Plant growth regulator

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 [0001] The invention relates to a compound growth regulator capable of resisting plant diseases. Background technique [0002] Plant growth substances are widely used in agricultural production. They can be divided into two categories: plant hormones and plant growth regulators. Among them, the types of plant hormones that are generally recognized at present include auxins, gibberellins, cytokinins, Abscisic acid and ethylene five categories. In addition, brassinolide, moonshin and polyamines also have growth substance activity. Each plant growth regulator has a certain activity in physiological action, but also has its specificity, and there are certain conditions and ranges in use, so that it can show its significant action and special effect, and the existing plant growth regulator Among the agents, most of them can only play a regulatory role in a specific stage of the plant growth process. For example, the promotion of germination, rooting, and cell t...

Problems solved by technology

As an application against plant diseases, JP2000-212013A describes an inhibitor with an antifungal effect comprising aqueous chitosan, salicylic acid, magnesium acetate and potassium bicarbonate; as a fertilizer composition, JP11-199417A describes A kind of plant growth stimulator etc. that comprises chitosan solution and humic acid extract aqueous solution; These applications have considerable limitations, such as limited to certain specific bacteria and specific plant species, etc.

[0006] In the 1980s, people began to study cyclodextrin and its derivatives, and found that the crops treated with it had different degrees of yield-increasing effect, but the mechanism and connotation of the crop yield-increasing effects are still not very clear, but this is not the case. affect its application

[0007] There are many kinds of plant growth regulators in the prior art, but most of them are used to regulate the specific growth physiological process of specific plants. There is a lack of plant growth regulators that can prevent and resist plant diseases and insect pests and can also regulate plant growth. Plant Growth Regulators for Various Crops

[0008] At present, in the existing technology, triacontanol and rare earth are used alone as production increasing agents, and the combination of the two is relatively rare, mainly because triacontanol is insoluble in water, so that its mixed application with other reagents is limited. In addition, the mechanism of cyclodextrin’s production-increasing effect is still unclear, so the effect of mixing it with other reagents is often unpredictable, which makes cyclodextrin and its derivatives not suitable for use as production-increasing agents. More common, but the mixed use of the three as plant growth regulators has not yet been found

[0009] Both rare earth and chitosan can prevent and kill bacteria, but combining them together as a fungicide does not necessarily achieve the purpose of increasing production and preventing and killing bacteria, because high concentrations of rare earth inhibit plant growth, and rare earth alone acts as a fungicide Agents are used at higher concentrations, therefore, mixing them blindly may not only affect their bactericidal effect, but also fail to achieve the effect of increasing production
