In response to the problems of serious waste of water and fertilizer resources, untimely and uneven irrigation, and difficult increase in yield per unit area in corn production, a long-term positioning observation study has been carried out for nearly 20 years around field drip irrigation at the Shiyang River Experimental Station of China Agricultural University. It was found that drip irrigation has four major effects compared to traditional border irrigation, namely "promoting surface warming, accelerating crop growth, reducing photosynthetic noon break, and increasing harvest index". From a new perspective, the mechanism of water-saving and yield-increasing by drip irrigation was revealed, and a five-link drip irrigation water-saving super-high-yield technology model was created, including the use of "medium-late maturity varieties, film mulching and shallow buried drip irrigation methods for planting, reasonable close planting, integrated intelligent control of water, fertilizer and pesticides, and comprehensive prevention and control of pests and diseases". This model was tested and demonstrated in the 1,000-mu intelligent drip irrigation corn base in Wuwei, Gansu. The experts measured the dry weight of the grains to reach 1.29 tons per mu, and the total amount of irrigation water used was 280 cubic meters. The productivity of irrigation water per cubic meter reached 4.6 kilograms per cubic meter, which was 15% higher than the average yield per plant of drip irrigation corn of surrounding planting companies, and nearly 40% higher than the yield per unit area of corn planted by farmers using traditional border irrigation. The yield per mu was nearly 30% higher, and its yield and irrigation water productivity set a regional record. The results were reported by Xinhuanet Client, Science and Technology Daily, Wuwei Daily, etc. Wuwei TV Station made a special report on this technical model and promoted it to the whole city. This model has controllable costs, mature technology, and significant benefits. It has the potential to be widely promoted in the 70 million mu of drip irrigation planting areas across the country, making important contributions to high-yield and high-efficiency agriculture, and leading the development of field drip irrigation technology globally.
