Abstract

To meet the growing shortages of industrial wood, large scale plantations of poplars have been raised in the country. Poplar wood possesses high timber and fibre value for industrial applications. Several studies on different utilization aspects of Poplar, including its physical and mechanical properties, wood working and carving quality, and its suitability for plywood, hardboard, particle board and laminated wood etc., have been undertaken. The wood is now extensively used in the manufacture of plywood, match boxes and packing cases etc. With increasing availability of Poplar wood in coming years, it is necessary to study in detail clone-wise properties and utilization of Poplar species for diversifying the use of Poplar wood. This paper describes the recent research and development work carried out on Poplar wood utilization for reconstituted wood products at this Institute.

Abstract

Among the exotics, Eucalyptus has emerged as the most favoured species under afforestation programmes in most of the countries where it has been introduced for obtaining higher biomass productivity. However, ischolar_main feeding tel mitts have proved a major constraint for its successful propagation both in nurseries and plantations. Localised tumite damage bas been estimated to result in 50-80 per cent mortality in seedlings and young plantations in some localities. Till recently, the recommendations have been based on bigbly persistent cblorinattd hydrocarbon insecticides, most of which have been banned and are not easily available. In our experiments on the comparative efficacy of various insecticides, chlorpyrifos an organophosphate compound has been found an equally effective insecticide for soil treatment. In the present study, an attfmpt has been made to evaluate various methods of application and the optimum dosage requind for controlling termites in Eucalyptus.

Abstract

The Indian Council of Forestry Research and Education, Dehradun, being an umbrella organization under the Ministry, is actively engaged in forestry research and knowledge dissemination through its eight research institutes and four advanced centers all over India. The paper describes the financial assistance by ICFRE to universities, initiative for accreditation of forestry Institutions and courses, training at National and International level to the scientific/managerial cadre/research support staff under HRD Plan and participation of officers/scientists in seminars/workshop/conferences, policy on human resource development in ICFRE, gap analysis in forestry education and strategies for forestry education in India. The objectives of Forest Research Institute Deemed University (FRIDU) and recognized research centers of FRI Deemed University are also described.

Abstract

Bamboo is as a raw material found in whole over India. A number of production techniques can be used to improve the properties of MDF; particularly the tensile strength perpendicular to grain (internal bond). One of the new techniques is needle punch. Where-in the wooden frame with needles is used to punch the fibre mattress before making a board. Effect of needle punch technique on physical and mechanical properties of MDF board was evaluated. Boards were prepared from bamboo with 6%, 8% and 10% phenol formaldehyde resin using needle punch technique (two time punch) after the mat formation at three different pressure i.e., 14 kg/cm², 17.5 kg/cm² and 21 kg/cm², respectively, for 15 minute hot pressing. The physical and mechanical properties of MDF board were evaluated as per IS specification 12406:2003. An increase trend in the internal bond strength of MDF board with the increase in needle punching during mat formation as well as resin content and pressure was observed. The results indicate that suitable MDF boards can be prepared using needle punch technique (two time punch) with 10% resin content at 21kg/cm² specific pressure which meets most of the other physical and mechanical properties as per IS: 12406:2003. Some of the physical properties of board like water absorption and general swelling were higher than the Indian Standard requirements which can be controlled by suitable treatment.
