Organic granular fertilizer is widely applicable to various planting scenarios due to its comprehensive nutrients, long-lasting fertilizer efficiency and convenient application. However, different crops differ in growth cycle, nutrient demand and planting mode. Precise application combined with crop characteristics can maximize fertilizer efficiency and achieve dual benefits of soil improvement and yield increase.
In vegetable planting, organic granular fertilizer is the core choice to ensure the quality of fruits and vegetables. Solanaceous fruits and leafy vegetables have a short growth period and high nutrient demand. Applying 200–250 kg of organic granular fertilizer per mu as base fertilizer, matched with a small amount of quick-acting fertilizer as seedling fertilizer, can not only avoid bland taste caused by excessive chemical fertilizers, but also continuously supply nutrients and reduce the frequency of top dressing. It significantly increases the content of soluble sugar and vitamins in vegetables, enhances the flavor, and reduces the incidence of soil-borne diseases.
For fruit tree cultivation, long-term soil improvement and quality improvement are more valued. For adult fruit trees, apply 1.5–3 kg per plant in circular trenches along the canopy drip line, once as autumn base fertilizer and once as top dressing at germination stage. Long-acting organic matter can continuously improve orchard soil, avoid soil acidification caused by long-term fertilization, and promote deep root growth. Balanced medium and trace elements can reduce flower and fruit drop, improve fruit sugar content and color uniformity, and significantly raise the commercial grade of fruits. It is especially suitable for perennial economic crops such as citrus, apples and grapes.
In field grain crop planting, organic granular fertilizer is compatible with large-scale mechanical operation. For wheat, corn, rice and other crops, mechanical side-depth fertilization can be adopted, with 100–150 kg per mu as base fertilizer. Its slow-release feature can meet the basic nutrient demand of crops throughout the growth period, and only a small amount of nitrogen fertilizer needs to be supplemented in the later stage. Long-term application can gradually increase the organic matter content of cultivated land, solve the problem of soil fertility decline caused by years of continuous cropping, and realize the long-term balance of stable grain yield and soil conservation.
For flowers, garden seedlings and municipal greening scenarios, the clean, dust-free and regular granular features of organic granular fertilizer are particularly prominent. After hole application or broadcasting, it has no peculiar smell and does not stain leaves. With mild and long-lasting fertilizer efficiency, it can promote robust seedling growth, more flowers and longer flowering period, and improve the structure of greening planting soil to avoid later soil compaction and degradation. It is an ideal fertilizer choice for municipal gardens, home gardening and flower bases.
