Wherein, the deposit number for the bacillus licheniformis (Bacillus licheniformis) that this programme uses are as follows:14580D-5TM, the strain is purchased from American Type Culture collection warehousing (American type culture Collection, ATCC), it is bacillus licheniformis type culture (Bacillus licheniformis (Weigmann) Chester);
The deposit number for the bacillus megaterium (Bacillus megaterium) that this programme uses are as follows: 14581TM, which is purchased from ATCC, for bacillus megaterium type culture (Bacillus megaterium de Bary);
The deposit number for the bacillus pumilus (Bacillus pumilus) that this programme uses are as follows:7061TM, should Strain is purchased from ATCC, is bacillus pumilus type culture (Bacillus pumilus Meyer and Gottheil);
The deposit number for the bacillus cereus (Bacillus cereus) that this programme uses are as follows:14579D- 5TM, it is bacillus cereus type culture (Bacillus cereus Frankland and which, which is purchased from ATCC, Frankland);
The deposit number for the colloid bacillus cereus (Bacillus mucilaginosus) that this programme uses are as follows: 10792TM, it is colloid bacillus cereus type culture (Bacillus mucilaginosus which, which is purchased from ATCC, Berliner)。
The beneficial effect of the technical program is specific as follows:
(1) stimulation Queensland nut fruit tree main root increases, so that root system is grown to deep subsoil
Auxin secretion, transport and the distribution of the controllable Queensland nut fruit tree root of the bacteria agent composition of this programme, To stimulate fruit tree root to grow to deep subsoil, fruit tree is set to absorb the moisture and nutrient of deep subsoil, simultaneously Since the depth of root is pricked, the wind loading rating of fruit tree is further strengthened, to improve the ability that fruit tree adapts to environment.
Queensland nut fruit tree main root is undeveloped, and main root system is distributed in soil shallow layer.At the florescence in spring of arid, fruit tree Moisture and nutrient can not be obtained from deep soil for growth of young;Since Root Distribution is shallow, wind resistance is weak for fruit tree, encounters strong Wind can be such that adult fruit tree covers, to cause production loss.The prior art, which is generally used, applies plant growth regulating into soil The method of substance, to stimulate fruit tree root growth, such as exogenous auxin, gibberellin.The scheme of the prior art is lacked there are various Point.Disadvantage one is excessive to lateral root growth stimulation.Growth regulatory substance promotes the development of lateral root and main root simultaneously, due to side Radical amount is more and distribution is shallower, and the inducing action that growth regulatory substance compares main root to the inducing action of lateral root is stronger, this is just Main root is caused to increase few, but lateral root raised growth.In the limited orchard in space, due to the raised growth of lateral root, fruit tree It influences each other between lateral root, the common nutriment for competing shallow-layer, also resulting in that fruit tree nutrition is bad or dose increases etc. asks Topic.Root system largely develops in soil shallow-layer, and certain difficulty can be also caused to ditching-fertilizing because trench digging need to avoid root it is intensive Region to reduce the damage of mechanism and the excessive fertilizer of concentration to root.Disadvantage two is to have to main root growth stimulation Limit.Main root increment can not enough solve Queensland nut fruit tree wind loading rating difference very well and cannot make full use of deep subsoil The problem of nutrition.Disadvantage three is that action time is too short.Although growth regulatory substance can snap action, acting duration compared with It is short, it needs repeatedly to apply often application, is just able to maintain its stimulation to root growth.Disadvantage four is environmental pollution.Excessive Can also ecological environment be caused centainly to negatively affect by applying artificial growth regulatory substance.
The technical program can solve more than technical problem.The microbial bacterial agent composition of this programme may act on Australia Nut fruit tree endogenous growth hormone synthesis secretion access, can be synthetically produced slight inhibiting effect to endogenous growth hormone.Plant Root is more sensitive to growth hormone, and the growth hormone of low concentration can promote the growth of root, the growth hormone pair of higher concentration The growth of root shows as inhibiting effect.The growth hormone of the cell of tip of a root root cap area and meristematic zone synthesis, under gravity Transport lower part in position into root system, causes the growth hormone accumulated in main root meristematic zone and elongation zone more, right The growth of main root produces inhibiting effect, and amount of the growth hormone at lateral root position is less, is just suitble to the growth of lateral root.This programme Microbial bacterial agent composition slightly inhibit the synthesis of Endogenous auxin so that the auxin that accumulates in main root is reduced, generate Certain promotion main root growth.It being reduced since endogenous growth hormone synthesizes, the level of growth hormone of lateral root part reduces, Growth hormone also decreases the stimulation of lateral root, and the level of growth of lateral root is controlled in a certain range.
(2) mitigate disease, reduce pesticide residue
Various bacillus, which breed rapidly, after microbial bacterial agent composition is manured into soil, in this composition becomes dominant bacteria, The nutrition and other resources for controlling root system, cause pathogen to lose living space and condition.Various gemma bars in this composition The secondary metabolite of bacterium improves fruit tree epiblem cell wall thickening, fibrosis, degree of lignification, strengthens the diseases prevention of fruit tree Harmful ability.The prior art handles the fruit diseases of Queensland nut usually using pesticide, has to environment a degree of broken Bad effect, and pesticide can also stimulate harmful microorganism to generate drug resistance.The technical program overcomes the defect of the prior art, Has the function of biological control.
(3) fertilizer efficiency is improved
The bacteria agent composition of this programme can decompose the organic matter in soil or fertilizer, and the organic matter after decomposition is conducive to Fruit tree absorbs, the utilization rate of increased fertilizer or nutriment.The microbial bacterial agent composition of this programme can also synthesize secretion The nutriments such as unavailable phosphorus, calcium, magnesium are converted into available state, further mentioned by a variety of organic acids, enzyme, physiological activator etc. High utilization of nutrients.
Further, the microbial bacterial agent comprises the following steps:
Step a: by bacillus licheniformis, bacillus megaterium, bacillus pumilus, bacillus cereus and colloid gemma Bacillus is expanded respectively connects big cultivation and fermentation, obtains 5 kinds of zymocyte liquids;
Step b: separation obtains 5 kinds of thallus respectively from 5 kinds of zymocyte liquids in step a, and 5 kinds of thallus are abundant in proportion It mixes, obtains Mixed Microbes;
Step c: the Mixed Microbes in step b are expanded culture, mixed bacteria liquid is obtained;
Step d: separation obtains mixing thallus from the mixed bacteria liquid in step c, by mixing thallus drying to get described micro- Bacteria agent composition.
By adopting the above technical scheme, by 5 kinds of single bacteriums carry out expand connect cultivation and fermentation after so that 5 kinds of bacillus numbers and work Property increase;Then according to the ratio of 2-3:1-2:1-2:2-3:3-5 (mass ratio) by bacillus licheniformis, bacillus megaterium, Bacillus pumilus, bacillus cereus and the mixing of colloid bacillus cereus thallus;Mixed bacillus connects culture by expansion Microbial bacterial agent composition of the invention can be made with drying.
Further, a kind of preparation method of Queensland nut special bio bacterial manure, by regulation proportion by microbial bacterial agent, organic Fertilizer, nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, middle trace element fertilizer, humic acid, plant growth-promoting substance, bentonite are thoroughly mixed uniformly;? At 25-30 DEG C of temperature and pH 6.0-6.8, screened and drying is made.
