The invention provides a rice seed soaking agent and application thereof, and relates to the technical field of rice seed soaking agents. The seed soaking agent comprises the following raw materials in percentage by weight: 1-1.5% of plant growth regulator, 7-16% of insecticide, 20-30% of film-forming agent, 35-50% of nutritional agent, 0.5-1.5% of microbial agent and 10-20% of water; the film-forming agent comprises seaweed powder, sodium carboxymethylcellulose and chitin; the nutrient comprises ammonium carbonate, sodium carbonate, zinc fertilizer, boron fertilizer and organic fertilizer; the microbial agent comprises bacillus subtilis, trichoderma and arbuscular mycorrhizal agents. According to the invention, through testing rice seeds of different varieties, even under the condition that the seeds are unfavorable for germination at 12 ℃, the rice seeds can still germinate in about 2d, and the later-stage tillering number is more than 15.2 tillering/plant on average. Therefore, the rice seed soaking agent can be applied to improving the tillering number and the bakanae disease resistance of rice. |
