Solid triggering method for raising seed actirity

Abstract

A solid triggering method for increasing the activity of seeds includes metering the weight of the seeds to be treated, preparing clean sand, regulating the water content of sand to 1-9%, proportionally mixing said seeds with said sand, staying in closed container at 15-25 deg.C for 2-5 days, and drying at ordinary temp for 24-48 hr. Its advantages are high effect, and low cost.

Description

technical field [0001] The invention relates to seed treatment and seed physiological application technology, in particular to a solid initiation method for improving seed vigor. Background technique [0002] Seed priming can improve seed vigor, accelerate seed germination ability under adversity (such as low temperature, high temperature, water deficiency, salinity or low oxygen, etc.), improve germination consistency, emergence rate, emergence rate and seedling rate. Regarding seed priming, it has been reported on many plant species, such as food crops, vegetable crops, ornamental plants and so on. In rice, Qin Hong and Zheng Guanghua (1994) used polyethylene glycol (PEG) to induce the vigor of hybrid rice seeds, and at the same time effectively reduce the imbibition and chilling damage of rice seeds. Ruan Songlin (2001) used -1.25MPa PEG to increase the emergence rate and seedling rate of rice seeds in flooded soil. Priming also increases the v...

Problems solved by technology

[0003] Conventional priming methods are not suitable for application in field crops. For example, PEG priming costs are high, and it is currently limited to some vegetable seeds in production. Roller priming requires certain mechanical equipment (Rowse, 1996), and only a small amount of seeds can be processed each time. , not suitable for field production requirements

Solid substrates such as vermiculite are mostly limited to laboratory experiments due to the difficulty of obtaining materials, and have not been applied in production.
