Fruit tree drip irrigation technology What is fruit tree drip irrigation
Fruit tree drip irrigation uses emitters such as drippers, orifices or drip irrigation tapes installed on the capillary tubes of the irrigation system to drip water drop by drop evenly and slowly into the vicinity of the root zone of fruit trees. Irrigation methods in the soil.
What conditions are suitable for drip irrigation in orchards?
Drip irrigation is most suitable for orchards with water shortages and good water quality and management conditions.
What is a dripper? What kind of drippers are commonly used?
A dripper is a kind of emitter for drip irrigation. After the pressure water flow in the capillary tube is energy-dissipated, it irrigates the soil with discontinuous water droplets. It is called a drip emitter, or dripper for short. It is common to lower its head to compensate for pressure. Dripper.
The types of drippers include long channel drippers and orifice drippers. Microtube drippers are also called hair drippers, with an inner diameter of millimeters, and can be inserted into the wall of the capillary tube. The advantage is that the cost is low, and the capillary pipe can be cut and installed sideways, which can improve the integrity of the capillary pipe and bury it underground. The management method is safe and can extend the service life of drip irrigation equipment. Orifice type dripper, the capillary tube is buried underground for fixed use. The inner diameter of the tube is led out of the ground, and the orifice dripper is connected to the tube.
How many drippers need to be placed on each fruit tree?
Generally, each fruit tree is equipped with a dripper. Among them, for fruit trees with large sandiness and large crowns, the number of drippers per plant should be increased, the irrigation quota should be reduced, and the irrigation cycle should be shortened. In orchards with clayey soil, deep soil layers, and small crowns, the number of drippers per plant can be appropriately reduced and the irrigation quota should be increased. , extend the irrigation cycle.
How much flow is required to develop an orchard per hectare?
Determine the scale of drip irrigation based on the water source and its water supply. It is usually appropriate to control hectares of fruit trees with an hourly amount of water.
How to specify a drip irrigation system?
The average monthly total water demand of fruit trees is millimeters for many years. The peak water demand is in the month. The peak water demand intensity is millimeters per day. The average drip irrigation water supply per day is millimeters. The drip irrigation volume per hectare is millimeters per day. Generally, watering is done once a year, and the watering cycle is every day. The water flow rate of the dripper should not exceed liters per hour. When used on the ground, it should not exceed liters per hour, generally liters per hour is enough.
What is canalicular outflow irrigation?
The capillary tube of the micro-irrigation system leads to a conduit with an inner diameter of 1 mm, and the water flows out of the conduit to perform micro-irrigation on the root zone of the fruit trees, also known as spring irrigation. The conduit is located at the lower canopy radius of each fruit tree. The height of the pipe is meters above the ground.

Drip irrigation uses a set of specialized equipment to filter the pressurized water through all levels of water delivery pipe networks (including main pipes (main pipes), branch pipes, capillaries and gate valves, etc.) to the drippers. The dripper drips directly and slowly into the rhizosphere soil of fruit trees or crops. After the water drips into the soil, it penetrates with the help of vertical force, forming a small saturated area under the dripper, and then gradually spreads to the area with developed root system of the crops. Drip irrigation technology uses a series of plastic pipes of different diameters to transport water and fertilizer dissolved in water from the water source directly to the roots of fruit trees or crops through pressure pipes. Water and fertilizer are supplied regularly and rationed as needed, avoiding the water loss caused by canal leakage, water surface evaporation, deep leakage and other aspects of traditional irrigation technology. Since drip irrigation only partially moistens the soil at the root of the crop, the dripping speed is less than the soil imbibition speed, so it does not damage the soil structure. After irrigation, the soil does not harden and can remain loose, thereby improving the soil's water retention capacity and reducing ineffective inter-plant evaporation. The application of drip irrigation technology not only saves water and energy, but also has the advantages of saving labor and water, promoting the development of crop root systems, hindering the reproduction of pests and weeds, and being suitable for use in complex terrain.


Analysis of the economic benefits of drip irrigation for fruit trees shows that the irrigation water utilization coefficient reaches the above level, achieving efficient use of water resources. Take the drip irrigation of grapevines as an example: in terms of labor saving, it is even more obvious. One person works for one yuan. If drip irrigation is not used, bagging and fertilizing all require manual labor. After drip irrigation is used, drip irrigation can be used to water and fertilize at the same time. Labor only needs to do bagging. bags and other work. Each acre of land saves at least one worker, which is yuan. In terms of yield increase, the contrast is more prominent. The yield per mu without drip irrigation is at least 500 jins. After using drip irrigation, the yield is at least 500 jins. Moreover, after using drip irrigation, the grapes are big and round, and the taste is also very good. The market price is yuan per catty, per mu. Increase production yuan.
