Method for increasing germination rate of Vitex negundo seeds

Abstract

The invention relates to a method for increasing the germination rate of Vitex negundo seeds. The method comprises the steps of rubbing with abrasive paper, thinning seed coats, and processing Vitex negundo seeds in a coating manner with a solution consisting of biomass charcoal and wood vinegar. Through the combined treatment of the biomass charcoal and the wood vinegar, nutrients are provided for seed germination, the water absorption and germination of seeds are promoted, and the germination rate of the Vitex negundo seeds is enhanced. The method significantly improves the germination rateof the Vitex negundo seeds, is convenient to apply, simple to operate and easy to widely promote, and meets the application of large-area sowing in harsh environments such as barren hills or destructive lands.

Description

Technical field [0001] The invention relates to a treatment method that can increase the germination rate of harvested wild Vitex negundo L. var. heterophylla seeds. Through the compound treatment of biomass charcoal and wood vinegar liquid, it provides nutrient elements for seed germination and promotes water absorption by seeds Germination, increase the germination rate of Vitex spp. The method is highly efficient, environmentally friendly and easy to operate, and can be put into application on a large scale. Background technique [0002] Vitex is mainly distributed in northern China. It often grows on the sunny slopes of mountains and forms shrubs. It has the characteristics of cold resistance, drought resistance, barren tolerance, strong stress resistance, and developed root systems. It is very suitable for growth in western Liaoning. For western Liaoning, Vitex is an important tree species for soil and water conservation, and it is also an indicator plant in arid areas of w...

Problems solved by technology

[0004] At present, there are mainly two kinds of techniques for improving the germination rate of Vitex twig seeds: one is to adopt chemical germination method, and use gibberellin solutions of different concentrations to improve the germination rate of the seeds, and the highest average germination rate can reach about 70%. The disadvantage is that the gibberellin solution is unstable, and the treated seeds need to be used and prepared immediately, and the germination rate of the treated seeds is still not high; the other is an engineering treatment method: use sand storage to break dormancy, and sand storage for 60 to 180 days In spring, take out the sand hidden seeds, put them in a sunny place and cover them with wet sacks to accelerate germination, and sow them in mid-to-late April

The disadvantage of this method is that the processing time is too long, which limits the engineering time. In addition, the process is relatively complicated, and the seedlings are not uniform, and the cost of processing and management is relatively high.
