Daffodil seed stem preservation method

Abstract

The invention discloses a daffodil seed stem preservation method. The method comprises the following aspects: (1) processing a seed stem, choosing a high-quality corm, slightly removing an outer filmof the seed stem with hands, and then sterilizing; (2) coating a film, adding chitosan and penicillin into a fermentation solution, stirring, mixing, preserving heat to obtain a film coating solution,baking the sterilized seed stem at the low temperature, and soaking in the film coating solution; (3) irradiating at the low temperature, putting the film coated seed stem into a variable temperaturechamber to process at the variable temperatures, and irradiating through ultraviolet light under the low temperature condition, (4) preserving, levelling fine sand at the bottom part of a sand pit, spreading screened fine earth, spreading the processed seed stem on the screened fine earth, respectively spreading the screened fine earth and the fine sand, horizontally placing a bamboo tube on themiddle layer of the seed stem, spreading an ice bag at the upper part of a sand pile, and using an old quilt and a plastic film to wrap the sand pile; (5) accelerating germination: airing the preserved seed stem in the sun, soaking in an aspirin solution, accelerating germination at the constant temperature, and cultivating the seed stem after accelerating germination.

Problems solved by technology

[0003] The present invention is aimed at existing problem: its growth period of small-sized stem is short, adaptability is poor, is not suitable for selling, needs to replant and cultivate in September-October; Crucial impact, the traditional stacking method has serious water loss and is vulnerable to pests, resulting in low germination rate and high rate of disease and insect pests after planting. The effect of low temperature storage is good, but the cost is high
