Problems solved by technology

[0006] The research on breaking dormancy of hard seeds in the past 20 years shows that the quality of hard seeds after storage is higher than that of non-hard seeds. Therefore, in production application and germplasm preservation, hard seeds can be considered to be preserved, but when hard seeds are processed before sowing , tends to cause certain damage to hard seeds, which enables producers to take correct measures to eliminate such concerns when they are determined to study the treatment methods

Embodiment 1

[0018] 1. Expose the seeds in the sun to make the water content of the seeds reach 12% for later use;

[0019] 2. Put the dried and pretreated seeds in a container, put them in a constant temperature box or a drying box, and implement a step-by-step treatment process from low to high temperature: the first step is to treat at -8°C for 24 hours, and the second step is to Treat at a constant temperature of 20°C for 24 hours, and in the third step, treat at a constant temperature of 30°C for 120 hours, then allow it to cool down to room temperature naturally for later use;

[0020] 3. Move the high-temperature-treated seeds into a covered container covered with absorbent paper, spray the seeds with distilled water using a sprayer, and immerse the seeds in clean water when the surface of the seeds is wet and no clear water appears. Cover, and then put it in the refrigerator for 1685 hours at a constant temperature of 0°C, and then expose it to the sun to make the water content of ...

Embodiment 2

[0023] 1. Dry the seeds at a low temperature below 30°C to make the water content of the seeds reach 14% for later use;

[0024] 2. Put the dried and pretreated seeds in a container, put them in a constant temperature box or a drying box, and implement a step-by-step treatment process from low to high temperature: the first step is to treat at -6°C for 25 hours, and the second step is to Treat at a constant temperature of 22°C for 25 hours, and the third step is to treat at a constant temperature of 32°C for 125 hours, and then let it cool down to room temperature for later use;

[0025] 3. Move the high-temperature-treated seeds into a covered container covered with absorbent paper, spray the seeds with distilled water using a sprayer, and immerse the seeds in clean water when the surface of the seeds is wet and no clear water appears. Cover, and then put it in the refrigerator for 173 hours at a constant temperature of 1°C, and then dry it at a low temperature below 30°C to ...

Abstract

The invention discloses a treatment agent for hard seeds, relates to a seed treatment agent, and belongs to the technical field of agriculture. The invntion is characterized by comprising low temperature treatment, normal temperature treatment, high temperature treatment and microbial agent treatment. The invention has the following beneficial effects: temperature is employed to conduct stimulation treatment on the seeds, and the stimulation treatment comprises steps of: low temperature treatment, normal temperature treatment, high temperature treatment and microbial agent treatment. The microbial agent contains Bacillus subtilis and thiamethoxam. Poikilothermic treatment on seeds has advantages of improving the seed germination rate, sterilizing, reducing crop diseases and pests at seedling period and reducing the use of pesticides. Microbial agent treatment breaks confinement of traditional physical and chemical methods for seed treatment. The invention provides a simple and feasible biological treatment method from a unique perspective and rational microbial agent combination to solve the long-standing problem of low seed germination rate, and has great significance to the green environmental protection; and the method provided by the invention has no toxic effects on germinating seeds, and can benefit germination due to temperature stimulation and nutrients from the microbial agent.

Description

[0001] technical field [0002] The invention relates to a seed treatment agent, which belongs to the technical field of agriculture, in particular to a treatment agent for hard seeds. Background technique [0003] Hardness is one of the types of seed dormancy, which is caused by the impermeability of the seed coat. For plants themselves, the formation of hard seeds is not only a very important life activity process, but also a biological adaptation to environmental conditions and seasonal changes that plants have acquired through long-term evolution. For example, in the process of hard fruit formation, the degree of dormancy is different due to the different parts of the fruit and the sequence of ripening time. In this way, the time for relieving dormancy is also inconsistent, resulting in irregular germination. Hard seeds can germinate and grow under suitable conditions in a certain period of time, which enhances the adaptability to adverse environments and is beneficia...
