Simple method for improving seed germination of canna edulis ker

Abstract

The invention belongs to the technical field of seed germination, and discloses a simple method for improving seed germination of canna edulis ker. The simple method comprises the following steps that fully ripe fruits are harvested, seeds are stripped out, shrunk immature seeds and impurities are removed, and the seeds are hung in a shady, cool and ventilated place by using a net cage for natural drying; at the end of April and the beginning of May, seed soaking and germination accelerating are started when the air temperature is stabilized to be 16 DEG C or above; high-temperature water which is boiled to 90 DEG C is poured into a pot containing the canna edulis ker seeds, soaking is carried out for 3 hours, and soaking water is poured out; water is re-boiled to 90 DEG C, soaking is carried out for 20 hours, and the seeds are washed with clear water; ridging and compartment sowing are carried out, compartment surfaces are flat, the compartment surfaces are thoroughly sprayed and watered before sowing, and a layer of dry fine soil is scattered on the compartment surfaces; the seeds are uniformly scattered and covered with a layer of fine soil after sowing, and the seeds are thoroughly watered with mist; and a small arched shed is built for heat preservation and germination acceleration, soil humidity is observed, drying and water supplementing are carried out, and two ends of the arched shed are opened in sunny days after seedlings emerge from the soil. The hard seeds of canna edulis ker are treated by using a two-time high-temperature water scalding method, and the method is simple, convenient and easy to operate, labor-saving, time-saving and economical.

Description

technical field [0001] The invention belongs to the technical field of seed germination, and in particular relates to a simple and convenient method for improving the germination of plantain taro seeds. Background technique [0002] Canna taro is a hard seed with poor seed coat permeability, so it is difficult to germinate in conventional sowing. Zhou Yuanqing, Zhang Wen'e and Ou Guigui reported the germination characteristics of hard seeds of canna and plantain taro respectively. They used concentrated sulfuric acid to break the barrier of the palisade tissue and destroy the oil layer and wax layer on the surface of the seed coat, thereby increasing the permeability of the seed coat and improving the germination effect. ; Wei Qi is still an invention patent obtained by using concentrated sulfuric acid treatment. Concentrated sulfuric acid treatment is dangerous to operate, and banned chemicals are generally not easy to buy. Third, soaking for too long will produce deformed ...

AI Technical Summary

Problems solved by technology

[0004] (1) In the existing method of using concentrated sulfuric acid acid etching to break the barrier of the palisade tissue of plantain taro and destroy the oil layer and wax layer on the surface of the seed coat, the concentrated sulfuric acid treatment is dangerous to operate, and chemicals are banned, which are generally not easy to buy. Third, soaking for too long will produce deformed seedlings or even burn the seeds

[0005] (2) In the existing method of cutting off part of the seed coat of the plantain taro to make the seeds white, increase the permeability of the seeds to improve the germination effect, the process of cutting the seed coat is labor-intensive and time-consuming, and is not easy to operate

[0006] (3) In the existing method of using borax water to immerse low-temperature freezing, self-made solution soaking, incubator germination to improve germination effect, the operation is cumbersome, labor-intensive and time-consuming, and difficult to operate
