The growth regulator is prepared by mixing paclobutrazol, nucleotide and imbalance sodium sulfite according to a certain ratio. According to the aim of application, the growth regulator is sprayed in different growth periods of the fruit trees, which can increase the content of chlorophyll, enhance the strength of photosynthesis, decrease the apical dominance and thicken the cell juice extractor. The growth regulator has the action of protecting leaves and fruits, keeping fresh and increasing flowers, sugar and weight. By increasing a leaf function, prolonging the leaf life, increasing the number of leaves and reducing the gap between the higher production and the lower production of the fruit trees, the production stabilization and the production increase are realized.
Description
Growth regulator for fruit tree belongs to and contains inorganic and plant growth regulator organic compound.
Utilize plant growth regulator and other approach improve fruit trees fruit rate and output, improving the fruit tree quality is the problem of progressively having researched and solved on the production of fruit trees.As handle with nucleotide citrus can improve citrus unshiu Marcovitch fruit rate and output, and improve fruit quality; The data report is also arranged, and paclobutrazol also has certain effect to increasing citrus production with the quality of improving fruit.Another ubiquity on but fruit is produced at present, the stable development influence that long-term again insoluble biennial fruiting problem is produced normal growth and the fruit of fruit tree is very big.The approach that solves the biennial bearing of fruits result in the general production practices has two.The one, fruit thinning, promptly the young fruit period in good year sprays growth regulator, makes a part of fruit abscission; Or adopt manual method that overstocked too much young fruit is extractd.The 2nd, the wheel rotation result, promptly good year young fruit period with the fruit people of weak tree, Mi Shu for coming off, make this part tree result in next year: or on same strain is set, the young fruit of part branch group is come off, allow another group bear fruit, result's branch is not organized the result in next year, in the hope of the stable yield balance.But said method all is to obtain little annual bearing with reducing big annual production, does not bring into play the yield potentiality of fruit tree maximum, is not satisfied measure.
The present invention is intended to the ramification problem that the appliable plant growth regulator solves biennial bearing of fruits, to guarantee stable every year fruits output.
The technical scheme that realizes task of the present invention is, growth regulator for fruit tree is to be mixed with certain proportion by paclobutrazol (C15H20N30Cl), Sodium Metabisulfite (NaS2O5) and three kinds of components of nucleotide to form, and three kinds of components contents are
Paclobutrazol 60-80%
Sodium Metabisulfite 20-30%
Nucleotide 2-5%
Be described in further detail the present invention below.
In recent years, brainstrust has had certain progress to the research of biennial bearing of fruits result's physiological mechanism, and having proved influences the part of biennial fruiting mechanism.During as the big annual bearing of apple, seed has synthesized too much class GA material, thereby the flower bud differentiation that has suppressed vegetative bud is the origin cause of formation of biennial fruiting; The citrus biennial fruiting also is to make next year flower quantity not sufficient form little annual bearing because the fruit of overload has synthesized too much class GA material.Also having research to point out to carry the fruit amount is to suppress flower bud differentiation, forms the immediate cause of sweet orange biennial fruiting.The Lao Ye that survives the winter has significant power function relationship with spending amount then, therefore wants citrus stable high yield year after year, must the suitable Lao Ye that survives the winter be arranged assurance every year.Therefore be to overcome the biennial bearing of fruits approach of phenomenon as a result from preventing to fall leaves, reduce the synthetic of class GA material and increasing that aspects such as Hua Liang set about.But solve the reported in literature of biennial fruiting problem in the not relevant as yet so far production practices.The growth regulator for fruit tree that the present invention proposes, be with paclobutrazol, lay particular stress on after sodium sulphate, three kinds of components of nucleotide is mixed in certain proportion, according to the growth potential of fruit tree, spray respectively at the different times of growth and development of fruit tree, can overcome biennial bearing of fruits phenomenon as a result.
