| Abstract: |
| The Huang\|Huai\|Hai plain is an important region for grain production in China. The average multiple cropping index in Huang\|Huai\|Hai region is 150%. The two\|year triple cropping system includes two crops a year of wheat and maize plus spring sowing crops, which is the main planting system in this region. Limited by water resources, the multiple cropping index in some areas has a downward trend, which has seriously affected regional food security. Developing water\|saving and efficient farming system is a major scientific and technological problem to solve regional food security and ecological security. This report focuses on two aspects, one is the water\|saving and efficient farming system for wheat and maize as well as spring sowing crops. The former focuses on the technical innovation and integration of biological and agronomic water conservation, such as straw return and efficient farming, high sprinkler irrigation, water and fertilizer integration, fertilizer and water coupling, and soil moisture measurement and supplementary irrigation, etc. The latter focuses on the development of multi\|functional biodegradable mulching film and the technical system of covering crops such as peanut and potato and saving water and increasing production. On this basis, this study puts forward the development direction and technical needs of the farming system in the water shortage irrigation area of the Huang\|Huai\|Hai Plain including adopting the combination of subsoiling and straw returning, subsoiling and high sprinkling irrigation, waste returning, reasonable irrigation and nitrogen fertilizer application, and plastic film covering technology in order to provide strategic and technical support for food security and ecological security in the water shortage irrigation area of the Huang\|Huai\|Hai Plain. |
