Traditional agriculture often relies on manual fertilization and extensive flooding irrigation, which not only leads to severe waste of water and fertilizer but also tends to cause soil salinization and uneven nutrient distribution. As a core equipment in smart agriculture, the integrated water and fertilizer machine integrates irrigation and fertilization control, playing an irreplaceable role in the transformation of modern agriculture towards large-scale, green, and intelligent operations.
Firstly, it significantly saves water and fertilizer resources and enhances resource utilization efficiency. The equipment can precisely match the fertilizer concentration and deliver fertilizer and water quantitatively according to crop needs. The fertilizer is directly delivered to the crop roots, avoiding the loss and infiltration of fertilizer with large amounts of water. The fertilizer utilization rate can be increased by more than 40%. At the same time, drip irrigation and micro-sprinkling modes are used to supply water according to demand, saving about 50% of water compared to traditional flood irrigation. This can effectively alleviate agricultural water pressure in arid and water-scarce areas and meets the requirements of water-saving agricultural development.
Secondly, it aids in enhancing the quality and increasing the yield of crops through standardized planting management. The integrated machine can automatically adjust the ratio of nitrogen, phosphorus, potassium, and trace elements according to different growth stages such as the seedling stage, flowering stage, and fruit expansion stage, ensuring a balanced and stable nutrient supply. This effectively reduces issues such as nutrient deficiency diseases, malformed fruits, and flower and fruit drop. After using this technology in greenhouse vegetables, melons, and fruit trees, the fruit quality improves, and the yield steadily increases. This facilitates the creation of standardized agricultural products in fruit and vegetable bases, thereby enhancing the economic value of agricultural products.
Furthermore, it reduces labor costs and achieves streamlined management on a large scale. In the past, contiguous planting bases required multiple people to travel back and forth to the fields for fertilization and watering, which was time-consuming and laborious. The integrated water and fertilizer machine can be programmed to automatically rotate irrigation and fertilization, and when paired with an IoT module, it can also be remotely controlled via a mobile phone, eliminating the need for personnel to be stationed in the fields. This significantly reduces the number of laborers required and is suitable for large-scale planting in family farms, planting cooperatives, and large agricultural parks, promoting the transformation of agriculture from labor-intensive to mechanized management.
Finally, we should improve farmland soil and reduce agricultural non-point source pollution. Extensive fertilization is prone to excessive residual fertilizer, leading to soil compaction and acidification, as well as groundwater pollution. Precise, small-scale, and frequent fertilization can avoid excessive accumulation of fertilizer, gradually improve soil physicochemical properties, reduce ecological problems caused by fertilizer abuse, align with ecological agriculture and fertilizer reduction policies, and promote green and sustainable agricultural development.
In summary, the integrated water and fertilizer machine offers multiple advantages such as water conservation, fertilizer saving, labor saving, yield increase, and soil protection. It serves as a crucial carrier for traditional agriculture to transition towards modern precision farming, and is also an essential equipment for the upgrading and transformation of facility agriculture in the context of rural revitalization.
