Disease Investigation And Synthesis Preventing And Controlling Of Pretected-Foeld Vegetables In Luohe City

According to the unique geographical environment of Luohe city,if you want to better solve the mass basket problem you must spare no effort on develop the cultivation of protective area vegetables,the pretected-field vegetables cultivation is a more commonly vegetables cultivation type.However,the high temperature,high humidity,low wind speed and other ecological factors in the large plastic house create favourable conditions to the occurrence of various diseases.These diseases not only affect the output and quality of large plastic house vegetables,but also bring the vegetables production a grave threat.This article focuses on the vegetable cultivar and disease investigation of large plastic house vegetables production base in Luohe city suburb during 2005 December～2008 May.It analyzed the procreant characteristics of the mainly large plastic house vegetables diseases,and correspondingly made a environmentally harmless free integrated prevention and control scheme to large plastic house vegetables disease.1.the investigation showed that 15 kinds of vegetables in this area are being cultivated, some of which are more commonly cops,such as cucumber,tomatoes and pepper.2.in disease investigation,more than 20 types of commonly diseases are found in the ground,downy mildew,gray mold,early blight and powdery mildew are most serious.There are 15 kinds of cucurbit vegetable diseases,22 kinds of solanceous fruits diseases,5 kinds of legume vegetable diseases,9 other kinds of vegetable diseases in these vegetable diseases, they are the major types of the large plastic house vegetable diseases in this area.3.on the basis of the investigation of disease variety and disease endangerment,I analysed the procreant characteristics of disease and discussed the way of environmentally harmless free integrated prevention and control scheme on large plastic house vegetable disease,made persistently management measures. 4.warm awning vegetables main plant disease synthesizes the preventing and controlling technology the research to guard against the effect experiment through the tomato grey mould medicament,the tomato leaf mold medicament guards against the effect experiment,the cucumber frosty mildew medicament guards against the effect experiment,the cucumber root ties the wireworm medicament to guard against the effect experiment,the greenhouse heroin powder louse medicament medicament guards against the effect experiment and so on a series of experiments.Screens to prevents and controls the tomato grey mould to have well guards against the effect the medicament to have 40%Shi Jia happy,50%throws oneself Hydantoin, 50%spoiled mildew advantage,40%pyrimidine mildew saddle;Screens to prevents and controls the tomato leaf mold to have well guards against the effect the medicament to have 47%to add auspicious agricultural,60%armor frost spirit;Screens to prevents and controls the cucumber frosty mildew to have well guards against the effect the medicament to have 72.2%Pu to overcome AS800 time of fluid,64%kills poisonous vanadium WP600 time of fluid,72%gram dew WP800 time of fluid,47%adds auspicious agricultural WP800 time offiuid,70%lives WP800 time of fluid peacefully and undisturbed;Screens to prevents and controls the tomato leaf mold to have well guards against the effect the medicament to have 10%good fortune many,5%good year winter,1.8%Avey fungus element;Screens to prevents and controls the greenhouse heroin powder pediculosis to have well guards against the effect to have 25%sai insect qin,2.5%Gao Shenbi the insect lin,1.8%Avey fungus element.5.the greenhouse big awning vegetables plant disease non-environmental damage synthesizes preventing and controlling,has the characteristic and the tendency in view of the Luohe city area warm awning vegetables disease-carrying insect,must implement"the prevention primarily,synthesis preventing and controlling"plant protection policy.Also is must embark from the vegetable field ecosystem overall idea,extinguishes sickness by the insect proofing,pulls down the germ and the harmful insect cardinal number,creates one to be suitable for the vegetables growth growth not to favor environmental condition each agriculture,the ecology measure which the harmful insect occurs is the foundation,causes the vegetables growth to be vigorous and healthy before,is having massively the disease-carrying insect control damages;Already had the popular disease-carrying insect,had in line with safe, effective,economical,the simple principle,coordinated the use agriculture,biological, chemistry and the physical necessary preventing and controlling technology organically,had plant disease quantity and damages the degree control in the economical permission level, achieved high quality,the high production,synergized the goal.
