Problems solved by technology

Existing priming technology is not suitable for above-mentioned priming treatment of grass flower seeds, such as sand priming is not suitable for processing micrograss grass seeds, solution immersion priming method is not suitable for processing seeds with mucus on the surface such as pansies, because the mucus layer expands after absorbing water, which affects the gas flow. exchange, thereby affecting the pregermination of the seeds

Embodiment 1

[0013] Weigh 10 grams of selected pansy seeds, dissolve 295 grams of PEG 20000 in 1 kg of water, configure a solution with an osmotic potential of -1.0Mpa, then pour it into a container with a diameter of 40cm and a height of 1cm, and then add it to the solution Put a semi-permeable membrane with a diameter of 40cm on it, place 10 grams of pansy seeds evenly on it, cover it, and place it for 14 days at 10°C. After priming, take out the seeds and place them in a drying oven at 25°C to dry to a safe water content, then seal them for storage or store them at 4°C within a week for sowing.

Embodiment 2

[0015] Weigh 1 gram of selected petunia seeds, dissolve 366 grams of PEG 20000 in 1 kg of water, configure a solution with an osmotic potential of -1.5Mpa, then pour it into a container with a diameter of 30cm and a height of 1cm, and then add it to the solution Place a semi-permeable membrane with a diameter of 30 cm on it, place 1 gram of petunia seeds evenly on it, cover it, and place it at 15°C for 12 days. After initiation, the seeds were taken out and placed in a drying oven at 25°C for drying or directly for subsequent pelletization treatment.

Embodiment 3

[0017] Weigh 10 grams of selected bunches of red seeds, dissolve 431 grams of PEG 20000 in 1 kg of water, configure a solution with an osmotic potential of -2.0Mpa, then pour it into a container with a diameter of 50cm and a height of 1cm, and then add it to the solution Put a semi-permeable membrane with a diameter of 50cm on it, place 10 grams of pansy and a bunch of red seeds evenly on it, cover the lid, and place it at 20°C for 7 days. After priming, the seeds were taken out and stored at 4°C to complete the sowing within two weeks.

Abstract

The invention discloses a herbaceous flower seed priming method. The method comprises the following steps: 1) carefully selecting seeds; 2) preparing a polyethylene glycol solution with an osmotic potential being between -0.5 and -2.0 Mpa; 3) pouring a PEG solution into a container, putting a semi-permeable membrane with a same size on the solution, putting the seeds to be treated on the semi-permeable membrane, allowing the container to stand at 10 DEG C-20 DEG C for 7-14 days; 4) drying at 25 DEG C for 24 hours, or directly sowing without drying. The invention adopts a semi-permeable membrane to control the water absorption process of the seeds, avoids direct contact of the seeds with the solution, is applicable to the priming treatment of high-value herbaceous flower seeds, and is especially applicable to seeds with mucus on surfaces such as pansy, and particle seeds such as petunia hybrida.

Description

technical field [0001] The invention relates to seed treatment and seed physiological application technology, in particular to a priming treatment method for grass flower seeds. Background technique [0002] Seed initiation is the second stage of controlling the slow absorption of water by the seeds so that they stay in the imbibition, allowing the seeds to perform the physiological and biochemical metabolism and repair of pre-germination, so that the seeds are in a metabolic state ready to germinate, but prevent the radicle from protruding. The primed seeds have enhanced vigor, strong stress resistance, fast and uniform emergence, and a high seedling rate. There are many domestic patent applications related to seed priming technology. CN101411329A discloses a tobacco seed initiator; CN1190123C discloses a solid priming method for improving seed vigor; CN100420381C discloses a seed initiator. [0003] Pansy, Petunia, Begonia, Primula, Impatiens, Salvia, Verbena and other he...
