Pineapple drawing steps are as follows:

Preparation materials: paper, colored pens

1, first draw the shape of the pineapple with a black pen, the top plus the leaves.

2, then draw the second layer of leaves at the top.

3, Paint the pineapple with yellow color.

4, paint the first layer of leaves with light green color, and the second layer of leaves with dark green color

5, paint the details of the leaves, a bit of dark shadow on the right side of the pineapple, a stroke of highlight on the left side, and finally the pulp.

Pineapple (Ananas comosus Merr.) is a terrestrial herb of the genus Pineapple of the family Pineapple, with a short stem; most leaves, with a rosette-like appearance, sword-shaped, the leaves borne on the top of the inflorescence become smaller, often red; petals long oval, pointed at the end, purple-red on the upper part, white on the lower part; the flowering period from summer to winter.

Pineapple is native to the South American tropics, the early 18th century spread throughout the European countries, China's introduction of pineapple plant cultivation has a long history of 300 years. Pineapple sun-loving, drought-resistant, like high temperature, high humidity environment, summer like cool, ventilation. Pineapple is propagated by seed, asexual propagation and plant division.

Propagation:

Pineapple usually takes 3-4 months from flowering to seed maturity. Pineapple seeds are very small and a single fruit can produce dozens of seeds and 1 plant can produce thousands of seeds. The sowing method of pineapple can be used indoor pot sowing or seedling tray sowing. The sowing substrate can be a mixture of river sand, perlite and peat soil, which must be sterilized at high temperature before sowing.

Spread the seeds on the surface of the substrate after a light pressure, without covering the soil, covered with plastic film or glass moisturizing can be. In the germination temperature of 24 ℃ -26 ℃ conditions, about 7-14 days of germination, live seedlings with 3-4 true leaves can be transplanted in 4-5 cm pots.

Split-plant reproduction is often carried out in the spring, the survival rate of split-plant during the high temperature is low. Cuttings, when the tiller 8-10 cm cut off, inserted into the substrate of half of the rotting soil and coarse sand, maintain room temperature 25 ℃ -28 ℃, about 30-40 days can be rooted, 50-60 days can be potted cultivation. The mother plant that breaks off the tiller can grow another 2-3 batches of tillers after raising the plant.

To make the mother plant grow more tillers, must be properly maintained, the best ground planting, frequent fertilization, and give more adequate light. In addition, the bromeliad tiller cut sooner or later and reproduction coefficient has a greater relationship. The later the division, the larger the daughter plant, the higher the survival rate, the faster the daughter plant growth, but when the division is too late, it will also affect the mother plant to further reproduce new shoots. Divided seedlings can be cultivated for 2-3 years to bloom.
