The Study on Technology Development System of Fuel Forest Resources in the North China

This paper reports a research result of technology development system of fuel forest resources at the places where are both lower level hills and arid areas. Retaining the natural precipitation with the special filling and soil preparation technologies, the survival rate of afforestation on barren mountains can reach 93.4%. Adopting an artificial promotion technology and brushwood production method to transform low output locust trees, the quantity of overground organisms can increase 21.5% and 69.1% respectively. Transforming Chinese pine forest on a hill into the mixed forest, the annual forest output can be obtained 190 kg/mu Planting mixedly sallow thorns, a nitrogen-fixing bush, among the rows of poplars on the flood land, the annual forest output can be obtained 325 kg / mu. Topdressing phosphate fertilizer, the organic quantity of three-year locust can increase 29.8%. Using an artificial inoculation against nodule bacteria or both of nodule bacteria and vaccine, the organic quantity of young locust can increase 29.8～48.6%.
