Abstract

The invention relates to a method of controlling hot pepper epidemic disease and corn big spot by cultivating hot pepper and corn in heterogeneity, belonging to plant protection field. The technique project of this invention is: keeping the mode of current hot pepper sprout cultivation and hot pepper and corn field cultivation, the plant distance, line space and density between the hot pepper and corn is the same with normal cultivating method. Opening furrow with width being 2-5m and depth 15-30m in the same field, planting hot pepper with 5-10 lines on the furrow surface, planting corn with 1-2 lines on the two sides of the furrow, the line space between the hot pepper and corn is 10-30cm, the corn seeding time can be same with the hot pepper transplanting time or seeding corn 1-15 days earlier than the hot pepper transplanting time, the hot pepper and corn can be planted relatively or in displacement. The invention can control the hot pepper epidemic disease and corn big spot with a good effect, can reduce the using amount of chemical pesticide greatly, increase product yield per unit area, and possesses outstanding economical, social and ecological benefit and wide application prospect.

Description

The method of corn and the capsicum diversity growing control capsicum epidemic disease and the corn northern leaf blight
Technical field
The present invention relates to a kind of method of controlling the capsicum epidemic disease and the corn northern leaf blight, platymiscium protection field.
Background technology
Capsicum is one of main vegetable crop of the extensive plantation of China, and along with development, the reform of rural area cropping system and the industry restructuring of chilli products processing industry, the pepper cultivation area constantly enlarges, and the annual production of bright green pepper of China and dried green pepper at present occupies first place in the world.Capsicum epidemic disease is a kind of destructive disease on China and whole world capsicum produce, and the field is morbidity in a single day, and capsicum is large stretch of dead in a few days, and area reaches 30%~50%, and the grave illness district is up to 80%~100%.Because being capsicums, the capsicum variety that still non-resistant is stable at present, kind is good, pesticide control produce the important means of preventing and treating eqpidemic disease.Capsicum epidemic disease has the characteristics of soil-borne disease and aeroborne disease, brings great difficulty to disease control work, relies on simple chemical control for a long time and impels germ to develop immunity to drugs also to be present capsicum to produce to go up the eqpidemic disease disease serious key factor takes place.
Corn is a third place in the world generalized grain crop, the second largest cereal crops of China.The corn northern leaf blight is the important disease on the Maize Production, and plant introduced disease rear blade forms the withered spot necrosis of large tracts of land, has a strong impact on photosynthesis and plant strain growth and causes the corn underproduction.It is similar to capsicum epidemic disease that traditional corn northern leaf blight is prevented and treated method, mainly is to use disease-resistant variety and chemical pesticide, and tangible pesticide resistance all appears in above-mentioned two kinds of diseases at present, makes cost increase, control efficiency reduction and the contaminated environment and the agricultural product of pesticide control.Therefore, press for the deficiency that a kind of new method of preventing and treating substituted or remedied existing method.
Summary of the invention
Main purpose of the present invention is the deficiency that overcomes existing method, provide a kind of and can prevent and treat the method that capsicum epidemic disease can be controlled the corn northern leaf blight again so that capsicum and Maize Production can high yield, high-quality, shape up efficiently.
The technical scheme of this method is to keep present capsicum seedling, capsicum and corn field production mode, between capsicum and the capsicum, corn is identical with the conventional cultivation method with spacing in the rows, line-spacing and density between the corn, and ploughing the first furrow as a guideline with conventional identical in the plot, adds kind of a corn in the piece of same field, moisture in the soil face width degree 2~5m, wide 30~the 60cm of dead furrow, dark 15~30cm plant 5~10 row capsicums, maize planting on the both sides, moisture in the soil limit on the moisture in the soil face, every side is planted 1~2 row, and the line-spacing between corn and the capsicum is 10~30cm.Corn seeding phase and capsicum field-transplanting phase can be identical or corn transplant sowing in preceding 1~15 day in capsicum, the spacing in the rows of corn and capsicum can be 40~50cm for 30~40cm, line-spacing, corn and capsicum can misplace to sky and plant.The kind of corn and capsicum is not limit.
This method is to have carried out extensive and deep investigation in pathogen, generation development and propagation harm to the capsicum epidemic disease and the corn northern leaf blight, and on the basis that the multiple method of preventing and treating is compared, invented and utilized the species diversity principle capsicum and corn to be carried out the method for the intercropping control capsicum epidemic disease and the corn northern leaf blight.Capsicum and corn plants height differ greatly, form three-dimensional plant group after both intercropping and be unfavorable for the environment that disease takes place, corn is not the host of capsicum epidemic disease, and the corn northern leaf blight can not infect capsicum, thereby thereby can block mutually each other that the route of transmission of disease reaches good control effect.Simultaneously because shading of corn reduced " sunscald " of capsicum in summer; Corn self is because the reduction of planting density and improved by optical condition has strengthened the resistivity to leaf blight, and single plant yield also is improved.The application of this method has strengthened the stability of field ecosystem, has improved the anti-disaster ability of crops, has reduced the usage amount of agricultural chemicals significantly, has remarkable economical, society, ecological benefits.To recovering, preserve and rationally use the variety of crops resource, explore sustainable agriculture and be of great practical significance simultaneously.

The above results shows, though corn or capsicum variety difference, the degree that its corresponding disease takes place is different, but corn and capsicum diversity growing are a kind of effective ways of controlling the capsicum epidemic disease and the corn northern leaf blight, wherein the sick effect of the control of capsicum epidemic disease is prevented and treated increase with the reduction of capsicum line number, the sick effect of the control of the corn northern leaf blight is prevented and treated increase with the increase of capsicum line number.The combination of corn large group and capsicum microcommunity is favourable to the control of capsicum epidemic disease, but because the capsicum economic worth is higher than corn, for embodying the benefit of capsicum corn diversity growing, should notice that the corn pepper proportioning is suitable.In a word, this technology can alleviate the harm of the capsicum epidemic disease and the corn northern leaf blight, reduce the use of chemical pesticide significantly, and remarkable economical, society and ecological benefits are arranged.
