Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of greenhouse planting, and in particular relates to a fertilizing device for a greenhouse. BACKGROUND

[0002] Greenhouse planting breaks through the season and region limitations of traditional agriculture by precisely regulating light, temperature, humidity and soil environment, realizes stable production throughout the year, and significantly improves crop yield and quality. Its closed environment effectively resists extreme weather, pest invasion, reduces pesticide dependence; at the same time, it can recycle water and fertilizer resources, reduce soil erosion and pollution, and provide ideal growth conditions for high-value vegetables, fruits and flowers. In the background of limited arable land and intensifying climate change, greenhouse technology guarantees food security through intensive production, promotes the transformation of agriculture to high efficiency, intelligence and sustainability, and becomes the core pillar of modern precision agriculture.

[0003] The importance of designing an automatic fertilizing device in greenhouse planting lies in that it can monitor soil nutrients and crop demand in real time through intelligent sensing and automation technology, precisely regulate water and fertilizer ratio and application timing, and break through the limitations of traditional extensive fertilization. It can dynamically adapt to changes in temperature and humidity in the greenhouse, avoid high-temperature volatilization or low-temperature absorption obstacles, and ensure balanced fertilizer supply throughout the crop cycle. At the same time, its automatic operation significantly reduces labor costs, avoids human error, and realizes water and fertilizer saving with an integrated water and fertilizer system, helping high-yield and high-quality planting. This innovation upgrades traditional agriculture to a data-driven precision model.

[0004] Chinese patent application with publication number CN117158170A discloses an agricultural greenhouse fertilizing device. This device controls the amount of fertilizer by changing the position of the fertilizer block, improves the accuracy of fertilization to avoid fertilizer waste, and can move within the greenhouse to change the diameter of the supporting wheel according to different plant spacing. However, this device cannot automatically fill the fertilizer, and cannot automatically bury the soil during the fertilization process, which requires additional manual soil burying, reduces the fertilization efficiency, and cannot effectively clean the fertilizer storage location, increasing the risk of cross contamination.
