Problems solved by technology

[0005] However, due to the characteristics of rapid growth, reproduction and rapid variation of microorganisms, the root-promoting performance of growth-promoting bacteria may degrade, and the use of growth-promoting bacteria is also limited by regional, crop types, and environmental conditions. The screening of strains that provide crops with a large amount of trace elements or have growth-promoting functions for crops, such as dissolving potassium, is an important work at present.

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.

Abstract

The invention provides an oak plant root-promoting microbial microcapsule inoculant and a preparation method thereof. The active ingredients of the microbial microcapsule inoculant are rhizobium radiobacter, bacillus megaterium, bacillus marinus and paenibacillus mucilaginosus, and the microbial microcapsule inoculant is long in normal-temperature storage time and high in thallus survival rate andcan promote growth of roots and tips of oak plants; the microbial microcapsule inoculant is prepared by adopting a spray drying technology, and the production process is reasonable in design, so thatthe cleanliness and sterility of the inoculant are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of bio-organic fertilizers, and in particular relates to a microcapsule agent for root-promoting microorganisms of Quercus plants and a preparation method thereof. Background technique [0002] The broad genus Quercus Fagaceae includes subgenus Cyclobalanopsis and subg Quercus, which are widely distributed in tropical, subtropical and temperate forests in northern hemispheres such as Asia, Africa, Europe and America, and many of them are still There are about 600 main constructive and dominant species in forests in the northern hemisphere, and 127 species in China. In the past, people’s research on Quercus species mainly focused on economic value, such as wood utilization and fruit utilization. In recent years, with the improvement of the quality of urban greening, some native tree species and foreign newly introduced tree species have gradually appeared in urban green spaces. more abundant. At this stage,...
