Drip irrigation is the most widely used method of water-saving irrigation. Drip irrigation systems are highly efficient in saving water; however, some problems may occur during their application. This article will specifically explain the problems frequently encountered in the practical application of drip irrigation systems. 1. Selection of incorrect emitters Emitters are generally divided into two types: pressure-compensating and non-pressure-compensating. Although pressure-compensating emitters are more expensive, their effect is better. Firstly, pressure-compensating emitters ensure uniform water output from each emitter, leading to uniform fertilization and irrigation. Secondly, some pressure-compensating emitters can flush out debris that blocks the emitters. Also, some pressure-compensating emitters have large flow channels and generally will not be easily blocked.

Irrigation and fertilization are collectively referred to as water and fertilizer management, which is extremely important in agricultural cultivation. With the development of agricultural cultivation professions in recent years, the use of agricultural equipment in cultivation has also increased, and water and fertilizer integrated equipment is one of them. Many people may not be very familiar with water and fertilizer integrated equipment. In fact, the primary function of water and fertilizer integrated equipment is to provide irrigation and fertilization for crops. So, what are the differences between water and fertilizer integrated equipment and traditional irrigation and fertilization methods? Let's explore this together. Traditional irrigation generally relies on cultivation experience. When it is observed that crops are dry, irrigation equipment is turned on to provide water for the crops.

Regarding water and fertilizer integrated equipment, many people engaged in agricultural cultivation should be familiar with it. The primary function of water and fertilizer integrated equipment is to automatically control irrigation and fertilization. Through automated control of irrigation and fertilization, irrigation and fertilization in agriculture are made more reasonable, saving cultivators' work processes and greatly improving the efficiency of irrigation and fertilization! So how exactly does water and fertilizer integrated equipment achieve automated fertilization and irrigation? What is the specific principle? Let's give a detailed introduction to this! Water and fertilizer integrated equipment itself includes irrigation and fertilization, and traditional irrigation often relies on experience, and when it feels that crops need irrigation,

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.
