In addition, at least one herbicide of component C) is included.

Description

Specification is a kind of to have the plant growth regualting composition that prevents that the seed ear bud from sprouting

Technical field

The present invention relates to have the plant growth regualting composition that contains natural abscisic acid that suppresses the fringe rudiment, ICL belongs to A01N37/06.

Background technology

Natural abscisic acid, S-Abscisic acid (S-ABA), agricultural chemicals common name: S-abscisic acid.Molecular formula: C ₁₅H ₂₀O ₄, chemical name is: and 5-(1 '-hydroxyl-2 ', 6 ', 6 '-trimethyl-4 '-oxo-2 '-cyclohexene-1 '-yl)-3-methyl-2-is suitable-and 4-is anti--pentadienoic acid, chemical structural formula is as follows

The chemical constitution of S-ABA

Abscisic acid was extracted from the cotton young fruit by people such as Addicott 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, abscisic acid is that plant " degeneration-resistant inducible factor " reaches " the balanced growth factor ", it can start plant stress-resistance gene expression, the endogenous immune system of activated plant, inducing plant produces resistance to biological and abiotic stress (arid, low temperature, saline and alkaline, damage by disease and insect), improve drought resisting, cold-resistant, the disease-resistant and anti-salt alkali ability of plant, can be widely used in fields such as agriculture forest and husbandry, afforestation, ecological vegetation recovery.

The sulphur that accelerates the ripening claims dimethipin (Dimethipin) again, for example is disclosed among Liu Chengrong " Taiwan agriculture exploration " 1998 (4) 19-20: the using method of dimethipin plant growth regulator; And laugh at shape recklessly and edit " new English-Chinese agricultural chemicals dictionary " 1999,10 the 1st editions, described dimethipin in the Foreign Language Press and can make cotton, nursery stock, bamboo grows, vine disleave, flax, rape, paddy rice, sunflower seeds water content in the time of also can promoting fruit maturation and reduce results.

Cereal plants seed ear bud as the fringe rudiment of breeding of hybrid rice, when being meant breeding of hybrid rice, because high-temperature high humidity climate before the results brings out grain at head sprouting, causes de-vitalizing seed.Still do not have at present and effectively prevent method and control measure, annually already bring very big loss for the production of hybrid seeds.Cereal crop milk ripe stage or stage of yellow ripeness, though can be used for preventing gramineous plants seed ear bud, as rudiment of hybrid rice fringe and wheatear rudiment, the consumption of S-ABA is too big, the agriculture production cost height with S-ABA (70-200ppm) for list.

It is reported that in addition a spot of weed killer herbicide such as glyphosate, alachlor, butachlor etc. have certain inhibitory action to seed sprouting.

Summary of the invention

The object of the invention provides a kind of plant growth regualting composition that contains natural abscisic acid that prevents cereal crop seed ear bud that has, and it is characterized in that comprising in the said composition A) natural abscisic acid and B) sulphur accelerates the ripening.

Can also contain component C in the plant growth regualting composition of the present invention) at least a weed killer herbicide.

Surprisingly, S-ABA of the present invention and the composition that accelerates the ripening sulphur and add weed killer herbicide on this basis surpass the adduction of expection to the growth regulating-activity of crop, mainly are the field of activities that has improved every kind of composition on the one hand; Reduce the application concentration of natural abscisic acid and other plant growth regulator and the combination of this plant growth regulating on the other hand and also under individualized compound is lower than the situation of valid density, obtain good plant growth regulating level.Therefore this composite use can significantly reduce the consumption of S-ABA, saves cost, more effective fringe bud rate that prevents, and the output and the quality of raising cereal crop seed.
