Landscaping planting type and conservation measures China has the reputation of an ancient country in gardens. The gardens are intended to be used within a certain area to open up natural landscapes, combine the planting of plants and the layout of buildings, thereby creating an environment for people to watch, enjoy recreation, work and study, and live. Greening is an indispensable subject in gardens and refers to the planting of trees and flowers to improve the environment in addition to natural vegetation. With the in-depth development of reform and opening up, the enhancement of the country’s strength, the improvement of people’s living standards, and the need for spiritual civilization, the landscape of the country’s urban and rural units is changing with each passing day. There are Suzhou-Hangzhou gardens that are famous all over the world, Guilin natural landscapes and nails, the ancient capital of Beijing, and Xi'an. Today, there are reform and opening up special zones, Shenzhen, Xiamen, and Pudong, which are called modern garden cities. Landscaping work has continued to a new level. Garden-style and garden-style units, communities and schools have emerged one after another. This has not only beautified the environment, improved people's quality of life, but also provided a large number of employment opportunities. Nowadays, it is engaged in the expansion of the landscape greening and conservation team. Among these conservation teams, some graduates of agricultural colleges serve as technicians and landscape architects. Most of them come from job transfer, unemployed people, and agricultural workers entering the city. Raising the overall quality of conservation teams, popularizing conservation knowledge, and mastering key technologies are the keys to ensuring the consolidation of the effects of landscaping, the beauty, and the blooming of flowers. I. Landscaping Planting Types (a), forestry At present, the common types of trees for the greening of institutions and schools in southern China include trees and shrubs. There are deciduous and evergreen trees and shrubs. There are willow trees, eucalyptus trees (large leafhoppers, leafhoppers, alpine alfalfa, yellow geese, etc.), magnolia trees (white magnolia, yellow magnolia, lotus magnolia, etc.), eucalyptus (large leaf alum, acerola, lemon alum, etc.). There are also incense, man-made trees, kapok, cypress and so on. The greening shrubs include: Fujian tea, Huang Xinmei, Shanzijia, Changye, Camellia, and Laughing. In addition to Joe and shrubs, many units in the southern urban and rural areas use fruit trees such as mangoes, longan, and litchi as afforestation to serve two purposes. In addition, the high-end sub-tropical tree species, such as the flag tree species, rhubarb coconut, pseudo-betel nut, holistic sunflower, and brown palm, are not only planted in parks, but they are now the preferred green tree species in the institution schools. Above all kinds of trees, according to the requirements of the planning and design of the garden and the actual combination of units, according to the need to choose planting. (b) Grassland Grassland vegetation, the planting area in the unit greening is larger, planted on the ground for the square lawn, planted in the slope wall and the hill Qiu is grass qiu (grass hill). Grassland vegetation, soil and water conservation effect is good, will not be exposed to loess, green meadow makes people feel good. At present, grass species such as Taiwan grass, big leaf grass, and coniferous grass have been used for the southern units and schools. Taiwan grasses grow fast, have dark green leaves, uniform and delicate leaves, and have good viewing effects from far and near. They should be planted in front of the building's gate and empty areas. Large-leaved grasses are resistant to drought and stubble, large leaves, good coverage, farsightedness, and poor viewing. It should be planted on slopes, mountains and corners. The coniferous grass leaves, hard stems and small stems, pod growth, drought tolerance, resistance to trampling, strong vitality, but the poor viewing effect, should be planted in the easy stampede and sloping land. (c) Green Grasshoppers Green grasshopper is an indispensable planting type in the garden of the unit. It has both ornamental value and is an isolation belt beside the roads between regions. The common green grasshoppers in greenery are flat green grasshoppers, garden green grasshoppers and modeling (or wording) hedges. Three kinds. The tree species often planted in these hedgerows are: Shanzijia, Fujian tea, Huang Xinmei, etc. The shanzijia is crude and easy to grow, and the leaves are dark green, which is suitable for high hedges in the plane; Fujian tea is long and rough, and the leaves are dark green, so it is appropriate to use them. Near the wall hedge; Huang Xinmei crude, yellow-green leaves, easy modeling, good ornamental effect, often used in modeling hedge. (four) flowers, bonsai Flowers are the essence of gardening and planting types, both potted and locally grown, divided into herbs and woody trees, as well as yin-yang and indoor and outdoor planting. As the name implies, flowers are mainly flowers. In the process of greening, different types of different varieties are planted. Artificially, the flowering period can also be adjusted so that the flowers bloom in the whole year. Herbaceous flowers commonly used in greenery are red and green grasses, and are brightly colored. They are often used for planting patterns. In spring, they are suitable for three-dimensional greening, as well as violet orchids, a bunch of red, peony, canna, lily, chrysanthemum, jellyfish, and paper popcorn. Gypsophila grass, a hundred years of love and so on. Woody flowers are: Azalea (Bougainvillea), camellia, smiling, plum, apricot, sweet-scented osmanthus, big safflower, dragon vomiting beads, golden osmanthus, silver silk flowers and so on. The shade plants suitable for indoor cultivation include: Brazilian iron, green grasshopper, flower butterfly, monstera, green bully, fortune bamboo, money tree, money tree and so on. Bonsai is a fine art of plant art. In the unit of landscaping, the tree groves are often used for landscaping. Choose the right material, according to the characteristics of plant growth, combined with artificial art modeling, it is the most small piece of garden view and landscape. Second, the technical measures of green conservation In the cultivation science, it is often said that “three kinds of plants are planted in seven tubesâ€. Plants in the planting process are all living plants. When the landscaping is carried out by many units, they tend to have high standards for planning and design, and the construction maintenance is low, resulting in a long period of time. In the management of greening and conservation, it is necessary to understand the special characteristics and characteristics of planting types and various varieties, and to focus on the maintenance and management of fertilizers, water, diseases, insects