摘　　要：为提高农业废弃物的资源化利用率,以稻壳和黄泥为辅料与西兰花加工废弃物堆肥混合发酵,堆肥与黄泥按不同质量比制成4种基质,研究其对水稻秧苗素质及产量的影响,探索西兰花废弃物基质化应用的可行性。结果表明,水稻秧苗素质、秧苗干物质积累、产量等指标随着基质中堆肥占比的提高均呈现先升高后降低趋势,其中黄泥与堆肥质量比为1:1时育秧效果最好,出苗率、整齐度、根冠比和壮苗指数分别为84.00%、85.15%、38.00%和0.94,水稻产量为7299.85kg/hm^(2),且与常规基质处理无显著差异;通过建立回归方程进一步预测,当黄泥与堆肥质量比为0.87:1时育秧效果最好。西兰花废弃物堆肥配制的基质基本可以达到常规基质的育秧效果,对于实现低污染、低排放的“西兰花—水稻”循环农业生产模式具有十分重要的意义。In order to improve the resource utilization rate of agricultural waste,rice husk and yellow mud were mixed with broccoli processing waste for fermentation,the compost and yellow mud were made into four kinds of substrates according to different mass ratios.The rice seedling quality and yield were studied to explore the feasibility of substrate application of broccoli waste.The results showed that the quality of rice seedlings,dry matter accumulation of seedlings,yield and other indicators increased first and then decreased with the increase of the proportion of compost in the matrix.When the mass ratio of yellow mud to compost was 1:1,the seedling raising effect was the best.The emergence rate,uniformity,root-shoot ratio and strong seedling index were 84.00%,85.15%,38.00%and 0.94,respectively.The rice yield was 7299.85kg/ha,and there was no significant difference compared with the conventional matrix treatment.It was predicted by establishing the regression equation that when the mass ratio of yellow mud to compost was 0.87:1,the seedling raising effect was the best.The substrate prepared by broccoli waste compost could basically achieve the seedling effect of conventional substrate,which was of great significance for the realization of low pollution and low emissionʻbroccoli-riceʼcircular agricultural production mode.
