Abstract
The invention relates to the field of agriculture planting and discloses a clubroot control method. The method comprises the steps of planting Chinese cabbage in soil containing clubroot pathogenic bacteria, pulling up the Chinese cabbage by the roots after the Chinese cabbage is in a vigorous growing period, and then planting another kind of cruciferae vegetable in the soil, wherein the Chinese cabbage is at least one of Luchunbai 83-1, Huangxinbai, Chunxi04-2 and Chunxi zaohuangbai. The method can effectively and greatly reduce the incidence of cruciferae clubroot in soil containing clubroot pathogenic bacteria, and has an important significance in controlling cruciferae clubroot and increasing yield.
Description
Technical field
The present invention relates to field of agricultural cultivation, in particular it relates to a kind of method of prevention and control clubroot.
Background technology
Cruciferae clubroot is to infect the soil-transmitted disease of crop in cruciferae, and its pathogen is flagellum
Bacterium subphylum plasmodiophora brassica bacteria (Plasmodiophora brassicae Woronin).In China, main harm is big
The crop in cruciferae such as Chinese cabbage, green vegetable, Brassica oleracea L. var. botrytis L., Caulis et Folium Brassicae junceae, Radix Raphani, Brassica campestris L, Maca, crop is being subject to
After infecting to plasmodiophora brassicae, form not of uniform size, the smooth or coarse tumor that chaps at root, cause cross
Flower section's vegetable root and stem Assimilation and conductivity nutrient is obstructed, undergrowth, wilt, downgrade, yield and quality are subject to
Damage, so that the underproduction, cause economic loss, be one of the Major Diseases of crop in cruciferae.Clubroot master
The modes such as bacterium is native, old complaint is thrown out without care are carried by dish strain band vaccine, current by the resting spore in soil
Propagating, acidity or the moist beneficially pathogenic bacteria of soil sprout and invade harm.
The method that the method for prevention and control clubroot generally uses Synthetical prevention at present, specifically includes that
Carry out plant quarantine measure, block epidemic-stricken area；In conjunction with deep ploughing, carry out crop rotation；At cleaning old complaint inoculation
Reason；Appropriate pool liming (soil acidity loose using, what soil stickiness hardened should not use)；
Select disease-resistant variety；Soil disinfection；Sterile soil culturing and transplanting seedlings；Strengthen cultivation management, note irrigation and drainage, anti-
Only long-time field hydrops after rain and after irrigating；The timely prevention and control of seeding stage, transplanting time and seedling stage；Medicament is prevented
Prosecutor method is: use 50% fluazinam (good fortune is handsome to be obtained) suspending agent to process soil before sowing；Also can emerge
Select the medicament medicinal liquids such as Bravo, cyazofamid, carbendazim, thiophanate methyl to water after phase, transplanting and execute (root
Portion's soil waters to execute needs description spraying 3-4 times of consumption), protect vegetable sprout term root system not by clubroot
Bacterium infect harm, pathogenic bacteria once invades root system enlargement, and prevention and control just do not have effect.But these technology are raw
Often being difficult to position on product, prevention and control not in time, and increase cost, are easily caused agricultural product and farmland
It is contaminated.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, give full play to bio-diversity and ecological disease-control
Feature, infect according to pathogen plasmodiophora and occurrence features, it is provided that a kind of new simple and effective prevention and control knee
Sick method.
To achieve these goals, a kind of method that the invention provides prevention and control clubroot, the method includes:
In the soil containing clubroot disease, plant Chinese cabbage, treat that Chinese cabbage grows to prosperous root out for a long time, then
The another kind of brassicaceous vegetable of plantation in this soil, wherein, described Chinese cabbage is Shandong spring white 83-1, gold zone
In vain, spring happiness 04-2 and spring like at least one in HUANGBAI(sic) morning.
Pass through technique scheme, it is possible to effectively for the soil prevention and control cross containing clubroot disease
Flower section clubroot, is greatly lowered sickness rate, to prevention and control Cruciferae clubroot and raising yield aspect meaning
Justice is great.
Other features and advantages of the present invention will be described in detail in detailed description of the invention part subsequently.
Detailed description of the invention
Hereinafter the detailed description of the invention of the present invention is described in detail.It should be appreciated that this place is retouched
The detailed description of the invention stated is merely to illustrate and explains the present invention, is not limited to the present invention.
In the present invention, term " prevention and control " refers to based on prevention so that the sickness rate fall of clubroot
To less than 20%.
End points and any value of scope disclosed in this article are not limited to this accurate scope or value, this
A little scopes or value should be understood to the value comprised close to these scopes or value.For numerical range, respectively
Between the endpoint value of individual scope, between the endpoint value of each scope and single point value, and individually point
Can obtain one or more new numerical range between value with combination with one another, these numerical rangies should be regarded
For the most specifically disclosing.
A kind of method that the invention provides prevention and control clubroot, the method includes: toward containing clubroot cause of disease
The soil of bacterium is planted Chinese cabbage, treats that Chinese cabbage grows to prosperous root out for a long time, then plantation is another in this soil
