Sowing breeding method for helleborus thibetanus

Abstract

The invention relates to a sowing breeding method for helleborus thibetanus. The method comprises the following steps: (1) harvesting seeds: taking the black seeds in follicles of the helleborus thibetanus, and storing the black seeds in a cool and ventilated place; (2) preserving the seeds in sand for accelerating germination: flatly spreading the black seeds of the helleborus thibetanus in a sand bed, and keeping the sand bed moist; and (3) performing sowing after germination: observing whether the seeds in the sand bed are germinated, when 30% of small seed buds break seed coats, screeningout the seeds from the sand bed, performing washing, and performing direct sowing in soil. Compared with the prior art, the method provided by the invention utilizes a process of preserving the seedsin the sand for accelerating germination to simulate a natural process that the seeds have after-ripening after being covered by fallen leaves, makes an after-ripening process of the helleborus thibetanus seeds shortened to achieve the effect that the seeds germinate in a current year and have a high germination rate, and can better solve the problem of seedling supply in the market.

Description

technical field [0001] The invention relates to a plant breeding method, in particular to a seeding and breeding method of iron chopsticks. Background technique [0002] Iron chopsticks is a plant of the genus Iron chopsticks in the family Ranunculaceae. It is a perennial evergreen herb with kidney-shaped or pentagonal leaves, three-segmented chicken feet, cauline leaves that are nearly sessile, and basal leaves that are smaller. Flowers on stems or branches, open when basal leaves just emerge, glabrous; sepals are initially pink and turn green during fruiting. In East China, the flowering period is in March and the fruiting period is in May. Because of its unique flower shape, iron chopsticks bloom in early spring, have few pests and diseases, and have strong shade tolerance. They can be planted in large areas and are excellent materials for understory ground cover plants. As an excellent native garden plant, iron chopsticks are gradually recognized by everyone because of...

Problems solved by technology

Seeds need to fall on the ground naturally, covered by fallen leaves, low temperature in winter and soaked in rain and snow, so that the seeds can be matured after reaching a germinating nutritional state before they can germinate. Large, limited supply of seedlings
