1. Spraying, insect repellent, summer warm and wet weather is conducive to the invasion of pests, especially winged locusts and red spiders in the surrounding vegetable gardens and corn fields will successively migrate back to the peach trees to mate and lay their eggs for winter. The adults cluster in the back of the peach leaves. Absorb juice, make the leaves yellow and curl, seriously affect the growth of peach. Can generally be sprayed 5% carbendazim 800 times or 5% Kedan Dan wettable powder 50 times and other control.

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

Second, to prevent prosperous nectarine easy to pump the second branch or even three branches, coupled with the nectarine power, especially before the results of the leggy. In the production should pay attention to control, the main measures for control are: 1 to strengthen the control of fertilizer and water. In particular, the control of nitrogen fertilizer, in the annual growth period and after fruit picking, cut too much nitrogen, in order to prevent booming shoots. 2 application of dwarf growth hormone control. In the shoot growth stage, 5 g of 15% paclobutrazol per tree under the tree ring groove or 200-300 ppm of paclobutrazol was sprayed on the tree, and the control effect was better. 3 to promptly wipe buds. For useless secondary branch, tertiary branch and back bud should be promptly erased. If the eradication is not timely, branching should be done in time to maintain good canopy permeability. 4 Maintain the uniaxial extension of the branches to reduce the number of branches.
Third, thinning and fruit thinning Because of the high fruit setting rate of nectarine, if the thinning and thinning of fruit on the production cannot keep up, it will cause the fruit to become smaller and affect the commodity quality of the fruit. Therefore, strict sparse fruiting should be adopted in production. According to the result of the growth of the fruiting branches, the sparse fruit should be sparsely flowered in the early flowering period, and 4 to 6 flowers should be kept for each branch of the strong branch, 2 to 3 fruit should be kept, and 2 to 4 in the middle branch. Flowers, guarantee 1 to 2 fruit, short branches and bouquets of branches to stay double flowers, insurance results, to ensure that the tree leaves about 120 square meters of fruit in order to facilitate the full expansion of the fruit, improve the fruit of the commodity.
Fourth, to promote coloring Because nectarine tree is prosperous, branching can be repeated several times a year. If the control is not effective, it can lead to poor coloration of the fruit, especially the shade of the canopy and the lower canopy. Therefore, measures should be taken in production to promote coloring. 1 Reflective film on the ground floor to improve the use of reflected light. 2 In the budding period, the buds should be eradicated in time, and the second and third branches should be cut off in a timely manner in the growing period to control the amount of branches and prevent the deterioration of light. (3) The “丫†font, which is susceptible to light and Lifeng, should be selected as the main tree. 4 At the beginning of fruit coloring period, the light-shielding leaves were removed and the fruits were fully exposed. 5 In the period of fruit coloring, pull-tree treatment is carried out to increase the amount of light received in the canopy.
Fifth, enhance the flavor of nectarine production tends to appear lighter phenomenon, the main reason is due to excessive water supply or fertilization is irrational and early harvest caused by, and ways to increase the flavor are: 1 limit the water supply. Especially during fruit enlargement, if it is not too dry, do not apply water easily to increase the accumulation of substances in the fruit and increase the fruit flavor. 2 increase the material supply, especially increase the application of organic fertilizer, promote the accumulation of sugar in the fruit, make the fruit more sweet. 3 To harvest properly. In the beginning of the fruit coloring period, the fruit begins to enter the period of nutrient accumulation. The longer the fruit is put into use, the more nutrients accumulated, the more fragrant the fruit is, and therefore it should be timely harvested.
Sixth, the high surface light price due to nectarine hairless, fruit rust can easily infect, fruit rust occurs, reduced commercial quality, affecting the improvement of production efficiency. 1 Strictly control the amount of branches, keep the park open, reduce the air humidity in the park, and suppress the occurrence of diseases. 2 fruit bagging for fruit protection. 3Protection of chemicals, in rainy years, when the humidity in the garden is large, 25% of wettable chlorothalonil powder 2000 times or 65% of temperature-sensitive zinc powder should be promptly sprayed to 500-600 times of liquid. Keeping the fruit surface clean and improving the commercial quality of the fruit should generally be sprayed and sprayed with the above-mentioned pesticide every 7 days or so to control the hazard.

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.
