Treatment agent for hard seeds

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...
