Description

Technical Field

[0001] This invention relates to the field of agricultural biotechnology, specifically to a high-efficiency propagation system and method for sweet bamboo seedlings. Background Technology

[0002] Sweet bamboo is a large, clumping bamboo species with high economic value. Its shoots are white, fleshy, and have a sweet, non-astringent taste, earning it the reputation of "King of Bamboo Shoots" and making it a high-quality forest vegetable.

[0003] In addition, the sweet bamboo has straight and high-quality bamboo, which can be used in construction, papermaking and handicrafts. In recent years, with the increasing market demand for high-quality bamboo shoots and ecological materials, the large-scale planting industry of sweet bamboo has developed rapidly.

[0004] However, traditional methods of propagating sweet bamboo seedlings are inefficient, mainly relying on division and transplanting. This method has an extremely low propagation coefficient (usually only a few times the growth per year) and will seriously damage the mother plant, which cannot meet the huge demand for high-quality seedlings in large-scale, intensive planting. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a high-efficiency propagation system and method for sweet bamboo seedlings that is easy to promote and ensures production capacity and cultivation quality.

The mother bamboo cultivation unit is planted with sweet bamboo mother plants that have undergone shoot removal treatment, and is equipped with root fixing supports and drip irrigation interfaces; The rapid propagation treatment unit is set up adjacent to the mother bamboo cultivation unit to disinfect, promote sprouting and induce rooting of explants obtained from the mother bamboo. The multi-layered seedling cultivation unit receives the seedling materials processed by the rapid propagation unit and cultivates them on a large scale in a three-dimensional space. The transplanting and transportation unit transports the seedlings between each unit and when they leave the nursery. The control center controls the environmental parameters and operational procedures throughout the entire seedling propagation process.

[0007] Preferably, the temperature-controlled greenhouse is also equipped with a nutrient supply module and a multi-zone environmental dynamic control module. The nutrient supply module includes a nutrient solution preparation tank, a delivery pipeline network, and a precision irrigation terminal set at each cultivation unit, providing customized water and fertilizer supply to the mother bamboo cultivation unit, the rapid propagation treatment unit, and the multi-layer seedling cultivation unit respectively. The multi-regional environmental dynamic control module includes a sensor group and a control actuator set in different zones.

The control actuator independently and precisely controls the environment of each zone according to the instructions of the control center.

[0008] Preferably, the rapid breeding processing unit includes a pretreatment station, a hormone treatment station, and a dark culture station arranged sequentially. The pretreatment station is equipped with a cleaning tank and a disinfectant spraying device to perform surface cleaning and sterilization on the explants.

[0009] Preferably, the multi-layer seedling cultivation unit includes three or more vertically stacked cultivation racks, each layer is covered with a breathable seedling tray, the bottom is provided with a liquid return collection tank, the top is equipped with an adjustable LED plant growth light, and the side wall is integrated with a micro-mist nozzle.

[0010] Preferably, the transplanting and transporting unit includes a track laid on the ground and a lifting and transporting robot that moves on the track; The lifting and transporting robot automatically picks up and places seedling trays between different units.

[0011] Preferably, the customized water and fertilizer supply in the nutrient supply module includes: High-nitrogen nutrient solution for mother bamboo cultivation units; Root-promoting solution for rapid propagation treatment units; Nutrient solution for strengthening seedlings used in multi-layer seedling cultivation units.

[0012] Preferably, the control center also integrates a sweet bamboo seedling growth model database; The database of the sweet bamboo seedling growth model includes expert experience data, web crawler data, and shared experimental demonstration data.

[0013] Another aspect of this invention discloses a method for using a high-efficiency propagation system for sweet bamboo seedlings, comprising the following steps: S1: Select 2-3 year old, disease-free sweet bamboo mother plants, remove the tops and plant them in the mother bamboo cultivation area, keep the root system fixed and regularly supply high nitrogen nutrient solution to promote tillering. S2: New tillers or segments are collected from the base of the mother plant as explants and sent to the pretreatment station for rinsing with clean water and spraying with disinfectant to sterilize. S3: Immerse the sterilized explant base in the soaking tank, and then transfer it to the dark culture station for light-proof culture to induce the formation of adventitious root primordia; S4: Transfer and transplant into the breathable seedling trays of the multi-layer seedling cultivation unit; S5: After 15-25 days of hardening off, when the seedlings reach a height of 25-35 cm and have more than 3 unfolded leaves, they are ready to be transplanted.

[0014] Preferably, step S4 further includes using agricultural supplemental lighting for dynamic lighting, intermittent spraying for moisture retention, and supplying a balanced seedling nutrient solution. The control parameters are supplied by matching the seedling growth model database.

[0015] The advantages of this invention compared to existing technologies are as follows: It employs a customized water and fertilizer strategy, supplying high-nitrogen solution, root-promoting solution, and seedling-strengthening solution at different stages to improve rooting and seedling hardening quality; the multi-layered, three-dimensional cultivation and automated transport design improve space utilization and operational efficiency.
