用食用菌渣等废料配制新型蔬菜育苗基质的研究

Studies on Making up New Vegetable Seeding Substrates Using Edible Fungus Slag and Other Wastes

为配制出适宜于蔬菜穴盘育苗的廉价基质,替代草炭等昂贵材料,本研究以食用菌渣、腐叶、炉渣等工农业废料为原材料,配制出了一系列基质,并从总孔隙度、通气孔隙度、持水孔隙度、大小孔隙度比、容重、pH、酸碱缓冲能力、N、P、K和有机质的含量以及育苗实验观察等几个方面对所配基质进行了考察和筛选,最终选择出3组性能优良,适宜于推广的基质配方。为蔬菜育苗产业的发展提供一定的参考。

In order to make up low-priced substrates that is suitable for vegetables seeding in hole tray and replace turf and other expensive materials, edible fungus slag, decay leaf, slag and other industrial and agricul- tural wastes were used as raw material in this experiment. A series of substrates were made up and they were in- vestigated and screened from such aspects as the total porosity, ventilation porosity, hold water porosity, size porosity ratio, bulk density, pH, acid-base buffering capacity, N, P, K and organic matter content and seeding ex- periment, etc. Finally, three groups with excellent performance were selected. They were suitable for being popu- larized. This study provided certain reference for the development of industry of vegetable seeding.
