Orchard fertilization new technology should be vigorously promoted

At present, the fertilization structure in the fruit industry remains highly inefficient. Many farmers still rely on unscientific methods, such as over-fertilizing, under-fertilizing, or applying nutrients in an imbalanced way. These practices not only lead to excessive waste of resources but also damage soil health over time. In some cases, improper application can even cause fertilizer burn, which negatively affects the growth and yield of fruit trees, ultimately reducing fruit quality and market value. As consumer demand for safe, high-quality, and environmentally friendly fruits continues to rise both domestically and internationally, it is essential to raise awareness and promote scientific fertilization techniques in orchards. First, it is crucial to actively promote soil testing and balanced fertilization. This approach involves analyzing the soil’s nutrient content and then formulating a precise fertilizer plan based on the specific needs of the crops. By combining organic and mineral fertilizers, farmers can apply the right amount and ratio of nutrients, ensuring optimal growth conditions for fruit trees while minimizing environmental impact. Second, expanding the use of organic fertilizers is key to sustainable orchard management. High-quality fruit production requires more organic inputs and less reliance on synthetic fertilizers, especially in the production of pollution-free fruits. Organic materials such as compost, manure, biogas slurry, green manure, crop straw, and other biological residues are rich in nutrients and help improve soil structure. Local governments should encourage the use of local resources to produce organic fertilizers, reducing dependency on livestock-based manures. For example, straw, leaves, and distiller’s grains can be effectively utilized. Farmers are encouraged to apply at least 1,500 kg of organic fertilizer per acre to maintain soil fertility and meet the growing demand for organic nutrients. Third, promoting specialized compound fertilizers for fruit trees is another effective strategy. These fertilizers are formulated to meet the specific nutritional needs of fruit crops, containing nitrogen, phosphorus, potassium, and micronutrients in balanced proportions. Compared to traditional fertilizers, they offer better efficiency, reduce waste, and enhance productivity by up to 15%. They are easy to use, provide long-lasting effects, and help increase the overall economic return for farmers. Fourth, the adoption of controlled-release fertilizers is gaining momentum. These smart fertilizers release nutrients gradually according to the plant's requirements, matching the natural uptake cycle. This reduces the need for frequent applications, saves labor, and improves nutrient utilization. They also contribute to better fruit quality, higher yields, and a healthier soil environment, making them a sustainable choice for modern agriculture. Fifth, attention must be given to the proper use of potash fertilizer. Potassium deficiency can impair flower bud formation, reduce cold resistance, and affect fruit coloration and quality. Many orchards suffer from potassium depletion due to insufficient organic input. To address this, increasing organic matter and returning crop straw to the soil is essential. For orchards showing clear symptoms of potassium deficiency, foliar or root application of potassium fertilizers during June to August—when root activity is high—can significantly improve tree health and fruit quality. Lastly, the importance of trace elements such as calcium, boron, zinc, and magnesium cannot be overlooked. Though required in small amounts, these micronutrients play a vital role in fruit development and quality. For instance, boron and zinc improve fruit coloring, while calcium enhances fruit firmness. Proper application of these elements ensures that fruit trees remain healthy and productive, leading to superior yields and marketable products.
