Excessive application of nitrogen fertilizer to summer maize, wild summer maize, and vegetative growth can negatively impact the plant's development. It reduces the formation of carbohydrates needed for protein synthesis, as well as the development of fibers and lignin. This leads to underdeveloped mechanical structures in stems and leaf tips, making the stems soft and prone to lodging. Additionally, it can delay flowering, which affects overall yield and quality.
Overuse of nitrogen also increases the risk of pest infestations. When plants absorb too much nitrogen, their cell protoplasm becomes more fluid, cell walls weaken, and leaves tend to droop. This creates poor air circulation and low light penetration within the crop canopy, increasing humidity levels—conditions that are ideal for the spread of pests and diseases. As a result, the plant's natural resistance to these threats is reduced.
Moreover, excessive nitrogen can interfere with the uptake of essential micronutrients. For example, when nitrogen fertilizers decompose, they produce bicarbonates that can inhibit the absorption of zinc by maize plants. This can lead to nutrient imbalances and further weaken the plant’s health. In some cases, applying nitrogen during the early growth stage of corn seedlings may cause the seedlings to become overly stiff, reducing their ability to grow properly. Similarly, if there is an excess of nitrogen in the soil and heavy rains occur, the starch stored in pollen grains may decrease significantly, leading to poor pollination and a higher number of empty or poorly developed ears.
In addition, over-reliance on nitrogen fertilizers can harm soil structure. These fertilizers do not contain organic matter and therefore do not contribute to soil improvement. Continuous and excessive use of nitrogen can lead to soil compaction over time, altering its pH balance and reducing its long-term fertility. This not only affects the current crop but also degrades the land for future planting.
Veterinary Ultrasound Scanner
As customers have higher and higher requirements for animal reproduction and animal disease diagnosis and treatment, traditional diagnostic methods such as visual inspection, stethoscope listening, thermometer inspection, and percussion and hammering can no longer meet the needs of animal husbandry production and veterinary clinics. Today, B-ultrasound is playing a big role in human medical diagnosis, and in the future, B-ultrasound will also play a role in animal medicine. We should promote the use of veterinary ultrasound scanner step by step according to the actual situation, popularize the knowledge of the use of veterinary ultrasound scanner, take this as an opportunity, and use it as a ladder to improve the level of veterinary practice in our country.