and cuts. (I) Grassland Conservation Management Grassland conservation principles are: uniform, clean and free from miscellaneous, evergreen seasons. According to information, green grassland (Taiwan grass) under the general management level can be divided into four stages according to the length of planting time. One is the stage of planting to maturity, which refers to the initial planting of grassland, planting to a stage of one year or full coverage (100% full and empty land), also known as the overfull period. The second is the prosperous stage, referring to 2-5 years after planting, also known as prosperous long-term. The third is the slow-moving stage, which refers to 6-10 years after planting and is also called slow-moving. The fourth is the degradation stage, referring to the 10-15 years after planting, also called the degradation period. Under the higher conservation and management level, grassland degradation in Taiwan can be postponed by 5-8 years. The degradation period of L. chinensis is 3-5 years later than that of Taiwan grass, and that of L. oleifera is 3-5 years earlier. 1, Recovering the management of the overfull period According to the design and process requirements, the newly planted grass bed should be strictly cleaned of weed seeds and grass stems, and filled with pure land and dirt to compact more than 10 cm to stick turf. There are two kinds of turf: First, the whole paste, the second is thin paste. Thin paste 2020 centimeters square turf and other areas left empty paste, all paste no overtime, only recovery period 7-10 days, thin paste 50% of the space to take some time to get full, spring stickers and summer stickers The turf is over 1-2 months short of the turf, and it will take 2-3 months for the fall stick. In terms of maintenance and management, it focuses on the management of water and fertilizers, applying anti-staining in spring, sun-blocking in summer, and applying wind and moisture in autumn and winter. Generally, spray water once in the morning and evening after plastering, and check whether the grass is compacted and require grass roots to tightly cover the soil. After spraying, spray water once a day in the evening or two weeks. After two weeks, spray water once a day or two depending on the season and weather conditions. After fertilization and planting, the fertilizer is applied once every half month from the beginning of one week to three months, and then sprayed with 1-3% of urea solution. The mixture is diluted and concentrated. After that, 4-6 kg of urea is used once a month for a month. , Sunny liquid, all covered with grass height 8-10 cm, using a lawnmower to cut grass. In addition to weeds, as early as half a month after planting, and as late as January, weeds began to grow. We must dig the grass in time to remove the roots, dig and compact them, so as not to affect the growth of the main grass. The newly planted grassland is generally free from pests and does not require spraying. In order to accelerate the growth, it can be sprayed with 0.1-0.5% potassium dihydrogen phosphate water in later stages. 2. Prosperous management The second year to the fifth year after planting grassland is a vigorous growth stage. The ornamental grassland is dominated by greenery, so it is important to keep green. Water management, open grass stems, soil is not dry white, wet and not stain, spring and summer dry in one year, autumn and winter wet principle. Thin application of light fertilizer, 4-9 months less in the year, more than two, after each mu 2-4 kg of urea. Prosperous season, to control the fertilizer to control the water speed, otherwise the increase in the number of mowing, maintenance costs increase. Grass cutting is the focus of work at this stage. The number of grass clippings and the quality of grass cutting are related to the cost of grassland degradation and conservation. The number of mowing is controlled at 8-10 times a year, and it is cut once a month from September to September, and once every month from October to January. Mowing technical requirements: First, the best viewing height for grass is 6-10 cm, more than 10 cm can be cut, more than 15 cm, it will play a "grass pier", part of the hook shape, this time must be cut. The second is to prepare before cutting, check the power of the lawnmower to be normal, sharp grass blade without defects, at the same time detect the net turf debris. The third is the lawnmower operation, adjust the knife distance, 2-4 centimeters off the ground (prosperously low cut season, high cut in autumn and winter), uniform speed advance, cut each 3-5 cm of cutting, do not miss cutting. The fourth is to timely clean grass leaves after cutting, and moisten fertilizer. 3, the management of prolonged period In the grasslands 6-10 years after planting, the growth rate has declined, and the dry and dry stems have been increasing year by year. Root rots are prone to occur in the hot and humid seasons. Autumn and winter are vulnerable to the groundworm (Schizoneperidae). Prevention of pests and diseases. According to observations, Taiwan grass has been continuously rotted for three days after waterlogging, and there is still vitality after draining the water. Continuous waterlogging has occurred for seven days, and more than 90% of rotted roots have almost no vitality and need to be re-stitched. Although waterlogging is less than 1-2 days, it is prone to germs after drainage, which causes root rot to occur. With thiophanate or carbendazim 800-1000 times, spraying 2-3 times (spray once every 2-10 days), the effect of controlling root rot is good. Old-age tigers (shaved worms) cut the base of the grass at the surface to form blocks of dry and dry, the area of ​​which is expanding day by day, causing rapid damage and causing large areas of dryness. During the inspection, the grass must be removed to find the larvae. To early detection and timely use of drugs in the youngest larvae, usually with methyl disulfiram or 800-fold speed culling, increasing the liquid harm, three days after the clearing of the damage of the withered grass, and additional urea solution, began to recover after a week . Slow and long-term management of fertilizer and water should be strengthened in the long-term, and extra-root fertilization can be added. The number of times of mowing is controlled 7-8 times per year. 4. Management of grassland degradation stage Ten years after planting, the grassland began to degenerate year by year and was severely degraded 15 years after planting. Water management, dry and wet high, no waterlogging, otherwise exacerbate the root dead, strengthen the inspection and control of pests, in addition to normal fertilization, every 10-15 days with 1% urea, phosphorus dipotassium mixed solution root, or use Foliage protection, foliar fertilizers such as large Toyota outside the root of spraying, the effect is very good. Completely withered can be done locally. Fei County Mingtao Electronic Co.,Ltd , https://www.yourbeautyassistant.com
