Technical Field

The invention relates to the technical field of agricultural equipment, in particular to a combined type rice stubble wheat irrigation and drainage integrated outlet device.

Background

The seeding area of rice stubble wheat in China is about 480 kilohm²Mainly distributed in Yangtze river basin and Huaihe river basin. Because the photo-thermal resources in the planting area are rich, the rainfall is more, the limitation of the water resources to the growth period of the wheat is small, and the method is an area with the largest yield-increasing potential of the wheat in China. However, the rainfall is too large, the underground water level is high, the rainfall duration is long, the soil of a wheat root system dense layer is in a saturated state for a long time, the oxidation-reduction potential is high, and the rainfall exceeds the tolerance duration of wheat, so that physiological obstacles such as difficulty in water absorption and fertilizer absorption of the root system and the like are caused, and the yield and the quality are reduced. The relative humidity of air among plants is too high due to long-term waterlogging disasters, and under the condition of proper temperature, pathological obstacles such as sheath blight, gibberellic disease and the like are caused, so that the yield and the quality are reduced, and waterlogging damage is caused. In addition, seasonal drought, especially spring drought, occurs in large area and long time, which seriously restricts the production of wheat with rice stubble.

The drainage system for rice stubble wheat planting usually adopts a field drainage mode of 'carriage ditch + waist ditch + circumferential ditch + agricultural ditch', water and soil loss is caused due to the lack of an effective outlet matching device, nitrogen and phosphorus attached to soil are lost, the sustainable production of farmlands is seriously influenced, and meanwhile, the threat to the pollution of downstream water is caused.
