Through the state agricultural extension project “Developing a model of intensive afforestation of large-timber Acaia auriculiformis” chaired by Vietnam Academy of Forestry Sciences (VAFS) and the Forest Science Center of North Central Vietnam (FSCV) as a unit to coordinate implementation at 02 Quang Tri and Quang Ngai provinces, identifying the role as the important connertor in researching and transferring of science and technology to famers and local extension officers of the two provinces; In 3 years (2017-2019) FSCV has actively cooperated with stakeholders to successfully develop 160ha large timber Acaia auriculiformis model, organized 18 technical trainings for 460 participants and 8 workshop for 160 people, contributing to the realization of the common goal of the Forest Sector Restructuring Project, and will be a demonstration model of economic afforestation towards intensive farming, using new varieties which recognized as a basis for developing raw material areas for the wood processing industry.

Mrs. Nguyen Thi Lieu – Chair woman of branch project introduced the project to famers in Cam Nghia Commune – Cam Lo – Quang Tri.

In the past years, with the support of capital from projects such as PAM, 327, 661, etc., people in the two provinces of Quang Ngai and Quang Tri have developed acacia tree plantations. According to local people, the Acacia auriculiformis can well adapt to the dry condition of the area; This tree is more resistant to wind and storms than Acacia hybrid and Acacia mangium, good wood can be used for sawn timber, etc. However, because the seed source has not been selected and applied technical advances in silviculture is still limited, so the tree grows very slowly, takes a long time to harvest and the quality of the tree is low. Therefore, there is not much area of Acacia acacia plantation in the two provinces.

The development of varieties selection and sylvicutural techniques has contribute significantly to improving productivity and quality of plants. With the efford of the scientists from VAFS, many varieties of Acacia auriculiformis such as AA1; AA9 (QĐ3905/QĐ-BNN-KHCN dated 11/12/2007); CLT 26; CLT 7; CLT 98; CLT 18 (QĐ2763/QĐ-BNN-LN dated 1/10/2009) provide high productivity and resistance to pests and diseases; These varieties are also higher in adverse environmental conditions than the old varieties. The intensive afforestation by the use of fertilizers, planting density, thinning techniques, trunk thinning, leaving materials after harvesting, etc. are also new advances that have not yet been widely disseminated in production for the people of Quang Ngai and Quang Tri.

From that meaning, the transferring of technical advances on variesties and sylviculture of intensive afforestation of large-timber Acaia auriculiformis was implemented by different methods including: training, developing demonstration site model, conferences, technology transfer, encouraging technical innovation, visting demonstration model, etc … These methods have contributed significantly to improving the mind-set, awareness, production level for famers and extension officers of the two provinces.

FSCV has effectively transfer the techniques of intensive afforestation of large-timber Acaia auriculiformis; the famers have received the advance techniques more profitable, even 75% of them were ethnic minorities. Especially when building 160ha model/160 households, farmers can self-deploy and apply right on their own land; After 3 years of applying new techniques, through the assessment of the related sectors, the deployment models ensure on schedule, bringing practical effects to farmers with a survival rate of 90% or more of planted forests. ; plantation productivity reached 20 m3/ha/year, an increase of 20% compared to the model of using varieties and mass-intensive farming

Participants visited the large-timber model of FSCV at Cam Hieu – Cam Lo – QuangTri

In the coming time, FSCV will continue to encourage famers and local people applying scientific and technical advances to production, put into trial and replicate new varieties with high productivity and quality. Focus more on consultancy activities to famers on afforestation in the direction of economic – social – environmental sustainability…
