Embodiment 1
[0039] A kind of Quercus plant root-promoting microorganism microcapsule inoculant agent, and its components include: 10% of rhizobium radiata liquid, 10% of Bacillus megaterium liquid, 10% of seawater Bacillus liquid, jelly-like spore-like bacteria Bacillus liquid 10%, white carbon black 20%, corn starch 20%, gum arabic 8%, trehalose 4%, skimmed milk powder 3.9%, glycerin 4%, sodium naphthalene acetate 0.1%; The number of effective viable bacteria in the bacillus liquid, seawater bacillus liquid and jelly-like Paenibacillus liquid was 1.38×10 10 cfu / g, the number of miscellaneous bacteria is 3.28%.
[0040] Obtained by the following preparation method:
[0041] 1) Preparation of seed liquid: Rhizobia radiata, Bacillus megaterium, Bacillus marinum, and Paenibacillus jelly-like were respectively inoculated in the corresponding seed medium, cultured on a shaker at 30°C and 200r / min for 12 hours, and prepared into seed liquid ;
[0042] 2) Fermentation: Put the seed liquid pre...
Embodiment 2
[0049] The field application experiment of embodiment 2 microbial microcapsule bacterial agents:
[0050] Select 1m in the planting field for planting A. microphylla, A. spp. 2 There are 12 plots, which are divided into 4 groups on average, and there are 60 seedlings per square meter. Among them, three groups were respectively applied with Qifu EM planting strain, TMF bacterial agent, and the microbial microcapsule bacterial agent prepared in Example 1, and the remaining group did not apply any bacterial agent as a control. The four groups of sample plots had the same treatment conditions and grew for six months. After that, 10 experimental seedlings were randomly selected in each plot to measure the height and dry biomass of the experimental seedlings, and the root system was scanned, and the root length, surface area, diameter, and number of root tips were counted, and the average was calculated. The results are shown in Table 1.
