Description
Technical field
The invention belongs to field of agricultural cultivation, be specifically related to a kind of method of preventing and treating pear tree fruit drop.
Background technology
Pear tree is rose family pear, perennial deciduous fruit tree, arbor.Have in the whole world and distribute widely.Fruit can be practical, has very high nutrition and medical value.Pear tree is in its systematic growth, and ubiquity the problem of fruit drop, and the reason of pear tree fruit drop is a lot, has the reason of kind, also has the reason of miscarriage.Mismanagement, trunk infusion is not enough or nutrient distribution is improper, nourishes and grows prosperous, and fights for fierceness with nutrient of yielding positive results, a large amount of fruit drop can be caused to produce, and over-burden or other reason to set body the previous year, and nutrient accumulation is few, have impact on branch, the educating of bud, spending of abortion is many, and fallen flowers are increased.Because fertilizing amount is not enough or partially execute some fertilizer, lack trace element fertilizer and cause soil nutrient to be lacked of proper care or de-fertilizer, cause pear tree to set fruit drop.If there is serious damage by disease and insect, directly consume a large amount of nutrients of pear tree, thus cause the nutrient of flowers and fruits not enough, also can cause fruit drop, badly influence the income of orchard worker.Further, therefore, a kind of method of preventing and treating pear tree fruit drop is badly in need of.
Summary of the invention
The invention is intended to provide a kind of method of preventing and treating pear tree fruit drop, to solve in prior art by poor management, soil fertilizer deficiency and the problem that damage by disease and insect causes pear tree fruit drop occurs.
Prevent and treat a method for pear tree fruit drop, comprise the following steps:
1) erection bracket around every strain pear tree, support comprises the dead lever that some are vertically inserted soil, is provided with connecting rod between dead lever, and the major branch of pear tree is dry to be all bundled on dead lever and connecting rod, dead lever is fixedly connected with many hoses, hose comprise water inlet and water side;
2) when the florescence, the potassium dihydrogen phosphate of spraying concentration 0.2%, every spray in 10 days 1 time, continuous spraying 3 times;
3) respectively spray the mixed solution of 1 hypoborous acid and pulverized limestone at bud stage, initial bloom stage, full-bloom stage, boric acid concentration is 0.3%, and the weight ratio of boric acid and pulverized limestone is 3:1.
Operation principle of the present invention and beneficial effect:
Erection bracket around every strain pear tree, support comprises the dead lever that some are vertically inserted soil, is provided with connecting rod between dead lever, and the major branch of pear tree is dry to be all bundled on dead lever and connecting rod, dead lever is tied with hose, hose comprise water inlet and water side.Due to when the florescence and connect fruit the phase play strong wind time, limb is acutely rocked, a large amount of flower and fruit can be caused to drop, by dead lever and connecting rod cooperatively interact fixing major branch do, effectively can reduce the shaking degree of pear tree limb, reduce the generation of fruit drop, and on dead lever, be tied with hose, hose comprise water inlet and water side, such design, to allow when spraying insecticide or apply fertilizer, only need be carried by hose, orchard worker may stand on support, hold the water side of hose, directly to spray, more traditional mode, decrease the use of special sprinkling machine, more convenient and quick, to spray insecticide or after foliage fertilizer, only need spray 2 water again, agricultural chemicals residual in hose or foliage fertilizer can be cleaned up, avoid the waste of agricultural chemicals or foliage fertilizer.
When the florescence, the potassium dihydrogen phosphate of spraying concentration 0.2%, every spray in 10 days 1 time, continuous spraying 3 times, when being due to the florescence, the a large amount of P elements of growth needs of flower and potassium element, if lack the few potassium of phosphorus, cold hardiness will be reduced, blossom few, bud is weak, impact is yielded positive results, cause fruit-setting rate low, therefore P elements and potassium element should be supplemented in time this period, potassium dihydrogen phosphate can meet the demand of two kinds of elements simultaneously, spray in 10 days once, continuous spraying 3 times, the whole florescence can be covered, but slowly carry out because pear tree absorbs nutrient, apply too many if disposable, pears also cannot all absorb, and the P elements had more and potassium element are run off in soil, cause waste.
The mixed solution of 1 hypoborous acid and pulverized limestone is respectively sprayed at bud stage, initial bloom stage, full-bloom stage, boric acid concentration is 0.3%, the weight ratio of boric acid and pulverized limestone is 3:1, boron can promote the elongation of pollen germination and pollen tube, be beneficial to completing of Pollination Fertilization, and corolla can be made normally to come off, thus improve percentage of fertile fruit.Pulverized limestone has the effect of sterilization, add mixing in spray acid to spray, can effective killing pathogenic bacteria, the weight ratio of boric acid and pulverized limestone is 3:1, pulverized limestone concentration under this proportioning is diluted to safe range, blade of can not burning, and due to lime be physical sterilization, there is no residue of pesticide, more safer than spraying agricultural chemicals.Active ingredient in pulverized limestone is calcium carbonate, can isolate the calcium ion that can be absorbed by plants, for pear tree provides calcium constituent under the effect of boric acid.Due to the element that calcium is plant growth necessity, it is the important component forming plant cell wall, indispensable to firm cell wall structure, calcium enters in absciss layer, formation hormone is abscisic acid (ABA) and ethene (C2H), and growth hormone (IAA) and gibberellin (GA) have antagonism, therefore when calcium deficiency with ABA and C2H, abscisic acid (ABA) and ethene (C2H) content reduce, the formation of Developing restraint element (IAA) and gibberellin (GA) thereupon.Growth hormone (IAA) and gibberellin (GA) content reduce, and can promote that carpopodium forms absciss layer, make the operatic circle be easy to drop, therefore pulverized limestone is pear tree supplementing calcium element, can prevent carpopodium from producing into absciss layer, reach the effect of fruit retention.
When spray and the mixed solution of pulverized limestone time, mixed solution can be prevented the water inlet of hose, by the conveying of hose, directly be sprayed onto on pear tree blade face and limb.Use this programme effectively can reduce the phenomenon of pear tree fruit drop, reduce the loss of orchard worker.
Further, described water side is connected with 360 degree of atomizers, make like this need not people go operate water side, get final product 360 degree of comprehensive sprinklings, atomizer can allow spray liquid let go evenly.
Further, upper end and the pear tree tip of described dead lever are positioned at sustained height, multiple 360 degree of atomizers interval between the pear tree tip to minimum leaf layer is arranged, hose water side can be allowed to be bonded to the height of the pear tree tip, then by the sprinkling of 360 degree of atomizers, the leaf of most top layer can be directed onto, is overlapping together owing to having between leaf, each leaf layer of pear tree can be allowed all to be sprayed to so the interval of multiple 360 degree of atomizers is arranged.
Further, described hose is provided with valve at ground place, and such people stands in the switch that ground just can freely control to spray, convenient and swift.
Further, the water inlet of described hose is all connected to water pump, such liquid that can make can from being located in toward eminence conveying, and allow liquid have certain flow rate in hose, when liquid sprays from 360 degree of atomizers of water side, sprinkling shape can be formed, make liquid be sprayed onto each leaf area of pear tree.
