The application of organic fertilizer as a base fertilizer on the basis of fertilizer and applied fertilizer, is an important part of improving corn production. In particular, if there is a small amount of base fertilizer, or if the base fertilizer is used at the end, fertilizer must be applied in a timely manner. A variety of nitrogen fertilizers can be applied as top dressings. The time, amount, and number of top dressings should be determined based on soil fat thinning, how much basal fertilizer and seed fertilizer are used, and climatic conditions.
(1) Lightly apply Miaofei to ensure that the seedlings are fully grown, seedlings are evenly distributed, and seedlings are strong: In the 4-5 leaf stage of the seedlings, 20 kg of calcium ammonium nitrate and 10 kg of calcium sulphate per acre are used in combination with the first time to promote seedling growth. Be careful not to let the fertilizer fall on the leaves during fertilization to prevent sprouting.
(2) Heavy panicle fertilizer: Corn enters the big bell-mouth period (10-12 leaves) combined with the second cultivator soil, 25-30 kg urea per gram, 30-40 kg kg of calcium, promote its strong stalk, big spike .
(3) Steady application of granular fertilizer: After corn heading, although the size of the ear and the number of grain rows have been determined, the absorption of nutrients has gradually begun to slow down. However, if the supply of fertilizer is insufficient, premature aging of the plant will be caused and the grain filling will be affected. Poor grouting. Appropriate replenishment of granular fertilizer can prevent premature senescence and prolong the active period of plant roots and leaves, manifesting as live stalk maturation, increasing grain weight, and thus obtaining high yield.

As technology grows, Vehicle Surveillance System is getting maturer and maturer. Vehicle Surveillance System is made of Vehicle Surveillance Cameras, MDVR, Web connecting, and monitor manage system. Now let's get known of the Car Surveillance Camera.
Vehicle Camera has different types according to their installation locations and aims. Generally speaking, a truck/ police car/ tanker truck/ bus should be equipped with several camers not only one, to realize the no blind spot monitoring and keep safe.
Let's take a closer look at car CCTV cameras:
â— Front-view camera: installed in the front of the car, it acts as a driving recorder;
â— Driver's camera (ADAD/DMS): Installed at the driver's position, it regulates the driver's behavior according to automatic AI analysis. If the driver is distracted, smokes or continues to drive in a fatigued state, the system will automatically alert the driver of his/her bad behavior and record the event;
â— In-vehicle camera: Installed in the car to achieve no blind spot monitoring in the car;
â— Rear view camera: installed at the rear of the car to monitor the road conditions behind the car.
Therefore, the best way is to customize a suitable in-vehicle monitoring system according to the specific application. Sanan Technology has been focusing on the vehicle CCTV camera system for more than 10 years. All cameras have the characteristics of shockproof and waterproof, and full HD night vision effect. They are not afraid of using in any environment. We are good at vehicle monitoring system solutions. "Safety anytime, anywhere, experts in vehicle monitoring systems" is our slogan and we are working towards it.
We would be very appreciated if we can get be given the chance to cooperate, and then we would grow together.
