Problems solved by technology

[0002] Citrus canker is a disease caused by Trichobacterium flavus, which mostly occurs in citrus. The disease damages citrus leaves, branches and fruits. When the seedlings and young trees are seriously damaged, it will cause fallen leaves and dead shoots, which will affect the tree vigor; the fruit will be severely damaged. The fruit will drop, and the light one will have disease scars, which will not tolerate storage and rot, which will greatly reduce the commodity value of the fruit, increase the cost of disease and pest control for the fruit grower, and damage the economic benefits.
[0003] At present, P. flavus is usually controlled by spraying pesticides on citrus leaves. However, on the one hand, pesticides can easily make pathogenic bacteria resistant and reduce the difficulty of control; on the other hand, they will pollute the environment.

Embodiment 1

[0024] Example 1 Screening of Bacillus polymyxa LTPP03

[0025] 1) Sample collection: collect soil (forest land in Sitang Town, Xingning District, Nanning City) and put it in a container;

[0026] 2) Dilution and heating in a water bath: Take 10 g of soil and put it into a 250 ml beaker, add 90 ml of sterile water into the beaker, oscillate to make a concentration of 10 -1 Soil dilution A; place soil dilution A in a water bath at 80°C and heat for 10 minutes;

[0027] 3) Gradient dilution:

[0028] (1) Take 3 test tubes filled with 9mL sterile water and mark them as: 10 -2 、10 -3 and 10 -4 ;

[0029] (2) Shake the soil dilution A, rest for 30 s, pipette 1mL of the soil dilution and add to the marked 10 -2 In the test tube, gently blow and suck several times in the test tube to make it fully mixed, and then obtain the soil dilution B;

[0030] (3) Similarly, draw 1mL of soil dilution B and add the number 10 -3 In a test tube, blow and suck and mix to obtain soil dilutio...

Embodiment 2

[0042] Example 2 Identification of Bacillus polymyxa LTPP03

[0043] The China Center for Type Culture Collection identified the Bacillus polymyxa LTPP03 strain on February 28, 2019. Identification includes morphological observation of Bacillus polymyxa LTPP03 strain, physiological and biochemical characteristics test, determination and analysis of 16SrRNA gene sequence, and the taxonomic status of the strain is determined according to the identification results. The strain was identified as: Bacillus polymyxa LTPP03 ( Paenibacillus polymyxa LTPP03). The test results of physiological and biochemical characteristics are shown in Table 1-Table 2;

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a water-soluble Bacillus polymyxa fertilizer and its preparation method and application. Background technique [0002] Citrus canker is a disease caused by Trichobacterium flavus, which mostly occurs in citrus. The disease damages citrus leaves, branches and fruits. When the seedlings and young trees are seriously damaged, it will cause fallen leaves and dead shoots, which will affect the tree vigor; the fruit will be severely damaged. The fruit falls, and the light one has disease scars and cannot be stored, and rots, which greatly reduces the commodity value of the fruit, increases the cost of disease and insect pest control for the fruit grower, and damages the economic benefits. [0003] At this stage, P. flavus is usually controlled by spraying pesticides on citrus leaves. However, on the one hand, pesticides are likely to make pathogenic bacteria resistant an...
