Description

technical field

[0001] The invention belongs to the field of agricultural technology, and relates to a green drip irrigation and water-saving cultivation method for winter wheat / summer corn rotation system, especially to provide a low-cost, low-pollution, high-efficiency and high-efficiency cultivation for winter wheat / summer corn rotation areas in the North China Plain method. Background technique

[0002] Winter wheat / summer maize double-cropping rotation system is the main grain planting method in the Huanghuaihai region of North China. However, due to the shortage of water resources in North China and the serious situation of groundwater overexploitation, agriculture is the main groundwater user in shallow groundwater overexploitation areas. The lack of water during the crop growth period leads to a decline in yield, which seriously affects my country's food security. With the increase of population, the reduction of arable land, the acceleration of urbanization, factors...
