The latest propagation method of green pineapple

Green pineapple grows in the tropics and often climbs on the rocks and tree trunks of the rainforest. it has strong entanglement, well-developed air roots and can be cultivated in water. Green pineapple is usually propagated by cuttings. Let's take a look at the breeding methods of green pineapple.

The method of striping propagation of green pineapple

Green pineapple striping propagation is the most successful propagation method. The stolon is pressed into the soil, and the ramet can be cut after the air root is produced.

Method of water insertion and propagation of green pineapple

Green pineapple can also be inserted with terminal bud water, first cut the tender stem vine 20~30cm into a section, directly insert into the bottle of water, change water every 2-3 days, more than 10 days can take root and survive. Due to the limitation of potted soil, potted green pineapple is easy to aging and its leaves become smaller and fall off after being cultivated for a long time. Therefore, it is necessary to change the basin or prune and renew after 2 to 3 years of cultivation.

Cutting propagation method of green pineapple

Green pineapple is usually propagated by cutting. Select robust green radish vine in late spring and early summer, cut 15 cm to 30 cm branches, remove the leaves of 1 to 2 nodes at the base, be careful not to hurt the air root, and then insert into the plain sand or cinder, the depth is 1 Rue 3 of the cuttings, drench enough water to place in the shade, spray water to the leaves every day or cover with plastic film to moisturize, as long as the environment is not less than 20 ℃, the survival rate is above 90%.

1. Selection and treatment of cuttings: cuttings should choose semi-lignified branches with strong growth and no diseases and insect pests, cut into 10-13 cm long, cut into oblique notches at the bottom, leave 2-3 leaves at the upper end, and cut off half of the leaves to reduce water evaporation and facilitate the survival of cuttings.

2. Cutting substrate: the cutting substrate requires loam or sandy soil with high humus content, which is loose and breathable, well drained, and preferably vermiculite, which can take root quickly and have a high survival rate. Disinfect the soil with 2% formalin or 5% potassium permanganate before insertion.

3. Cutting method: the lower end of the prepared cuttings was quickly dipped in ABT rooting powder or indolebutyric acid, then inserted into the prepared substrate, put into the soil, poured water, so that the cuttings were in close contact with the substrate, and then covered with plastic film.

4. Plug-in management

Pay attention to keeping the soil moist and high air temperature after ① insertion. The soil moisture is about 50%, while the air humidity is 80% and 90%.

At the initial stage of ② cutting, the shade degree of the shade shed is kept at about 80%, which can not only prevent strong direct sunlight, but also ensure sufficient scattered light, so as to facilitate photosynthesis and rooting of leafy cuttings.

Through the above treatment, ③ basically takes root after 20 days, and the film can be removed to increase the light. at the same time, attention should be paid to foliar spray and shade on sunny days in summer, cold prevention in winter, and normal management in the basin about 10 days after rooting.
