Intensive large timber forest farming using new acacia varieties

Quang Tri is implementing agricultural extension programs and projects to accelerate the introduction of new acacia hybrid for tissue culture, acacia mangium varieties into large timber plantations.

In the North Central region, in recent years, thanks to efforts in afforestation and development of forestry production, the area's forest average cover reached 57%, higher than the national average, contributing to climate stability.

For the purpose of synchronously transferring and applying technical measures for afforestation with large timber intensive farming by using new varieties with high yield and climate change adaptation, supported by the National Agricultural Extension Center. According to experts, the Agricultural Extension Center of Quang Tri province is initiating the Project of building and developing a model of intensive afforestation of large timbers of acacia hybrid and acacia mangium in 4 central provinces including Ha Tinh, Quang Binh, Quang Tri, Thua Thien - Hue from 2019 to 2021.

The implementation of the project will build several demonstration sites for large timber plantations meeting the demand for sawn timber to replace natural forest wood, help forest growers build confidence when they want to convert plans from production areas to study tours. The objective is to improve the productivity and quality of planted forests by over 30% compared to mass plantations and the economic efficiency is 1.5 - 2 times higher than that of small timber plantations.

Mr. Phan Ngoc Dong, Deputy Director of Quang Tri Agricultural Extension Center, shared that the project, after 2 years of implementation, has received a positive response from the participants, the initial results are very good. The people are very excited and believe in the success as the project's goals portrait

The program has been deployed with the initial result in 2019 is 120 ha of acacia hybrid, in particular: Quang Tri 40 ha, Ha Tinh 30 ha, Quang Binh 30 ha, Thua Thien - Hue 20 ha; In 2020: 130 ha of Acacia Tai Tuong, of which: Quang Tri 40 ha, Ha Tinh 30 ha, Quang Binh 30 ha, Thua Thien - Hue 30 ha. In parallel with the implementation of models, the project has conducted training activities on afforestation in the first year, care, management and protection of forests in the following years.

According to the plan with a 10-year business cycle, the acacia hybrid sawn timber forest will achieve a timber volume of 180 m3/ha, earning VND 191.5 million/ha/10-year forest business cycle with 60% sawn timber products and 40% wood chips. The calculated profit will be VND175.2 million/ha, VND 17.52 million/ha each year, 2-3 times higher than small wood hybrid cultivation with a 5-year business cycle in terms of economic efficiency.

"In the coming time, the Agriculture and Rural Development sector will advise the People's Council and People's Committee of the province to issue policies on the application of tissue-cultured acacia hybrids in large-scale timber intensive production afforestation. We hope to increase 500 ha of this forest per year to promote the forestry transformation towards high quality and productivity, creating a raw material area that will provide uniform wood products for the deep processing of wood products, fully making use of the value of each forest type, increasing the production value per unit area.
