Description
Technical field
The present invention relates to one kind to belong to agricultural plant protection technical field, and in particular to a kind of to utilize photosynthetic film prevention and control mandarin orange high in fat
The method of tangerine yellow twig diffusion.
Background technique
Citrus is the important industrial crops in China.It is the main source in the torrid zone, subtropical zone orchard worker increase income all the time.
It is well known that Citrus Huanglongbing pathogen is the destructive disease on world's Orange Producing.It is withered in 1-2 after the onset of nursery stock and earsh
Extremely, bearing capacity is lost after the onset of bearing tree in 3-5.This disease will lead to the reduction of large area yield, and quality deteriorates,
Even dead, this brings to the economic value of citrus and greatly loses, and the income of farmer has been seriously affected, for this purpose, clearly
It the understanding Citrus Huanglongbing pathogen evil of Chu and takes effectively measure to be prevented and treated to be the largest harvest for farmer.It is current anti-
Controlling method mainly has stringent quarantine system, prevents sick seedling anthropochory, cultivates disease-free nursery stock, microbial control, and prevention and treatment cause of disease passes
Broadcast medium --- the methods of diaphorina citri.However the use process of these methods has itself limiting factor, occurs preventing and treating
Loophole, so that Citrus Huanglongbing pathogen evil occurs in the equal large area of different zones every year.
Summary of the invention
The present invention is intended to provide a kind of method using photosynthetic film prevention and control Citrus Huanglongbing pathogen diffusion high in fat, can effectively reduce
Huanglong germ infects harm to citrus.
The present invention provides a kind of method using photosynthetic film prevention and control Citrus Huanglongbing pathogen diffusion high in fat, including photosynthetic high fat film
Agent, the photosynthetic film high in fat is by weight composed of the following components: 100 parts of lauryl alcohol, 10 parts of emulsifier, helps 200 parts of hexadecanol
6 parts of emulsifier, 50 parts of thickener, 800 parts of water；After being diluted with water using the photosynthetic film high in fat, in citrus tender slightly phase, bud
Phase, small fruiting period, fruit expanding period, maturity period, are sprayed mandarin tree, include the following steps:
A1: the tender slightly phase, after photosynthetic film high in fat is diluted with water 200 times, whole strain was carried out every 7 days spraying one at age tree
It is secondary；

It is melted to 60 degree, emulsifier and assistant for emulsifying agent is added in container, passes through high-shear homogenizing machine homogenization, revolving speed 5000
Rev/min, it rotates 10 minutes, 800 parts of water of 60 degree is added in container, pass through high-shear homogenizing machine homogenization, revolving speed
It 10000 revs/min, rotates 10 minutes, is cooled to 40 degree, thickener is then added in container, it is equal by high-shear homogenizing machine
Matter processing, with 10000 revs/min rotate 30 minutes after to get.
The present invention has the advantages that compared with traditional planting technology
1, it is simple and efficient.In each period of Ci trus growth, prepares photosynthetic membrane aqueous solution and mandarin tree is sprayed, it can
Increase plant photosynthetic rate, plant immunity is provided, can more effectively reduce the invasion of Huanglong germ, play growth-promoting insect prevention diseases prevention
Effect, easy to operate, saving of work and time.
2, high yield and high quality.Though this photosynthetic membrane is free of minerals (N, K, P, Fe, Zn, Mg ...) nutrients, photosynthetic membrane can be mentioned
High photosynthate (CH2O), therefore enable higher yield of crops, high-quality.Though this photosynthetic membrane is not pesticide, do not have bactericidal properties (nothing
Poison), but physics film layer can reach insect prevention diseases prevention (biological infectious disease and non-infective disease) and volume increase purpose.Though this photosynthetic membrane is not raw
Long element is not belonging to stimulating growth or inhibits the chemicals of growth, but film layer can inhibit moisture transpiration or evaporation, have water conservation,
Heating effect, therefore be conducive to vine growth and development, volume increase increases income again.
3, environmental protection and public nuisance free.After " photosynthetic membrane ", the use of chemical fertilizer and pesticide can be substituted or reduced.Because of its insect prevention
Diseases prevention is physical action, and germ will not develop drug resistance, itself is nontoxic, harmless, nontoxic to people, plant, fish, is a kind of " nothing
Public hazards " pesticide.
Embodiment 2
Biological Effects
Refer mainly to two aspects, i.e. insect prevention, protection effect.By photosynthetic membrane in Shaoguan Qujiang District, Renhua County and Shixing County etc.
The enterprising prevention and treatment pest and disease damage of citrus experiment, control group pesticide, wherein insecticide is avermectin effective cypermethrin,
Fungicide is Prochloraz, is bought respectively from market, and usage illustrates use according to Product labelling.Experiment effect is as follows:
1 photosynthetic membrane of table pest control effect on citrus
| Experimental group | Control group | |
| Phyllocnistis citrella stainton control efficiency (%) | 88.2 | 58.8 |
| Diaphorina citri control efficiency (%) | 85.1 | 67.8 |
| Citrus red mite control efficiency (%) | 86.6 | 68.9 |
Calculation formula are as follows:
In formula:
PT --- control efficiency, unit are percentage (%)
PT0--- borer population before chemicals treatment district medicine, unit are head；
PT1--- borer population after chemicals treatment district medicine, unit are head；
CK0--- borer population living before blank district application, unit is head；
CK1--- borer population living after blank district application, unit is head.
2 photosynthetic membrane of table disease-controlling effect on citrus
| Experimental group | Control group | |
| Citrus anthracnose control efficiency (%) | 90.5 | 82.8 |
| Citrus bacterial canker disease control efficiency (%) | 87.6 | 77.7 |
| Citrus fuliginous control efficiency (%) | 90.4 | 76.9 |
Calculate publicity are as follows:
Investigation method: every cell investigates two plants, every plant by 5 points of samplings in all directions, every 10 fruits of investigation and two
Whole blades on the tip.Leaf (fruit) stage division:
0 grade: disease-free；
1 grade: every leaf (fruit) has scab 1-5；
3 grades: every leaf (fruit) has scab 6-10；
5 grades: every leaf (fruit) has scab 11-15；
7 grades: every leaf (fruit) has scab 16-20；
7 grades: every leaf (fruit) has scab 21 or more.
From table 1 it follows that photosynthetic membrane is to tested several pest phyllocnistis citrella staintons, diaphorina citri and citrus red mite
Control efficiency be substantially better than control group；It can be seen that photosynthetic membrane is to tested several disease citrus anthracnoses, citrus from table 2
Canker and the control efficiency of Citrus fuliginous are also superior to control group.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
