Landscape trees can also be planted in the roadside, poolside, porch, pavilion before and after or with the rocks, buildings, etc., or in small local scenic spots in groups of three or five scattered planting everywhere, the formation of a natural interest of the arrangement, can also be in the regular layout of the axes of the region for the regular style with.
Landscape tree pest control methods
(1) powder spray method. Through the powder sprayer will be powder toxic agent sprayed on the tree or pest body surface, so that the poisoning death. This method is highly efficient, does not require water, the trees themselves are less harmful; disadvantage is that the toxic agent in the trees on the body of the poor persistence, the dosage is large, the economy is not cost-effective.
(2) fumigation. The use of toxic gases or vapors, through the respiratory organs of pests into the pest body and kill pests.
(3) Spraying. The use of solution, emulsion or suspension of liquid toxins, with the aid of spray equipment to form a fine mist sprayed on the tree or pests.
(4) poisonous weed bait. The use of solution or powdered toxic agents and bait to make a mixture, and then scattered in the pests occur or live in the place.
(5) poison ring method. Toxicity will be applied directly to the bark of the tree or coated in tightly wrapped in the trunk of the paper tape or grass handle ring, to prevent or kill leaf-feeding insects climbed to the tree for damage.
(6) winter pest control can be used to dig nymphal insects, scraping bark and other methods to eliminate a variety of overwintering insect sources. Painting the trunk white can eliminate the overwintering pests in the crevices of the bark.
Landscape tree transplantation method
(1) tool preparation
30T above the crane and 20T above the lengthening delivery truck each one, grass ropes and some digging tools and so on.
(2) Irrigation
Irrigation should be carried out about 5 days before the transplantation, watering sufficiently thoroughly, so that the seedling's root branches and trunks have enough water to make up for the lack of water absorption caused by the root system during the transplantation process, and the soil is easy to excavate after filling with sufficient water, and easy to form a soil mass.
(3) winding dry
Two days before digging, the grass rope soaked with water, from the base of the trunk of a circle close to a circle upward winding, the main role is to keep warm and moist. First, to avoid direct sunlight and transportation, planted to prevent dry wind blowing, reduce the trunk of the water evaporation; second is to regulate the humidity of the trunk, to reduce the transplantation of the temperature difference on the trunk of the injury; third is to wrap the rope parts of the water can be stored a certain amount of water, so that the trunk as much as possible to keep wet; fourth is to protect the large trees in the excavation and transportation of the tree planting from mechanical damage. In the crane rope lifting at the application of used car tires will be wrapped around the trunk, to prevent the trunk by the wire rope in the lifting damage.
(4) pruning
Pruning is the main measure to maintain the balance of the above-ground part of the large tree transplantation process, generally deciduous trees and conifers can not be pruned, for evergreen broad-leaved trees, the first to cut off the branches of pests and diseases and too dense cross over the long branches of the dry branches.
(5) orientation
Orientation is the branch with paint labeled with the north-south direction, so that in the transplantation can still maintain its original direction to meet the requirements of its light.
(6) Excavation
The key to large tree excavation is to protect the ball of soil does not fall apart, generally the diameter of the ball of soil with the trunk diameter of 810 times, the height of the ball of soil for the diameter of 70% or so, the ball of soil is too large easy to fall apart, the ball of soil is too small is not easy to survive. Excavation of the appropriate increase in the excavation area, from the inside to the outside to form a certain slope, to be determined by the diameter of the downward excavation, fixed to be vertical, up and down the width of the same barrel shape.
(7) soil ball trimming and packaging
Earth ball dug with a sharp hoe or shovel, will be trimmed smooth, soil ball below to be trimmed into a small flat bottom, trimmed to be soil ball bandaging. Earth ball bandage first with wet grass rope, the earth ball horizontal waist winding, the width of the earth ball 1 / 3, and then the grass rope tied to the trunk, up and down cross around, into a net. Twisting should be forceful, bundle solid, minimize joints, and tie the rope head tightly at the root of the tree. Then cross-wrap the soil ball with coarse twine.
