Eustoma grandiflorum seed composite initiator and preparation method thereof

Abstract

The invention discloses a eustoma grandiflorum seed composite initiator and a preparation method thereof. The eustoma grandiflorum seed composite initiator comprises the following components: 50-200g / L of polyethylene glycol, 10-30g / L of mannitol, 0.1-0.3 g / L of salicylic acid, 0.1-0.3 g / L of gibberellin and 1-3g / L of chitosan. The preparation method comprises the following steps: adding 50-200g / Lof polyethylene glycol into water until polyethylene glycol is completely dissolved, adding 10-30g / L of mannitol until mannitol is completely dissolved, adding 0.1-0.3 g / L of salicylic acid, stirringthe solution until salicylic acid is completely dissolved, then adding 0.1-0.3 g / L of gibberellin, stirring the solution until gibberellin is completely dissolved, adding 1-3g / L of chitosan, and stirring the solution until chitosan is completely dissolved. The seed coating agent can improve the germination capacity of seeds and promote seed germination and seedling growth, and is easy to degrade,non-toxic and harmless.

Description

technical field [0001] The invention belongs to the field of planting technology, and in particular relates to a compound initiator for eustoma seeds, and also relates to a preparation method of the compound initiator for eustoma seeds. Background technique [0002] Seed priming refers to a pre-sowing seed treatment technology that allows the seeds to slowly absorb water and gradually dry out under certain treatments, thereby making physiological preparations for germination in advance. The principle is to soak the seeds in a high-osmosis solution. By controlling the water absorption process of the seeds, the seeds slowly absorb water and the seeds are in the stage II of oxygen and water absorption. The metabolism of growth substances, and when the seeds germinate again, the transition time from stage II to stage III will be advanced, so that the seeds can get a good germination effect. At present, seed priming technology has been successfully applied to many plant species,...

AI Technical Summary

Problems solved by technology

However, different plant seeds have different effects on the type and concentration of the initiator, and sometimes even have a negative effect. Therefore, it is urgent to screen an initiator that can significantly improve the priming effect of eustoma seeds and apply it to the production of eustoma.
