Field irrigation and temperature control integrated system and use method thereof

Abstract

The invention discloses a field irrigation and temperature control integrated system and a use method thereof. The field irrigation and temperature control integrated system comprises an infiltrating irrigation system and a temperature control system, the infiltrating irrigation system comprises a main pipe communicated with an irrigation pump room, the main pipe is connected with a plurality of branch main pipes, the tail ends of the branch main pipes are all connected with circulating pipes, the circulating pipes are connected with a temperature control pump room, a plurality of branch pipes are connected to each branch main pipe at intervals, a plurality of temperature control pipes are connected to the two sides of each branch pipe, the other ends of the temperature control pipes are connected with a temperature control water supply pipe, the tail end of the temperature control water supply pipe is connected with the temperature control pump room, and the temperature control water supply pipe, the temperature control pipes, the branch pipes, the branch main pipes, the circulating pipes and the temperature control pump room form a temperature control system. The system is combined with an infiltrating irrigation system pipeline, so that the soil temperature can be adjusted, and the abnormal change of the soil temperature under extreme weather is relieved; the temperature control system is not limited by time and places, and can better adapt to the requirement of the crop growth cycle for temperature and overcome the influence of extreme weather or climate on the soil temperature.

Description

technical field [0001] The invention relates to a field seepage irrigation system and a use method thereof, in particular to a field irrigation temperature control integrated system and a use method thereof. Background technique [0002] Water, fertilizer, air, and heat are indispensable key factors in the process of crop growth and development. Different crops have different sensitivities to temperature, and different growth stages of the same crop have different temperature requirements. Therefore, timely adjustment of soil temperature can better meet the needs of crop growth; at the same time, in the face of extreme weather or climate change When it is suitable for crop growth, the temperature of soil moisture and other indicators can be changed by adjusting the soil temperature, so that the soil temperature is suitable for crop growth. [0003] The existing crop temperature is mainly adjusted by adjusting the air temperature, generally using a greenhouse or covering the...

AI Technical Summary

Problems solved by technology

When encountering high temperature weather or long-term high temperature climate, the crops in the greenhouse are not suitable for crop growth due to high temperature. At the same time, high temperature will also increase crop transpiration and soil water evaporation, which is not good for water-saving irrigation; When encountering cold weather or a cold climate in the north, the freezing of moisture in the soil is extremely unfavorable to crop growth, and plastic film covering cannot cope with the growth conditions in cold climates. At the same time, plastic film is a disposable plastic product, which is harmful to the soil and the ecological environment. will cause damage

Although the greenhouse can cope with cold weather, it usually has a greater impact on the air temperature in the greenhouse and has a limited impact on the soil temperature; at the same time, in the northeastern permafrost region, external heating equipment is generally required in the greenhouse, and the investment and maintenance costs are high, so it is not suitable for long-term use.