(8) lifting
When using a crane to lift a large tree, it can be lifted and loaded directly onto a car. The car with 40cm thick straw bottom, to prevent the earth ball and car steel plate direct contact, damage to the earth ball. When loading the earth ball towards the front, the tree back flat on the car, in order to prevent the earth ball rolling, can be fixed with stones; in the trunk of the car in contact with the stop plate, and with used car tires and twine fixed. After loading the car with twine to the trunk for multi-point winding, fixed in the car. The car should be transported to the designated nursery for planting immediately after loading.
Feng Shui Analysis of Planting Landscape Trees in Gardens
(1) Selection of Tree Types
There are choices for planting trees in yards. Feng Shui believes that plants are divided into two categories: the fierce and the lucky. There are two criteria for the division of the fierce: one is to be divided by whether there is poisonous gas, venom as the standard, which has a certain scientific basis. If some scholars believe that nightshade evening will emit a large number of strong stimulation of the sense of smell particles, heart disease and hypertension patients have a negative impact, oleander flowers are poisonous, the fragrance of the flowers easy to make people drowsy, reduce the function of the human body, tulip flowers have soil alkali, too much contact with the hair is easy to fall off, etc., is a vicious tree, should not be planted in the courtyard. The second is the shape of the tree to discuss the bad luck, such as "big tree odd, gas pain in the name of defeat", "tree flexion hunchback, Ding Cai all retired", "tree like a volcano, snail disease," and so on. Where the appearance is not square, dignified, the development of abnormal trees is bad. I am afraid that this is a psychological effect or the traditional concept of humanistic aesthetics at work. As for the auspicious tree, it is based on plant characteristics, symbolism and even harmonies to determine, and real life people tend to agree with this point of view, such as feng shui scholars believe that the palm, orange tree, bamboo, tsubaki, acacia, osmanthus, ganoderma lucidum, plums, ficus, jujube, pomegranate, grapes, begonias and other 13 plants for the auspicious plants, peach, willow, ai, ginkgo, cypress, cornelian, no need to be affected by the child, gourd, and other 8 kinds of plants have to turn the evil spirits to drive away evil spirits, as people Recognize this point of view, we should be referred to in the garden design.
(2) planting direction
Ancient Feng Shui classics have some assertions: "East planting peach and poplar, South planting plum and jujube, West planting mast elm, North planting Ji Li," "the door in front of the weeping willows, is not auspicious! ", "in the door of the acacia, rich hobbies three times", "the house behind the elm, a hundred ghosts do not come close", "the door in front of the court like to plant double jujube, the four sides of the bamboo and wood verdant into the wealth". "The corners of the house have Samson, the time of trouble can not file", and so on. From the above assertions, combined with modern scientific knowledge, we believe that some assertions contain knowledge of natural sciences, some are a psychological need to avoid disaster, such as the east planting peach and Yang because the east is the first to meet the sunrise, willow germination is relatively early in the plant, the peach blossom is one of the earliest flowering plants to welcome the spring, so planted in the east is reasonable, elm is a wet-loving plants, when the west is not afraid of sunshine, planted in the west is appropriate. As for the said acacia tree attracts wealth, elm tree to drive away ghosts is likely to have many superstitious elements, willow tree should not be planted in front of the front door, may be referred to as the willow tree, "poplar", so it is difficult to accept from the psychological point of view.
(3) the number of trees planted
Feng Shui advocates a reasonable and dense planting. It is believed that: around the situation of the Bureau of the shape of the big narrow, not more trees, otherwise it will help its Yin; only in the back of the left and right place there is open, it is planted in order to barricade its empty. We agree with this view, but some of the following statements are superstitious color is too heavy, we can discard: "a single tree when the door, widowed mothers and orphaned grandchildren," "the door to the forest, the sudden disease, more fierce," "two trees in front of the door, the animal injury to the better! ", "left tree right no, less good luck and more bad luck", "left tree three or five, husband and wife are incompatible", "two trees sandwich house, will be lost flesh and blood", "A single tree Pingxiu, the two surnames do not get along", "the left tree heavy obstacles, prosperity".
