Description
Technical field
The present invention relates to blooming of fruit trees freezing proof technique field, be specifically related to a kind of freezing protection for fruit tree agent for improving pollination used inflorescence and preparation method thereof.
Background technology
Cold sensitive plant is above zero just showing the symptom of being injured under the cryogenic conditions, even dead.The position originally of injury from low temperature is a biomembrane, and under the cryogenic conditions, biomembrane is mobile to be reduced, and protein composition can not be exercised normal function, and the film of striding of solute transports, and energy transforms, and the enzymatic metabolism is suppressed, thereby causes injury.The photosynthesis of plant and the matter transportation that are damaged to plants caused by sudden drop in temperature are suppressed, and breathe and reduce, and protein synthesis weakens, and decompose and strengthen, and electrolyte exosmoses.Blooming of fruit trees generation freeze injury phenomenon is quite general, after blooming of fruit trees suffers freeze injury, and the atrophy of the lighter's pistil, the pollen vigor descends, and percentage of fertile fruit reduces, and the flower fertilization of can not normally pollinating causes a large amount of fruit drops; Weight person's flower is dried-up, dead.Fruit tree is influenced by frost at the florescence, the gently then underproduction, heavy then the total crop failure, bring enormous economic loss to the orchard worker.At present, the commercially available anti-freezing flower retention agent that is used for fruit tree, the plant absorbing availability is low, antifreezing effect difference and instability.
Summary of the invention
The purpose of this invention is to provide a kind of freezing protection for fruit tree agent for improving pollination used inflorescence, low to overcome existing freezing protection for fruit tree agent for improving pollination used inflorescence plant absorbing availability, antifreezing effect difference and unsettled shortcoming.
Another object of the present invention provides the preparation method of above-mentioned freezing protection for fruit tree agent for improving pollination used inflorescence.
The technical scheme that the present invention adopts is; A kind of freezing protection for fruit tree agent for improving pollination used inflorescence; By mass percentage, form by following component: 0.5%～10% zinc sulphate, 1%～16% potassium nitrate, 1%～15% nitrate of lime, 1%～8% boric acid, 5%～10% latex, 10%～35% antifreezing agent, 45%～65% water, 1%～10% surfactant; Above each component mass percent summation is 100%.
Wherein, The freezing protection for fruit tree agent for improving pollination used inflorescence; By mass percentage, form by following component: 1%～10% zinc sulphate, 3%～10% potassium nitrate, 3%～15% nitrate of lime, 1%～8% boric acid, 6%～10% latex, 6%～32% antifreezing agent, 45%～50% water, 1%～8% surfactant; Above each component mass percent summation is 100%.
Antifreezing agent is that concentration is that 95% ethanol, concentration are that 98% ethylene glycol or concentration are a kind of in 98% glycerine, or to select concentration for use be that 95% ethanol, concentration are that 98% ethylene glycol and concentration are that 98% glycerine is the mixture of 1: 1: 1 mixed by mass ratio for three kinds.
Surfactant is OP-10, and OP-10 is the condensation product of alkyl phenol and oxirane.
Another technical scheme that the present invention adopts does, the preparation method of freezing protection for fruit tree agent for improving pollination used inflorescence carries out according to the following steps:
Step 1,
By mass percentage, 0.5%～10% zinc sulphate, 1%～16% potassium nitrate, 1%～15% nitrate of lime, 1%～8% boric acid, 5%～10% latex, 10%～35% antifreezing agent, 45%～65% water, 1%～10% surfactant; Above each component mass percent summation is 100%;
Or by mass percentage, take by weighing 1%～10% zinc sulphate, 3%～10% potassium nitrate, 3%～15% nitrate of lime, 1%～8% boric acid, 6%～10% latex, 6%～32% antifreezing agent, 45%～50% water, 1%～8% surfactant; Above each component mass percent summation is 100%;
Step 2,
In agitated reactor, add entry earlier, begin to stir, in water, add while stirring behind zinc sulphate, potassium nitrate, nitrate of lime and the boric acid, in whipping process, continue to add latex and antifreezing agent again, to evenly mixing to dissolving fully; After in whipping process, adding surfactant at last, stir and stop after 10～30 minutes, promptly make anti-freezing flower retention agent of the present invention.
Antifreezing agent is that concentration is that 95% ethanol, concentration are that 98% ethylene glycol or concentration are a kind of in 98% glycerine, or to select concentration for use be that 95% ethanol, concentration are that 98% ethylene glycol and concentration are that 98% glycerine is the mixture of 1: 1: 1 mixed by mass ratio for three kinds.
Surfactant is OP-10, and OP-10 is the condensation product of alkyl phenol and oxirane.
The invention has the beneficial effects as follows that preparation is simple, cost of material is cheap, and plant absorbing is fast, the anti-freezing flower retention effect is remarkable, percentage of fertile fruit is high, safety and environmental protection, has improved the quality and yield of fruit greatly.
