Abstract
A plant growth regulator able to prevent and eliminate diseases and pests of plant contains proportionally light RE, tri-acontanol, amino acid, chitosan, cyclodextrin, potassium nitrophenolate, sodium naphthethylphenolate, hymexazol, metalaxyl and trace element fertilizer.
Description
Technical field
The present invention relates to the composite growth regulator of the anti-plant disease of a kind of energy.
Background technology
Plant growth substance is used very wide in agricultural production, it can be divided into plant hormone and plant growth regulator two big classes, and wherein obtaining universally recognized plant hormone kind at present has auxins, gibberellin class, cytokinin, abscisic acid and ethene five big classes.In addition, also have rape element, moonlight element and polyamines element etc. also to have the growth substance activity.Each plant growth regulator has certain activity on physiological action, its specificity is arranged again, also have certain condition and scope in the use, just can show its remarkable effect and special-effect, and in the existing plant growth regulator, major part all is the moment in growing process to play regulating action.The promotion of tillering as germination, root of hair, cell, perhaps to bloom, solid, promotion that fringe is real, the promotion of the nutrition fertility of increase of useful composition or the like does not then have preventive and therapeutic effect for the damage by disease and insect of plant.
Triacontanol is a kind of a kind of plant hormone that extracts from honeybee is cured, and crop is had the activity of adjusting, and various crop is had significant effect of increasing production, it is few that it has a consumption, advantages such as cost is low, harmless to people, animal, and is easy to use, that effect is obvious, and is free from environmental pollution.
Rare earth is the important resource of China, and many scientific workers carry out a large amount of and fruitful research work to many-sides such as rare earth application and relevant environment safeties, has obtained abundant achievement.Confirmed that rare earth element and compound thereof have spread effect to plant growing; A spot of use can promote growth and development of plant, promotes nutrient absorbing, conversion and utilization, promotes its photosynthesis, thereby improves crop yield.The researcher has found its preventive and therapeutic effect to plant disease when APPLICATION OF RARE-EARTH ELEMENTS and compound thereof, and then has confirmed the bacteriostasis of rare earth element to bacterium and disease fungus again.Having proposed with rare earth element as application for a patent for invention CN1582664 is organic compound disinfectant of main sterilization.
Shitosan be a kind of by chitin by the deacetylated semi-synthetic derivative of producing.It is widely adopted in the agriculturally useful compositions of various various objectives.At present, existing many open source literatures have reported that water soluble chitosan has purposes widely on agricultural and other industry, for example have disease and insect resistance, degeneration-resistant, be used as fresh-keeping or the like the purposes of fertilizer, plant.As the application of anti-plant disease, JP2000-212013A has described a kind of inhibitor with antifungic action that comprises aqueous solution shitosan, salicylic acid, magnesium acetate and saleratus; The application of as fertilizer sources composition, JP11-199417A has described a kind of plant growth stimulator that comprises the chitosan solution and the rotten acid extractants thing aqueous solution or the like; Though mention the performance such as disease-resistant, degeneration-resistant, fertilizer efficiency of shitosan or water soluble chitosan in the prior art, these application have suitable limitation, for example only limit to some specific germ and specific floristics or the like.
The eighties in 20th century, people began the research of cyclodextrin and its derivative, and finding all has in various degree production-increasing function with its crops of handling, but its mechanism and intension to increasing crop yield also is not very clear till now, but this does not influence its application.
There is the various plants growth regulator in the prior art, but major part all is the particular growth physiology course that is used to regulate specified plant, lack the plant growth regulator that to prevent that anti-plant pest again can coordinate plant growth, lack the plant growth regulator that can be widely used in various crop.
At present in existing technology, use many as the volume increase agent of triacontanol and rare earth separately, both are mixed the fewer of use, mainly be that triacontanol is water insoluble, make it be restricted with the application that mixes of other reagent; In addition, people still do not understand for the production-increasing function mechanism of cyclodextrin, therefore, itself and other reagent mix effect afterwards also often is difficult to expect, this makes cyclodextrin and derivative thereof actually rare when using as the volume increase agent, does not also find and the three mixed to use at present as plant growth regulator.
Rare earth and shitosan can both the diseases prevention sterilizations, but they are combined might not reach as bactericide not only increases production but also the purpose of diseases prevention sterilization, because the rare earth of high concentration is to suppress plant growing, and rare earth uses under higher concentration as bactericide separately, therefore, their mixing blindly may both be had influence on their bactericidal effect, do not have the effect of volume increase again.
The technical issues that need to address of the present invention just are to provide a kind of efficient multicomponent energy disease-resistant plant growth regulator, the present invention integrates the various effects of triacontanol, shitosan, rare earth element and compound thereof, cyclodextrin and derivative thereof, and adds the needed trace element of plant growing, amino acid, and various bactericide and prepare efficient multicomponent plant growth regulator based on this again; A kind of product that can improve disease-resistant crops such as cereal crops in the growth, vegetables, fruit tree, resistance is provided, and finally reaches and make increasing crop yield and increase excellent purpose.In addition, raw material of the present invention is that stable, water miscible, easy operating and cost are low.Therefore, a further object of the present invention provides a kind of method nontoxic, non-harmful green agricultural product of producing.
Summary of the invention
The invention provides a kind of new plant growth regulator, it contains triacontanol, shitosan, cyclodextrin, rare earth element and/or its compound, and as the other plant growth regulator (as potassium para-nitrophenate, naphthalene diethylstilbestrol sodium) of selectable components, trace element fertilizer (as zinc sulphate, copper sulphate, iron sulfate, manganese sulphate etc.), bactericide, amino acid and/or its compound commonly used.Described hereinafter umber all refers to weight portion.
Further, plant growth regulator provided by the invention preferably contains 1-5 part triacontanol, 20-40 part shitosan, 10-15 part rare earth and/or its compound.
Above-mentioned plant growth regulator can also contain 1-5 part potassium para-nitrophenate, and/or 1-5 part naphthalene diethylstilbestrol sodium.
Described cyclodextrin can be that any combination or the independent use of α, β, gamma-cyclodextrin is wherein a kind of, can be 5-15 part.
Described bactericide can be, for example dislikes arbitrary combination of mould spirit, metalaxyl, tpn or uses the common fungicide that is fit to wherein a kind of and that those of ordinary skills select according to goal of the invention separately, can be 5-20 part.
Described trace element fertilizer can be trace element fertilizer commonly used, and is an amount of as boric acid, borax, calcium chloride, calcium sulphate, zinc sulphate, copper sulphate, iron sulfate, manganese sulphate, ammonium molybdate etc., as 1-20 part.
