Description

A kind of prevention and controls of vaccine brown rot

Technical field

The present invention relates to a kind of prevention and controls of vaccine brown rot.

Background technology

Cumquat is also known as golden jujube, golden mandarin orange.Evergreen shrubs.High 3 meters, generally tool does not sting, and sprig is green, and during nutritional sufficiency, branch is many; Leaf lanceolar to oblong, 5-9 centimeter length, Quan Yuan, petiole is wing slightly; Spend little, white, fragrance, 1-3 armpit is raw, petal 5, stamen 20-25, ovary 5 Room; Fruit ellipse or obovate, long 2.5-3.5 centimetre, golden yellow; Genus Japan's cumquat (F.japonica) that fruit is spherical.

Cumquat former distribution coastal area of southeastern China each province, particularly In Guangdong Province, planting and eat the with the longest history of golden mandarin orange, is the township of genuine cumquat.South China and the middle and lower reach of Yangtze River are also widely cultivated in addition.Appreciate its leaf flower, really, or aim at and produce fruit and make tangerine cake person, potted plant rear precision management, breeding grafting, stock trifoliate orange or Citrus seedling.One strain can tie the golden yellow little tangerine of more than 10, and the joyous New Year's Day generally exports Hongkong, welcomes by Hong Kong native very much.Its medical value is higher.

Vaccine brown rot all can occur in field and storing phase, in orchard, when harm kumkwat mandarin tree trunk base portion causes bark to rot, be called " foot rot ", cause during decayed fruit and be generally called " brown rot ", the rainy day that autumn is sultry, often cause orchard to occur serious, cause a large amount of shedding.

Vaccine brown rot cause of disease is that multiple epidemic disease is mould, causes caused by the germs such as the mould Phytophthora citriphora of mainly citrus epidemic disease (sm, the & sm) Lenonian of fruit brown rot.This bacterium generation optimum temperature 25 ~ 28 DEG C, the highest temperature about 32 DEG C, sick fruit is just ash gray round spot, shades gradually, expands, and without depression, keratin, flexible, finger pressure does not break, and has pungent taste after soft corruption.In recent years, the county is along with Planter industry structure adjustment, and cumquat cultivated area increases year by year, and damage by disease and insect occurring area, kind, degree are also corresponding to be increased, and increases the weight of.Vaccine brown rot is the important disease of one of cumquat, and it has a strong impact on cumquat yield and quality.The control of vaccine brown rot is also just most important.

Summary of the invention

The invention provides a kind of prevention and controls of vaccine brown rot.

The invention provides a kind of prevention and controls of vaccine brown rot, step is as follows:

(1), clean orchard

There is more orchard in vaccine brown rot, fruit picking terminates rear combination and prunes, removes to sprout and cover branch, improves ventilation and penetrating light condition, the deadwood shedding of cleaning floor, and shedding is concentrated and burnt, and ground spray bactericide subsequently, to reduce pathogeny;

(2), orchard management is strengthened

Keep without ponding in orchard, garden permeability is good, strengthens water and fertilizer management, the rational application of fertilizer simultaneously;

(3), high-yield orchard supports fruit in time

Sagging subaerial fruit is supported more than 1 meter height with bamboo pole or wooden stick before period of disease, and the fruit propped up can not be overlapping in heaps, should evacuate ventilation; There is vaccine brown rot garden should in time, often treat and process diseased plant, reduce bacterium source;

(4), medical treatment

Onset peak period August ~ November adopts effective agent to spray control;

(5), Scientific Usage of Drugs

Various bactericide can not be reused, in order to avoid vaccine brown rot develops immunity to drugs, answers rotation to use.

Preferably, described in step (4), medicament is: white urea mouth Famoxate 1200-1600 times of liquid, 50% MnZn 500-600 times liquid or 50% metalaxyl-mn-zn 500-600 times liquid.

Apply method of the present invention and can effectively prevent and treat vaccine brown rot, this sick incidence reduces more than 82%.

Embodiment

Following embodiment is convenient to understand the present invention better, but does not limit the present invention.Experimental technique in following embodiment, if no special instructions, is conventional method.Material used in following embodiment, if no special instructions, is commercially available.

embodiment 1

Control vaccine brown rot, should follow the plant protection policy of " putting prevention first, integrated control ".Based on Healthy culture, play the resistance against diseases of kumkwat mandarin tree self.Improve orchard environment, reasonable employment agricultural chemicals.

The prevention and controls step of a kind of vaccine brown rot of the present invention is as follows:

1, clean orchard

There is more orchard in vaccine brown rot, fruit picking terminates rear combination and prunes, removes to sprout and cover branch, improves ventilation and penetrating light condition, the deadwood shedding of cleaning floor, and shedding is concentrated and burnt, and ground spray bactericide subsequently, to reduce pathogeny;

2, orchard management is strengthened

Keep without ponding in orchard, garden permeability is good, strengthens water and fertilizer management, the rational application of fertilizer simultaneously;

3, high-yield orchard supports fruit in time

Sagging subaerial fruit is supported more than 1 meter height, in order to avoid the vaccine in soil splashes on a leaf and fruit through water attack with bamboo pole or wooden stick before period of disease.The fruit propped up can not be overlapping in heaps, should evacuate ventilation.There is vaccine brown rot garden should in time, often treat and process diseased plant, reduce bacterium source;

4, medical treatment

Onset peak period August ~ November adopts effective agent to spray control.Optional with medicament has: white urea mouth Famoxate 1200-1600 times, 50% MnZn 500-600 times or 50% metalaxyl-mn-zn 500-600 times liquid.

5, Scientific Usage of Drugs

Various bactericide can not be reused, in order to avoid vaccine brown rot develops immunity to drugs, answers rotation to use.

Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
