The invention discloses a device for accelerating farmland water-air-heat circulation by using hidden pipes in saline irrigation areas, which includes water collecting pipes and a group of ventilation devices; the ventilation device includes V-shaped hidden pipes, and the two ends of the hidden pipes are closed by the hidden pipe plugs The dark pipe is provided with several ventilation holes in sequence along its axial direction, the middle part of the dark pipe is connected with a ventilation pipe, and the top of the ventilation pipe is provided with a non-powered fan; the dark pipe is connected through a water collection pipe. Realized the use of hidden pipes to quickly control the groundwater level in saline irrigation areas and automatically accelerate the water-air-heat cycle of farmland, automatically increase the ground temperature and automatically improve the ventilation and air permeability of the crop canopy, energy saving and environmental protection, simple process, convenient maintenance, and low cost It is cheap and effectively improves the growth environment of crops in saline irrigation areas.
Description
technical field [0001] The invention belongs to the technical field of farmland water-gas heat cycle and microclimate improvement, and relates to a device for accelerating farmland water-gas heat cycle by using a hidden pipe in a saline irrigation area. Background technique [0002] Water, air, and heat are not only essential nutrients for crop growth, but also key factors that directly affect the efficient use of water and fertilizer in farmland. Water, air, and heat directly affect plants' absorption of soil moisture and nutrients, and the heat and oxygen required to ensure seed germination, root development, and flowering and fruiting. There are pores of different sizes and shapes between soil particles, and water and air mainly exist in the soil pores. Soil pores are also important channels for soil water, air, heat exchange and circulation. The exchange and circulation of water, air and heat directly affect the soil fertility and the ability to supply the oxygen, wate...
