Abstract
A kind of plant growth regulator that contains dihydrolagarane polyalcohol ester composition and preparation method thereof, its component is root bark of celastrus angulatus extract 3-10%, emulsifier 5-10%, solvent 92-80%, stir and obtain brown transparent missible oil, during preparation the root bark of celastrus angulatus powder is added in the extractor, add solvent lixiviate in the time of 50 ± 5 ℃ and discharge extract after 6 hours, it is formulated according to the above ratio more at last No. four extracts to be carried out drying.Use this plant growth regulator can promote plant growing, prevent and treat disease, do not have any contamination.
Description
The present invention relates to a kind of plant growth regulator that contains dihydrolagarane polyalcohol ester composition and preparation method thereof, belong to the technical field of plant growth regulator.
Monarch Wu Wen of northwest agricultural university is entitled as " research of pesticide plant Celastrus angulatus " literary composition and mentions that bioactivator mainly is distributed in the root skin interim publication of 1991 " agricultural chemicals " 30 volume the 6th, is suitable for the missible oil that is processed into pure pulvis and contains extract 20%.Can control the harm of following insect effectively through the field trial proof: cabbage caterpillar, rice plant skipper, turnip sawfly, aulacophora femoralis, oriental tobacco budworm, Chinese scholartree looper, corn weevil etc.Its KPT pulvis and BS missible oil have 4 kinds of biologically actives, i.e. food refusal, anesthesia, poisoning and bactericidal activity, but do not see the relevant report that utilizes the Celastrus angulatus extract to make plant growth regulator so far.
The purpose of this invention is to provide a kind of plant growth regulator that contains dihydrolagarane polyalcohol ester composition, its key component dihydrolagarane polyalcohol ester extracts from the wild plant root bark of celastrus angulatus.
Another object of the present invention provides a kind of preparation method who contains the plant growth substance of dihydrolagarane polyalcohol ester composition.
A kind of its component proportioning (by weight) of plant growth regulator that contains dihydrolagarane polyalcohol ester composition provided by the invention is as follows:
Root bark of celastrus angulatus extract (former medicine) 3-10%
Emulsifier 5-10%
Solvent 92-80%
The manufacture method of plant growth substance of the present invention comprises the steps:
1. extract
The root bark of celastrus angulatus powder is added in the extractor, the organic solvent (for example benzinum, ethyl acetate, chloroform etc.) that adds weight again and be 1.5 times in root bark of celastrus angulatus powder carries out lixiviate, extraction temperature is 50 ± 5 ℃, after 6 hours, from extractor feeding compressed air suitable for reading, discharge extract, in extractor, add solvent again, repeat above-mentioned operation 3 times.Merge the extract that obtains, place alembic.
2. distillation
Feed steam in the alembic interlayer and heat, heating and temperature control reclaims solvent in 80-90 ℃ of scope, stop distillation when condenser does not almost have distillate, and blowing is extract while hot.
3. dry
With extract dry under 50-60 ℃ of temperature in drying room (or using spray drying process), to remove contained a small amount of solvent, dry extract that obtains or Powdered thing promptly are the former medicines of this plant growth regulator.
4. preparation
With the former medicine of root bark of celastrus angulatus extract that above-mentioned three steps obtain, emulsifier, solvent mixes in following ratio (by weight):
Root bark of celastrus angulatus extract (former medicine) 3-10%
Emulsifier 5-10%
Solvent 92-80%
Obtain brown transparent missible oil after stirring, be plant growth regulator of the present invention.
Emulsifier is: the 1:1(of alkylphenol polyoxyethylene class nonionic surface active agent is by weight) mixture
Solvent is: the mixture of dimethylbenzene and ethanol.
For vegetables such as cauliflower, Chinese cabbage, radish, use this plant growth regulator, aspect the prevention and elimination of disease and pests of volume increase obvious effects is being arranged also.
Compared with prior art, the present invention's plant growth regulator of containing dihydrolagarane polyalcohol ester composition has the following advantages:
1. adopting the wild plant root bark of celastrus angulatus is that raw material directly extracts, and does not adopt synthetic, aboundresources, and technology is simple.
2. technical process waste discharge not, residue also can be used as fertilizer etc., though there is a small amount of solvent to volatilize in atmosphere in the extraction process process, does not exceed limit standard.Whole technology can not cause environmental pollution.
3. this plant growth regulator is effective, former medicine LD
50＞20000mg/Kg(mouse) to the person poultry harmless.Another advantage is can compare to natural enemies security, non-general synthetic plant growth regulator.
Embodiment 1:
With this plant growth regulator; be diluted with water to 1000 times or 2000 times of emulsions; to every mu of ground spray pesticide 50Kg; every 10 days spray medicines once; spray altogether 4 times; this plant growth regulator can make the growth of cucumber mattress phase vigorous; output is the average volume increase in contrast area 20-29.1%; and cucumber strip shapeliness; commodity melon rate height, thousand amount contrasts of kind melon melon seeds full seed are high by 10.7%, few downy mildew that takes place of whole growth phase; damage by disease and insect such as Leucoplakia, but other areas of identical product (for example Zheng is yellow No. 2) all need repeatedly prevention and elimination of disease and pests.
Embodiment 2:
The root bark of celastrus angulatus powder is added in the extractor, add the solvent that weight is 1.5 times of amounts of root bark of celastrus angulatus powder (chloroform or benzinum) again and after 6 hours,, discharge extract by extractor feeding compressed air suitable for reading in 50 ± 5 ℃ of following lixiviates of temperature, add solvent again, repeat this operation 3 times.No. four extracts are merged in the alembic of packing into, at 90 ℃ of following heating recovery solvents, when condenser does not almost have distillate, stop distillation with steam, blowing, what obtain is extract.Extract is dry under 60 ℃ in drying room, put the cold dry extract that obtains, i.e. the former medicine of this plant growth regulator.
(by weight) more in proportion, former medicine 3-10%, emulsifier 5-10%(alkylphenol polyoxyethylene non-ionic surface active agent), the mixture of solvent 92%-80%(dimethylbenzene and ethanol) mixes, stir, get brown transparent missible oil, be this plant growth regulator.
