Ningxia developed a mobile pressurized water booster that is effective against drought and water

The Ningxia Science and Technology Department project, the Ningxia Academy of Agriculture and Forestry Sciences, the "Integration and Demonstration of Integrated Cultivation and Demonstration of High-efficiency Water-Reducing Agriculture Technology" project, has successfully designed two mobile pressurized water supplements, which can directly inject water or instant soluble fertilizer mixture into the project. The water-saving effect of the 10 cm below the surface is significant, and the water consumption is only equivalent to 25% of the traditional artificial irrigation and 8.3% of the traction vehicle irrigation.

According to Wang Feng, deputy director of the Desertification Control Research Institute of Ningxia Academy of Agriculture and Forestry Sciences, the newly developed mobile pressurized water plenum has a cost price of around 300 yuan, which not only has significant water saving effect, but also is light and labor-saving, adapting to soil and terrain. Strong in nature, it can fundamentally solve the contradiction between dry farming and water saving and agricultural machinery rolling farmland, which is very suitable for decentralized operation with family as the unit. Suitable crops are watermelon, potato, sunflower, corn, jujube, etc., in which corn, potato and other water consumption is 1.5-1.8 cubic meters per mu, while traditional artificial hydration water consumption is about 5-6. Cubic meters per mu, traction mechanical hydration requires 12-15 cubic meters / acre, and there are weaknesses of large evaporation and rapid loss.

In 2006, there was no effective rainfall in the pre-wangwang town of Tongxin County, Ningxia. The mobile type pressurized water supplement was used to replenish water for three times during the whole growth period. The total amount of water supplemented in the mu was only 4 cubic meters, and the yield per mu of watermelon reached 2200-2500 kg, which increased the yield by more than 28%. Out of water and drought resistance.
