Abstract
The invention discloses a method for preventing and controlling taxus chinensis anthracnose. The method comprises a step (1) of preparation of chemical mixed liquid and a step (2) of spraying time and times. According to the method, the key point of taxus chinensis anthracnose is achieved. Methyl jasmonate can induce the generation of resistance substances in taxus chinensis bodies and improve plant disease resistance to anthracnose, the growth of taxus chinensis can be promoted, and disease conditions are relieved. Mildothane belongs to efficient and no-residue bactericides, the use of the mildothane does not affect medicinal value of taxus chinensis, the number of disease specks is reduced, the disease index is lowered, and thus the growth amount of taxus chinensis is improved. The method has good economic and social benefit in actual application.
Description
Technical field
The present invention relates to rare plant cultivation field in imminent danger, the cultivation method field of the plant-Chinese yew be specifically related to integrate medicinal, viewing and admiring, particularly relate to a kind of prevention and controls of Chinese yew anthracnose.
Background technology
Chinese yew is taxaceae Taxus evergreen plant, is first-grade state protection rare tree species, be integrate medicinal, view and admire, afforest, the rare tree of extraordinary high quality timber.The whole world about has 11 kinds, and China is distributed with 4 kind of 1 mutation, be respectively taxusyunnanensis (
taxusyunnanensis), Chinese Chinese yew (
taxuschinensis), Xizang Taxus chinensis (
taxuswallichianaZucc), taxus chinensis in northeast (
taxuscuspidata) and southern enqlish yew
(Taxus.Chinensisvar.mairei), be distributed in China's most area.Owing to having extracted taxol from this platymiscium, and prove that this compound has very strong activity for cancer, thus cause extensive attention.The states such as the U.S., Canada, Britain, Sweden official approval formulation for paclitaxel are used for the clinical treatment of first-line drug or the invalid Metastatic carcinoma in the ovary of chemotherapy subsequently.Carry out clinical testing widely to formulation for paclitaxel at present, result shows it has unique curative effect to breast cancer, non-small cell lung cancer etc., and thus it has a extensive future.But the exclusive source of this material is extraction and isolation from natural frond at present.In the bark of bearing tree, content is the highest, also only have 0.01-0.02%, and this plant distributions is scattered, poor growth, be difficult to the demand meeting growing clinical testing and treatment aspects, will cause to the aspect such as species, ecology the loss being difficult to make up to a large amount of fellings of this kind of wild resource.
Because natural taxus resource is extremely limited, and be the rare tree species of state guarantee, so artificial planting Chinese yew becomes the main source extracting taxol.In recent years, along with the expansion of Chinese yew artificial planting area, its disease increases the weight of year by year, and anthracnose generally occurs in nursery stock and young growth, causes very large economic loss, has become a large obstacle of development Chinese yew artificial planting.
The colletotrichum gloeosporioides Penz of Chinese yew colletotrichum in anthrax-bacilus classification [
colletotrichumgloeosporioides(Penz.) Sacc.].The Suitable ranges of this mycelial growth is 20-30 DEG C; Producing spore optimum temperature range is 25-30 DEG C; The optimum range of conidia germination is 20-30 DEG C.This pathogen under 12h alternation of light and darkness condition mycelial growth and conidia germination all best, loose light-struck sporulation quantity is maximum; The conidia germination of this pathogen is very high to the requirement of humidity, does not sprout below 60%, and only when humidity reaches more than 95%, conidium just has higher germination rate.
Chinese yew Anthracnose Pathogen bacterium survives the winter in Chinese yew diseased tissues with mycelium.Pathogen is mainly propagated by wind and rain by conidium.From late April to mid-May, along with the progressively rise of temperature, it is movable that this disease also gradually starts in pin main body, occurs new scab successively; After early June, field occurring degree also increases the weight of gradually; Along with temperature raises, rainfall increases, and 7-9 month disease development speed reaches the fastest; 10-11 month, the state of an illness was basicly stable along with the decline of temperature, and disease stops development.
Therefore solve Chinese yew anthracnose and prevent and treat this difficult problem, reliable technical support can be provided for the expansion of Chinese yew artificial planting area, to resources of medicinal plant regeneration in short supply in imminent danger and sustainable utilization significant.
Summary of the invention
The object of the invention is to provide a kind of a kind of prevention and controls of Chinese yew anthracnose, realizes the standardization of Chinese yew, large-scale planting as early as possible.In order to realize this purpose, at the understanding characteristic of anthracnose, the regularity of occurrence and development of disease, exploring on the basis of its mechanism of causing a disease, proposing a kind of a kind of prevention and controls of Chinese yew anthracnose.The method utilizes in a plant growth regulators induction Chinese yew body and produces resisting substance, strengthen the disease resistance of self, add a kind of efficient, low toxicity bactericide, kill anthracnose spore and mycelia, solve the difficult problem that conventional control Chinese yew anthracnose technology exists.
An a kind of prevention and controls for Chinese yew anthracnose, specifically comprises following steps:
(1). the configuration of medicine mixed liquor; (2). the time of sprinkling and number of times.
The method of the configuration of described step (1) medicine mixed liquor is: a. takes 1g methyl jasmonate, first dissolves with a small amount of 95% ethanol, then is settled to 1L with water; B. 70% thiophanate methyl is configured to 450-550 times of liquid; C. being diluted by Tween-20 is 0.5%; D. the liquid methyl jasmonate by volume then will configured: the ratio mixing and stirring of thiophanate methyl: Tween-20=6:3:1.
The time that described step (2) is sprayed and number of times are specially: by the liquid configured annual 4-5 month, anthracnose was not also fallen ill time be evenly sprayed on Chinese yew blade face, within general 5-7 days, spray once, connect spray 3 times; If Chinese yew blade has occurred the scab of anthracnose, should spray once every 3 days, connect spray 3-5 time.
The concentration of described methyl jasmonate is 3.5-5.5mmol/L.
The optimum concentration of described methyl jasmonate is 4.5mmol/L; The optimal dose of 70% thiophanate methyl is 500 times of liquid.
Owing to have employed above technical scheme, the present invention has following beneficial effect: this key link solving the control of Chinese yew anthracnose, methyl jasmonate can be induced in Chinese yew body and be produced resisting substance, improve plant to the disease resistance of anthracnose, the growth of Chinese yew can also be promoted, alleviate the state of an illness.Thiophanate methyl belongs to efficiently, noresidue bactericide, and its use does not affect the medical value of Chinese yew, greatly reduces scab number, and disease index reduces, thus improves the amount of growth of Chinese yew, and practical application achieves good economic and social benefit.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention being clearly and completely described.
