Seed germination acceleration method

Abstract

The invention discloses a seed germination acceleration method, relates to a production method of crop seeds, and belongs to the field of seed treatment. The method is characterized by comprising the following steps: soaking seeds in a 0.5% copper sulfate aqueous solution for 15-20 minutes; washing the seeds after being taken with clear water, airing and placing in an environment with the ventilation volume of 20L / min, wherein the germination acceleration temperature is 25-28 DEG C, and the illumination of a phytotron in germination acceleration is performed in a light and dark alternation manner at a 4 hour interval; and after the treatment, covering the seeds with sand, and watering and icing, wherein the thickness sum of the seeds and covering sand and ice is 40-50cm. The method disclosed by the invention has the beneficial effects that the good seeds which are full without pest and disease damages are selected; the seeds are mixed with the water and the sand and subjected to the freezing stacking treatment, the resting stage of the seeds is effectively broken, the germination rate of the seeds and the emergence rate of a nursery are increased, the seeding quantity is reduced, and the reproduction coefficient is greatly increased; by adopting the technology, the nutrition resistance and disease / pest resistance of the seedlings are improved, and the self-epidemic prevention system of the seeds is mobilized.

Description

technical field

[0001] The invention relates to a method for producing crop seeds, which belongs to the field of seed treatment, in particular to a method for accelerating germination of seeds. Background technique

[0002] Pregermination is a measure that can cause bud growth, dormant bud development, and seed germination, or promote these pre-germination measures; it is to ensure that the nutrients in the seeds are quickly decomposed and run after the seeds absorb enough water to supply the young embryos for growth. important measure.

[0003] Many vegetable seeds need to germinate. Generally, the seeds that need to be germinated can be divided into two categories: one is that the seeds of fruit and vegetable vegetables germinate slowly and need to be germinated, such as tomatoes, peppers, eggplants, and cucumbers; the other is that the summer temperature is high, resulting in Vegetable seeds have a low germination rate, so they also need to be stimulated, such as lettuce...

Examples

Embodiment 1

[0015] Embodiment 1 (for testing kind is cypress tree species)

[0016] 1. Select 4000g of high-quality cypress seeds with full seeds and no pests and diseases, pack them into several bags, soak them in 0.5% copper sulfate aqueous solution for 15-20 minutes, take them out, rinse them with clean water, and dry them for later use;

[0017] 2. Pack the sterilized seeds into distilled water bottles and add tap water; put the distilled water bottles containing seeds and water into the artificial climate chamber, and immediately ventilate the bottles with an air compressor, and finally turn the water outlet Wrap it with double-layer clean gauze to prevent external bacteria from entering and contaminating the seeds; the ventilation rate of each bottle is 20L / min; the germination temperature is 28°C, and the artificial climate chamber light time is light / dark alternately once for germination, 4h each;

[0018] 3. In the first ten days of November, choose a shady and ventilated place w...
