1. Fat burning seedlings. Because the base fertilizer is not decomposed and the seed fertilizer (fertilizer, trace fertilizer) is applied excessively, the seedlings and seeds are exposed to these fertilizers, and are easily burned, resulting in yellowing of the leaves or tips. Watering can be used to remedy, poured once a day, even for a few days. 2. Medicine injury seedlings. If the concentration of the seed dressing pesticide is too large, the root tip will be injured and the yellow seedling will be caused. If the problem is not serious, there is no need to control. After the secondary root grows, the wheat seedling naturally turns from yellow to green. But when the problem is serious, it should be remedied by watering and loosen after watering. 3. Deep sowing seedlings. Due to the deep sowing, the stems in the ground are too long, the seed nutrient consumed is too much, the seedling leaves are slender, the roots are stunted, and the wheat seedlings are thin. For this kind of wheat seedlings, some cover soil can be cut off to make the thickness of the tiller section shallower; combined with cultivator, improve soil ventilation, promote lateral root development, and make the seedlings turn strong. 4. Rough seedlings. If the soil preparation is not fine, the large soil in the soil is too large, the soil is too loose, and the roots are not tied well. The wheat seedling grows slowly, shrinks the heart, yellow leaves and weak seedlings. For this kind of wheat seedlings, crush and crush the soil as soon as possible and water it. 5. Over dense seedlings. For wheat fields sown earlier and sown in larger quantities, wheat seedlings often grow too profusely, and wheat seedlings develop yellow due to poor nutrition and poor development. On the one hand, soil pressure can be used to make growth slower and grow thicker; on the other hand, it is necessary to plough the roots deep to control the increase of tillers and the excessive growth of small tillers, which will help strong seedlings grow. 6. Missing gas seedlings. If the soil is too viscous, poor texture, too much water, poor soil permeability, will seriously affect the growth and development of roots, the primary root was brown, weak tillering force, thin seedlings, yellow or pale brown tips. For such wheat fields, deep trench drainage, loose tillage, ventilation, increased ground temperature, and root development are required. 7. Dry seedlings. Due to dry weather or lack of soil moisture, wheat seedlings have difficulties in absorbing water, resulting in slow growth, grayish-green leaves, long leaves, and yellow base leaves, less secondary roots, and difficulties in childbirth. It should be timely watered and fertilized to promote the normal growth of young wheat seedlings and seedlings. 8. Salt seedlings. The plants are thin and short, with few tillers, narrow leaves, many yellow leaves at the base, yellow-green leaves, and purple-red leaves. Soils should be ploughed in time to reduce evaporation on the ground to prevent back salinization. Where conditions permit, irrigation salt washing or salt draining can be used to reduce soil salinity. 9. Diseases and Insects. Yellow seedlings and weak seedlings are formed due to hazards of underground pests (flea, earthworms, etc.) and root rot. It is necessary to take preventive measures in time to ensure strong seedlings.

Installation and use should be relatively simple, mainly reflected in two aspects: one is that the installation and debugging of the camera itself should be relatively simple, and the other is that the operation of the client should be relatively easy to get started. Regarding the installation location and height, we have chosen a height of about 3 meters as a suitable installation location. This not only ensures good visibility, but also prevents the camera from being easily damaged by people PTZ Solar Camera,Solar CCTV PTZ Camera,Home Security Outdoor Camera,Security Outdoor Solar Camera,Solar Camera Shenzhen Fuvision Electronics Co., Ltd. , https://www.outdoorsolarcamera.com

Bad.
3. To support multiple recording storage modes, not only local storage but also cloud storage should be supported.
Four. In the process of purchasing cameras, it is best not to be greedy for cheap prices and not simply pursue cheap prices. It is necessary to comprehensively consider factors such as the stability and clarity of the camera head. Whether the operation of the camera head is stable is determined by the 40 modules in the middle
The clarity is determined by the image sensor.
5. Because the 40 surveillance camera belongs to an all-in-one machine, the product structure is relatively simple, and there are no complex circuits, so it is very stable during use
