Abstract
The invention discloses a method for controlling citrus fruit-drop in high temperature. The method comprises the steps that: an organic fertilizer is applied in time after fruit picking, and an appropriate amount of calcium superphosphate is doped in. Farm pig and cow manure are main components of the fertilizer. In approximately 1 week after flowers are faded, urea and potassium dihydrogen phosphate are sprayed on leaf surfaces. When spring shoots come out, controlling is carried out in time; green manure is alternately applied in the orchard, or tree plate covering is carried out, such that orchard water content is maintained. With the method provided by the invention, citrus fruit high-temperature resistance can be effectively improved, and physiological fruit-drop caused by high temperature can be substantially reduced.
Description
Technical field
The invention belongs to the fruit tree planting technique field, particularly a kind ofly prevent and treat the method that citrus high temperature causes shedding.
Background technology
The shedding that citrus causes due to high temperature is a kind of physiological fallen fruit.Physiological fallen fruit be fruit tree in growth and development process, a large amount of sheddings that cause due to the effect of on-mechanical external force and damage by disease and insect.High temperature causes that the main cause of the serious shedding of citrus is: physiological fallen fruit early stage be in young fruit cell division vigorous period, play pendulum on physiology this moment, easily forms absciss layer, under hot conditions, more promoted the formation of absciss layer especially.In addition, take out at the spring tip phase of sending out and high temperature occurs, promote that spring tip vegetative shoot occurs in a large number, consume more organic nutrient, thereby the contradiction that the spring tip and young fruit are fought for nutrient is more outstanding, causes serious shedding.
Summary of the invention
The objective of the invention is to cause for the high temperature that occurs in present citrus culture management the problem of a large amount of sheddings, a kind of method of preventing and treating the shedding of citrus high temperature is provided.
The technical solution used in the present invention main points are: timely applying organic manure after fruit picking, and thank and spray foliage fertilizer after spending, rationally control the spring tip, plant green manure between the orchard or the tree dish covers, soil moisture is not enough in time irrigates.
The method of operating of control citrus high temperature shedding is:
1, applying organic manure.After fruit picking, in time apply the fertilizer that fully becomes thoroughly decomposed, and mix the appropriate superphosphate of people.Pig, cow dung barnyard manure 20-40 kilogram, superphosphate 0.5-1 kilogram are executed in strain.This time fertilising increases stored nutrient very favourable for rapid recovery leaf function.Topdressing should be take the fruit tree Chemical Mixed Fertilizer as main, and in line with the principle of " on a small quantity repeatedly ", the degree of depth of topdressing should be shallow, general 10-15 centimetre comparatively suitable, should execute at the root system areal concentration, enlarge the contact-making surface with root system as far as possible, make root system early absorb, early take effect.Should water flood after fertilising 1 time.Should in time draw hoe after watering, keep loosing soil.
2, rationally control the branch growth, relax tip fruit contradiction.To in time erase for the vigorous spring tip of sending out of taking out.
3, plant green manure or the covering of tree dish between in the orchard, keep ground moistening, play simultaneously cooling effect.
4, foliage spray is named again in top dressing.Spend about a week thanking, strengthen foliage spray, in time spray 0.3% urea+0.3% potassium dihydrogen phosphate, spray in every 7-10 days 1 time connects and sprays 2-3 time, can spray in conjunction with spraying medicine.Before being preferably at 10 o'clock in the morning, after at 4 o'clock in afternoon or the cloudy day carry out, avoid spray at fine day noon fertile, in case high temperature causes fertilizer damage.
5, budding before and after, in time irrigate when soil moisture is not enough, and stay as far as possible and hold interior thorax branch, meet abnormal high temperature and will in time pour water, if sprinkling irrigation, spraying prevent the shedding successful.
Adopt said method, can prevent effectively that high temperature from causing the physiological fallen fruit of citrus.
Embodiment
The invention will be further described below by embodiment.
Embodiment:
At the beginning of 12 months, apply the fertilizer that fully becomes thoroughly decomposed.30 kilograms of pig, cow dung barnyard manure are executed in strain, 0.5 kilogram of superphosphate.Should in time draw hoe after watering, keep loosing soil.In spring, in time erase to the spring tip.Thank spend after a week, foliage-spray 0.3% urea+0.3% potassium dihydrogen phosphate, spray in every 7-10 days 1 time connects and to spray 3 times, plants soya bean, the maintenance ground moistening between in the orchard in.Through observation, the orchard fruit drop rate is than the original 70-85% that reduces.
Claims (1)
1. method of preventing and treating the shedding of citrus high temperature is characterized in that: timely applying organic manure after fruit picking, and mix the appropriate superphosphate of people, pig, cow dung barnyard manure 20-40 kilogram, superphosphate 0.5-1 kilogram are executed in strain.Thank and spend about a rear week, foliage-spray 0.3% urea+0.3% potassium dihydrogen phosphate, spray in every 7-10 days 1 time connects and sprays 2-3 time; Rationally control the spring tip; Plant green manure or the covering of tree dish between the orchard.
