Selection and cultivation of bonsai of Pinus taiwanensis

Huangshan pine is green, vibrant, with erect branches, straight up, thin leaves such as needles, comb the wind to cover the green, evergreen all seasons, is one of the best ornamental pine species. Bai Juyi, a great poet of the Tang Dynasty, once praised his character and said: "Pine on the Pavilion, a lifetime of sunrise, towering on the forest, a hundred feet long; the twilight is covered with snow, and the color is green; he is like a gentleman with a heart of ice."

Pinus tabulaeformis, the scientific name of Pinus tabulaeformis, is an inherent tree species in China, evergreen trees, widely distributed in the vast area south of the Huaihe River in China, the treasure island of Taiwan can also be seen, with the beauty of Huangshan and famous all over the world. Now the State Forestry Administration has officially named it (Huangshan Pine), and Zhejiang is used to calling it Tianmu Pine. As bonsai lovers, they are all dazzled by their old age, oddity, extensive management and long life span (up to hundreds of years).

Artificial reproduction:

Huangshan pine uses multi-purpose seeds to raise seedlings and propagate, and the germination rate is high, which can reach 800.85%. When the cones were yellowish brown from late November to early December, the full cones were collected from the sturdy mother tree with dense canopy, and the seeds were removed. After about 10 days of sun exposure, the seed scales crack, remove wings and remove impurities, bagged and stored in winter.

"the Spring Equinox" before and after sowing, the nursery with loose soil, good drainage of acid soil is better. Spraying 75% pentachloronitrobenzene or potassium permanganate solution to disinfect the soil. Wet the seeds with water before sowing and then mix the seeds with calcium magnesium phosphate fertilizer. 1 kg of seeds mixed with 0.5 kg of calcium magnesium phosphate fertilizer. After sowing, it was covered with fine soil for about 2 cm, then covered with grass, and began to sprout and unearthed one month later.

In June, you can apply thinly rotten acquaintance urine, wash the seedling leaves with clean water, and then spray 0.5% Bordeaux solution to prevent the disease. The peak period of seedling growth is from July to August, and the growth stops in late September, and the seedlings can reach about 20-25 cm in that year. Potted plants can choose 2-3-year-old stout saplings for processing and modeling.

Mountain mining:

Huangshan pine is easy to renew naturally. It can be planted in the rock crevice, ridge and slope of the mountain above 700 meters above sea level. The wild seedlings of Pinus taiwanensis which grow stout and dwarf are selected in the mountains, with flat branches and short and dense needles, which is convenient for pot modeling in the future.

It is necessary to cultivate in the field in time after mining, and cut all the needles by half before planting to reduce evaporation. It should be cultivated in places with sufficient light, good ventilation and barren and thin soil. To control moisture and nutrients, Reed curtains should be used for shading in summer, cover late and early, and spray water once or twice a day to keep the topsoil moist. After 2 years of cultivation, it becomes a good bonsai material.

The mining season should be after the Mid-Autumn Festival in the lunar calendar to before Lesser Snow or after the Beginning of Spring to the Spring Equinox. Most of the materials suitable for basin growth grow on rock layers with an altitude of more than 1000 meters, and young and old trees are generated due to the adverse environment for many years, which is a good material for bonsai production.

When mining, we should pay attention to protect the root system, host soil and wrap it tightly with cloth to facilitate moisturizing and transportation, and try not to cut off the main root. When planting, first nail the appropriate wooden box according to the size of the root plate, select weathered mountain sand to plant, select the thicker ones and put them at the bottom for drainage, and then insert them layer by layer with chopsticks. At this time must not hurt the root and rush to take the root on the basin, to survive 1-2 years can be on the basin normal maintenance. If the survival rate can be correctly grasped, it can exceed 100pm 80-70.

In maintenance, the fixed root water is poured once after planting, and then the dry temperature can be seen. The needles can be sprayed according to the air temperature and sunshine, but not below 10 degrees, generally 3-4 times a day, and the times of spraying water can be increased moderately above 30 degrees. Huangshan pine is a positive plant, there is no need for sunshade after loading, the basin soil can keep 100ppm 50 humidity, avoid stagnant water at the root. For example, the blanks collected in autumn and winter should be covered with thin film to keep warm when the temperature reaches 2 degrees below zero, so the original roots in winter are cold-proof when there are no new roots, and there is no need to filter and prevent freezing after survival.
