The invention discloses a method for promoting red paeony root seed sprouting and application of the method in red paeony root propagation. The method comprises the following steps: (1) soaking red paeony root seeds in a gibberellin solution; (2) after the step (1) is finished, taking the soaked seeds, and burying the soaked seeds with sand; (3) after the step (2) is finished, taking rooted seeds, sowing the rooted seeds, and culturing the rooted seeds till the rooted seeds sprout, wherein the gibberellin solution is sprayed on the rooted seeds during the culture process. The method has the advantages that the dormancy of the red paeony root seeds is broken down effectively, so as to promote seed sprouting; the red paeony root seeds can sprout fast, the sprouting time is greatly shortened, and the sprouting rate is improved; the operation is simple, the cost is low, and the method can be widely applied to field production. The method is highly remarkable in promoting seedling raising and propagation of red paeony root, thereby having a huge economic benefit when being applied to the red paeony root industry.

The invention discloses a tomato seed treatment method which comprises the following steps of: (1) seed priming: fully mixing seeds, priming substrates and water proportionally, putting the mixture into a closed container, and standing for 5-10 days at 10-20 DEG C; and (2) crusting and coating the seeds after priming, wherein the weight of each seed is increased by 50-200% after coating. The tomato seeds processed by utilizing the method disclosed by the invention have the characteristics of high germinability, high rate of emergence and strong stress resistance, and are convenient for seeding; and the method is suitable for precise seeding of the tomato seeds.

The invention discloses a technology for culturing the seed of short-pedicel aconite root, which comprises the steps of: preparing a seed bed, seeding, managing the seed culture and outplanting. The technology is characterized in that the seed is sprouted before seeding, is immersed with water of 55-60 DEG C for 24-36 hours, and is taken out and put into a seal plastic seed bag to be sealed; the seed bag is put into a thermostatic culturing room of 20-25 DEG C for 36-48 hours; and the seed can be taken out once becoming white to seed. The technology can shorten the seed emergence time of the short-pedicel aconite root by 15-20 days, improves the seed emergence ratio by 25-30%, obviously reduces the seed culturing cost and improves the quality of the seed.
