Device for breaking dormancy of hard seeds of round leaf morning glories and method for promoting germination

Abstract

The invention discloses a device for breaking dormancy of hard seeds of round leaf morning glories, which comprises a hard seed friction box and an upper friction pressing plate. The invention also discloses a method for breaking the dormancy of hard seeds of round leaf morning glories and promoting germination, which comprises the following steps of: (1) selecting seeds; (2) putting the seeds into the friction box, and pressing the upper friction pressing plate used for covering heavy on the seeds for pushing and pulling back and forth to ensure that the seeds begin to germinate; and (3) carrying out a germination experiment on the hard seeds subjected to friction by using a paper-to-paper or grit germination method. The invention efficiently breaks the dormancy of the hard seeds of the round leaf morning glories through a physics friction method without any chemical reagent or hormone treatment. Compared with other physics friction methods, the invention does not damage the seeds, can reduce the hard seed rate to be less than 5 percentage after treatment from more than 80 percentage before treatment, and greatly improves the germination rate of the seeds. The invention has the advantages of ecological protection, simple method and lower cost.

Description

Technical field [0001] The invention relates to a treatment device for breaking the hard dormancy of flower seeds and a method for treating seeds with the aforementioned device to promote seed germination, and belongs to the technical field of flower planting.

Problems solved by technology

[0003] Round-leaf morning glory has strong adaptability, fast growth, luxuriant flowers and leaves, and strong covering power. The flowering period lasts for 4-5 months. It is resistant to heat, drought, and poor soil. It is a good material for landscaping, artificial landscaping, and beautification of family yards. However, the seeds of morning glory round leaves are dense and hard, with poor water absorption capacity and a hard rate of more than 80%, which brings great difficulties to artificial cultivation and utilization. Seed treatment must be carried out before sowing , break the hard dormancy of morning glory seeds and increase the germination rate of seeds

[0004] The application number is 200810017529.9 Chinese invention patent application open specification discloses a kind of method for breaking the hard dormancy of alfalfa seeds, the method adopts inoculating Penicillium, Aspergillus oryzae or Trichoderma viride, or the combination of above-mentioned strains to process alfalfa seeds, solves the problem of breaking The problem of hard dormancy of alfalfa seeds, this method is complicated to operate and not suitable for morning glory seeds

[0005] The application number is 200910133123.1 Chinese Invention Patent Application Publication, which discloses a method for breaking the hardness of leguminous seeds. The method uses concentrated sulfuric acid to dress the seeds, and then stirs and neutralizes them with strong alkaline salt solution or lye. This method requires a large amount of Acid and alkali, high treatment cost, safety and pollution problems, improper treatment will affect seed germination and seedling growth
