The invention relates to a crystal seed stability detection method and detection system. The crystal seed stability detection method comprises the following steps: respectively measuring and calculating the stability of crystal seed systems at different time points in the aging process; mixing the crystal seed systems at different time points in the aging process with diluent, and detecting by using a turbidity meter so as to obtain turbidities of different time points; establishing a relationship table of the turbidities and the stability; preparing a crystal seed diluted liquid under same conditions of the crystal seed system and the diluent in the former aging process, performing on-line detection by using the turbidity meter so as to obtain an instant turbidity, and comparing according to the relationship table of the turbidities and the stability, thereby obtaining instant stability. The detection device comprises a container, a mixing device, the turbidity meter and the like applicable to the method. According to the detection method, as the corresponding relationship table of the turbidities and the stability is firstly established, the stability can be calculated according to the turbidities according to the relationship table, and thus the detection accuracy and the instantaneity can be remarkably improved.

The invention discloses a method for making artificial seeds of red maple, belonging to the technical field of artificial seeds. The production method involved in the present invention firstly puts the sterile Chinese red maple somatic embryos into the artificial endosperm on the ultra-clean workbench, mixes them evenly, and then sucks one propagule at a time with a straw and drops it into the artificial seed coat After ion exchange reaction for 15min, rinse with sterile water for 20min, terminate the reaction, pick up and dry to get red maple artificial seeds, and finally, use the transplanting substrate to transplant and refine the seedlings, keep the substrate moist, and the air humidity is 70% to 90% , spray water 4 to 5 times a day, and carry out indoor hardening and transplanting. The red maple artificial seed system prepared by the invention has good stability, is relatively simple to manufacture, and has a high seedling emergence rate. At the same time, Chinese red maple somatic embryos are used as propagules, and the resources used are novel.

The invention discloses a self-adaptive seeding control system based on an unmanned driving technology.
