规模化培育机插秧必须使用育秧基质。目前生产上普遍采用的商品有机基质，能培育出素质较好的秧苗，但成本过高，制约了机插秧的大面积推广。笔者通过试验探索了红黄土谷壳混配基质规模化培育机插秧新技术，与高质量的有机商品基质育秧相比，红黄土谷壳混配基质亦可培育出同等质量的机插秧苗，并显著降低成本，适合工厂化、规模化培育机插秧。

The seedling matrix must be used in the large-scale transplanting machine. At present, the commercial organic matrix widely used in production could produce better quality seedlings, but the cost was too high, restricted the machine transplanting rice to spread widely. After several years of exploration and practice, a new matrix of red loess mixed with rice husks was developed. Compared with the commercial organic matrix widely used in production, the same quality rice seedlings can be produced by the matrix of red loess mixed with rice husks, and significantly reduced costs. It is suitable for large-scale and machine transplanting seedling raising in factories.
