Treatment method capable of improving germination ability of hibiscus hamabo

Abstract

The invention relates to the technical field of planting and discloses a treatment method capable of improving germination ability of hibiscus hamabo. The treatment method includes: soaking, vacuum heating, blending seeds, and accelerating germination. The method is simple, convenient to operate and needless of high-temperature treatment, hibiscus hamabo seeds can germinate after 8-9 days of germination accelerating, and germination rate reaches 53.7%, so that propagation efficiency of the hibiscus hamabo seeds is improved obviously, and propagation cost is saved greatly. The seeds are put ina compound enzyme solution for soaking to damage tissue structure of seed husks, so that the seeds are promoted to absorb outside nutritional ingredients, and growth of radicle and germ is promoted; the seeds after being soaked are put into a vacuum rotary evaporator for vacuum heating to damage activity of dormant substances, so that seed dormancy is broken, seed protoplasm activity is improved,and seed germination is accelerated; a seed dressing agent is added into the seeds after vacuum heating, nutrition is rich, molding and rotting of the seeds are avoided, growth of the seed radicle andgerm is promoted, seed germination is accelerated, and seed propagation efficiency of hibiscus hamabo is improved.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a treatment method for improving the germination ability of seaside hibiscus. Background technique [0002] Seaside hibiscus generally grows in seaside saline-alkali land, with golden color and bright and beautiful flowers. It is an excellent garden greening seedling, and it is also a good windbreak and sand-fixing, embankment and moisture-proof seedling. It can be used as coastal protection forest. However, the seed shell is hard and the germination rate is low. Before sowing, it is necessary to soak the seeds in warm water to break the dormancy of the seeds. The document "Influence of Soaking Seeds at Different Temperatures on the Germination Rate of Seaside Hibiscus Seeds, Xu Senfu et al. Soak in cold water for 48 hours, and then put it into a petri dish for germination test. After 40 days, the germination rates of the seeds were 21.67%, 28.33%, 23.33%, and 26.67%, res...

After the 40th day, few seeds germinated. The germination rate is extremely low, which obviously reduces the sowing and reproduction efficiency of seaside hibiscus, and causes a lot of waste of seeds
