Cultivation of Paulownia - 4. Planting & Establishment

The problematic tribute to the cultivation of Paulownia seems to continue. Rumors show that the fourth in the series part, which is dedicated both to the Paulownia planting and to the successful establisment of the plantation, is ante portas.

The population is asked to stand up to the circumstances. Temperament is the point. No conciliation with the enemy.

From now on, we speak Japanese.

Preparing the Soil for Paulownia Planting & Establishment

For Paulownia planting is of decisive importance the proper preparation of the soil. Once the appropriate site has been selected, the treatment begins at the end of the summer or early autumn. First plowing is done at a depth of 1 m in order to solubilize, oxygenate and improve the soil structure. Deep plowing, in addition to other benefits, also contributes to breaking any solid soil horizons (clay and sedimentary layers).

Two to three weeks later, new, less deep plowing takes place, especially in relatively heavy soils, or milling. Another milling can be done at the beginning of winter before the young seedlings are installed.

In any case, the more soft the texture of the soil, the more the development of the root in the cultivation of Paulownia is favored.

Weed Control

The Paulownia planting will be successful, since, among other things, there is effective weed control especially in the early years. Control of weeds can be done either by chemical or mechanical means.

If chemical weed control is selected, the herbicide is applied at least 3 weeks prior to planting. The herbicides are sprayed onto a strip of 1.5 m wide, in the middle of which the planting will take place.

Herbicides should be able to control weed populations for at least 9 months.

However, for the effective control of weeds in the cultivation of Paulownia, herbicide is recommended to start early in the autumn. When the weeds are active, a foliar herbicide spray can be done, which will work in depth.

If for any reason the intervention does not take place in the early autumn then it can be done at the end of this but with a soil herbicide.

Before wearing it is advisable to predict weed mowing as this will increase the herbicide’s effectiveness. Here it is worth noting that soil herbicides should not be used early in the fall because they lose much of their efficacy.

If it is chosen not to do chemical control then milling is done to control the weeds. However, where there is a serious risk of erosion or waterlogging, the approach is different.

The method of cutting weeds with lawn mowers instead of mechanical cultivation and the planting of Paulownia seedlings at raised beds 30 cm height is chosen.

In all cases, the goal is the uninterrupted installation of Paulownia seedlings and the avoidance of nutritional competition between them and the weeds.

Paulownia Planting - Distances

The distances for the Paulownia planting are determined by the final use of the product produced, whether it is biomass or timber wood plantation.

For the production of biomass for energy use (pellets, briquettes), the planting distances are 2 m between lines and 3 m on the lines, ie 1670 trees per hectare are planted or when pure energy crops are planted, the distances are 3 x 3 m, 1110 trees per hectare.

For timber wood production, planting distances are recommended to be 3.5 x 3.5 m (820 trees / hectare), 4 x 4 m (620 trees / hectare) or 5 x 5 m (400 trees / hectare) or and 7 x 7 (about 200 trees / hectare) to produce excellent timber wood quality.

Planting Procedure

Initially, planting holes of diameter and depth of at least 30 cm are opened. They include a full fertilizer as well as compost. Then the Paulownia seedlings are planted in such a way that their neck is covered with soil at a height of 1 cm. Then press the ground so that there are no gaps between it and the roots.

In Japan, they follow a different method. The excavated planting holes are 1×1 m in size. At the depth of the holes and up to 30 cm they add the surface soil, which is strong and fertile. Then drop a layer of compost about 10 centimeters thick. Finally they cover the pit with good quality soil.

And since the Japanese make their owns, the Cultivation of Paulownia will also make its owns to. The Japanese Yossida Brothers have the musical speech.
