preparation example Construction

[0029] In the present invention, the preparation method of the compound comprises the following steps:

[0030] (1) Mix Ningnan·Azoxystrobin with water to obtain a diluted medicament; the volume ratio of the Ningnan·Azoxystrobin suspension concentrate mixed with water is 0.84:674.16;

[0031] (2) mixing the Bacillus Velez HN-Q-8 fermented liquid with water to obtain a diluted bacterial agent; the volume ratio of the Bacillus Velez HN-Q-8 fermented liquid mixed with water is 450:225;

[0032] (3) After mixing the diluting medicament and the diluting bacterial agent, a compound agent is obtained;

[0033] Step (1) and step (2) are not limited in sequence.

[0034] The present invention does not have any limitation on the mixing methods of step (1), step (2) and step (3), and the methods well known to those skilled in the art can be adopted.

[0035] In the present invention, the mixed volume ratio of the diluted bacterial agent and the diluted medicament in step (3) is 3:7.

Abstract

The invention relates to a compound agent for promoting the growth of potato seedlings and its application, in particular to the field of medicaments. The present invention is a compound agent for promoting the growth of potato seedlings, the active ingredients of the compound agent include the fermented liquid of Bacillus velezensis (Bacillus velezensis) HN-Q-8 and Ningnan Azoxystrobin suspension concentrate; The preservation number of Bacillus surbelles HN-Q-8 is CGMCC No.19554. The compound agent of the invention can promote the growth of plants and avoid the problem of soil compaction.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a compound agent for promoting the growth of potato seedlings and its application. Background technique [0002] Potatoes are the fourth largest food crop in the world, after rice, wheat and corn. The growth and development of potato is a very complex life process, which not only requires organic and inorganic substances as structural substances and nutrients for cell life activities, but also requires the regulation and control of plant growth substances. For the purpose of increasing production, technicians in the planting industry often blindly use excessive fertilizers, especially chemical fertilizers, which will cause soil compaction in cultivated land. It can be seen that how to produce a bacterial agent that can significantly improve the growth of potatoes without causing soil compaction is very important. Contents of the invention [0003] In order to solve the above pro...
