Abstract
The plant growth regulator composition with dwarfing, ripeness promoting and resisting functions contains, other than conventional inert processing assistant, the following active components: natural abscisic acid, Pix and promoting-type plant growth regulator in the weight ratio of 1 to 0.01-100 to 0.001-10.
Description
Invention field
The present invention relates to have dwarfing, the plant growth regualting composition that contains natural abscisic acid of accelerating and degeneration-resistant effect, ICL belongs to A01N37/06.
Background technology
Natural abscisic acid, the general S-abscisic acid by name of agricultural chemicals (S-ABA), i.e. (+)-suitable, instead-and natural abscisic acid, chemical name: 5-(1 '-hydroxyl-2 ', 6 ', 6 '-trimethyl-4 '-oxo-2 '-cyclohexene-1 '-yl)-3-methyl-2-is suitable-and 4-is anti--pentadienoic acid, structural formula is as follows:
The chemical constitution of S-ABA
Natural abscisic acid (S-ABA) is listed as plant five big parahormones with growth hormone, ethene, gibberellin and the basic element of cell division.Natural abscisic acid was extracted from the cotton young fruit by people such as Addicot first in 1963.Three during the last ten years, the various countries scientist has carried out research extensively and profoundly to its physiologically active of plant effect, studies show that, natural abscisic acid is plant " a degeneration-resistant inducible factor ", play the important physical active function in each period of plant growing, particularly, has important effect inducing plant to improve aspects such as drought resisting, cold-resistant, anti-salt alkali ability and enhancing plant autoimmunity resistance against diseases.
S-ABA (1.0-100ppm) has cold-resistant, drought resistance function to crop, but dwarfing effect is not obvious.Help strong plain (Pix) but (10.0-300ppm) dwarfed plant promote setting, but can not cause prematurity, precocity fruiting.6-benzyl aminopurine (6-BA) (1.0-50ppm) and methyl (NAA) (1.0-50.0ppm) must handle plant for example the floral organ of cotton could promote setting, foliar spray is not obvious.
The present inventor is according to the physiologically active of plant effect of natural abscisic acid, with and with the repercussion study of other plant growth regulator etc., find surprisingly, when adopting inhibition type conditioning agent for example S-ABA or Pix when for example ethrel, methyl or 6-BA make up with the promoted type conditioning agent, then both can downgrade crop such as cotton, cucumber, promote setting, can reach prematurity, precocity fruiting again, early gather, and fruit quality has clear improvement, if run into cold, arid weather at fruiting period, then can bring into play drought resisting, cold-resistant effect, so finished the present invention.
Summary of the invention
The purpose of this invention is to provide a kind of plant growth regualting composition with dwarfing, accelerating and degeneration-resistant effect, said composition contains A) natural abscisic acid, B) help strong element and C) and at least aly be selected from following promoted type plant growth regulator: ethrel, 6-benzyl aminopurine, methyl, brassin lactones, gibberellin, acetylsalicylic acid, jasmonic or methyl jasmonate.
Surprising fully is, natural abscisic acid of the present invention and the multiple combination that is selected from the plant growth regulator of described plant growth regulator surpass the adduction of expection to the growth regulating-activity of crop, and improve especially the field of activity of every kind of composition aspect two: on the one hand, the plant growth regulator of natural abscisic acid and other from concentration reduce and keep good activity simultaneously, on the other hand, this new plant growth regulator combination also obtains good plant growth regulating level at individualized compound under the situation that no longer includes agriculture effect under the low concentration.
Promoted type plant growth regulator ethrel, 6-benzyl aminopurine, methyl, brassin lactones, gibberellin, acetylsalicylic acid, jasmonic or methyl jasmonate described in the present invention all are known, and be described in for example " external pesticide species handbook (new edition bound volume), the Ministry of Chemical Industry's agricultural chemicals central information facility; " newly organized agricultural chemicals handbook, The Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC, agriculture publishing house, 1989; " newly organized agricultural chemicals handbook (sequel), The Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC, agriculture publishing house, 1998.
Plant growth regualting composition of the present invention can be used for for example careless mould, the grape of cotton, cucumber, fruit, lichee etc.
Single have cold-resistant, drought resistance function with S-ABA (1.0-100ppm) to crop, but dwarfing effect is not obvious.Help strong plain (methyl piperidine, Pix) (10.0-300ppm) but dwarfed plant promote setting, but can not cause prematurity, precocity fruiting.And promoted type conditioning agent such as 6-benzyl aminopurine (6-BA) (1.0-50ppm) and methyl (NAA) (1.0-50.0ppm) must handle plant for example the floral organ of cotton could promote setting, foliar spray is not obvious.Adopt inhibition type conditioning agent of the present invention for example S-ABA or Pix and promoted type conditioning agent for example when ethrel, methyl or 6-BA combination, then both can downgrade crop such as cotton, cucumber, promote setting, can reach prematurity, precocity fruiting again, early gather, and fruit quality has clear improvement, if run into cold, arid weather, then can bring into play drought resisting, cold-resistant effect at fruiting period.Plant growth regualting composition of the present invention has been broken through the only synergistic effect on using of conventional compositions, two kinds of conditioning agents of inhibition type and promoted type make up for each other's deficiencies and learn from each other, make some conditioning agent shine the application youth, can under adverse environmental factor, increase output, can improve the quality of fruit again in various degree.
Generally speaking, when the present composition used, the ABA working concentration was 1.0-1000ppm, is preferably 1.0-500ppm, more preferably 1.0-50.0ppm; Helping strong plain working concentration is 1.0-500ppm, is preferably 10.0-300ppm, more preferably 50.0-250ppm; Promoted type conditioning agent working concentration is 0.01-500ppm, is preferably 0.01-100ppm, more preferably 1.0-50ppm.
Generally speaking, in plant growth regulator of the present invention, natural abscisic acid: help strong plain: promoted type growth regulator blending ratio (weight ratio) is between 1: 0.01-100: 0.001-10, and preferably between 1: 0.1-100: between the 0.01-10.
Application dosage can change in quite wide scope and depend on uses type (foliage-spray, smear, irritate root, injection etc.); The kind of cultivated plant, the vegetative period of plant, weather conditions etc.; With the other factors of being used the control of type and time.Usually, can be according to composition of the present invention with the application dosage of 0.01 to 2.50 kilogram of active component/hectare.Generally speaking, the application dosage of plant growth regualting composition is not crucial when using, and the natural abscisic acid concentration during crucial being to use should remain between the 1.0-1000ppm.
When using, adopts plant growth regualting composition of the present invention conventional dosage form.They use conventional mode, use the adjuvant that adopts usually in the preparation processing technology, but but are processed into for example missible oil, direct sprayable or dilute solution diluting emulsion, wetting powder, soluble powder, pulvis, granule or microcapsule formulations.
Preparation is adopted preparation in a known manner, for example, by with plant growth regulator and described processing aids, is typically solvent or solid carrier uniform homogeneous blend and/or grinding.Also can additionally use surface active cpd (surfactant) to prepare preparation.
The case description of solvent and solid carrier is in second piece of " formulations of pesticide process technology " second edition (Chemical Industry Press, 1998) of Liu Bulin chief editor.
Depend on the plant growth regulator that is intended to process, suitable surface active cpd is nonionic, cation, anion and/or amphoteric surfactant and the surfactant mixture with well emulsify, dispersion and wettability.
