AI Technical Summary

Technical Problem

Existing seedling cultivation techniques suffer from insufficient precision in environmental control, low nutrient solution recycling rate, low facility space utilization rate, and fragmentation of various stages, making it difficult to meet the differentiated needs of different growth stages. In particular, plants with high lignin content have difficulty rooting and have low survival rates.

Method used

By employing a method of zoned collaborative operation, intelligent environmental control, and closed-loop nutrient circulation, and through phased parameter adjustment and substrate structure design in the pretreatment zone, rapid propagation zone, and hardening zone, combined with a PLC control system and closed-loop nutrient solution circulation, precise control of light, nutrient solution EC value, and pH value is achieved. Activated carbon is used to adsorb phenolic inhibitors, and the carbon-nitrogen ratio and hormone addition are optimized.

Benefits of technology

It significantly improves seedling efficiency and survival rate, especially the propagation efficiency of lignified plants, achieving efficient rooting and seedling formation, and is suitable for large-scale commercial seedling production.

Abstract

The invention discloses a rapid seedling raising method and system for field tissue culture. Efficient seedling raising is achieved through partition collaborative operation, intelligent environment dynamic regulation and control and closed-loop nutrition circulation. The method comprises the following steps: carrying out ultraviolet disinfection and material cutting in a pretreatment area, regulating and controlling an aerial fog root promoting environment in a rapid propagation area, and carrying out gradual transition in a seedling hardening area; adjusting the illumination intensity, the nutrient solution EC value and the hormone ratio in stages; a 75 # main pipe and a return pipe form a closed circulating system. The special seedling culture tank is provided with a cobblestone-perlite layered structure and is matched with an activated carbon adsorption technology, so that the rooting rate of the lignified branches is remarkably increased. The system integrates PLC intelligent control, a multi-layer three-dimensional cultivation frame and an adjustable shading device, and automatic management of the seedling raising process is achieved. The method greatly shortens the seedling period, improves the survival rate and the breeding efficiency, and is suitable for large-scale production of various commercial crops.
