First, advantages
1. Water saving, fertilizer saving, labor saving
Drip irrigation is a full-pipe water delivery and local micro-irrigation, which reduces water leakage and loss to a lower limit. At the same time, because the water required by the crop root zone can be supplied in a timely manner, there is no problem of loss of peripheral water, and the water use efficiency is greatly improved. Irrigation can be easily combined with fertilization, that is, the fertilizer is dissolved and poured into the irrigation system. Since the fertilizer is combined with the irrigation water, the fertilizer nutrients are directly and evenly applied to the crop root system, which truly realizes the synchronization of water and fertilizer and greatly improves the effective use of fertilizer. At the same time, because of local control in a small area, farm drip irrigation has less leakage of water and fertilizer, so it can save the amount of fertilizer application and reduce pollution. The use of irrigation and fertilization technology facilitates timely supplementation of expensive trace elements in crops and avoids waste. The drip irrigation system is only controlled manually or automatically by a valve, and combined with fertilization, it can obviously save labor input and reduce production costs.
2.Control temperature and humidity
Traditional ditch irrigation greenhouses have a large amount of irrigation at one time, and the ground surface is kept moist for a long time. Not only the shed temperature and ground temperature decrease too quickly, the rise is slow, but the evaporation is increased, and the indoor humidity is too high, which may easily cause vegetable or flower diseases and insect pests. Because drip irrigation is local micro-irrigation, most of the soil surface remains dry, and the dripper evenly and slowly supplies water to the root soil layer, which has a significant effect on maintaining and recovering ground temperature, reducing water evaporation, and reducing indoor humidity. The use of drip irrigation under the film, that is, the drip irrigation pipe (band) is arranged under the film, the effect is better. In addition, the irrigation drip line can perform high-frequency irrigation due to its convenient operation. The outlet holes are small and the flow velocity is slow. Each irrigation time is relatively long and the soil moisture changes are small. Therefore, the soil in the root zone can be controlled Keep the humidity close to the most suitable for the growth of vegetables and flowers for a long time. Because the indoor air humidity and soil humidity are controlled, the occurrence of pests and diseases can be significantly reduced, and the amount of pesticides can be reduced.
3. Maintain soil structure
Due to the large irrigation volume of traditional gully irrigation, the soil of the facility will be subject to more erosion, compaction and erosion. If the soil is not tilled in time, it will cause serious compaction, decreased air permeability, and damage to the soil structure to a certain extent. Drip irrigation is a kind of micro-irrigation. The water penetrates into the soil slowly and evenly, which can maintain the soil structure and form a suitable soil water, fertilizer, and thermal environment.
2. Improve quality, increase production and efficiency As the application of drip irrigation reduces the amount of water and fertilizer, pesticides and the occurrence of pests and diseases, the quality of the product can be significantly improved. In short, compared with traditional irrigation methods, the use of drip irrigation in greenhouses or greenhouses can greatly increase product output, improve morning market time, and reduce the cost of water, fertilizer, pesticides, and labor costs, so economic and social benefits. Significantly. Protected horticultural drip irrigation technology meets the requirements of high-yield, high-efficiency, high-quality modern agriculture, which is the fundamental reason for its existence and vigorous promotion.

Disadvantages
1. Easy to cause blockage
The blockage of the irrigation device is the most important problem in the current drip irrigation application. When it is serious, the entire system will not work properly or even be scrapped. The cause of the blockage can be physical, biological or chemical. Such as sediment, organic matter or microorganisms in water and chemical sediments. Therefore, water quality requirements are stricter during drip irrigation, and they should generally be filtered, and sedimentation and chemical treatment required if necessary.
2. May cause salt accumulation
Drip tape manufacturer reminds you: When drip irrigation or salty drip irrigation is applied to soils with high salt content, salt will accumulate on the edge of the humid area. If there is light rain, these salts may be damaged. Rush to the root zone of the crop and cause salt damage. At this time, drip irrigation should be continued. Where there is insufficient flushing or where there is not enough rainfall in autumn, do not use drip irrigation on salty soils or use salty drip irrigation.
3. May restrict root system development
Because drip irrigation only moistens part of the soil, and the root system of the crop is water-repellent, this will cause the crop root system to concentrate in the humid area. In addition, in arid areas where there is no agriculture without irrigation, drip irrigation should be properly arranged when applying drip irrigation.
