Embodiment 1

[0019] see figure 1 , the technical scheme of the soybean rhizobia seed dressing agent provided by the present invention: soybean rhizobia seed dressing agent, said soybean rhizobia is a class that can co-exist with leguminous crops, and satisfies the nitrogen required for crop growth by fixing nitrogen in the atmosphere The microbe of prime comprises the following steps: Step 1: select the raw material Burnet, Folium Artemisiae Argyi, Arborvitae leaf, nutmeg, cumin, myrrh and rush to prepare the rhizobia seed dressing;

[0020] Step 2: Mix and pulverize the components of the formula amount, add 20 times the weight of water to decoct and extract twice, each time for 2 hours, combine and concentrate the filtrate to contain 1g of the original medicinal material per 1mL, and obtain the concentrated solution of the medicine. The concentrate is diluted 250 times with water;

[0021] Step 3: When dressing the seeds, first mix the protective agent in the small bag and the rhizobia a...

Abstract

The embodiment of the invention discloses a bradyrhizobium japonicum seed dressing agent, which is a class of microorganisms capable of being symbiotic with leguminous crops and meeting nitrogen required by crop growth by fixing nitrogen in the atmosphere. The method comprises the following steps: 1, selecting raw materials for preparing a bradyrhizobium japonicum seed dressing agent, wherein theraw materials comprise: sanguisorba officinalis, folium artemisiae argyi, cacumen biotae, nutmeg, fennel, myrrh and juncus effuses; 2, mixing the components according to the formula ratio, crushing, adding 20 times by weight of water, decocting and extracting for 2 h twice, combining and concentrating the filtrates until every 1 mL of the filtrate contains 1 g of the raw medicinal material to obtain a medicament concentrated solution, and diluting the medicament concentrated solution with water by 250 times; 3, during seed dressing, uniformly mixing a protective agent in a small bag and the bradyrhizobium japonicum agent in a plastic bag, and carrying out seed dressing; and 4, after seed dressing, storing in a shady, cool and dark environment, and sowing the seeds in time within three days. The bradyrhizobium japonicum seed dressing agent can also induce plants to generate systematic resistance, so that the probability of diseases of crops is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of strain application, in particular to soybean rhizobium seed dressing agents. Background technique [0002] my country's soybean imports have reached 80 million tons, and the self-sufficiency rate of Chinese edible oil is less than 40%, so it is necessary to revitalize soybeans in Northeast China. This year, the state implemented a structure adjustment plan in the Northeast to suppress corn, and the state implemented a market target price subsidy for soybeans. Fuxin encountered an opportunity to develop soybeans. The average yield of soybeans in Fuxin is only 150 kilograms. How to increase the yield has become the goal of joint efforts of farmers and scientific and technological personnel. [0003] The use of rhizobia in soybean production is a mature and widely used technology, which can greatly improve the nitrogen fixation capacity of soybeans during the growth period, and sup...
