Food is the day of people, and agriculture is the original. In recent years, the integrated technology of water and fertilizer has been widely used in the field of agricultural planting. The water and fertilizer integrated machine solution can help producers realize automatic integrated management of water and fertilizer, which is not only applied to agricultural production, but also applied in scientific research and teaching.
The Agricultural Experimental Base of Jilin University is located in the North Fourth Ring Road of Lvyuan Park, Changchun City, and mainly undertakes the practical teaching and scientific research guarantee tasks of agriculture-related and related disciplines. The base covers a total area of 1200,700 acres, including more than 2 acres of agricultural experimental fields, with a total construction area of 2,<> square meters, which is a comprehensive practical teaching and scientific research guarantee base built by the school for many years, focusing on agricultural sciences, taking into account non-agricultural disciplines, collaborative education, integrated education, and cultivating morality and cultivating people.
Okeqi water and fertilizer integrated machine is composed of cloud platform, data collection terminal, fertilizer spreader, filtration system, valve controller, solenoid valve, field pipeline and other parts. According to the monitored soil moisture, nutrients and fertilizer demand of crop types, the water and fertilizer integrated machine can automatically control the irrigation amount, fertilizer absorption, fertilizer concentration, pH and other important parameters of the water and fertilizer process according to the formula and irrigation process parameters set by the user, so as to realize the timing and quantitative control of irrigation and fertilization, fully improve the utilization rate of water and fertilizer, and realize the purpose of saving water and fertilizer, improving the soil environment and improving crop quality.
Integrated water and fertilizer technology is a new agricultural technology that integrates irrigation and fertilization. It is with the help of pressure system (or terrain natural drop), soluble solid or liquid fertilizer, according to the soil nutrient content and the law and characteristics of fertilizer demand of crop types, mixed into fertilizer liquid and irrigation water, through the controllable pipeline system water supply, fertilizer, so that after the integration of water and fertilizer, through the pipeline, spray gun or nozzle to form sprinkler irrigation, uniform, timed, quantitative, spray in the crop development and growth area, so that the soil in the main development and growth area always maintain loose and suitable water content, and at the same time according to the fertilizer demand characteristics of different crops, soil environment, Nutrient content and fertilizer demand regularity, the demand design of different growth periods, the water and nutrients are regularly quantified, and directly provided to crops in proportion. The advantages of this technology are the fast fertilization efficiency of irrigation and fertilization, and the improved nutrient utilization. It can avoid the problems of high volatile loss, slow dissolution and slow fertilizer efficiency caused by fertilizer application in the dry topsoil layer. It not only saves nitrogen fertilizer, but also benefits environmental protection.

The introduction of Okeqi water and fertilizer integrated machine in the agricultural experimental base of Jilin University aims to promote fertilizer with water and transfer water with fertilizer through comprehensive regulation and integrated management, realize the coupling of water and fertilizer, make water and fertilizer coordinate and promote each other, reduce farmland diseases, comprehensively improve the water and fertilizer utilization efficiency of experimental fields, save labor and time, and ensure the smooth development of experimental teaching and scientific research. Its significance is not only water-saving, fertilizer-saving, environmental protection and efficiency, but more importantly, it has played a leading and promoting role in transforming agricultural development mode and promoting agricultural modernization.
