摘要： 为提高机插秧育苗基质的秧苗素质和使用效果，本研究以常规机插秧育苗基质柴米河基质为研究材料，通过不同方式添加机插秧育苗专用肥育苗伴侣，研究对基质育苗秧苗素质的影响。结果表明：使用育苗伴侣培肥机插秧育苗基质，其株高、叶龄、茎基宽、单株叶面积、SPAD值、根体积、百苗干重、壮苗指数等秧苗素质均显著提高；基质中碱解氮、速效磷含量显著提高，并提高了秧苗体内可溶性蛋白质含量，增加了GS、GPT、GOT、SOD等酶活性；移栽大田后，增产显著。其中，将育苗伴侣与基质拌和、施用于盘下苗床上效果更佳。通过育苗伴侣培肥基质，是解决目前基质易脱肥落黄、秧苗素质不稳定的有效途径，育苗伴侣使用越早效果越好。

Abstract: In order to improve the seedling quality and the effect of seedling substrate on machine-transplanted rice, the conventional seedling substrate Chaimihe was used as the material, added with the special seedling fertilizer Yumiaobanlv in different ways, to study the influence of substrates on seedling quality. The results showed that the seedling quality was improved significantly along with the fertilization containing Yumiaobanlv, including the plant height, the leaf age, the base stem width, the leaf area per plant, the value of SPAD, the root volume, the dry weight per hundred seedlings, the strong seedling index and so on. The contents of the available nitrogen and the rapidly available phosphorus increased significantly in the substrates, and the content of soluble protein in the seedling body was improved, and the enzyme activities of GS, GPT, GOT and SOD were also increased. The yield of machine-transplanted rice increased significantly after transplanting to field. The effects of mixing Yumiaobanlv with the substrates and sowing Yumiaobanlv between plate and seedbed were much better than that of other fertilization methods. Yumiaobanlv mixed with the substrates was an effective measure to solve the problems such as the deficiency of nitrogen and the instability of seedling quality. The sooner Yumiaobanlv was used, the better the effect was.
