Organic seed-dressing agent for direct-seeding rice and preparation method of organic seed-dressing agent

Abstract

The invention discloses an organic seed-dressing agent for direct-seeding rice and a preparation method of the organic seed-dressing agent. The organic seed-dressing agent is prepared from the following raw materials in parts by weight: 30 to 40 parts of compound organic fertilizer, 5 to 10 parts of herba speranskiae tuberculatae extract, 1 to 3 parts of acid regulating agent, 5 to 10 parts of Hyoscyamus niger extract, 5 to 10 parts of compound humus bacteria, 5 to 10 parts of nutrient compound, 3 to 5 parts of jasmine oil, 1 to 3 parts of bactericide, 3 to 5 parts of corn flour and 1 to 3 parts of potassium fulvate. The invention relates to the technical field of crop planting agents. According to the organic seed-dressing agent for the direct-seeding rice and the preparation method, environment-friendly use can be realized, the use of harmful chemicals is reduced by adopting an organic matter fertilizer to be matched with a complex microbial inoculant, a seed-dressing agent is harmless to the environment by directly using natural seed-dressing nutrient substances, and the condition that a large amount of bacteriostatic drugs is used in the seed-dressing agent cause great influence on environment is avoided. The seed-dressing agent provided by the invention has strong pertinence, and has the functions and effects of seedling support, root ventilation, seedling fertilization, seedbed water retention, matrix acidity adjustment, disinfection and sterilization.

Description

technical field [0001] The invention relates to the technical field of crop planting agents, in particular to an organic seed dressing agent for direct-seeding rice and a preparation method thereof. Background technique [0002] Direct-seeding rice (rice direct-broadcasting) refers to the cultivation technology that directly sows rice seeds into the shallow soil layer of 1-2cm without the operation of raising seedlings, pulling seedlings and transplanting in the process of rice cultivation. In comparison, it has the advantages of provincial planting, seedling saving, labor saving, labor saving, and investment saving. The live broadcast method is increasingly adopted by large planters, and the planting area is also increasing year by year. However, direct seeding rice also has difficulties in emergence, heavy weeds, and easy Lodging, late maturity and other disadvantages, direct seeding rice needs to enhance the competitive advantage of seedlings and weeds at the seedling sta...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides an organic seed dressing agent for direct-seeding rice and a preparation method, which solves the problem that the existing direct-seeding rice needs to use a seed dressing agent when dressing seeds, and a large amount of organic seed dressing agents are used in the existing seed dressing agents Bacteriostatic drugs have a great impact on the environment and cannot be used in an environmentally friendly manner. It is impossible to reduce the use of harmful chemicals by using organic fertilizers combined with compound bacterial agents, and it is impossible to directly use natural seed dressing nutrients to make seed dressing environmental hazards
