonly used cutting, sowing, can also be grafted, ramet.

First, cuttings: cuttings select current-year twigs, 12 to 15 cm long, with full buds, cut off half of the upper 2-3 leaves of the cuttings, and remove the lower leaves. The cutting depth is 4 to 5 cm (that is, 1 to 3 of the length of the cuttings), and the cuttings are watered after cutting to make the cuttings closely combine with the substrate. Cover the insert bed with plastic film, maintain a certain humidity in the insert bed, water it 2 to 3 times a day, and take root in 50 to 60 days.

2. Sowing: 1. Seed treatment: seeds are stored in the middle of November and begin to germinate after the middle of March of the following year. The temperature should be 10 to 25 degrees Celsius. The germination rate will reach 72% after the middle of April.

2. Sowing: prepare the ground and loosen the soil, make the border flat and irrigate, wait for the water to lag behind, sow the seeds with a row spacing of 25 cm, a seed spacing of 3 cm, and a soil cover thickness of 1.5 cm, covering the film after sowing to keep warm and moisturize and prevent seedlings from being damaged.

Late October. Seedlings fall leaves, stop growing, prevent cold in winter, stop fertilization and irrigation.
