Drip Irrigation Technology for Fruit Trees
Characteristics of Drip Irrigation

Small irrigation volume and short irrigation cycle. Generally, the flow rate of drippers is liter/hour, and the irrigation time interval depends on different fruit tree types, usually once a day.

Partially moist soil. Drip irrigation only moistens part of the soil near the roots of crops without destroying the soil structure. The soil water, heat and nutrients in the humid area are in good condition, reducing evaporation on the soil surface and saving water.

Low work pressure. The working head of the dripper is meters.

It can be combined with fertilization to accurately deliver the fertilizer required in different periods to the roots.

Two types of drip irrigation

Surface drip irrigation uses drippers installed on water pipes, orifices or drip irrigation bristle emitters to drip water to the ground evenly and slowly. It is formed by dripping into the soil near the roots of crops.

Underground drip irrigation is to bury capillary tubes and emitters centimeters below the surface, and the irrigation water seeps out from the emitters to moisten the soil. This irrigation method can slow down the aging of capillary tubes and emitters, prevent loss, and facilitate field operations. However, there is a problem that once the emitter is clogged, it is inconvenient to find and clean.

Three Drip Irrigation Engineering Systems

A complete drip irrigation engineering system usually consists of four parts: the water source control hub, the pipe network (water transmission and distribution pipeline) system and the emitter.

Water sources are very abundant, and rivers, lakes, canals, wells and springs may be sources of water for drip irrigation. However, it should not be used as a water source if it contains too much dirt, otherwise it will make the water purification equipment too complicated. It can even cause blockage in the drip irrigation system.

The first hub. The first part of drip irrigation work usually includes water pumps, power machine control valves, water purification devices, fertilization devices, measurement and protection equipment.

Pipe network system. The pipe network of a drip irrigation project is generally composed of main pipes, branch pipes and capillary pipes.

Irrigator. The emitter is installed on the capillary tube or connected to the capillary tube through a small connecting tube.

When planning and designing the four-drip irrigation project, first conduct a survey of the planned area and collect relevant information, such as geographical terrain, soil properties, water source conditions, meteorological conditions, fruit tree types, cultivated plant-row spacing, and tree-row spacing. output, etc. Plan and design based on this. The layout of the system is usually initially laid out on a topographic map, and then modified by comparing it with the actual terrain.

The layout of the five systems

Determination of the first hub The location selection of the first hub is mainly based on the principles of saving investment and facilitating management. Generally, the first hub is combined with water conservancy projects.

The arrangement of capillary tubes and irrigation devices should be based on the type of fruit trees and the distance between planting rows. There are usually a single row of capillaries arranged in a straight line, a single row of capillaries arranged in a circular tube, a double row of capillaries arranged in parallel, and a single row of capillaries arranged with microtubules. The emitter is installed on the capillary tube.

Determination of Six Drip Irrigation Systems

The drip irrigation system refers to the total amount of water poured into fruit trees each time throughout the year, and the number of times of irrigation at one irrigation time interval.

The working system of the seven drip irrigation systems is determined

The working system of the system is divided into two types: continuous irrigation and rotating irrigation. Continuous irrigation means that all pipes in the system supply water at the same time. Round irrigation means that the branch pipes are divided into several The groups take turns to provide water, so the economic status of the water source for investment in the project is determined by the different conditions.
