Abstract
The invention discloses a late frost antifreezing agent for walnuts. The late frost antifreezing agent for the walnuts is characterized by being prepared by compounding a salicylic acid aqueous solution, a jasmonic acid aqueous solution, a benzoic acid aqueous solution, acetum of insect chitosan, trace element mother liquor, alcohol, glycerinum and water. According to the late frost antifreezing agent for the walnuts, the sprouting time of flower and leaves is delayed, and the late development of sprouts is promoted, so that the effect of preventing a walnut tree from late frost is realized; the antifreezing agent has the advantages that the sprouting time of the flower and leaves can be obviously delayed by 10 to 15 days under the same temperature condition, so that the time the walnut tree is damaged by the late frost in early spring can be effectively avoided.
Description
technical field
The invention belongs to plant-growth regulator field, relate to a kind of frostproofer, particularly a kind of walnut late frost frostproofer.
Background technology
Walnut is China's mountain development economy and the mainstay industry of increasing farmers' income, one of main dry fruit export varieties of Ye Shi China.Along with the fast development of rural economy and improving constantly of people's living standard, the nutritive value of walnut and nourishing function are favored by consumers in general.Frost damage is the important factor of restriction China's walnut natural production and harvest, and it affects much larger than walnut disease and pest, in Yunnan, China's walnut main producing region and Shaanxi Province, all has walnut frost damage problem.Walnut suffer frost generally in the fall early frost or spring cold spell in later spring occur period, walnut frost damage is produced and is had very serious implications walnut, particularly the harm of the late frost in early spring is particularly serious, not only cause branch slightly dehydration drain death, flower, leaf, bud dry up and come off, and can cause the significantly underproduction of walnut, even total crop failure.The anti-control techniques of research walnut frost damage, the prevention of carrying out walnut frost damage is of great significance the Walnut tool of China.
Traditional plant frostproofer, all how much adopt plant hormone, as plant-growth regulator (ethylene inhibitor C6H12N2O3), Plant hormones regulators,gibberellins etc., the subject matter of its existence is: once that concentration is grasped is inaccurate, may cause that plant germination is strongly inhibited, serious situation even causes the underproduction and growth and development of plants disorder.
Summary of the invention
The object of this invention is to provide a kind of walnut late frost frostproofer, its change traditional plant frostproofer generally uses the not enough problem of plant hormone, by utilizing nutritive element and plant endogenous property semiochemicals to regulate walnut to grow, walnut is reached delay bud and the effect that leaf bud, bud later stage grow is sprouted, promoted to leaf bud, to avoid the frostbite of late frost to the sprout that sprouts, reach the effect of anti-late frost.Compared with using plant hormone with traditional plant frostproofer, this formula forms without the resistance of plant hormone, character gentleness, energy excited nucleus peach self and delays bud, leaf bud sprouting.
Technical scheme of the present invention is: a kind of walnut late frost frostproofer, is characterized in that: this walnut late frost frostproofer be by the acetum of aqueous solution of salicylic acid, the jasmonic aqueous solution, the phenylformic acid aqueous solution, insect shell glycan, micro-mother liquor, ethanol, G & W is composite forms.
The walnut late frost frostproofer of preparation 1L needs composite the forming of raw material of following mass volume ratio: the acetum of 0. 1-5.0% aqueous solution of salicylic acid, the 0. 1-5.0% jasmonic aqueous solution, the 0.1-3.0 % phenylformic acid aqueous solution, 0.1-1.0% insect shell glycan, 0.1-5.0% trace element mother liquor, 5-30% ethanol, 10-50% glycerine, surplus are water; Wherein, described micro-mother liquor is to be formed by weight 1:1:1 is mixed by copper sulfate solution, zinc sulfate solution and manganese sulfate solution.
The preparation method of described walnut late frost frostproofer is: successively the acetum of the aqueous solution of salicylic acid of formula ratio, the jasmonic aqueous solution, the phenylformic acid aqueous solution, insect shell glycan and micro-mother liquor are mixed, and then add successively ethanol, the G & W of formula ratio, fully mix bottling.
Described walnut late frost frostproofer sprays for 2 weeks before early spring, walnut bud was sprouted.
Before described walnut late frost frostproofer uncork, be soaked in 50-60 DEG C of hot water 5 minutes, take out firmly concussion and shaking up, guaranteeing do not have solid to separate out in bottle; When use, with 500 times of tap water dilutions.
Advantage of the present invention is: frostproofer of the present invention is to utilize the formula combination that the harmless plant endogenous property semiochemicals of plant, chitosan, trace element etc. is combined to form to induction walnut frost resistance, there is the walnut of delay bud, leaf bud sprouting effect, delay bud, leaf bud sprout time reach 10～15 days, the effect of avoiding late frost harm be can reach, thereby anti-late frost, antifreeze effect reached.Meanwhile, the trace element in formula and chitosan also can further excite other degeneration-resistant reaction of plant and promote the late growing stage of bud, leaf bud, and the growth of walnut body is not had a negative impact.Compare with traditional plant frostproofer, this prescription is containing any plant hormone class growth regulator, character gentleness, growth and development of plants do not caused to interference, belongs to trophicity regulating plant resistance and retarded germination effect.Wherein, chitosan has obvious physiological regulation function to plant ammonia assimilation key enzyme, can improve the ability of plant assimilation NH4+, is conducive to biosynthesizing and the accumulation of protein, improves nutritional quality and the proterties of plant; And can excite rapidly the defense response of plant, and open vegeto-animal system of defense, effectively improve the resistance of plant.
