preparation example Construction

[0023] refer to figure 1 Shown, the embodiment of the present invention provides a kind of preparation method of microbial composite preparation, comprises the following steps:

[0024] S1, the actinomycetes, nitrogen-fixing bacteria, photosynthetic bacteria, nitrate bacteria, lactic acid bacteria, yeast bacteria, phosphorus-dissolving bacteria and growth bacteria according to the mass ratio of 13.8-14.3:8.3-8.8:15.8-16.3: 7 to 7.5: 17.7 to 18.2: 15.8 to 16.3: 7.5 to 8.0: 12 to 13 Mix evenly to form a microbial composite preparation.

[0025] As a further improvement, in step S1, preferably, the actinomycete group, the nitrogen-fixing bacteria group, the photosynthetic bacteria group, the nitrate bacteria group, the lactic acid bacteria group, the yeast group, the The mass ratio of the phosphate-dissolving bacteria group and the growth bacteria group is: 14:8.5:16:7.3:18:16:7.7:12.5.

[0026] The embodiment of the present invention also provides a microbial composite prepara...

Embodiment 1-1

[0027] Embodiment 1-1: Actinomycetes, nitrogen-fixing bacteria, photosynthetic bacteria, nitrate bacteria, lactic acid bacteria, yeast flora, phosphate-dissolving bacteria and growth flora according to mass ratio 14:8.5:16:7.3: 18:16:7.7:12.5 Mix evenly to form a microbial composite preparation. Take water spinach as the test vegetable, carry out soil cultivation, and apply the microbial compound preparation, the average culture temperature is 25±2°C, measure the plant growth of each treatment group 30 days after the emergence of water spinach seedlings, test 3 groups of parallel experiments, and take the average value.

Embodiment 1-2

[0028] Example 1-2: The actinomycetes, nitrogen-fixing bacteria, photosynthetic bacteria, nitrate bacteria, lactic acid bacteria, yeast bacteria, phosphate-dissolving bacteria and growth bacteria according to the mass ratio of 13.8:8.3:15.8:7: 17.7: 15.8: 7.5: 12 Mix evenly to form a microbial composite preparation. Take water spinach as the test vegetable, carry out soil cultivation, and apply the microbial compound preparation, the average culture temperature is 25±2°C, measure the plant growth of each treatment group 30 days after the emergence of water spinach seedlings, test 3 groups of parallel experiments, and take the average value.

Abstract

The invention provides a preventing and treating method for citrus tristeza virus. The method comprises the following steps: S4, carrying out spraying and root-irrigation of a diluted biological plantprotection agent every 48-96 hours to citrus and carrying out root-irrigation and tree washing of the diluted plant protection agent, applying an efficient organic fertilizer and a liquid fertilizerat the same time, and carrying out operations continuously for 2-4 hours; S5, carrying out spraying and root-irrigation of the diluted biological plant protection agent every 10-20 days, and carryingout root-irrigation and tree washing of the diluted plant protection agent at the same time; and S6, fully spraying the diluted biological plant protection agent every one month finally and carrying out root-irrigation of the diluted biological plant protection agent at the same time.

Description

technical field [0001] The invention relates to a method for preventing and treating citrus huanglongbing. Background technique [0002] Citrus huanglongbing is a devastating disease in citrus planting industry, also known as green fruit disease, withered yellow disease, and yellow shoot disease. The source of pathogenic bacteria is formed mainly through citrus-carrying seedlings, fungus-carrying scions or citrus-carrying psyllids, and then spreads in a large area during the period when citrus branches sprout, and then causes major disasters to citrus production. It has become the main factor restricting the sustainable and healthy development of my country's citrus industry . Citrus Huanglongbing is a devastating citrus disease caused by bacteria of the genus Phloembacterium. Traditional citrus Huanglongbing control methods mainly use chemical insecticides to kill the vectors, resulting in soil pollution and fertility decline. Contents of the invention [0003] The inve...
