有机基质在中国蔬菜育苗中的应用研究

研究可替代草炭的有机育苗基质具有重要的意义，并已成为研究的热点。中国研究的新型育苗有机基质原料的来源主要集中在农林有机废弃物、畜牧业工业废弃物和城市污泥等。为了更好的挖掘和利用各种有机基质资源，总结了不同原料来源的有机基质在中国蔬菜育苗中的应用情况。结果表明采用各种传统或先进技术制成的有机基质具有性状稳定、缓冲性强、营养全面、具备良好的根系生长环境等特点，有利于降低生产成本、培育优质壮苗和资源的循环利用，可以替代或者部分替代草炭育苗基质。并对今后的研究方向提出了展望，以期为中国蔬菜有机基质育苗技术的研究和发展提供借鉴。

Organic Substrate Application in Vegetable Seedling Raising in China

To study the organic substrates substitution for turf has certain significances and has become a hot research topic. The sources of organic substrates mainly concentrate in organic waste of agriculture and forestry, animal husbandry industrial wastes and municipal sludge and so on in China. In order to better explore and utilize organic substrates resources, the authors summed up the application of organic substrates of different sources to vegetable seedling raising. The results showed that the organic substrate produced by traditional and advanced technology had the characteristics of stability, strong buffer capacity, comprehensive nutrition and a good environment for root growth, which could reduce the production cost, cultivate high quality seedling and benefit cyclic utilization of resources, and replace or partly replace the turf. The prospects for future research direction were discussed to provide references for research and development on organic vegetable seedling raising technology in China.