The production method of nucleotide:
Geotrichum candidum generally contains nucleic acid about 8%, the waste liquid of available sugar refinery, brewery or Gourmet Powder Factory is cultivated geotrichum candidum, cultured geotrichum candidum liquid is collected with 100 mesh sieves, flushing obtains the geotrichum candidum thalline, add 0.4 centinormal 1 hydrochloric acid or phosphoric acid, make PH reach 1-2, heating is boiled, and notices that adjusting pH value does not at any time exceed PH2.Boil after thick, be adjusted to PH7 with 1%NaOH liquid, boil again or vacuum drying to thick.After adding an amount of carrier absorption, the 120-200 mesh sieve is crossed in vacuum drying, pulverizing, is the nucleotide pulvis of no hygroscopicity, and its nucleotide content is about 60%.
Sodium Metabisulfite and paclobutrazol are ready-made chemical products, its content be respectively 90% and 15%, three kind of component ratio in accordance with regulations be finished product after evenly mixing, soluble in water, be faintly acid, can use with foliage fertilizer, also can use with acid agrichemical.
The using method of growth regulator for fruit tree:
The every bag of finished product is 15g, and dilute with water during use adds certain water gaging furnishing pulpous state earlier, adds water to the 15-30 kilogram again, stirs, and leaf surface spraying concentration is generally 500-1000PPm.
The period that sprays of general fruit tree is as follows:
(1) each spray of good year flower bud differentiation early stage and later stage once can make to increase flower off year.
(2) the autumn growth leaf stretching period sprays once, can reduce fallen leaves and improve the fruit tree cold tolerance, and can make the weightening finish of this season fruit, increases sugar, precocity; Increase flower next year.
(3) in bud stage and physiological fallen fruit phase spray usefulness, but flower and fruit protecting improves setting ratio and the single fruit weight and the sugar content of fruit.
(4) megathermal period spray usefulness can reduce the high temperature shedding.
(5) anticorrosion resistant effect is arranged, low concentration can be done the fresh preservation agent.
The using method of growth regulator for fruit tree on citrus is as follows with effect:
(1) protect Ye Zenghua: in five leaf phases of autumn growth spray usefulness, every bag is converted 16 kilograms in water, has the leaf of guarantor to survive the winter and increases colored effect the coming year.Being suitable for regional or big annual bearer of fallen leaves in winter and the too much tree of result adopts.
(2) fruit retention presses down the tip, divides secondary to spray.In the spray in preceding 1-4 days of blooming, every bag is converted 25 kilograms in water, can substitute fully and manually smear the spring tip, reduces young fruit significantly and comes off for the first time; Sprout for summer shoot for the second time sprayed in preceding 1-2 days, and every bag is converted 20 kilograms in water, can partly replace manually smearing summer shoot, reduces shedding in June and high temperature dry season shedding in July, and fruit is had short long effect of gain.
(3) the fresh-keeping flower that increases: 1-3 days spray usefulness after the fruit picking, every bag is converted 20 kilograms in water, has to increase the flower effect.Soak fruit with same concentration, can reduce fruit rot, improve the storage rate.
Its result was as follows after citrus used growth regulator for fruit tree:
(1) improves photosynthetic function, accumulate leaf nutrient, reduce photorespiration; Spray usefulness can be protected the Lao Ye safe overwintering when autumn growth 5-7 leaves have launched, does not fall leaves or few fallen leaves (table one).To too much because of the result, tree that over-burden and the northern fringe easily fall leaves the area stable high yield most important.
(2) can make the cell juice enrichment, C/N ratio increases, and class GA material reduces.Increase flower (table 1) in the flower bud differentiation period spray off year with making.
(3) can suppress or slow down the plant shoot growth, weaken apical dominance.When the citrus spring tip develops into three leaves and launches fully or preceding 2-3 days spray usefulness of blooming, can suppress the spring tip and hail, reduce the contradiction of fruit tip contention nutrient and hormone, save and manually smear the tip, improve the young fruit rate.In summer shoot preceding 1-2 spray usefulness of sprouting, can postpone or suppress summer shoot and sprout, reduce the shedding in June, improve setting ratio (table 2).
(4) can promote that leaf nutrient enters fruit.Expand the peak period spray with making the fruit weightening finish at fruit; To the orchard of non-irrigated condition, fruit can be not too small yet, and fruit carbohydrate and sugar are increased.
(5) have sterilization and minimizing respiration, double as fruit antistaling agent (table 4).
