Hole punching positions are determined and select areas with dense absorption root distribution under tree crowns, the mutual distance among holes is 130 to 200cm, the hole punching number is 4 to 8, and the hole punching depth is 30 to 150cm; the direction of the holes can be perpendicular, or the holes are punched in the oblique direction with 45 DEG towards the dense absorption root areas from 50 to 100cm apart from a dry basis, and corresponding filling material is placed according to site soil physical and chemical properties after the holes are formed. The present invention has the advantages that the soil permeability under the hard covering is increased, the permeability is favorable for reasonable and normal distribution of the roots, and the regression of the roots is effectively prevented; the oxygen content in the soil is increased and the ventilation performance is good, so trees can not be dead from suffocation because of oxygen deficiency; the water content of the soil is enhanced, the normal growth of the roots of the trees is protected, so the trees can be well developed, and the morbidity is reduced.
Description
Technical field
The invention belongs to the method for urban afforestation.
Background technology
Particularly northern city, the most of city of China is after entering middle nineteen nineties, along with the quickening of urban infrastructure speed, the stiff dough area of mating formation increases at a high speed, even under the thought guidance of " improve hygienic conditions, improve city image ", the not open-air slogan of loess has been proposed.For making things convenient for the pedestrian, the quality of mating formation of the road surface all " is improved " in the speed with annual hundreds of thousands square metre even millions of square metres in each city.Common brick by the past, the ordinary cement square brick develops into pavior brick, the square brick of the high rigidity of today, colored hilllock plate has been spread in some place, and has increased again under the road surface or thickeied tabia and concrete bed course, causes the soil beyond the tree well isolated with " generation " fully.Greatly change solid phase, gas phase and the liquid phase three-phase system that constitutes soil thus.And then, originally between the soil physical property of forming by inorganic matter, organic matter, soil moisture and soil gas, the chemical property of soil connect each other, connect each other, the entity of mutual restriction suffered conclusive destruction.
In recent years, we utilized the method that combines with detailed survey of investigation, to each diseased region in the location by street road and park, greenery patches, cement, pitch or square brick covering are arranged, be designated hereinafter simply as hard covering, exposed ground and ground cover plant cover, and are called for short soft covering, carry out different Classification Counts.
Result and analysis
1, soil porosity
Have or not hard covering directly to influence the gas permeability of soil, soil porosity only is about half of normal soil Confucius degree in the reasonable area of root system under hard the covering, has significantly changed the reasonable normal distribution of root system, has quickened the degeneration of root system undoubtedly.
2, soil gas
Oxygen content is significantly less than the content in the atmosphere in the soil.When the oxygen content in the soil was lower than 10%, the normal function of most of plant roots fell into a decline, and because ventilative difficulty often causes carbon dioxide poisoning, even death by suffocation.
3, soil moisture and mineral matter element wherein
The soil water is mainly derived from natural precipitation.In the area that hard covering is arranged, natural precipitation be difficult to infiltrate soil, and major part all rainwash has been fallen, and test learns that the soil moisture content under the hard covering has only about 12% the very natural normal physiological needs that just can't keep plant.
Various mineral nutrient elements only are dissolved in the water and become ionic state and could and be transported to the various piece of plant corpus by plant absorbing in the soil, because the reduction plant of water content can not get enough mineral nutrient elements at all.Soil density greatly also can make edaphon reduce, and the soil with organic matter decomposition is slowed down, and available nutrient significantly reduces in the soil, and is difficult to form granular structure; Particularly falling sharply of mycorrhizal fungi quantity causes hard covering area plant disease-resistant power to descend.
4, soil temperature
The test result explanation has mulching soil that the upper layer of soil temperature is raise, and the obvious no hard covering area of day and night temperature variation is little, makes butt and root be subjected to coercing of high temperature.When being higher than 35 degrees centigrade, its growth just begins to stagnate, so that stop growing fully.Hot daylight in the summer trunk of easily burning, very high surface temperature will strengthen its degree of burning.For the planting trees, because its root growth is incomplete, the top layer root system is more, more is subject to the influence of high temperature, makes its undergrowth, incidence of disease height especially.It also is one of reason that causes root system alcohols and acids poisoning that soil temperature increases.
Chinese patent " the plant roots filling water-saving cultivation method " patent No. is 97103541.5, proposed " again on the cloth every 1 meter hole of making a call to 6～10 centimetres of diameters " and seen the 1st page of 22～23 row of claims in the open text of application, in the specification of the open text of this application in the 13rd page of 17～18 row, point out " 7; the bag root is handled has the characteristics of root system pruning; add that the ventilation effect of input hole and the fermentation of organic root-wrapping material heat up rhizosphere; can cause root system flourishing rapidly; " this patent is when carrying out the root filling, also increased the air content in the soil, show that the air content in the soil has substantial connection to the normal growth of root system, punching diameter in this invention is worth for 6～10 centimetres using for reference, but hole knockout was too simple in should inventing, to the DeGrain of urban path tree.
To sum up, the physics and chemistry of urban afforestation land used soil is originally with regard to bad reality, because " transformation " of road, the progress of construction technology and the upgrading of pavement material, cause the structure of soil, composition, water content, temperature, gas permeability, great variation has all taken place in the activity of soil animal microorganism, make and formerly worsen more with regard to bad soil condition, caused thus having grown for many years in addition the trees of decades weak rapidly, hundred sudden onset of disease, quicken decline, also make the planting trees be difficult to survive, this phenomenon is along with the urbanization construction is accelerated, and this " disease " become new great " disease " that the city trees and shrubs plant protection faces.
Summary of the invention
The invention provides the fast quick-recovery of a kind of hole drilling ventilation method, improve the method for street tree root physiology function, to solve hard tree root depauperation down, the problem that the incidence of disease is high of covering in city.The technical scheme that the present invention takes is:
One, determine punch position, punch position should be chosen in and absorb Root Distribution close quarters, pitch-row 130cm～200cm each other under the tree crown;
Two, punching quantity: according to the tree crown size is in 200cm～600cm scope, punches 4～8;
Three, the punching degree of depth 30～150cm;
Four, the hole is vertical to can be, or from distance butt 50～100cm to the absorption oblique 45 ° of punchings in root system compact district;
Five, place corresponding filler according to soil physical and chemical property on the spot behind the pore-forming.
The invention has the advantages that: increased the gas permeability of the soil under the hard covering, helped the reasonable normal distribution of root system, prevented the degeneration of root system effectively; Increased oxygen content in the soil, and good permeability, made the trees can be because of anoxic death by suffocation; Improved the water content of soil, the hole of being beaten helps natural precipitation, manually waters and permeate the ground, and be diffused into the Root Distribution zone to satisfy the normal physiological needs of trees, moisture content abundance in the soil, just can better dissolve wherein each kind of mineral matter, make plant roots can obtain enough mineral nutrient elements; Help the reduction of soil temperature, the normal growth of the root system that protects trees physically well develops it, reduces the incidence of disease, prevents the alcohols and the acids poisoning of root system.
