Description
Technical field
The present invention relates to pesticides, bleeding disease Prevention Technique field, and in particular to a kind of prevention and treatment large cherry tree bleeding disease is killed
Microbial inoculum and preparation method thereof.
Background technique
Large cherry is a kind of rosaceae, cherry, and northern China deciduous fruit tree relays fruit maturation after cherry
Earliest fruit tree species.Traditional Chinese medicine and pharmacy thinks that large cherry has tonifying Qi in tune, the function of wind-damp dispelling.The gorgeous delicious, battalion of large cherry color
Abundant, morning in maturity period is supported, is to list earliest, most effective fruit in northern deciduous.In recent years, large cherry was in suitable planting area
It is rapidly developed, but often occurs dead tree phenomenon in production, bring greater loss to orchard worker, and because of stream in various diseases
Glue disease and the phenomenon that extremely setting it is the most serious.
Large cherry bleeding disease is a kind of important disease of cherry, and symptom is divided into two kinds of dry rot type and ulcer type gummosis.It is dry
Rotten type mostly occurs on trunk, major branch, and initial stage scab is irregular, is in crineous, surface is hard, Chang Yinfa gummosis, later period scab
In long strip type, drying shrinkage recess, surrounding cracks sometimes, the dense pore in surface.Ulcer type bleeding disease, sick portion's tree body have resin raw
At, but do not flow out, and retain between xylem and bast, the sick micro- protuberance in portion, flowed with sap immediately, from sick portion's hole skin or
Wound outflow.Sick portion is just colourless slightly transparent or crineous, hard.
There are many reason of causing large cherry tree bleeding disease, to sum up there is the reason of following aspect: 1. anvil fringes are not affine, certain
The large cherry bleeding disease performance of a little stock graftings is serious；2. edaphic condition is not suitable for large cherry growth, in clayed soil or saline and alkaline
Ground bleeding disease is serious；3. root diseases, if there is crown gall, Root―rot disease, root rot or because ponding causes root system in big cherry root
It is weak to be also easy to produce bleeding disease；4. being caused by fungal infection, i.e., caused by grape seat chamber bacterium and peach capsule embrace bacterium dip dyeing.Pathogen is with bacterium
Filament and pycnidia are overwintering in the diseased tissue of trunk, branch, and second year generates a large amount of mitogenetic spores before and after cherry rudiment
Son borrows wind and rain to propagate, and invades from wound or hole skin, can infect repeatedly later.High humidity is the essential condition that disease occurs, and spring is low
Warm more wet weather easily cause trunk to be fallen ill, and the rainy season of high temperature and humidity is morbidity peak period, until the 9-10 middle of the month slowly stops.It is rainy season, special
It is not to drop heavy rain after prolonged drought, bleeding disease is more serious；5. being caused by bacterial disease, large cherry Bacterial septicaemia syndrome occurs tight
Weight, leaf diseases infect limb, cause water stain shape necrotic plaque, expand and deeply generate gummosis, limb scab with necrotic plaque
It is the main source of infection of second year leaf diseases；6. making part bark death cause gummosis since freeze injury or day burn.
It will thus be seen that large cherry tree bleeding disease reason is complicated, multiple means of prevention integrated treatment need to be used.And it is existing anti-
The technology of controlling mostly uses medicament to smear and spray, and not only operation sequence is more, and artificial and time cost is higher, and there is chemical agriculture
The harm of chemicals contamination.
The primary medicinal component of Chinese scholartree seed is rutin, and content reaches 24% or so, and the antibacterial ability of rutin is by very
More research institutes confirm that therefore, it is raw material that Chinese scholartree seed, which can be used, in we, inhibit pathogen growth using its rutin content abundant, subtract
Lack gummosis.
Chitin also known as chitin, chitin, the structure homopolysaccharide being polymerized for N-acetyl-glucosamine by β connection.
It is widely present in the cell wall of the shell of shellfish, the crust of insect and fungi.It is in purposes agriculturally are as follows: 1. crusts
Plain (chitosan) can induce crop to obtain systemic anti pathologic immunity power, the resisting substances such as chitinase be generated, to support for a long time
Resist various diseases；2. after chitin is manured into soil, can cultivate the profitable strains such as a large amount of actinomyces, these profitable strains improve
A large amount of antibiotic agents and resistance enzyme chitinase for secreting out of while soil etc., can directly dissolve nematode and its worm's ovum body
Wall, while inhibiting the growth and breeding of pernicious bacteria；3. chitin (chitosan) has and powerful take root, supports root effect and can promote root
It is the division of cell, makes capillary root increasing fast, promotes well developed root system；4. chitin is drenched into root, attachment film forming protects root
System, prevents root-rot black root rotten.And shrimp and crab shells are rich in chitin, therefore, can be induced by chitin ingredient in broken shrimp and crab shells
The prevention and treatment mechanism of plant against fungal venereal disease evil.
In conclusion we can be using Chinese scholartree seed as raw material, shrimp and crab shells powder is that auxiliary material combines to reach prevention and treatment large cherry
Set the purpose of bleeding disease.
Summary of the invention
It is an object of the present invention to provide a kind of fungicide for preventing and treating large cherry tree bleeding disease, can effectively inhibit harmful

It can be seen that from the test result of table 1
Because any fungicide, aggravation after test is not used in blank group, cure rate is -8.3%, embodiment 1-3
Cure rate reached 93% or more；Because lacking Chinese scholartree seed powder and shrimp and crab shells meal component respectively in comparative example 1,2, after test
Cure rate is respectively 44.7% and 51.2%；Lower water temperature in comparative example 3,4 because respectively walking second, third in preparation method
It is -5 DEG C, the cure rate after test is respectively 75.5% and 77.8%；In comparative example 5,6 because respectively by second in preparation method,
The lower water temperature of third step is 50 DEG C, and the cure rate after test is respectively 27.5% and 20.2%；Because respectively will in comparative example 7,8
The pH value adjustment of the 4th step is 6.0 and 9.0 in preparation method, and the cure rate after test is respectively 7.2% and 8.7%.
It follows that in the present invention Chinese scholartree seed powder and shrimp and crab shells meal component combine can reach effectively prevent large cherry tree stream
The purpose of glue disease, and the preparation method of this fungicide is the method that is most suitable for, large cherry tree stream can be reduced by changing temperature or pH value
The cure rate of glue disease.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can also make several improvements and retouch, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
