Problems solved by technology

[0010] However, the traditional techniques mentioned above have only sporadic effects because they simply employ soil microorganisms as traditional fertilizer additives or soil conditioner components
Furthermore, until now, the use of microorganisms has had little effect on growth promotion and yield enhancement of crops

Embodiment 1

[0044] The cultivation of cabbage

[0045] As an experimental group, cabbage seeds immersed in the growth promoter prepared in Preparation Example 1 for 1 hour were sown in a plastic film greenhouse kept at room temperature. Apply 60 milliliters (cc) of the growth promoter remaining after planting to the soil around the roots. After 14 days, the cabbage was cultured for an additional 15 days after an additional application of another 60 ml portion of the growth promoter.

[0046] In addition, as a control group, cabbage was cultured for 15 days under the same conditions except that growth promoters were not used, and seeds were not treated with growth promoters, or were only fertilized with chitosan, garden soil and chicken manure.

[0047] Table 1 shows the weights of cabbage leaves and roots measured after harvesting the experimental group of cabbage grown with the growth promoter and the control group of cabbage grown without the growth promoter, and the total weight of th...

Embodiment 2

[0051] Cucumber cultivation

[0052] As an experimental group, cucumber seeds immersed in the growth promoter prepared in Preparation Example 1 for 1 hour were sown in a plastic film greenhouse kept at room temperature, and cultivated in the same manner as in Example 1 for 15 days.

[0053] In addition, as a control group, cucumbers were cultured for 15 days under the same conditions except that growth promoters were not used, and seeds were not treated with growth promoters or fertilized with only chitosan, garden soil and chicken manure.

[0054] Table 2 shows the weights of cucumber leaves and roots measured after harvesting the experimental group of cucumbers cultured with growth promoters and the control group of cucumbers cultured without growth promoters, and the total weight of crops, respectively.

Embodiment 3

[0058] Cultivation of soybeans

[0059] As an experimental group, soybean seeds immersed in the growth promoter prepared in Preparation Example 1 for 1 hour were sown in a plastic film greenhouse kept at room temperature, and cultivated in the same manner as in Example 1 for 15 days.

[0060] In addition, as a control group, soybeans were cultured for 15 days under the same conditions except that no growth promoter was used, and the seeds were not treated with the growth promoter or fertilized only with chitosan, garden soil and chicken manure.

[0061] Table 3 shows the weights of leaves and roots of soybeans measured after harvesting the experimental group of soybeans grown with the growth promoter and the control group of soybeans grown without the growth promoter, and the total weight of the crops.

Abstract

The invention provides a growth promoter containing microbial agent for inducing composite growth promotion and most effective growth promoting possibility thereby. The microbial agent contains at least two or more PGPR stains selected from soil microbe, and one of them must be a mixture of AP162. Thus, the invention probably overcomes the defects caused by traditional method of random using PGPR strain, such as high cost and low growth promoting effect. In addition, if the growth promoter of the invention is used in cultivation of crops such as cabbage, cucumber, beans, red peppers and tomatoes, the crop of fine variety can be obtained in relative shorter period thereby enhancing marketability and yield and reducing usage amount of fertilizer, thus continuous cultivation can be realized without destroying soil aggregate.

Description

technical field [0001] The present invention relates to a growth promoter prepared by mixing screening strains among PGPR strains isolated from soil, and more particularly to a growth promoter using soil microorganisms capable of, according to the characteristics of corresponding crops, The most effective growth promotion for cultivated crops such as cabbage, cucumber, red pepper and tomato, and a method for cultivating crops using the growth promoter. Background technique [0002] Generally, in most farms, a large amount of chemical fertilizers and agrochemicals are used to achieve continuous crop cultivation and increase in farm crop yields, where farm crops are cultivated using greenhouses and plastic film greenhouses for cultivating high-yield crops. As a result, the soil suffers from extreme deterioration of physicochemical properties, for example, accumulation of various salts, retention of agrochemicals, soil acidification, destruction of soil aggregates, etc., making...
