Paulownia

Paulownia Sps

Paulownia sps are trees belongs to the family Paulowniaceae, native to Asia.

This species can withstand a very wide range of environmental conditions but it does not grow at higher altitudes

Most species of Paulownia are fast growing as the harvesting begins within 8-10 years and can continue yearly for as long as is desired.

The tree is extremely hardy and its plantation requires only minimal inputs from the grower. The plant's leaves are very large and pubescent.

Why Paulownia For Plantation :

Paulownia is a soft lightweight, air curable wood, that does not warp, twist, or crack with excellent machining and finishing Properties. The tree is fire resistant and water repellent.

Paulownia can be sold for pulp, paper, poles, construction material, plywood, and furniture and at top dollar. You still have to be lucky enough to be growing the trees in an area with a good market.

Paulownia can be commercially harvested in five to seven years. This is true but only for some products made by companies that may or may not be buying at any given time.

Paulownia is a beautiful tree and is easily propagated from root cuttings. But it can also become a problem in the landscape because of its messy habits.

Paulownia is nitrogen rich and makes an excellent livestock fodder and soil amending mulching material.

Tissue Culture Technology

Efficient vegetative micropropagation has been demonstrated to have many advantages over seedling propagation of Paulownia sps.

The in vitro propagation techniques provide healthy, homogeneous planting stock for a forestation and woody biomass production of Paulownia.

Soil : Paulownia is highly adaptive species and grows well on many types of soils. Most appropriate and recommended are light, well drained and sandy soils with or without slopes. The soil pH is from 5.0 to 8.9

Climate : Paulownia can adapt to a wide range of temperatures. The development starts in the spring, when the soil temperature reaches 15-16оС.

Planting : For effective yields we recommend the trees to be planted with higher density than the one used for timber production.Larger density leads to competition for area between the trees and slower their growth after the first 3-4 years. Lower density leads to faster initial growth which lowers the timber quality. Higher density does not lead to commercial effect, the necessity of elimination of plants is connected with expenses for eradication and herbicide treatment to stop the regeneration from the roots and in the end the 3-4 years old stems does not possess enough volume to be used for timber.

Spacing : The planting scheme with 4х4, 5х5 meters or 5х4 m between the trees which means 500 or 600 trees per hectare.
