CULTIVATION TECHNIQUES OF GMELINA ARBOREA

  • Received Date: 1989-06-28
  • A cultivation technique of Gmelina arborea is reported in this paper. The suitable growing area for G. arborea is to the south of 23 癗, where the annual mean temperature is 20.5-24.5℃, extreme low temperature higher than -1.5℃, annual rainfall 1200~2 000mm, annual wind-speed less than 2.5m/s. The suitable site for planting is that of open ground, full of sunshine, loose soil, epipedon organic matter more than 2%, total nitrogen more than 0.1%, available phosphate more than 0.25mg/100g soil, pH value 4.5-6.9, and the soil moisture content is 10%~24%. Seed storage in the desiccator has a best effect, its germination rate is up to 87.4% after storing for one year. Hastening germination of seed with soaking and drying repeatedly or soaking in lime-water for seven days can help to germinate earlier for 10 days and increase 9%~12% of germination rate comparing those of the checks. Bud-seedlings with different types of cotyledon transplanted individually can enhance over 20.6% of the seedling qualified rate than those of mixed transplanting. Besides, the main quality index and the methods of seedling nursing and planting with best effect had been evaluated in this paper. The comprehensive index of cultivation technique is that the mean annual increment in volume is 12m3 per ha.

Abstract: A cultivation technique of Gmelina arborea is reported in this paper. The suitable growing area for G. arborea is to the south of 23 癗, where the annual mean temperature is 20.5-24.5℃, extreme low temperature higher than -1.5℃, annual rainfall 1200~2 000mm, annual wind-speed less than 2.5m/s. The suitable site for planting is that of open ground, full of sunshine, loose soil, epipedon organic matter more than 2%, total nitrogen more than 0.1%, available phosphate more than 0.25mg/100g soil, pH value 4.5-6.9, and the soil moisture content is 10%~24%. Seed storage in the desiccator has a best effect, its germination rate is up to 87.4% after storing for one year. Hastening germination of seed with soaking and drying repeatedly or soaking in lime-water for seven days can help to germinate earlier for 10 days and increase 9%~12% of germination rate comparing those of the checks. Bud-seedlings with different types of cotyledon transplanted individually can enhance over 20.6% of the seedling qualified rate than those of mixed transplanting. Besides, the main quality index and the methods of seedling nursing and planting with best effect had been evaluated in this paper. The comprehensive index of cultivation technique is that the mean annual increment in volume is 12m3 per ha.
