摘要
为了促进水稻工厂化育苗正常成熟、高产稳产,以秸秆和食用菌渣等多种农业废弃物为试验材料,对寒地水稻育苗专用基质配方进行了研究。结果表明:分别以稻壳、粉碎秸秆、食用菌渣为主要原料配制的3个基质处理与对照相比都有明显效果,秧苗素质指标中根数和地下部鲜重与CK有显著差异,产量性状中除穴数外其它指标都有显著差异,而处理间差异不明显,充分说明育苗基质完全可以替代床土与寒地水稻三化栽培技术配套使用,达到壮苗标准。
In order to promote normal mature,high and stable yield of rice industrialized seedling production.Taking agricultural waste（straw and residue of edible fungi,and so on）as experimental material,the substrate formula of rice industrialized seedling production in cold region was analyzed.The results showed that with rice husk,comminuted straw and residue of edible fungi as the main raw material,compounding 3substrate treatments compared with the CK have obvious effect,there is significant difference in root number and root fresh weight of seedling quality index with the CK,in addition to the den number characters other yield indicators have a significant difference,it fully shows that the substrate could completely replace the bed soil and rice cultivation technique＂rice field standardization,rice seedling medelling,management index planification＂,reach the healthy standard.
