2. Excessive application of chlorine fertilizer to leaf (stem) vegetables. The compound fertilizer produced by ammonium chloride and potassium chloride is called double-chlorine fertilizer, and contains about 30% chlorine. It is easy to burn seedlings and should be watered in time. Chlorine-free fertilizers cannot be applied to saline-alkali and chlorine-sensitive crops. Excessive application of potassium chloride to leaves (stem) vegetables not only causes the vegetables to be less tender and more fibrous, but also makes the vegetables taste bitter, with poor mouthfeel and low benefits. The urea-based compound fertilizer has high nitrogen content, and the biuret has a slightly high nitrogen content. It is easy to burn the seedlings, and attention should be paid to watering and fertilization depth.
3. Fertilization method. Due to improper application methods, it may cause fat damage, burning seedlings, plant wilting and so on. For example, excessive application of chemical fertilizers or insufficient soil moisture after fertilization may cause the soil solution concentration to be too high, and the roots of the crops may be difficult to absorb water, causing the plants to wilting or even die. In addition, when there is too much ammonium in the soil, the plant will absorb too much ammonia and cause ammonia poisoning.
4. Excessive use of certain nutrients. In this way, not only will the crop be poisoned, but it will also hinder the absorption of nutrients by the crop and cause deficiency. For example, excessive nitrogen application can cause calcium deficiency; excessive nitrate nitrogen can cause chlorosis in the absence of molybdenum; excessive potassium can reduce the effectiveness of calcium, magnesium, and boron; excessive phosphorus can reduce the effectiveness of calcium, zinc, and boron.
5. Fresh human excrement is directly applied to vegetables. In the process of decay, the unfertilized livestock and poultry manure will produce a large amount of harmful gases such as hydrogen sulfide, which will easily cause the vegetable seeds to suffer from hypoxia and suffocation; and generate a large amount of heat, which may cause vegetable seeds to burn or root rot, which is not conducive to vegetable seeds.

A & M Manufacturing Company Ltd boasts extensive capabilities in manufacturing pump components using a variety of processes tailored to meet diverse industry needs. Our expertise encompasses Investment Casting, Sand Casting, Die Casting, and Forging techniques, each offering unique advantages for specific applications.
Investment Casting:
Investment casting, also known as lost-wax casting, enables the production of intricate pump components with high dimensional accuracy and excellent surface finish. This process is ideal for manufacturing complex parts such as impellers and casings, where intricate geometries are required to optimise fluid flow and efficiency. Investment casting offers exceptional design flexibility, allowing for the creation of custom components tailored to specific pump requirements.
Sand Casting:
Sand casting is a versatile and cost-effective method for producing pump components with complex shapes and sizes. It is particularly well-suited for manufacturing large and heavy-duty components such as housings and wear rings. Sand casting offers excellent material versatility, allowing for the use of a wide range of metals and alloys to meet diverse application requirements. Additionally, sand casting is highly adaptable to low to medium volume production runs, making it a preferred choice for various pump applications.
Die Casting:
Die casting is a high-speed, high-volume manufacturing process suitable for producing pump components with tight tolerances and intricate details. This process is commonly used for manufacturing components such as valve bodies and housings, where precision and repeatability are essential. Die casting offers excellent dimensional accuracy and surface finish, resulting in components with exceptional performance and aesthetics. Additionally, die casting enables the production of lightweight yet durable components, making it ideal for applications requiring strength and efficiency.
Forging:
Forging is a process that involves shaping metal using compressive forces to create strong and durable pump components. Forged components exhibit excellent mechanical properties, including high strength, toughness, and fatigue resistance, making them ideal for critical applications such as shafts and bearings. The forging process ensures optimal grain structure and material integrity, resulting in components with superior performance and longevity. Additionally, forging allows for precise control over material properties, enabling the production of components tailored to specific performance requirements.
At A & M Manufacturing Company Ltd, we leverage our expertise in these advanced manufacturing processes to deliver pump components that meet the highest quality standards and exceed customer expectations. Whether it's investment casting, sand casting, die casting, or forging, we have the capabilities and expertise to manufacture pump components for a wide range of applications, ensuring reliability, efficiency, and durability in every product.
