Planting forests on bare mountains is a great contribution of infiltration irrigation technology under trees invented by retired soldier Hubert Wu. Many saplings of Pinus tabulaeformis with withered and dying branches were saved by his infiltration irrigation technology and brought back to life.
"In the past, floods flooded, and 1 mu of land used dozens of cubic meters of water. Using this infiltration irrigation technology only needs 1 cubic meter of water, and saves labor and cost. " Zhao Guichun, a villager in Wowojing Village, Lanzhou New District, said.
Under-tree infiltration irrigation equipment in Hubert Wu is divided into pipelines and devices. Pipeline water supply, equipment leakage. There is a water supply at the root of the tree. When the tree is short of water, water will slowly penetrate into the roots, effectively maintaining the survival of the tree. When it rains, the water will automatically fill the reservoir, instead of directly infiltrating into the ground for reuse during drought. Hubert Wu introduced: "Gansu is located in the northwest inland, and there is little precipitation in many places, so it can only develop dry land agriculture. New technologies can allow farmers to use less water, save labor and grow alive. "
In order to let more people know about this new technology, Hubert Wu applied for a company to make a tour to Minqin, Jingtai, Jingyuan and other rural areas in Gansu, which are dry and short of water, to introduce root infiltration irrigation technology. In Jingtai county, new technology helped local farmers plant more than 200 mu of trees, and the survival rate reached over 95%. On the edge of Tengger Desert in Minqin County, farmers planted thousands of Salix psammophila with this technology.
Less clogging of drip holes is another significant advantage of this technology, which further saves the cost. A few years ago, the 3,000-mu Lycium barbarum forest planted by Ningxia Zhongning Lycium barbarum Industry Group was closed after one year of drip irrigation technology. Hubert Wu was found in Zhongning County, and Chinese wolfberry 100 mu was planted in the export base of organic Chinese wolfberry by infiltration irrigation technology. The experimental results are very good.
Yang Hongwei, full-time secretary-general of Jingning Chamber of Commerce in Lanzhou and general manager of Gansu Long Fu Trading Co., Ltd., has been paying attention to this technology for nearly three years. "I went to see his planting site from 20 15. I went there a few days ago, and there was really no traffic jam. Hubert Wu's technology looks unremarkable, but it can really solve the problem. "
20 13 the Science and Technology Department of Ningxia's report on infiltration irrigation shows that root infiltration irrigation water-saving device is a kind of irrigation device different from various water-saving technologies, which saves 30% water than drip irrigation, but the material cost is 70% to 80% lower than drip irrigation technology, which is more practical and can realize intelligent remote control.
The barren slope in Lintao County, Gansu Province is alkaline and short of water, which makes agricultural development more difficult and the profit lower. This phenomenon is common in northwest China. From April, 2065438 to April, 2007, Jingping Industrial Park in Lintao County adopted root infiltration irrigation technology to plant more than a dozen cash crops such as apricot, jujube and walnut trees in the wasteland, with a survival rate of 90%. Alfalfa and lawn are also interplanted under the economic forest, with more than 2 tons of green feed per mu. Chickens and sheep were raised with green feed, and then returned to the fields, realizing the ecological organic cycle.
The new agricultural technology has gradually opened up a new world. Jingning county is a big agricultural county and a water-deficient county, and it is very concerned about agricultural water-saving technology. With the support of the local government and cooperatives, the county and Hubert Wu team reached a preliminary cooperation intention on the water-saving pilot project of the apple science and technology demonstration site in the north of the county.
"Jingning has 1 more than 10,000 mu of apple trees, and the annual comprehensive cost of flooding 1 mu is about 1.6 million yuan. If water and fertilizer infiltration irrigation technology is adopted, 1 mu of land can at least save 300 yuan, and the cost of remote control will be cheaper. It is estimated that at least 3 billion yuan will be saved for local agriculture during the service life of 10- 15. " Hubert Wu said.
"This technology has also solved a real problem: the rural labor force is decreasing and aging, and the problem of labor shortage has emerged. This technology is a good combination of water and fertilizer integration, precise fertilization and precise watering, plus remote automatic control, which saves water and manpower. " Yang Hongwei said.
The times are developing and science is progressing. Nowadays, it is no longer the mode of relying on the sky to harvest. As long as we are thoughtful and willing to work hard, we will still develop agriculture into a new world.
