文摘
A decentralized seedling production is regarded as the most effective means of providing smallholders with planting materials. However, the sustainability of smallholder nursery operation is constrained by several factors, including the limited availability of germplasm, lack of technical skills and low seedling demand low viability of seedling market. The government nursery sector could complement the weaknesses of the smallholder nursery group but government nurseries are not operating effectively to enhance the availability of high quality seedlings of a wide species base for smallholder forestry. Seedling production in government nurseries is quantity-orientated with low emphasis on the production of high quality planting materials. Germplasm used in seedling production is mostly collected from unselected sources and seedlings produced are mostly of low physical quality. The species selection in government nurseries is heavily based on the availability of germplasm which resulted in the production of a few species which are commonly raised on private nurseries. The duplication of species of most seedlings raised in government nurseries with those produced in private nurseries and the far distance of government nurseries from the villages has resulted in low uptake of seedlings by smallholder tree farmers. For the government nursery sector to become more effective in providing support in the present paradigm of decentralized seeding production, a change from its production system and a broadening of the role it plays is needed. The social mobilization on seedling production as a scheme of implementing the Green Philippines Program has led the Department of Environment and Natural Resources to acknowledge the seedling production activity of private individual and communal nursery groups. This can be an opportunity for organizing the private and government nursery sectors to promote the operational effectiveness of the overall forest nursery industry.
