Description

A water-saving irrigation system and method based on data analysis

technical field

The invention relates to the field of energy-saving irrigation, in particular to a water-saving irrigation system and method based on data analysis.

Background technique

Water-saving irrigation is an irrigation measure that maximizes crop yield and output value per unit of irrigation water to obtain the maximum yield or benefit with the minimum amount of water. Water-saving irrigation can achieve better production and economic benefits with less irrigation water. It is required to take the most effective technical measures to make the limited irrigation water create the best production and economic benefits. The current main application field of water-saving irrigation is the greenhouse. The greenhouse can effectively adjust the temperature of the plant production environment, and realize the establishment of the microenvironment through temperature adjustment, and effectively realize the efficient use of water resources. However, at present, there are still many defects in the implementation of water-saving irrigation in the greenhouse. Expressed as:

The first is the problem of evaporation consumption. Crops and green vegetation need water to participate in photosynthesis in the whole process from seed germination to growth. However, more than 99% of the water consumed by plants is used for leaf transpiration and soil evaporation between plants to regulate crop body temperature, improve microclimate and deliver nutrients to plants. This part of the evaporated water cannot be well recycled, and this waste is even more serious when the greenhouse planting and irrigation operations are in operation, and most of the water vapor is taken away through ventilation operations, resulting in the dissipation of water resources;

Secondly, the traditional technology to avoid water waste in irrigation is mainly channel anti-seepage technology, and channel seepage is the main aspect of farmland irrigation water loss. After the anti-seepage technology of the canal is adopted, the water utilization coefficient of the canal system can generally be increased to 0.6-0.85, which is 50%-70% higher than that of the original soil canal. However, the traditional canal irrigation technology is not widely used, especially in greenhouse or greenhouse planting, it is difficult to implement, and affected by the terrain structure, it is extremely difficult to promote this technology in greenhouse planting operations.

Again, affected by the temperature difference and weather factors, the evaporated water vapor will quickly dissipate, and a large part of the water in the irrigation operation in the greenhouse is condensed on the top or side wall of the greenhouse with the evaporation of the plants. As the operation of the ventilation operation gradually dissipates, the treatment of this part of the water is greatly wasted. In some places where water resources are scarce, this consumption has caused a great waste of resources.

It can be seen from the above that when planting in a greenhouse, a standardized water-saving irrigation system is urgently needed. Through the effective collection and feedback of various data in the greenhouse, the water-saving irrigation operation can be maximized based on the effective feedback of various data in the greenhouse. , to ensure the effective use of water resources and maximize the utilization of water resources.