(4) tree size
On the courtyard planted how big tree is more appropriate, different schools of feng shui have different requirements: feng shui in the form of the school that to block the home around the brake, it is desirable to rows of planting large trees. To add to the needs of the situation, in the house built in the plains or around the relatively wide place, available trees and plants to create a "left dragon, left white tiger, before the Zhu Bird, after the Xuan Wu" of the four gods of the pattern, that is, behind the house planted large trees, left and right sides of the planting of medium-sized trees, planted in front of the front of the low shrubs or planting of grass, this way of aesthetics is not to be faulted, and This way from the aesthetic point of view is not wrong, and in line with the psychological needs of people looking for "feng shui", we can participate in the application of the design. Feng Shui in the school of gas that it is appropriate to see the high place to plant large trees, it is appropriate to see the low place to plant low plants, such as the eight mansion tour of the theory that the house of the sky doctor, Yannian, angry side of the tree should be planted in the other direction of the planting of short trees or grass; XuanKong law stipulates that the positive god can be planted in the large trees, and zero god direction is not appropriate, this method may not have any scientific basis, and does not seem to have some aesthetics on the beauty of it, we unless the construction party has special requirements, otherwise it is not appropriate to The construction side has special requirements, otherwise it should not be used as a reference.
(5) tree type selection
Feng Shui theory in general advocates square garden, symmetrical and balanced, and thus in the plant cultivation of the overall requirements can be summarized as follows: healthy and no disease stakes, dignified and demonic, we can see this from the following feng shui assertion. "Strange tree swollen head not swollen waist, evil and lewd little ghost demon", "bamboo trees hanging down at the water's edge, children fall into the water unbearable", "dead trees when the door, fire death", "Tree branches entangled in the vine, hanging beams overboard", "Tree damage to the lower side, foot disease side Mian", "Fruit tree branches left, miscellaneous diseases, phlegm and fire", "Tree under the swollen roots, deaf, blind and sick fainting "," oblique branches to the door, weeping soul", "large trees, odd, gas pain in the name of defeat" and so on. Can be sure that the dead trees, dead trees, sick trees should not be planted is correct without a doubt, as for the appearance of the tree is not dignified should be looked at in two, there are trees due to the beauty of the curve, due to the flexure and the good, we can not be generalized exclusion; of course, the curve and ugly, twisted and poor, we will not be planted.
(6) plant color selection
Classical feng shui books directly on the color of plants is not common, only a few sentences, such as "the right tree red flowers, charming pouring home", "the right tree, white flowers, children and grandchildren zero drop! ", the right tree red flowers, I'm afraid with the "peach blossom luck" related to the theory that it and the pond should not be located on the right, otherwise there will be obscene phenomena is the same. The "white flower on the right tree" is related to the custom of mourning for the dead with white flowers, so the judgment of "zero grandchildren" was made. We think that this judgment is nonsense, otherwise the white and flawless magnolia planted in front of the house would be a taboo? Although the ancient feng shui theory of planting what color plants do not have specific, too much discussion, but feng shui theory that everything in the world by the "gold, wood, water, fire, earth," the five material elements, and different colors are representative of different elements.
Gold - white, apricot, gold
Wood - cyan, green
Water - black, blue
Fire -- red, purple
Earth -- yellow, brown
As for what directions and places are appropriate to plant what color, feng shui according to the principle of the five elements of mutual reproduction, creating a series of complex theories, limited to space, we do not We will not discuss. Modern some new feng shui scholars, according to the psychological customs of people on the color, put forward some new ideas, they think: red on behalf of the red fire, warm; green on behalf of peace; yellow on behalf of the rich; black on behalf of the solemn; white on behalf of clean, solemn. We can refer to the application in the garden design.
