Selection of improved species The selected strawberry varieties should be adapted to the local soil and climatic conditions and have a strong resistance to pests and diseases. The main species I selected was Fengxiang, which was planted with a small amount of Mingbao varieties. Breeding seedlings 1, the establishment of special breeding Miao Tian. Select paddy field with convenient irrigation and high soil fertility, so as to divert water and drought timely in high temperature and dry season, reduce ground temperature, and ensure the success of nursery. Sprinkle 50% phoxim 0.5 kg or 3% carbofuran 1 to 25 kg mixed soil 25 kg per acre to control underground pests. 2. Transplanting seedlings. On April 15-20, when the average daily temperature is around 15°C, the seedlings will be planted in the field. The wide-leaved rice field is 2 meters wide, and one row of seedlings is planted in the middle of the hoe. Plant spacing is 0.8 meters, and 416 plants per acre are planted. About 100 strains of seedlings can be planted per plant. The time for the prosthesis is from the end of July to the beginning of August, and the seedling age is 45-50 days. The distance is 12cm 15cm, covered shade net after planting. Regularly remove buds to reduce nutrient consumption. In this way, generally there are 35,000-40,000 strains of strong seedlings with more than 4 leaves per acre, and about 5 mu of field can be transplanted. 3, Fan Miaotian management. Each acre of breeding seedlings is used to compost 1000-1500 kg of pig ash and 20-25 kg of superphosphate as base fertilizer. After the plants lived, 1 diluted fecal water was applied, and 5 kg of urea was applied every 10-15 days. In case of high temperature and drought irrigation, keep the soil moist. 10 days after planting, with pyrethroid pesticides or 40% oxidative Fruit 1000-1500 times alternately control disease 2 times, every 7-10 days with 50% carbendazim or 70% thiophanate-methyl 800-1000 times liquid 2 times. Manual weeding 2-3 times. Precocious high yield cultivation 1, colonization. Before planting, per acre applied to compost pig manure 2000-2500 kg, rapeseed cake 50-75 kg, potassium sulfate compound fertilizer 30-40 kg, superphosphate 30-40 kg as base fertilizer. The colonization time is September 5-15. Ridge width 1 meter (even ditch), height 30 centimeters, 2 rows per ridge, each greenhouse is planted with 6 rows and 12 rows of strawberries, each acre Density of 7500 strains. After 7 days of planting, when the heart of the strawberry is bright, 500-750 kilograms of diluted manure water or 2.5-4 kilograms of urea is applied to water 1-2 times. 2, early prevention and treatment of pests. Try to choose bio-pesticides, high-efficient and low-residue pesticides. If connected Continued 5-7 days of rain, the evening with Suo Keling fumigation agent to control gray mold 1-2 times, to ensure that the fruit quality. 3, using drip irrigation technology. Drip irrigation technology is mainly used in the middle and late period of strawberry water control. The use of traditional furrow irrigation methods can lead to high humidity in the field. Using drip irrigation technology can save water and ensure no pollution. 4, put peaks and sparse fruit thinning. Artificially assisted pollination and a method of placing a bee in each greenhouse. Can improve pollination rate, fruit rate and increase production. The axillary buds, old leaves, diseased leaves and stolons, high-order flower buds, small fruits, and a few deformed fruits were promptly removed. 5, temperature and humidity control. Before the end of October to November 5, cover the greenhouse film and plastic film. Before and after budding, the temperature in the greenhouse during the day is maintained at 25-28°C, the fruiting period is 24-26°C, and fruiting period is 20-24°C. The humidity in the booth is controlled within 70%. If the humidity is too high, it should be properly ventilated at noon on sunny days. 8-9 am, strawberry When the heart leaves do not spit water or when the mulching film is lifted on the top of the ridge, it drops water when the topsoil is white, which can not only control the occurrence of diseases, but also facilitate normal pollination during flowering. 6. Ditch the grass. At the end of November, 150 kg of fresh dry straw are placed in the furrows of each greenhouse, 500-600 kg of organic fertilizer is applied to increase the temperature of the furrows, and the carbon dioxide gas fertilizer is slowly released. This can increase the temperature in the shed by 1.8-2°C. , To increase strawberry yield and disease resistance, and promote fruit ripening. 7, timely harvest. In the winter or early spring, when the fruit is ripe and the color of the fruit surface is more than 90%, it is harvested. At the end of March of the following year, it is appropriate to harvest when the fruit is mature.
The Network CCTV Wireless Security Camera
Compared with wired cameras, wireless security cameras are less invasive to your home, so they are easier and faster to set up. No need to drill through walls or ceilings. Wireless cameras are also more flexible than wired systems because they are not as constrained as wired systems.
The biggest disadvantage of a wireless Camera System is that it is completely dependent on the strength of your Wi-Fi connection. Any interruption or weak signal can mean that you may lose connection to the system, resulting in the loss of the film, which can be critical

The working principle of the camera is to reflect the light to the sensor, convert the signal captured by the sensor into a digital signal, and finally send it to the computer to display the image. Then the camera can capture the static and dynamic images in the picture.
The sensor of the camera is the most important part. It can capture light and convert it into electrical signals. There are many types of sensors, the most common are CCD and CMOS sensors, which can be used to capture images.
The internal circuit of the camera will convert the signal captured by the sensor into a digital signal and send it to the computer. The computer uses these signals to display images, or it can save images to the hard disk drive.
If the camera is not connected to the network, it will not be able to achieve real-time monitoring, but the camera will still work and save the pictures and videos taken. If we need to view, we can only remove the memory for viewing.
