Morphological characteristics of Princess tree

Branches: Princess trees are deciduous trees, but evergreen in the tropics, crown conical, umbellate or sub cylindrical, bark smooth and marked lenticels when young, divided longitudinally when old.

Leaves: Leaves are opposite, large and long-stalked, sometimes 2-3 whorled on vigorous new branches, heart-shaped to long ovate-heart-shaped, base heart-shaped.

Flowers: The flowers are trumpet-shaped in small cymes with large purple or white corolla.

Fruit: Capsule is ovoid, ovoid elliptic, elliptic or oblong, locularis dehiscent, 2-lobed or incomplete 4-lobed, pericarp thinner or thicker and lignified; Seeds are small and many, membranous wing, with a few endosperm.

Princess tree growth environment

Princess tree is a positive species and has strong adaptability to viscous barren soil. They grow very fast and are fast growing species. It is most suitable for growing in the sandy loam or hard soil with good drainage, deep soil layer and good aeration. It grows well in the mountains, hills, hilly lands and plains below 1200 meters. It’s drought resistance ability is strong, pH 6-8 is better, magnesium, calcium, strontium and other elements have the tendency of selective absorption, so more nitrogen fertilizer increases the application of magnesium, calcium, phosphate fertilizer. Because of its strong adaptability, Princess trees can generally grow in soils with strong acidity or alkalinity, but avoid water accumulation. Princess trees are easy to reproduce, and the method of planting roots and seedlings is more common.

Princess tree growing methods

Princess tree has a long history of cultivation, the name of the genus.

⑴ Choose a good seed. The commonly referred to Princess tree is actually the general name of the genus Princess Tree. There are 9 species in the genus, and the species suitable for growing in the south are Princess Whitefloor or the hybrid species with Princess Whitefloor as the parent. Six Princess Tree clones were bred by Fuzhou Forestry Research Institute of Jiangxi Province. They grew rapidly, were straight in dry form, were tall in trunk under branches, and had strong adaptability. They were excellent lines suitable for popularization in the south of the Yangtze River.

(2) The roots are buried and the seedlings are raised. Seedling to leeward sunningdale, predominantly silty loam or loam soil, high 15 ~ 20 cm high ridge seedbed, choose 1 ~ 2 years MiaoGen, buried root, for good, buried root plant row spacing to 1 m * 0.8 m or 1 m * 1 m advisable, sufficient basal, exuberant growth period in June to August, topdressing quick-acting chemicals to promote its rapid growth.

(3) Afforestation. Afforestation by the four sides requires digging holes and applying sufficient base fertilizer. Afforestation in mountainous areas requires preparing the land in strip terraced fields. The thickness of the loose soil layer should be 50-70 cm, and sufficient base fertilizer should be applied to achieve the purpose of rapid growth of afforestation in the same year. Forest-dominated afforestation density is 5 m ×5 m, 26 plants per 667 square meters (1 acre); The afforestation density with equal emphasis on forest and grain was 5 m ×10 m, and 13 plants were planted every 667 m2. The density of grain-based afforestation was 4 m ×30 m, and 6 plants were planted per hectare.

Princess tree main value

Princess tree varieties, wide distribution of a large range of afforestation. The growth is fast, volume is much solve lumber supply shortage problem, is a deep - rooted tree species, suitable for large - area farming and tung interplanting. Wood is light and good, widely used in all aspects. Leaves and flowers are rich in fertilizer and nutrients for fertilizer and fodder. Leaves can also lure and kill pests. Leaves, flowers, fruits, bark can be a pharmaceutical treatment of tracheitis, curative effect is remarkable, improving the ecological environment.
