Abstract
The invention relates to a method of controlling peanut brown spot and corn big spot by cultivating peanut and corn in heterogeneity, belonging to plant protection field. The technique project of this invention is: on the base of keeping the cultivating mode of peanut and corn, planting the two crops in displacement, the plant distance, line space and density between peanut and peanut, corn and corn is the same with normal cultivating method, planting peanut with different line ratio for interval cultivating, planting corn with 2-4 lines, peanut 2-10 lines, the line space between peanut and corn is 20-40cm. The invention can control the peanut brown spot 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
Technical field
The present invention relates to a kind of method of controlling the cercospora brown spot of peanut and the corn northern leaf blight, platymiscium protection field.
Background technology
Peanut is extensively a kind of economic crops of plantation of the whole world, and China is the second in the world major peanut big producing country.The cercospora brown spot of peanut is general property in a peanut producing region and Chang Fa venereal disease evil, often causes the fertility middle and later periods to fall leaves in a large number, and production brings heavy losses to peanut, the general underproduction about 20%, but fall ill the heavier underproduction more than 50% (Melouk and Shokes 1995).Height resists or the peanut varieties of immune brown spot owing to lack, and pesticide control is the important means of preventing and treating brown spot in the peanut production, but also still there is the peanut yield loss about 10% in chemical control.
Corn is that the third place in the world is big, 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 the cercospora brown spot of peanut 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 the cercospora brown spot of peanut can be controlled the corn northern leaf blight again so that peanut and Maize Production can high yield, high-quality, shape up efficiently.
The technical scheme of this method is to keep whole ground of ploughing the first furrow as a guideline of present peanut and corn and planting type, between peanut and the peanut, spacing in the rows between corn and the corn, line-spacing and density is cultivation method routinely, in the piece of same field, carry out the corn, peanut strip cropping by the different rows ratio, corn planting 2～4 row, peanut cultivation 2～10 row, the line-spacing between peanut and the corn is 20～40cm.
Wherein: the sowing time of corn and peanut can be identical, and corn and peanut can be to sky dislocation plantations.
This method is to have carried out extensive and deep investigation in pathogen, generation development and propagation harm to the cercospora brown spot of peanut 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 that peanut and corn are carried out the intercropping control cercospora brown spot of peanut and take into account the method for corn northern leaf blight control.Peanut 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 the cercospora brown spot of peanut, the corn northern leaf blight can not infect peanut, thereby thereby can block mutually each other that the route of transmission of disease reaches good control effect.Because peanut plant is short, increased the ventilation and penetrating light of corn, help corn and make full use of the space and bring into play individual advantage and can strengthen resistivity leaf blight, fringe is big, grain is many and aim of high yield thereby reach.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.
