Common irrational fertilizer
The shallow fertilizer is easy to volatilize, lose or hard to reach the root of the crop, which is not conducive to crop absorption, resulting in low fertilizer utilization. Fertilizers should be applied 16 to 26 cm below the seed or plant side. The compound fertilizer produced by dichloroform fertilizer with ammonium chloride and potassium chloride is called double-chlorine fertilizer, containing about 30% chlorine, easy to burn seedlings and watering in time. Saline-alkali land and chlorine-sensitive crops cannot be treated with chlorine-containing fertilizers. Excessive application of potassium chloride to leaf (stem) vegetables not only causes the vegetables not to be tender and has many fibers, but also makes the vegetables taste bitter, has poor taste, and has low benefits. Urine-based compound fertilizers have high nitrogen content, biuret nitrogen is also slightly higher, and easy to burn seedlings. Pay attention to the depth of watering and fertilization. Improper application may cause fertilizer damage, burning seedlings, wilting of plants and other phenomena. Excessive application of nitrogen fertilizer, the soil has a large amount of ammonia or ammonium ions, on the one hand ammonia volatilization, the formation of alkaline droplets in the air droplets, burning crops, produce spots on the leaves of burnt. Excessive use of certain nutrient elements not only poisons the crop, but also impedes the absorption of other nutrients by the crop and causes detoxification. For example, excessive application of nitrogen can cause calcium deficiency; excessive nitrate-nitrogen can cause loss of molybdenum chlorosis; excessive potassium can reduce the effectiveness of calcium, magnesium, and boron; too much phosphorus can reduce the effectiveness of calcium, zinc, and boron. 10000Hz High Frequency LiDAR Module 10000 Hz is one of our 2021 new solutions products,which can be widely used in drone postioning, car anti-collision, intelligent traffic monitoring etc. with high accuracy.
