Abstract
The invention discloses a method using lavender to control flue-cured tobacco plant diseases and insect pests. The method includes the steps of changing a monoculture method of flue-cured tobaccos, firstly transplanting the lavender 30 days before transplanting of the flue-cured tobaccos, and planting one row of lavender and one row of flue-cured tobaccos. Through adoption of growth habit difference between the lavender and the flue-cured tobaccos, the lavender has specific aromatic odor, and volatile constituents of the lavender have a bactericidal effect and can eliminate the plant diseases and insect pests. In addition, the lavender is less in the plant diseases and insect pests, so the lavender can enable the incidence of the plant diseases and insect pests of the flue-cured tobaccos to be reduced. Through intercropping between the lavender and the flue-cured tobaccos, the method can be used for controlling occurrence of various plant diseases and insect pests of the flue-cured tobaccos, reducing usage amount of pesticide, and achieving the purposes of maintaining ecological balance and reducing insect control cost.
Description
Technical field
The invention belongs to flue-cured tobacco techniques of pest control fields, be specifically related to a kind of method of utilizing lavender to control the flue-cured tobacco damage by disease and insect.
Background technology
Flue-cured tobacco is one of important economic crops of China, and in the production process of flue-cured tobacco, the tobacco disease insect pest is the Universal Problems that affects its growth.Use more method to be chemical pesticide control in production practices, yet along with the popularization of organic tobacco leaf planting, require not use agricultural chemicals in during production process of flue-cured tobacco, therefore, how in the situation that not applying pesticides reduce damage by disease and insect to the impact of flue-cured tobacco, be the problem that we need to solve.
Lavender is that the Labiatae lavender belongs to, and has been just quite general vanilla at Roman period, because its effect is maximum, is called as " after vanilla ".Just be widely used in medical treatment, stem and Ye Douke are used as medicine from ancient times, and the effect of stomach invigorating, sweating, pain relieving is arranged, and are the good medicine for the treatment of cold, stomachache, eczema.The lavender dried flower has anthelmintic action, and Lavender can be used as bactericide.At present in industry extensive uses such as daily use chemicals, medicine, food.
Utilizing the crop interplanting mode to control the Various Diseases insect pest, reducing the fertilizer and pesticide amount of application, improve the compound output of crop is one of important application technology during traditional farming is produced.But flue-cured tobacco and lavender intercropping be there is not yet report in the prior art with the method for controlling the flue-cured tobacco damage by disease and insect.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of method of utilizing lavender to control the flue-cured tobacco damage by disease and insect is provided.Change the monoculture method of flue-cured tobacco, the damage by disease and insect of controlling the tobacco growing phase by flue-cured tobacco and lavender intercropping culture occurs.
Purpose of the present invention is achieved by the following technical programs.
A kind of method of utilizing lavender to control the flue-cured tobacco damage by disease and insect comprises the following steps:
(1) carry out according to a conventional method respectively growing seedlings of flue-cured tobacco, lavender;
(2) the every ridge of lavender is planted delegation, the wide 0.5m of ridge, spacing in the rows 0.3m; Carry out flue-cured tobacco and transplant after lavender is transplanted 30 days, adopt " 1+1 " cropping pattern, namely plant tobacco planting delegation of delegation lavender; The every ridge plantation of flue-cured tobacco delegation, the wide 1.2m of ridge, spacing in the rows 0.5m;
(3) carry out daily management and fertilising, not spraying pesticide according to conventional method.
Utilize the habit of growth difference of lavender and flue-cured tobacco, lavender has special aromatic odor, and its volatile ingredient has bactericidal action, can drive damage by disease and insect, and himself damage by disease and insect is less, and the damage by disease and insect incidence of disease of flue-cured tobacco is reduced.
The present invention to control the generation of the various damage by disease and insect of flue-cured tobacco, reduces the usage amount of agricultural chemicals by lavender and flue-cured tobacco intercropping, reaches and keeps ecological balance, reduces the purpose of controlling the worm cost.
Description of drawings
Fig. 1 is the schematic diagram of flue-cured tobacco of the present invention and lavender intercropping.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is further described, but drawings and Examples are not limitation of the invention.
Embodiment 1
Flue-cured tobacco intercropping test
Experimental field: the Shilin county impression cigarette village, Yunnan Province
Test is divided into two groups: flue-cured tobacco nonoculture district; Flue-cured tobacco and lavender intercropping district.Two groups experimental field soil is suitable with topographic features, approximately 1 mu of area.
(1) flue-cured tobacco nonoculture district
Carry out the cigarette transplantation of seedlings mid-May, every ridge is planted delegation's flue-cured tobacco, the wide 1.2m of ridge, and spacing in the rows 0.5m does not apply any agricultural chemicals, way to manage fertilising routinely.
(2) flue-cured tobacco and lavender intercropping district
The lavender transplanting time is mid-April, transplants the cigarette seedling after 30 days.According to the plantation of " 1+1 " pattern, and plant the delegation lavender, then plant delegation's flue-cured tobacco.The lavender ridge is wide is 0.5m, spacing in the rows 0.3m; The flue-cured tobacco ridge is wide is 1.2m, and spacing in the rows 0.5m(is referring to Fig. 1).Do not apply any agricultural chemicals, way to manage fertilising routinely.
Implementation result: adopt generaI investigation and focal investigation combination in the tobacco growth phase, the flue-cured tobacco damage by disease and insect to be investigated.Tobacco Diseases a situation arises main investigation disease species, various disease rank, diseased plant number calculate the incidence of disease, average disease index, control efficiency; Insect pest a situation arises main investigation insect pest kind, Pests Damage cigarette strain number, insect pest quantity are calculated insect density and harm cigarette strain rate; The damage by disease and insect grade scale is with reference to the tobacco business relevant criterion.
Flue-cured tobacco Pests situation sees Table 1.Result shows, the damage by disease and insect in flue-cured tobacco nonoculture district is more; In flue-cured tobacco and lavender intercropping district, lavender is substantially without damage by disease and insect, and the various damage by disease and insect of flue-cured tobacco obviously reduce.As can be seen from Table 1, disease index and the incidence of disease of lavender and flue-cured tobacco intercropping district flue-cured tobacco only have 2.14 and 5.0%, and disease index and the incidence of disease of contrast reach 11.32 and 17.0%; Utilize and do between lavender and flue-cured tobacco the control efficiency of Tobacco Diseases is reached 81.10%; The worm strain rate of lavender and flue-cured tobacco intercropping district flue-cured tobacco only has 2.0%, and the worm strain rate of contrast is 12.0%.
Under the different cropping patterns of table 1, a situation arises for Tobacco Diseases
Can find out that the present invention rationally utilizes the method for lavender and flue-cured tobacco intercropping control flue-cured tobacco damage by disease and insect, the generation that can effectively control or alleviate the flue-cured tobacco damage by disease and insect is a kind of method of good agricultural planting prevention and elimination of disease and pests.
Claims (1)
1. method of utilizing lavender to control the flue-cured tobacco damage by disease and insect comprises the following steps:
