For example, the big data platform for farmland quality protection, through the construction of "1 center, 1 platform, n application" platform construction mode. The construction of the Big Data Center for Cultivated Land Quality Protection will gather the quality data of three cultivated lands: soil, water and fertilizer, and provide data support for monitoring, management, service and application of cultivated land quality protection. Using big data analysis, we can achieve accurate management and scientific decision-making, form a new format of commanding cultivated land, change the protection mode of cultivated land through big data platform, serve the public and manage it.
Top-level water and fertilizer integrated intelligent irrigation system, top-level water and fertilizer integrated automatic control system consists of system cloud platform, soil moisture data acquisition terminal, video monitoring, fertilizer applicator, filtering system, valve controller, solenoid valve, field pipeline, etc. The system can make periodic water and fertilizer plans and implement rotation irrigation according to the monitored soil moisture and the fertilizer demand law of crop varieties. According to the formula and irrigation process parameters set by users, the fertilizer applicator automatically controls the important parameters of the water and fertilizer process, such as irrigation amount, fertilizer absorption amount, fertilizer solution concentration, pH value and so on. , so as to realize the timing and quantitative control of irrigation and fertilization, fully improve the utilization rate of water and fertilizer, save water and fertilizer, improve soil environment and improve crop quality. The system is widely used for planting and irrigation in fields, dry fields, greenhouses and orchards.
