Bulbus fritillariae cirrhosae seed stratification treatment method

Abstract

The invention discloses a bulbus fritillariae cirrhosae seed stratification treatment method. The bulbus fritillariae cirrhosae seed stratification treatment method specifically comprises the following steps that coco coir and vermiculite are used as Zhaotong bulbus fritillariae cirrhosae seed treatment matrixes; a layer of the matrixes are laid at the bottom of a container, then fritillaria capsules are cut off and uniformly laid on the matrixes, the fritillaria capsules and scattered seeds are placed into the matrixes in the middle of the container according to a mode of laying the matrix layer by layer and laying the seeds layer by layer, and finally, the a layer of matrixes cover the top; a vent hole is reserved in the container; the container is put into a variable-temperature incubator for accelerating germination, and firstly the temperature of the incubator is arranged to be 9.5-11 DEG C and the treatment period is arranged to be 40-50 days; the temperature of the incubator iscontrolled to be 5.5-7.5 DEG C and the treatment period is controlled to be 40-50 days; and finally, the temperature of the incubator is controlled to be 0-2 DEG C, treating is carried out for 50-60 days, and vernalization is finished. According to the bulbus fritillariae cirrhosae seed accelerating germination method, the whole period is 150-160 days, and the seedling emergence time is 45-50 days. The germination rate is high, and the seedling formation period is shortened; and the germination rate of Zhaotong fritillaria seeds treated by the method reaches 90% or above in the first ten daysof February of the next year.

Description

technical field [0001] The invention belongs to the technical field of medicinal material cultivation, and in particular relates to a method for stratifying and treating Fritillaria sichuanensis seeds. Background technique [0002] There are two main types of current stratification treatment methods for Fritillaria fritillaria seeds: 1. The traditional outdoor pit-buried stratification method; In the treatment stage, stratification treatment is carried out, and the substrate humidity is kept below 20%). The main disadvantage of the pit burial method is that it is difficult to manually control the stratification process, which is greatly affected by natural climate factors and soil environmental factors, and it is difficult to control the actual post-ripening of the seeds. It is estimated that the two-stage temperature-variable stratification is set at a slightly higher temperature, and the humidity of the substrate is not enough, and there is no key technical measure of ult...

Problems solved by technology

The main disadvantage of the pit burial method is that it is difficult to manually control the stratification process, which is greatly affected by natural climate factors and soil environmental factors, and it is difficult to control the actual post-ripening of the seeds. It is estimated that the two-stage temperature-variable stratification is set at a slightly higher temperature, and the humidity of the substrate is not enough, and there is no key technical measure of ultra-low temperature refrigeration, which is not enough to promote the formation of physiological substances for seed germination. Therefore, the stratification period should be more than 180 days, and the seeds The germination rate is not high, only about 70%, which is not enough for the effective growth time of Fritillaria seedlings in the first year after sowing in the next year
