Scientific irrigation is an irrigation method that professional irrigation companies have been promoting, including modern irrigation methods such as drip irrigation, micro-sprinkler, seepage irrigation, and sprinkler irrigation. It is necessary to make a reasonable design according to the water demand characteristics, growth stage, climate, and soil conditions of the corresponding plants, and formulate a corresponding irrigation system.
This type of method can achieve local precise irrigation. In addition to supplementing soil moisture to meet plant growth needs, fertilizers and pesticides can also be dissolved in water, combined with modern fertilization devices such as fertilizer injection pumps for fertilization and pesticide application. It can also avoid soil salinization. For soils that have been salinized, irrigation can be used to flush soluble salts in the soil to improve the soil. In addition, scientific irrigation methods can also play a role in preventing fruit trees and vegetables from frost, preventing dry and hot wind hazards, and preventing soil wind erosion.
Advantages of water saving irrigation
Scientific irrigation can effectively maintain the good state of water, fertilizer, gas, heat and other phases in the soil, and has many advantages such as water saving, labor saving, energy saving, fertilizer saving, increasing production and income, etc. It is gradually being recognized and used by everyone, but due to capital And lack of understanding, there is still a lot of work that needs to be done by colleagues in the industry.
Since modern times, with the rapid increase of population and the increasingly developed economy, the prominent contradiction between water supply and demand has also been reflected in the worldwide irrigation industry. In addition, there are still problems such as further reducing construction and operation costs, improving irrigation efficiency, and preventing irrigated land from salinization and swamping. In Shouguang, Shandong, the hometown of vegetables in China, there has been a serious problem of soil salinization.
On the other hand, many water-saving irrigation projects currently have the serious problem of just building and not working. Many countries have shifted the focus of irrigation development from developing new irrigation areas to rebuilding old irrigation areas and strengthening irrigation management.
On the basis of absorbing the achievements of modern science and technology, irrigation technology will develop in the direction of water saving and energy saving, optimal scheduling, modern management and monitoring and forecasting. In parts of Northwest, North and Northeast China, where water resources are seriously lacking, it has become a top priority to implement water-saving irrigation and establish water-saving agriculture. In the increasingly prosperous modern facility agriculture, horticulture and garden construction in East China, South China and other regions, it is also necessary to develop scientific irrigation methods.
