Breeding method for saffron small seed ball rejuvenated seeds

Abstract

The invention discloses a breeding method for saffron small seed ball rejuvenated seeds. The breeding method comprises: a) collecting saffron bulbs into a room, airing the saffron bulbs in the room, dividing the saffron bulbs into saffron large bulbs with unit weight of 10g or more and saffron small bulbs with unit weight of 10g or less, b) storing the saffron small bulbs in a flat round split-bamboo basket, removing dried roots of the saffron small bulbs and wiping out the residual leaf sheaths, c) after storage of the saffron small bulbs for 2 to 3 months, humidifying the ground in the roomwhere the saffron small bulbs are stored, d) after one month, putting the saffron small bulbs into a plug seedling tray and carrying out germination so that small bulb sprouts are obtained, and e) after 1 to 2 months, planting the small bulb sprouts to the field. The method can rejuvenate the small bulbs with unit weight 10 grams or less. The discarded saffron small bulbs are cultivated into seedballs by rejuvenation so that the wastes are used, saffron seed ball production is solved and the high economic effects are obtained.

Description

technical field [0001] The invention relates to a propagation method for seed bulb rejuvenation of saffron. Background technique [0002] Saffron, also known as saffron and saffron, belongs to the herbaceous plant of Iridaceae. It is a rare and precious Chinese medicinal material that is currently in short supply in the domestic and foreign markets. It can not only treat various diseases such as epilepsy, postpartum congestion, wet spots, depression, depression, palpitations and madness, but also a water-soluble natural pigment and tonic. It is used as food, beverage, soup, Coloring and flavoring of fragrances and cosmetics. Known as "red gold" and "plant gold", it has extremely high economic value. [0003] With the gradual understanding of consumers' disease prevention and health care functions of saffron, the market demand for saffron is increasing year by year. According to preliminary statistics, the domestic market currently consumes nearly 30,000 kilograms of saffr...

AI Technical Summary

Problems solved by technology

Because saffron cannot bloom and set fruit, sexual reproduction cannot be used in production to produce bulbs, and there are no successful cases of tissue culture methods. At present, farmers can only use bulbs of more than 15g each for seed bulb propagation.

However, in the bulb propagation process, generally a large bulb can only reproduce 1-2 new bulbs for seeding in a year, and the requirements for its breeding technology are very high. Many farmers keep their own bulbs due to management technical problems, resulting in rotten seeds or Degenerated, very low reproduction coefficient

Moreover, bulblets above 10g cannot be used for breeding in production, and these large numbers of bulblets of saffron are discarded without any production value.
