Embodiment 1

[0054] Example 1: Effect of Selected Trichoderma Strains

[0055] In this example, pot experiments were performed to show that selected Trichoderma microorganisms can increase the efficiency of organic fertilizers. Sandy loam was used as potting substrate, tomato (Lycopersiconesculentum) was used as test plant, and compost was used as organic fertilizer (0.5% w / w). The size of the flower pot is: both diameter and height are 10 cm. Four doses (i.e., 10 1 、10 4 、10 6 and 10 7 CFU / g soil, expressed as doses 1, 2, 3 and 4) Trichoderma microorganisms were added to the potting mix. Soil control samples were uninoculated seedlings where only organic fertilizers were used.

[0056] Measure plant biomass at harvest (38 days) in the form of root dry weight and shoot dry weight, as Figure 1A and Figure 1B shown. according to Figure 1A , the plant biomass in the roots of inoculated seedlings (doses 2, 3 and 4) was significantly greater than the plant biomass in the roots of uni...

Embodiment 2

[0058] Example 2: Effect of microbial blends

[0059] In this example, pot experiments were performed to show that a selected microbial blend comprising Bacillus polymyxa, Bacillus subtilis, Trichoderma harzianum, and Saccharomyces cerevisiae was able to increase the efficiency of organic fertilizers. Sandy loam was used as potting substrate, tomato (Lycopersiconesculentum) was used as test plant, and compost was used as organic fertilizer (0.5% w / w). The size of the flower pot is: both diameter and height are 10 cm. Three doses (i.e., 10 2 、10 3 and 10 4 CFU / g soil, expressed as doses M1, M2 and M3, respectively) of the microbial blends were added to the potting mix. Control samples (Ctrl) were uninoculated seedlings where only organic fertilizers were used.

[0060] Plant height, canopy, stem size and chlorophyll index were measured on day 41 and recorded in Tables 1 to 4 as Figures 2A to 2D shown. according to Figure 2B , the canopy of inoculated seedlings (M1, M2...

Embodiment 3

[0070] Embodiment 3: the effect of microbial activator on Trichoderma bacterial strain

[0071] In this example, Trichoderma microorganisms supplemented with different microbial activators were applied to tomato seedlings in pot experiments to demonstrate the efficacy of the microbial activators. The experimental setup was similar to that described in Example 1. Table 5 summarizes the composition of the various activator formulations administered in this example, which included yeast autolysate, humus powder, and micronutrients with amino acids.

[0072] The composition of the activator preparation of table 5 Trichoderma

[0073]

[0074] Measure plant height, stem size, shoot dry weight, and root dry weight on day 35 as Figures 3A to 3D shown. As shown in the figure, microorganisms supplemented with yeast autolysate, humus powder and / or micronutrients (treatment numbers P0, P2-0.2, P3-8) were compared with plants treated with microorganisms alone (treatment number P0)....

Abstract

A plant growth promoting composition includes beneficial microbes and microbial activators. The beneficial microbes may include Bacillus spp., Azotobacter spp., Trichoderma spp., Saccharomyches spp., or combinations of these, the microtrial activators include enzymes, metabolites, carbohydrate yeast, humic material, staich, amino acids and micornutrients. The plant growth promoting composition may also include organic and inorganic fertilizers.

Description

[0001] This application claims to submit on June 20, 2007, the serial number is No. 60 / 945,149, and the invention title is "Microbial Formulation and Method of Using the Same to Promote Plant Growth (microbial formulation and method for promoting plant growth using it)" priority of the US provisional application, the contents of which are incorporated herein by reference. Background technique [0002] In agriculture, fertilizers are used in excess worldwide to provide nutrients that support plant growth. Although chemical fertilizers have provided benefits to modern agriculture, a decrease in the texture and quality of agricultural soils has been observed due to increasing use of chemical fertilizers. Excessive use of chemical fertilizers has led to soil compaction and erosion, and has resulted in lower yields and less efficient use of fertilizers. Therefore, the sustainable use of agricultural land has received special attention, as has the excessive use of chemical fertiliz...
