Method for promoting germination of epimedium sagittatum seeds

Abstract

The invention discloses a method for promoting germination of epimedium sagittatum seeds. The method comprises the following operation steps that after pollination of epimedium sagittatum is finished,1 / 2 of whole rachises at the upper ends of the rachises are sheared off, and a proper shading condition is provided for epimedium sagittatum living plants; air-drying is carried out in an indoor natural state, and seed coats are removed; the seeds are soaked 2-3 times, then a carbendazim or chlorothalonil stock solution is diluted by 500-600 times to soak the seeds, and then washing and airing are carried out; and the seeds and perlite are mixed, clean water is added into the perlite until the water content reaches 75%-82%, storage is conducted in a dark place for 120 days, and then the seedsbegin to sprout. According to the method, after-ripening of epimedium sagittatum in form and physiology is broken through by using a physical treatment method, growth and development of seed embryosare promoted, the seed germination time is shortened, and the seed germination rate is increased; and the perlite serves as a storage substrate, water retention is stable, sinking is not easy, the airpermeability is good, the seed rotting and mildewing phenomena are less, and the seed germination rate can be increased by 5%-15%.

Description

technical field [0001] The invention belongs to the field of herbal medicine planting, and in particular relates to a method for promoting the germination of Epimedium sagittatum seeds. Background technique [0002] Epimedium sagittatum is a plant of the genus Epimedium Berberidaceae, which is a perennial herb, and the rhizome of Epimedium sagittarius is nodular in crawling shape. 1-3 leaves from roots, 3 compound leaves, leaflets ovate to ovate-lanceolate, 4-9 cm long, 2.5-5 cm wide, apex pointed or acuminate, with fine bristles on the margin, base Heart-shaped, the base of the lateral leaflets is asymmetrical, the outer lobe is oblique and larger, triangular, the inner lobe is smaller and nearly round; cauline leaves are often opposite at the top, similar in shape to root leaves, and the base is crooked arrow Heart-shaped, the outer lobe is very large and the apex is acuminate. [0003] Epimedium sagitta is an important medicinal resource in my country, mainly distribute...

Problems solved by technology

[0004] The existing epimedium is mainly collected from wild plant resources. With the increase of demand, the amount of collection and consumption has exceeded the regeneration capacity of natural resources, resulting in endangered species

[0005] At present, the main methods for promoting the seed morphology and physiological post-ripening of Epimedium sagittatum are: constant temperature treatment and variable temperature treatment. The substrate is mainly river sand. The advantage of river sand is that it has a better heat preservation effect. The requirements for the loaded materials are high, and the water retention effect is not ideal. Due to the sinking of the water, the frequency of manual turning and the frequency of water replenishment and moisturizing are frequent. In addition, the river sand has poor air permeability, rotten seeds and mildew.
