First, timely harvest: sweet potato harvest is too early, the yield is low; harvest too late, susceptible to freezing, affecting storage. Therefore, it is generally best to start harvesting at a temperature of about 18 ° C. When the temperature is above 10 ° C (that is, before the frosting period), the harvest is completed. Second, the selection of potato chips: When harvesting and selecting good sweet potato varieties, we must carefully plan to avoid trauma. In order to produce more seedlings, produce strong seedlings and reduce costs, we should choose potato chips with 150-200 grams of roots for seeding. The selected potato pieces should be disease-free, harmless, and have the typical characteristics of this variety. When harvesting, it is best to cut the morning, collect the plan in the morning, and enter the afternoon. 3. Storage in the sputum: Store in large eaves or mantle. Strictly sterilize the old scorpion before entering the sorghum. For example, spray the melon with 50% carbendazim 600 times solution or 5% amsame toxic water agent 500 times solution.窖 disinfection. When storing sweet potatoes, every time you store a layer of sweet potato, spray it evenly with the “sweet potato insurance agent†dilution. The special management measures for storing sweet potato in Dawuyu are as follows: the potato seed is in the early stage (15 to 20 days), and should be warmed for 18 to 24 hours to achieve a temperature of 35 °C to 38 °C. . After opening the skylight, draining and cooling, after 18 to 24 hours, the temperature of the sputum is reduced to 15 ° C; during the middle of storage (20 days after the sputum to the beginning of the second year of spring and February), mainly to keep warm and warm to prevent the potato species from being chilled. At this time, the temperature of the sputum should be stable at 12 ° C ~ 13 ° C; in the late storage (to the beginning of February) to check the soil in time to eliminate excess carbon dioxide. The sweet potato stored by the above method has a long preservation time, and the sweet potato has a good rate of over 96%. Wireless Camera Kits With 2 Camera

After entering the 21st century, with the development of network technology, there is an increasing demand for video data storage through the network. The monitoring system with DVR as the core has further developed into a NVR system with network functions.
NVR, namely network video recorder, is the storage and forwarding part of the network video monitoring system. Its core function is the storage and forwarding of video streams. Compared with DVR, NVR has a single function. It does not have analog digital conversion and encoding functions and cannot work independently. It usually works with video encoder DVS or network camera IPC to complete video recording, storage and forwarding functions.
