Abstract: Substrate block seedling, also known as nutrient block seedling, has become the predominant research direction aiming at expanding vegetable seedling and transplanting owing to advantages such as short seedling period, high survival rate, and high mechanical transplanting efficiency. This paper summarized the key technology of substrate block seedling transplanting, and described the development status, characteristics and application of substrate block seedling raising equipment and transplanting equipment in China and abroad. Taking broccoli as an example, this paper analyzed the economic benefits and application prospects of substrate block seedling raising and transplanting. The issues of substrate block seedling transplanting were analyzed, such is seedling blocks plates were too heavy to carry, blocks were boned due to no barrier between blocks, and low automaticity. And optimizing physical and chemical parameters of substrate block seedling, improving structure of substrate block seedling plate, collecting block seedling automatically to realize transplant automatically were proposed. This provides reference for the research of substrate block seedling raising equipment and transplanting equipment.
