Abstract
The invention discloses a method for controlling eggplant bacterial wilt based on high-school biology experiments. The method comprises the following steps: selecting an anti-bacterial wilt variety according to actual conditions, and performing crop rotation; selecting disease-free seeds and sowing at proper time; removing diseased plants in time to prevent disease spreading, and irrigating disease holes with self-made biopesticide to prevent germ spreading; and in the initial stage of a disease, spraying the biopesticide made by the applicant. Due to the comprehensive control measures, field trials prove that the control effect is better than that of a pesticide group while pesticide residue and environmental pollution are avoided, so that the method is safe and reliable.
Description
Technical field
The present invention relates to the Prevention Technique field of vegetable disease, particularly relate to a kind of method of the control eggplant bacterial wilt based on Senior Biology experiment.
Background technology
Applicant is in conjunction with biological knowledge, according to the requirement of Senior Biology field study, conscientiously careful observation is carried out to the bacterial wilt that the eggplant be planted in oneself vegetable garden occurs, attempt to disclose its regularity of occurrence and development, and utilize the Chinese herbal medicine resource of China's abundant, carry out Biological Control Test, experiment results proved, biological control is Be very effective not only, and non agricultural chemical residuum, Environmental Safety.
Eggplant bacterial wilt their early stage only on indivedual branch one or several sheets leaf look thin out, present local and wither vertical, after expand to whole strain, the later stage, sick leaf browning was dried-up, and sick stem external change is not obvious, as cut disease basal part of stem xylem browning look open.This disease starts from basal part of stem, after extend to branch, the marrow of branch festers or hollow mostly, and sick stem cross section hand extrudes, and has a small amount of milky mucus to overflow during high humidity, and this is this sick key character.Pathogenetic bacteria mainly survives the winter in soil, and next year, with rainwater, irrigation water and soil-borne, invades from host's root or basal part of stem wound, breeds and spread in conduit.Pathogen growth thermophilic 30-37 DEG C, the highest 41 DEG C, minimum 10 DEG C, 52 DEG C lethal through 10 minutes.Germ can survive about 200 days in seed or pin main body, can only survive 2 days, but then can survive 14 months to 6 years in soil once depart from host.Hot and humid is this sick occurrence condition, and soil temperature is often more important compared with temperature.During through observing disease field soil temperature 20 DEG C, germ comes into play, and fragmentary diseased plant occurs, soil temperature 25 DEG C, onset peak appears in field.
Summary of the invention
The object of this invention is to provide a kind of method of the control eggplant bacterial wilt based on Senior Biology experiment.
The object of the invention is to be achieved through the following technical solutions, the method for this control eggplant bacterial wilt comprises the following steps:
(1) suit measures to local conditions to select resistance to bacterial wilt kind.Carry out and Cruciferae or gramineous crop crop rotation in more than 4 years, preferably carry out rice field-upland field rotation.
(2) select disease-free seed, proper seeding, circumvent high temperature season, can morbidity be alleviated.
(3) pull out diseased plant in time, prevent disease from spreading, sick cave is watered homemade biopesticide and prevents proliferation of germs.
(4) their early stage starts to spray the homemade biopesticide of applicant.
The homemade biopesticide of described applicant is made up of the Chinese herbal medicine of following weight portion: Japanses beauty-berry 35 parts, corydalis 46 parts, 40 parts, black flour leaf, 55 parts, cotoneaster 36 Fen, Betel sauce leaf, Centipeda minima 35 parts, flaccid knotweed herb 38 parts.
Preparation method: after taking Japanses beauty-berry, corydalis, black flour leaf, cotoneaster, Betel sauce leaf, Centipeda minima, flaccid knotweed herb pulverizing mixing by above weight portion, divide respectively and add appropriate water for three times and endure 3 times, often all over boiling 2L merging filtrate, and with multilayer gauze and Filter paper filtering, filtrate after heating merges is concentrated into 2L and makes aqua, obtains biopesticide of the present invention.
The characteristic of each Chinese medicine: Japanses beauty-berry has good antibacterial action, has inhibitory action to Escherichia coli, bacterium flexneri, staphylococcus aureus, streptococcus etc.; Corydalis has good inhibitory action to staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa etc.; Black flour leaf all has very strong inhibitory action to staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, shigella flexneri, alpha streptococcus etc.; Cotoneaster has stronger inhibitory action to various bacteria; Betel sauce leaf has obvious inhibitory action to staphylococcus aureus, staphylococcus albus, Escherichia coli, proteus, typhoid bacillus, hay bacillus and some fungi etc., also has significant insecticidal function; Centipeda minima has stronger inhibitory action to bacteriums such as tubercle bacilluses; Flaccid knotweed herb has inhibitory action to various shigella dysenteriae.
Beneficial effect of the present invention: field trial proves, adopts method for integrated control of the present invention, and not only control efficiency is good, and to vegetables without poisoning, noresidue, free from environmental pollution and agricultural product, does not kill natural enemy, have highly effective and safe, the advantage that preventive effect is good.
Field trial data
1, in home, the eggplant that bacterial wilt occurs is being prevented and treated, set up experimental group and control group: when other condition is identical, experimental group adopts biopesticide of the present invention 120 times of liquid spraying controls, control group 40% bacterium crack wetting powder, 600 times of liquid spraying controls, being watered dose is all 35kg/ mu, the eggplant plant of splitting the disease that starts carries out dispenser, uses the spraying of sprayer quantitative and even.
2, within 8 days, start to investigate after investigation content and method dispenser, experimental group and control group respectively investigate 40 diseased plants, and wherein have 38 strains to bring back to life in experimental group 40 diseased plant, 2 strains are dead, and resurrection rate is 95%; Control group is investigated 24 diseased plants in 40 diseased plants and is brought back to life, and 16 diseased plants are dead, and resurrection rate is 60%.Compared with the control, experimental group control efficiency is remarkable for experimental group.
Embodiment
The method of this biological control eggplant bacterial wilt comprises the following steps:
(1) suit measures to local conditions to select resistance to bacterial wilt kind.Carry out and Cruciferae or gramineous crop crop rotation in more than 4 years, preferably carry out rice field-upland field rotation.
(2) select disease-free seed, proper seeding, circumvent high temperature season, can morbidity be alleviated.
(3) pull out diseased plant in time, prevent disease from spreading, sick cave is watered the homemade biopesticide of applicant and prevents proliferation of germs.
(4) their early stage starts to spray the homemade biopesticide of applicant.Described biopesticide of the present invention is made up of the Chinese herbal medicine of following weight portion: Japanses beauty-berry 350 grams, corydalis 460 grams, 400 grams, black flour leaf, 550 grams, cotoneaster 360 Ke, Betel sauce leaf, Centipeda minima 350 grams, flaccid knotweed herb 380 grams, after pulverizing mixing, the water adding 18L, 10L, 10L respectively endures 3 times, often all over boiling 2L merging filtrate, and with multilayer gauze and Filter paper filtering, filtrate after heating merges is concentrated into 2L and makes aqua, obtains biopesticide of the present invention.
