Description
Technical field：
The invention belongs to control of crop disease technical field, is related to a kind of biological pesticide of preventing and treating rice blast and its answers
Use method.
Background technology：
In worldwide, rice disease mainly has 3 types：Rice blast, bacterial leaf-blight and banded sclerotial blight, rice blast are made
For a kind of one of three major disease of worldwide Oryza sativa L., it is that, by the microbial fungal disease of rice blast, the disease throughout the year all can be right
Oryza sativa L. works the mischief, and its harm has Seedling rice blast, leaf pestilence, pulvinus pestilence, section rice blast, panicle blast, branch stalk throughout each position of Oryza sativa L.
Pestilence and grain pestilence etc., general morbidity can cause Oryza sativa L. underproduction 10%-30%, and when serious, No kernels or seeds are gathered, as in a year of scarcity.Therefore, the preventing and treating of rice blast
All it is the hot issue of scientists study all the time.
At present, the prophylactico-therapeutic measuress of rice blast are mainly chemical pesticide control and anti-rice blast breed breeding, but because changing
Learn to farm the harm of medicine and the Drug resistance of pathogen and the unification of anti-pestilence kind, rice blast biological strain multiformity and complexity
Property so that the use of chemical pesticide and Rice Resistance pestilence kind receives certain limitation in production application.However, biological agriculture
Medicine can improve the yield of Oryza sativa L. under conditions of not welding to greatest extent, with poisoning it is lower than chemical pesticide, be difficult
Develop immunity to drugs, raw materials for production extensively, trusted using safety, the advantages of environment compatibility is good, selectivity is strong, so biological pesticide
Research becomes the needs of the effectively focus of preventing and treating rice blast and sustainable development.Biological pesticide is divided into microbial source according to its source
Pesticide and botanical pesticide, and botanical pesticide can provide some new compounds or lead compound for chemical industry, institute
Increasingly to obtain the concern of chemist.Research shows, Neem seed, Schima superba Leaf, radish seed, peel of Fructus Sapindi Mukouossi, oil tea
Leaf, Folium cinnamomi camphorae and Fructus Cumini Cymini seed have inhibitory action to the spore germination of rice blast fungus or mycelial growth, to Pyricularia oryzae
Biocontrol effect is good.At present, by Neem seed, Schima superba Leaf, radish seed, peel of Fructus Sapindi Mukouossi, Camellia Leaves, Folium cinnamomi camphorae and diligent
Right seed carries out rational proportioning as raw material, and to prepare a kind of biological pesticide of preventing and treating rice blast, there is not been reported.
The management technique of rich water is very important, science apply phosphorus, potash fertilizer it is appropriate with the use of Rice Resistance can be improved
The ability of rice blast, has research also to show that the Rice Resistance characteristic of disease for applying siliceous fertilizer is remarkably reinforced, even if Oryza sativa L. infects rice blast still may be used
So that scab siliceousization, control scab development, can also make flourishing, anti-fall rice root, drought resisting, disease-resistant, pest-resistant power strong, while
Setting percentage height, the big panicle many grains per panicle of Oryza sativa L., obvious effect of increasing production can be made.
The content of the invention
In order to overcome limitation of the use of chemical pesticide and Rice Resistance pestilence kind in production application, the present invention to provide
A kind of prevention and controls of rice blast, including preparation and its application process of biological pesticide, and by Rational Application phosphorus,
Potassium, siliceous fertilizer are improving the ability of rice anti-rice blast.
To solve above-mentioned technical problem, the technical solution used in the present invention is as follows：
The invention provides a kind of prevention and controls of rice blast, including preparation and its application process of biological pesticide,
And Rational Application phosphorus, potassium, siliceous fertilizer, the preparation method of the biological pesticide is as follows：
Neem seed, Schima superba Leaf, radish seed, peel of Fructus Sapindi Mukouossi, Camellia Leaves, Folium cinnamomi camphorae and Fructus Cumini Cymini kind are plucked respectively
Son, cleans, dries, and is placed in 70 DEG C of baking oven and dries to constant weight, and then weighs Neem seed 20-30 weight portions, Schima superba Leaf 10-20
Weight portion, radish seed 5-10 weight portions, peel of Fructus Sapindi Mukouossi 5-10 weight portions, Camellia Leaves 7-10 weight portions, Folium cinnamomi camphorae 5-10 weight
Part, Fructus Cumini Cymini seed 8-10 weight portions, crush after mixing, cross 40 mesh sieves, add 70% alcohol steep 3 times of 200 weight portions, often
Secondary extraction 10 hours, merges lixiviating solution, and it is 1g/mL to be concentrated into mass concentration with Rotary Evaporators, moves loaded on 10mL tool plug scales
In test tube, sealing of jumping a queue is cold in 4 DEG C of refrigerators to deposit standby.
The application process of the biological pesticide of above-mentioned preventing and treating rice blast is as follows：
(1) soaked seed with biological pesticide
The biological pesticide 100g for taking above-mentioned preventing and treating rice blast is watered 50kg, rice 30kg of fetching water, and soak time is
50 hours, clean accelerating germination after medicinal liquid.
Preferably, the seed will be from disease-free Tian Liuxuan.
(2) using biological pesticide in rice field
In Oryza sativa L. tillering period, boot stage, full heading time, rice blast once, is such as found every 5 days investigation rice terraces, i.e.,
Prevent and treat during rice field should be administered to；Before dispenser, 30 times of water are added to dilute the biological pesticide of above-mentioned preventing and treating rice blast, per mu every time
Spray the biological pesticide 10kg after being watered dilution.
Preferably, by adding the foliage fertilizers such as phosphorus, potassium, siliceous fertilizer in the biological pesticide after the middle dilution of step (2), with life
Thing pesticide is synchronously sprayed, it is possible to provide nutrition necessary to Seedling strain growth, promotes its quick restoration ecosystem.
Further, described phosphate fertilizer is calcium phosphate, adds 300-500 gram of calcium phosphate in every 10kg biological pesticides.
Further, described potash fertilizer is potassium chloride or potassium sulfate, adds potassium chloride or potassium sulfate in every 10kg biological pesticides
300-500 gram.
Further, described siliceous fertilizer is nano silicon, adds nano silicon 300- in every 10kg biological pesticides
500 grams.
Beneficial effects of the present invention are as follows：
(1) biological pesticide of the preventing and treating rice blast that the present invention is provided has that poisoning is low, is not likely to produce Drug resistance, production
The advantages of raw material is extensive, safe, environment compatibility is good, selectivity is strong.
(2) above-mentioned biological pesticide is soaked seed by the present invention, and sprays when Oryza sativa L. tillering period, boot stage, full heading time are fallen ill
Impose in rice field, effectively reduce the sickness rate of rice blast, improve the survival rate and yield of Oryza sativa L..
(3) in Oryza sativa L. tillering period, boot stage, full heading time, nitrogen, phosphorus, potassium, siliceous fertilizer are added in the biological pesticide after dilution,
Synchronously spray with biological pesticide, the ability of rice anti-rice blast can not only be improved, moreover it is possible to reach the effect of volume increase.
