Abstract

The invention discloses a summer management application method for fruit trees, relates to the field of fruit tree planting, and is mainly used for growth management of the fruit trees at high temperature in summer. In summer, the growth speed of most of the fruit trees slows down; shoots are topped; vegetative growth is converted into reproductive growth; the morphodifferentiation of flower buds begins, and is gradually completed; meanwhile, the climate is hot in summer, the fruit trees are susceptible to drought, flood, hail and gale, the plant diseases and insect pests reach a peak period, and are easy to be rampant; and the summer pruning, pinching, top dressing and the control of the plant diseases and insect pests in the period are crucial for achieving the high yield and the bumper harvest of fruits in this year and the next year; therefore, the invention particularly introduces the summer fruit tree management technology.

Description

The summer management application method of one planting fruit-trees

Technical field

The present invention relates to the planting fruit trees field, be primarily aimed at summer high temperature and carry out the growth management of fruit tree.

Background technology

Enter the hot summer days, fruit tree management has also just entered the critical period.The management in this period not only is related to a fruit size, and flower bud differentiation is had a significant impact.Summer climate sweltering heat simultaneously, fruit tree is subject to the harassment of drought and waterlogging, hail, strong wind, and the development of damage by disease and insect has also entered the peak, easily rampant the generation.Do the fruit tree integrated management in this period well, most important to the fruit high yield good harvest of capturing this year and the coming year.

Summary of the invention

One, the summer cuts: pinching, short flower improves fruit-setting rate.To the young sprout pinching in slow vegetative period, can promote sublateral shoot to sprout, reduce nutrient consumption, be beneficial to bud and form, be the balance tree vigo(u)r, can do sth. in advance and repeatedly pinching enriching shoot.Draw a spreading angle.Prosperous extending shoot is drawn branch, weighs down branch or smoothes out with the fingers branch, the major branch that spreading angle is little and grow that prosperous upright young sprout draws or with the hand level of smoothing out with the fingers into or sagging.Cutting back promotes to expand hat.When treelet ends of the branch at different levels reach 50～80 centimetres, carry out cutting back, and extract 1～2 leaf under the clip,, promote into the bow structure fruit, also be beneficial to the expansion tree crown to inspire the secondary branch.Turn round tip cultivation results branch.When young sprout base portion semi-lignified, turn round the tip, the prosperous length of inhibition is arranged and promote into colored remarkable result.But turning round the tip should not be advisable above 1/10 of back branch sum.Thin branch improves illumination.When canopy, can remove overstocked young sprout of part or unserviceable water sprout, note directly staying tiltedly, stay a little less than going strong, after staying before going.Cut stripping,, promote into colored with slow growth.Girdling can suppress the prosperous length of branch, and the accumulation that has additional nutrients promotes bud to form.The main position of girdling is the bough base portion, and band girdle can hinder the nutrition of tree body and carry downwards.

Two, topdress: late June fruit begin to expand, root growth is rapid, absorption function is active, is prone to and takes off fertile phenomenon, answers timely and appropriate discovery to topdress, and with supplemental tree body desired nutritional, shortly spends short fruit.Topdress with the composite fertilizer of nitrogen, phosphorus, potassium three elements to well.1～1.5 kilogram of 40～60 kilograms of people's animal manures, 0.3 kilogram in urea, 0.5 kilogram of superphosphate, 0.5 kilogram of potassium sulphate or Nitrogen, Phosphorus and Potassium is executed in the general strain in high yield orchard.Usually adopt radiating fertilization, and will try one's best and topdress or behind rain, rob and execute and draw the hoe soil moisture conservation in conjunction with irrigating.Take spray leaf fertilizer simultaneously, its effect is more remarkable.

Three, the extermination of disease and insect pest:

1. the control of disease.Rot: strike off scab, amputate the disease branch, scrape the sick scar in back and be coated with 10 times of liquid Miefulings, 10 times of liquid Miefulings of brush are to root out former bacterium on trunk, the major branch.Ring spot: June, early and middle ten days sprayed 600 times of liquid of 25% carbendazim or 500 times of liquid of 50% captan.Powdery mildew: spray 20 times of liquid of 50% sulphur deflocculant or 3000～4000 times of liquid of triadimefon.Anthracnose: spray bordeaux mixture, and every about 20 days, spray 600 times of liquid Tuzets for the second time.

2. the control of insect pest.Phytophthira: spray 1000 times of liquid of 1500 times of liquid of 50% Aphox or 50% malathion.The young worm dispersed phase of a red-spotted lizard class: spray the kerosene emulstion of oil content 0.5%～1% or the lime sulfur of Baume 0.3～0.5.Leaf rollers: spray bacillus thruingensis No. 6 or 95% chlorophos, 1500 times of liquid of 40% dichlorvos.

Technique effect

By carrying out cultivation management work such as diversion irrigation, pruning and the extermination of disease and insect pest, effectively controlled the damage by disease and insect incidence of disease of fruit tree in summer, the coming year, fruit tree grew fine, remarkable benefit.

Specific embodiment

We test mountain forest jujube tree, peach, apple tree etc., and by following work, effect is obvious:

1, after the summer has set in every about 10 days bactericide of spray add insecticide and add foliage fertilizer 3-4 time that contains humus.Bactericide and insecticide will be used alternatingly, and must guard against and use single medicament samsara to use.As refreshing 1 pouch of 1 bag of the rich foliage fertilizer in 6000 times+field of green 800 times+acetamiprid of newborn copper or 5000 times+green field of 600 times+Avermectin of Cao Shi first holder or 50% iprodione 1000 times+25% go out 2000 times of 1 bag of No. 3+green storm of young urea or 800 times+foliage fertilizer of 70% safe and sound life, 1 bag+40% Le Siben missible oil etc.

2, in time cut the vertical branch of cella, major branch back, water sprout, intersection, overlapping branch etc. are opened illumination, realize the light transmittance of fruit tree being reached about 40% ventilation and penetrating light, help photosynthesis and flower bud differentiation.

3, entering summer is the critical period that fruit expanding period and flower bud differentiation form, the nutrition that this period, fruit tree consumed is maximum, it is very necessary to replenish rich water to fruit tree, so impose the composite fertilizer of high-load potassium sulfate type or contain phosphorus potash fertilizer 2-3 time of high humic acid type every about 15 days.2 jin of fertilizer of hundred jin of fruits of topdressing amount adopt radiating fertilization, and topdress or rob behind rain and execute and draw the hoe soil moisture conservation in conjunction with irrigating, and take spray leaf fertilizer simultaneously.

Claims
