It makes people be in nature rather than coming to super modern science and technology venues, so that tourists can truly relax and comfortable.

2. Common design techniques for garden landscape lighting

1. Landscape lighting lighting of water view

Water scenery is one of the components of the garden lighting project, and it is also the key lighting design part.There are many forms of garden water views. For example, there are large lake water views with wide water surfaces, as well as Fountains, streams, cement ponds, and waterfalls.The night scene lighting design method of the water surface lighting project is mainly reflected by the water surface landscaping and the railings on the shore and the lighting of trees on the water surface.Real views and reflection in water, compare each other, set off, positive and reflect, plus the dynamic landscape effect of reflection in the water, let people enjoy it.For some waterfalls and Fountain landscapes, underwater lighting can be designed, and underwater lighting fixtures of the same or different colors can be exposed through special arrangements according to demand. The effect of lighting is magical.

2. Landscape lighting of sculpture sketches

The sculpture sketch in the garden lighting project, the iconic construct, is very ornamental, and the latter is memorable.This type of lighting design should start with the main characteristics of the sculpture, especially the key parts of the sculpture, such as: head, material, expression, color and surrounding environment.The front of the front is uniformly illuminated, which can create a lighting effect of lighting, realistic, and strong three -dimensional sense.In the selection of light sources, a narrow beam lamp should be selected, and the main direction of the vision of tourists should be avoided to prevent glare.

In addition to being able to beautify the environment and provide tourists to watch, they also have the effects of regulating and protecting the environment.lighting should be treated according to the height, size, appearance characteristics and color of the trees.

1. Tea planting conditions

1. Soil

Generally, it does not contain lime stones with a thickness of up to 1 meter, and the sandy loam with good drainage is 1%-2%of the organic matter content. The permeability, water permeability or water storage performance is good. The pH value of pH is 4.5 ~ 6.5.

2. Rain amount

The average rainfall and the annual rainfall is more than 1,500 millimeters.Insufficient and excessive impact.

3. Sunshine

Light is the primary condition for the survival of the tea tree. It should not be too strong or too weak. It has special hobbies for ultraviolet rays.

4, temperature

One is the temperature, the other is the ground temperature, the average daily temperature needs to be 10 degrees; the minimum cannot be lower than -10 degrees.The average annual temperature is eighteen degrees to 25 degrees Celsius.

5. Terrain

The main terrain conditions include altitude, slope, and slope.With the rise of the altitude, the temperature and humidity have changed significantly. In a certain height mountain area, there are abundant rainfall, large clouds, large air humidity, and strong light.In more than 1000 meters, frost damage will be available.Generally, it is better to choose a south slope.The slope should not be too large, and generally requires below 30 degrees.

2. Points of tea planting

1. Soil

If you want to plant high -quality tea, the choice of the plantation place is the foundation.Generally, the soil of the planting place should be calculated from four to 5 to 6.5, which is a sore soil.Secondly, the soil structure of the planting site should be complete, the soil layer is deep, the soil fertility must be sufficient, and the organic matter content is abundant.Finally, the rich water source, water quality and soil must not pollute, convenient irrigation, convenient transportation and water and electricity, and the soil is red or yellow soil.

2. Water

The growth of tea trees is also relatively high in water, so we need to plan drainage and irrigation systems in advance.According to the terrain of tea planting, the layout is reasonably, and the arrangements such as roads, ditch, water pipes, and faucet are carefully done.The irrigation system of the tea garden is generally sprayed, which can not only save water resources, but also spraying irrigation methods is more conducive to the growth of tea.During the growth of tea, we need to irrigate frequently, but the amount of irrigation must not be very large, and the surface soil can have a certain humidity.

3. Nutrition

In order to promote the growth and renewal of tea, we need to properly top topical pursuit.The ribbon branches that are just planted for a long time need to be applied once in the spring, and the tea trees from two to three years need to increase the amount of topdressing, which is doubled in one year. Of courseNitrogen Fertilizer.Three years later, tea trees need to be picked up four times a year, including base Fertilizer, spring Fertilizer, autumn Fertilizer, winter Fertilizer, and leaf surface Fertilizer.

4, density

The density of tea planting is also a problem that we need to pay attention to when planting.Reasonable planting density is good for the yield and quality of tea.If the density of planting is too high, it is easy to occur in various problems such as dysplasia and uneven light.Then the spacing of the density of planting is about two meters and one meter between the plants.

5. Anti -frozen

We all know that the cold resistance of tea trees is very strong and will not die in heavy snowy weather, but this disease does not mean that it is not afraid of freezing.Pay attention to the treatment of cold and insulation during the young tree, otherwise it is also easy to be frostbite, which will affect the yield and quality after the tea tree.Then when the cold wave comes, we put some insulation materials around the tea trees, such as straw, which can have a good effect of preventing cold.

6. Pruning

Pouring tea trees is a very necessary job to grow tea.The tea gardens we see are basically consistent with the tree shape of tea trees, so as long as we prunites, we can keep them consistent, and only when trimming like this can the quality of tea growing tea leaves will be better.When necessary, we need to update the trees, that is, comprehensively update the tea trees to improve the quality and yield of tea.

3. Prevention and control of tea diseases and insect pests

1. agricultural prevention and control

Choose a variety of disease -resistant insects and enrich plants

Different varieties of tea have different morphological structures and biochemical components, so different varieties of tea are very different from the resistance of different diseases and insect pests.When planting tea trees, we should select good diseases and insects according to the specific situation of the local area to reduce the harm of pests and pests to the tea trees.

Tour and clean up the tea garden

Properly trimming the tea tree can not only regulate the trees, promote the increase in picking area, but also effectively reduce the occurrence of pests and insect pests.

Reasonable fertilization and picking in batches

The fertilization of the tea garden should be determined according to the results of the meter measurement to prevent the amount of fertilization, avoiding a large amount of nitrogen fertilizer caused by the weakening of the plant resistance.In addition to applying phosphorus and Potassium fertilizer, trace elements and organic Fertilizers should also be supplemented in an appropriate amount to reduce pests and insect pests.

2. Biological control

Treaty of the enemy

The natural enemy resources in the tea garden are relatively abundant. For example, bare -eye bees can control the density of pests such as cypress, scrusted winged, and wings.The control of natural enemies to control pests should be used to ensure the biodiversity in the tea garden as much as possible and ensure the living environment of natural enemies.

Bacterial prevention and treatment of diseases and insect pests

Bacteria are used in tea diseases and insect pests.Su Yunjin Bacillus can secrete a toxin. This toxin only infects some types of pests, and has no toxic effect on natural enemy insects and humans. The bacteria agent can be used in the tea garden to effectively prevent the occurrence of lumper -winged pests.Essence

fungal prevention and treatment of diseases and insect pests

The fungal biological pesticides in the prevention and treatment of tea diseases and insect pests mainly include white stalemate and wooden mold.

After contacting the pests, the spores of the White Strike can invade their mycelium into the body of the pest. In tea applications, pests such as tea poisoning moths and tea roll moths are well preventive.

Woodwood bacteria secrete antibacterial protein and other substances to inhibit the infection of tea leaves by pathogenic bacteria. At the same time, they can also inhibit the reproduction of pathogenic bacteria through spatial and nutrient competition.

3. Physical prevention

There are two types of physical control methods commonly used in tea gardens.

Artificial killing is a killing of pests in the tea garden in accordance with the growth law and characteristics of pests.

The deduction of appliances is based on the trend of pests, and the use of physical factors such as magnetic fields, odors, temperatures, or the color of the appliance generated by the appliances to induce killing insects, thereby reducing the density of pest density.
