Common water-saving irrigation methods currently used in China include canal lining, sprinkler irrigation, micro-sprinkler irrigation, seepage irrigation, and drip irrigation. These all involve artificial control of irrigation opportunities and water volume, falling under the category of "passive" irrigation methods. Israeli drip irrigation technology is widely recognized as the most effective water-saving irrigation technology currently available. Since its introduction to China in the late 1970s, it has made significant progress. This article will introduce the advantages of water-saving irrigation: 1. Significant water-saving effect, with water utilization rates reaching 80%. Generally speaking, compared to surface irrigation, 1 cubic meter of water used in sprinkler irrigation can achieve the effect of 2 cubic meters. 2. Significant increase in crop yield, generally reaching 20%-40%.

Water-saving irrigation is an irrigation method that achieves maximum yield or return with the minimum amount of water, maximizing crop yield and output per unit of irrigation water. Water-saving irrigation is scientific irrigation and sustainable development irrigation, encompassing three aspects: engineering measures, agronomic measures, and management measures. Engineering measures include the construction of water ponds, cisterns, reservoirs, and other water source projects; seepage prevention of channels; conversion of open channels to pipeline water conveyance; improvement of canal and pipeline systems with various gates and valves; installation of water measurement devices; and the adoption of advanced irrigation methods such as sprinkler and drip irrigation, improving traditional surface irrigation methods such as furrow irrigation, ridge irrigation, and flood irrigation.

The integrated water and fertilizer spray irrigation technology can irrigate appropriately according to the crop's water needs and soil conditions, improving the microclimate in the field and ensuring that the water, fertilizer, air, and heat in the soil are always in optimal condition. Secondly, spray irrigation can wash away dust and pests from the surface of leaves, reducing tea tree diseases and insect pests, and enhancing photosynthesis. In the dry season, under suitable irrigation conditions, tea yield can be improved, and tea quality significantly enhanced. Micro-spray irrigation is a new type of water-saving irrigation method developed on the basis of drip irrigation and spray irrigation. It has the advantages of saving water, increasing crop yields, energy saving, easy automation control, and adaptability to terrain.

The water-fertilizer integrated system utilizes the principle of crop nutrient absorption, combining irrigation and fertilization processes. Fertilizer is dissolved in water and delivered through a pressure irrigation system, achieving simultaneous water and fertilizer management to improve water and fertilizer utilization efficiency. In recent years, with the continuous development of agricultural technology, the water-fertilizer integrated system has gradually become standard equipment in modern agriculture due to its advantages in water and fertilizer saving and precise control. However, in large-scale greenhouses, once the water-fertilizer integrated system malfunctions, it will cause unpredictable damage to agricultural production. Equipment inevitably faces obsolescence and aging. Late winter and early spring is the start of a new round of agricultural production.

Since the introduction of water and fertilizer integrated technology, China's water and fertilizer integrated technology system and mechanism have become increasingly mature and perfect. At present, most vineyards use irrigation and fertilization combined water and fertilizer integrated technology, which has achieved remarkable results. 1. Improving water and fertilizer utilization efficiency Traditional fertilization technology lacks scientific and reasonable basis, excessive fertilization, on the one hand, leads to reduced yield and quality, on the other hand, leads to soil degradation and nutrient loss, making the environmental conditions unbalanced. Water and fertilizer integration uses the method of simultaneous fertilization and irrigation, using a drip irrigation system to combine water and fertilizer, fertilizing during irrigation, and maximizing efficiency.

Drip irrigation tape is the core product of the drip irrigation system and plays a decisive role in the operation effect of the drip irrigation system. Low-quality drip irrigation tape is prone to aging and cracking, flow channel blockage, large flow deviation, and uneven irrigation and fertilization during use. Employees' independent purchases may lead to irreparable losses in agricultural production and water and fertilizer management due to their inability to distinguish between the quality of drip irrigation tapes. How to judge the quality of drip irrigation tape? Below, Dafengshou drip irrigation tape manufacturer teaches you how to choose high-quality drip irrigation tape. First, check the appearance in three aspects: First, check the color, which is generally black and uniform; second, look at the surface, which should be smooth, flat, without bubbles, hanging material lines, hardened blocks, impurities, etc.; third,
