In today's increasingly scarce water situation, agriculture, as a large water user, water-saving irrigation has become a necessary measure. Traditional irrigation methods are often inefficient, the utilization rate of water is not high, and the phenomenon of waste is serious. The new water-saving irrigation technology - "one cloth and one film" is gradually becoming a new favorite in the field of agricultural water-saving irrigation.
"One cloth and one film" is an irrigation method that combines plastic film mulching with drip irrigation technology. Efficient and water-saving irrigation is achieved by laying drip irrigation pipes under the mulch film to deliver water directly to the roots of the crops. This new irrigation technology not only improves the efficiency of water resources, but also has many advantages.
First of all, "one cloth and one film" can increase soil temperature and reduce soil moisture evaporation. Plastic film can effectively inhibit the evaporation of water in the soil, reduce the fluctuation of soil temperature, and keep the soil at a suitable temperature, which is conducive to the growth of crops. At the same time, the mulch film can also effectively inhibit the growth of weeds and reduce the workload of weeding.
Secondly, "one cloth and one membrane" can improve the utilization rate of irrigation water. Drip irrigation technology delivers water directly to the roots of crops, avoiding water waste and evaporation. At the same time, the drip irrigation pipe can also accurately control the supply of water and fertilizer according to the needs of crop growth, so that crops can get a suitable supply of water and fertilizer.
In addition, "one cloth and one film" also has the advantages of easy operation and manpower saving. The traditional irrigation method requires a large amount of manual irrigation, while the irrigation method of "one cloth and one membrane" can be controlled by the automatic control system, which greatly reduces the manual input. At the same time, the laying and production of "one cloth and one film" are more convenient, reducing the workload of farmers.
In practical application, the "one cloth and one film" irrigation technology has also achieved remarkable results. In some areas, the application of "one cloth and one film" has shortened the growth cycle of crops by more than 20%, increased yields by more than 30%, and water use efficiency has reached more than 90%. This fully proves the importance and advantages of "one cloth and one film" in agricultural water-saving irrigation.
Of course, there are some problems and challenges with the "one cloth and one film" irrigation technology. For example, the problem of mulch film and treatment, the blockage of drip irrigation pipes, etc. Therefore, when promoting and applying the "one cloth and one membrane" irrigation technology, it is necessary to fully consider these problems and take effective measures to solve them.
To sum up, as a new type of water-saving irrigation technology, "one cloth and one membrane" has many advantages and advantages. It not only improves the use of water resources, but also promotes the growth of crops and increases yields. Therefore, "one cloth and one film" has broad application prospects and development space. In the future, we need to further strengthen its research, popularization and application, constantly improve and improve its technical level, and make greater contributions to the development of agriculture and water-saving irrigation.
