Grapes are very adaptable to the environment, resulting in early, simple management techniques, easier to cultivate than ordinary Qiaohua fruit trees. Therefore, grapes are not only suitable for cultivation in mountainous areas, floodplains and plains, but also can be cultivated in gardens behind houses in front of towns and rural houses. This is one of the ideal tree species to beautify the environment.
Autumn Base Fertilizer: Grape is a kind of tree that is very good for fat and water, and base fertilizer is the most important link in the management of grape manure. Basal fertilizer can be applied in the autumn or spring, but the autumn application is better than the spring application. There are many kinds of autumn basal fertilizer, such as human urine, cow dung, pig manure, sheep manure, chicken manure, etc., but it must be decomposed and fermented first, and no manure should be applied, so that it will not be applied to the soil. Bad influence. The amount of basal fertilizer should mainly consider the results of the amount of fertilizer types and other factors. General cow dung, pig manure and sheep manure are applied at a rate of 1 kilogram per 0.5 kilogram; human feces and urine and chicken manure are high in nutrient content, and can be applied at a rate of 0.5 kilogram per 0.5 kilogram applied. Fertilization method is best to take radial groove, depending on the age of the tree, the amount of fertilization depends on the number of fertilization ditch, length, and the depth of fertilization from 20-40 cm from shallow to deep is appropriate.
Winter pruning: There are many grape pruning methods. The specific method to be adopted should be determined according to the cultivation type. It is advisable to use the dragon dry shape pruning method for grape cultivation in the yard. The dragon has a dragon, two dragons, and many dragons, depending on the size of the courtyard space. The space is small and one dragon is used. The space can be used to form two dragons and three dragons. The specific reshaping method is: after winterization, the grape will be cut 50-60 cm long each year after winterization, 3-4 vines will be left after budding in spring, and 50-60 cm short cuts will be propagated during autumn winter cuts, while the lateral growth will be 2-3. The festival is limited to a maximum of 3-4 knots. It is advisable to leave one lateral vine on each side of the year, and don't use it as a means of cultivation. According to the length of the shelf through 4-5 years repeated pruning, when the extension of the truss from 50-60 cm at the end of the plastic work. Lateral vines adopt two renewal pruning methods, cutting the buds to leave 4-6 short cuts during the winter cut, and the second shoots for 2-3 short cuts. After the spring sprout, cut 2-3 shoots on buds and 2 shoots on second shoots. If the two shoots of the second bud have a thickness of 0.6 cm or more in winter, the two shoots will be two. The first tip of the tip leaves a short section of 4-6 knots, and the second tip leaves a short section of 2-3 knots, while the first bud tip 2-3 results are completely removed by shrinking. If the result of the second shoot is less than 0.6 cm thick, remove weak shoots and strong shoots, and leave 2-3 stanzas. Pick a new shoot from the first shoot and leave 4-6 knots. Short cuts, others sparse. It is pruned year after year, that is, it shows a dragon dry shape, and a refreshing ring is formed every 40-50 centimeters on both sides of the dragon stem to form a reasonable scientific plane, laying a foundation for stable production and high yields every year.
Clean pastoral garden grape often because of management is not in place, fruit, leaves often become infected, diseased fruit, leaves fall under the frame, but also some weeds breeding, it is wintering place for grape diseases and insect pests. Therefore, it is necessary to clean the pasture before planting and burying the soil to prevent the cold. The diseased fruit, diseased leaves, and weeds will be buried in depth so as to reduce the sources of infection and pests in the coming year.
Buried in the cold: grape roots at minus 6 °C -7 °C, branches, buds at minus 20 °C will be subject to freezing injury, in order to protect the plants safe winter, Beijing must be buried to prevent cold. The specific method is:
In late October to early November, the grapes are trimmed and then put on the shelf. The dragon stems are tied around the stems and tied around the stems. The bundled vines become tighter and finer. The one-on-one plants are finer and the two dragon plants are bundled. The body is thick, and the three dragons are thicker. According to the length of the plant body to dig equal length of the buried ditch, the width and depth are the same as the thickness of the bonded plant body. Put the body of the plant into the ditch buried with a depth of about 20-30 cm. The soil should not only be raised above the ground, but also be more than 20-30 cm above the ditch to prevent rain and snow from pouring into the ditch. Bring adverse effects. Then make a photo with a shovel to make it airtight.
Frozen water: When the temperature drops to about 0°C, the ground water begins to freeze in the morning, and the land has not yet frozen and begins to freeze the water. The Beijing area should be in mid-November. The frozen water must be filled and the day should be fully exposed. The surface of the ground should not contain water or ice.

What problems should we pay attention to when using solar energy for power supply?
1. The whole day sunshine time of monitoring points along the expressway shall be considered first. As the main energy of the power supply system comes from sunlight, the sunshine exposure time must be considered, which is particularly prominent in mountainous areas where there is little sunshine, but not in plain areas.
2. Working power, working voltage and current of monitoring facilities along the expressway. After considering the power of the whole load, we can choose the solar panel that is more suitable for the long-term operation of the equipment.
3. If the battery discharge cannot make the monitoring equipment work for a long time, the monitoring system will be paralyzed in the rainy season, but the expressway is prone to accidents in the rainy season.
4. The conversion rate of solar cells is low. At present, the conversion rate of solar cell power supply is only about 20%, that is to say, if the silicon solar cell is spread over a square meter, 100~200W of power can be obtained, which is obviously not enough to meet the long-term operation of the monitoring equipment. Of course, with the development of technology and the improvement of the quality of crystalline silicon cells, we can obtain more power resources in a smaller area in the near future.
