Seed soaking agent for crop seeds based on actinomycetes and its preparation method and seed soaking method

Abstract

The invention specifically discloses a crop seed soaking agent based on actinomycete as well as a preparation method and a seed soaking method of the crop seed soaking agent. The crop seed soaking agent comprises effective components of secondary metabolite of actinomycete, wherein the actinomycete is louche streptomyce D74 or / and dense spiral streptomyce SG712100. The preparation method comprises the following steps of: inoculating an activated louche streptomyce or / and dense spiral streptomyce culture into a Gause No.1 liquid culture medium, performing shaking culture by using a shaking bed, performing suction filtration, filtering and sterilizing, thereby obtaining actinomycete acellular fermentation filtrate, namely secondary metabolite of the actinomycete. The seed soaking method comprises the following steps of: putting crop seeds into the diluted acellular fermentation filtrate, soaking, abandoning the soaking liquid, drying the crop seeds at a shade place, and seeding. By adopting the crop seed soaking agent, crop seed germination and seedling growth can be remarkably improved, the disease resistance of crops can be improved, the yield of crops can be increased, and meanwhile no damage or pollution can be done to human beings, livestock or environment.

Description

Technical field [0001] The invention relates to the field of plant growth conditioners, in particular to an actinomycete-based crop seed soaking agent, and a preparation method and a seed soaking method. Background technique [0002] Seed treatment is a technology that uses physical, chemical and biological methods to provide protection against insects and diseases for crop seeds, and promote the emergence and healthy growth of crops. Seed treatment techniques mainly include seed coating, seed pelleting, seed soaking and seed dressing. The seed treatment method is simple, the cost is low, and the effect of disease prevention and growth promotion is good. Since the 1950s, my country has used chemical soaking and seed dressing to prevent and control underground pests and seedling diseases of crops. However, most of the commonly used seed soaking agents are chemical products, which are mainly used to prevent insects and diseases. There is no growth-promoting seed soaking agent tha...

AI Technical Summary

Problems solved by technology

However, most of the commonly used seed soaking agents are chemical products, which are mainly used for insect control and disease prevention. There is no growth-promoting seed soaking agent that uses actinomycete fermentation products as active ingredients.
